[英]CORS with spring-boot and angularjs not working
我正在嘗試從另一個應用程序(spring-boot 應用程序)(angularjs)調用 REST 端點。 應用程序在以下主機和端口上運行。
http://localhost:8080
http://localhost:50029
我還將spring-security
與 spring-boot 應用程序一起使用。 從 HTML 應用程序中,我可以對 REST 應用程序進行身份驗證,但此后,我仍然無法訪問任何 REST 端點。 例如,我有一個 angularjs 服務定義如下。
adminServices.factory('AdminService', ['$resource', '$http', 'conf', function($resource, $http, conf) {
var s = {};
s.isAdminLoggedIn = function(data) {
return $http({
method: 'GET',
url: 'http://localhost:8080/api/admin/isloggedin',
withCredentials: true,
headers: {
'X-Requested-With': 'XMLHttpRequest'
}
});
};
s.login = function(username, password) {
var u = 'username=' + encodeURI(username);
var p = 'password=' + encodeURI(password);
var r = 'remember_me=1';
var data = u + '&' + p + '&' + r;
return $http({
method: 'POST',
url: 'http://localhost:8080/login',
data: data,
headers: {'Content-Type': 'application/x-www-form-urlencoded'}
});
};
return s;
}]);
angularjs controller 如下所示。
adminControllers.controller('LoginController', ['$scope', '$http', 'AdminService', function($scope, $http, AdminService) {
$scope.username = '';
$scope.password = '';
$scope.signIn = function() {
AdminService.login($scope.username, $scope.password)
.success(function(d,s) {
if(d['success']) {
console.log('ok authenticated, call another REST endpoint');
AdminService.isAdminLoggedIn()
.success(function(d,s) {
console.log('i can access a protected REST endpoint after logging in');
})
.error(function(d, s) {
console.log('huh, error checking to see if admin is logged in');
$scope.reset();
});
} else {
console.log('bad credentials?');
}
})
.error(function(d, s) {
console.log('huh, error happened!');
});
};
}]);
在調用http://localhost:8080/api/admin/isloggedin
時,我得到一個401 Unauthorized
。
在 REST 應用程序端,我有一個 CORS 過濾器,如下所示。
@Component
@Order(Ordered.HIGHEST_PRECEDENCE)
public class CORSFilter implements Filter {
@Override
public void destroy() { }
@Override
public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain)
throws IOException, ServletException {
HttpServletResponse response = (HttpServletResponse) res;
HttpServletRequest request = (HttpServletRequest) req;
response.setHeader("Access-Control-Allow-Origin", "http://localhost:50029");
response.setHeader("Access-Control-Allow-Methods", "POST, PUT, GET, OPTIONS, DELETE");
response.setHeader("Access-Control-Max-Age", "3600");
response.setHeader("Access-Control-Allow-Headers", "X-Requested-With, X-Auth-Token");
response.setHeader("Access-Control-Allow-Credentials", "true");
if(!"OPTIONS".equalsIgnoreCase(request.getMethod())) {
chain.doFilter(req, res);
}
}
@Override
public void init(FilterConfig config) throws ServletException { }
}
我的 spring 安全配置如下所示。
@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private RestAuthenticationEntryPoint restAuthenticationEntryPoint;
@Autowired
private JsonAuthSuccessHandler jsonAuthSuccessHandler;
@Autowired
private JsonAuthFailureHandler jsonAuthFailureHandler;
@Autowired
private JsonLogoutSuccessHandler jsonLogoutSuccessHandler;
@Autowired
private AuthenticationProvider authenticationProvider;
@Autowired
private UserDetailsService userDetailsService;
@Autowired
private PersistentTokenRepository persistentTokenRepository;
@Value("${rememberme.key}")
private String rememberMeKey;
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.csrf().disable()
.exceptionHandling()
.authenticationEntryPoint(restAuthenticationEntryPoint)
.and()
.authorizeRequests()
.antMatchers("/api/admin/**").hasRole("ADMIN")
.antMatchers("/", "/admin", "/css/**", "/js/**", "/fonts/**", "/api/**").permitAll()
.anyRequest().authenticated()
.and()
.formLogin()
.successHandler(jsonAuthSuccessHandler)
.failureHandler(jsonAuthFailureHandler)
.permitAll()
.and()
.logout()
.deleteCookies("remember-me", "JSESSIONID")
.logoutSuccessHandler(jsonLogoutSuccessHandler)
.permitAll()
.and()
.rememberMe()
.userDetailsService(userDetailsService)
.tokenRepository(persistentTokenRepository)
.rememberMeCookieName("REMEMBER_ME")
.rememberMeParameter("remember_me")
.tokenValiditySeconds(1209600)
.useSecureCookie(false)
.key(rememberMeKey);
}
@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth
.authenticationProvider(authenticationProvider);
}
}
所有的處理程序正在做的是寫出一個 JSON 響應,如{success: true}
基於用戶是否登錄、身份驗證失敗或注銷。 RestAuthenticationEntryPoint
如下所示。
@Component
public class RestAuthenticationEntryPoint implements AuthenticationEntryPoint {
@Override
public void commence(HttpServletRequest req, HttpServletResponse resp, AuthenticationException ex)
throws IOException, ServletException {
resp.sendError(HttpServletResponse.SC_UNAUTHORIZED, "Unauthorized");
}
}
關於我缺少什么或做錯了什么的任何想法?

無需額外定義此過濾器,只需添加此類即可。 Spring 將被掃描並為您添加。 簡單的CORS過濾器。 這是示例: spring-enable-cors
我也遇到過類似的情況。 經過研究和測試,這是我的發現:
使用 Spring Boot,啟用全局 CORS 的推薦方法是在 Spring MVC 中聲明並結合細粒度的@CrossOrigin
配置為:
@Configuration public class CorsConfig { @Bean public WebMvcConfigurer corsConfigurer() { return new WebMvcConfigurerAdapter() { @Override public void addCorsMappings(CorsRegistry registry) { registry.addMapping("/**").allowedMethods("GET", "POST", "PUT", "DELETE").allowedOrigins("*") .allowedHeaders("*"); } }; } }
現在,由於您使用的是 Spring Security,您還必須在 Spring Security 級別啟用 CORS 以允許它利用在 Spring MVC 級別定義的配置:
@EnableWebSecurity public class WebSecurityConfig extends WebSecurityConfigurerAdapter { @Override protected void configure(HttpSecurity http) throws Exception { http.cors().and()... } }
這是一個非常優秀的教程,解釋了 Spring MVC 框架中的 CORS 支持。
如果您想在不使用過濾器或不使用配置文件的情況下啟用 CORS,只需添加
@CrossOrigin
到您的控制器頂部,它可以工作。
為了建立在上述其他答案的基礎上,如果您有一個具有 Spring 安全性的 Spring Boot REST 服務應用程序(不是 Spring MVC),那么通過 Spring 安全性啟用 CORS 就足夠了(如果您使用 Spring MVC,那么使用 Yogen 提到的WebMvcConfigurer
bean 可以是要走的路,因為 Spring 安全性將委托給其中提到的 CORS 定義)
因此,您需要有一個執行以下操作的安全配置:
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
//other http security config
http.cors().configurationSource(corsConfigurationSource());
}
//This can be customized as required
CorsConfigurationSource corsConfigurationSource() {
CorsConfiguration configuration = new CorsConfiguration();
List<String> allowOrigins = Arrays.asList("*");
configuration.setAllowedOrigins(allowOrigins);
configuration.setAllowedMethods(singletonList("*"));
configuration.setAllowedHeaders(singletonList("*"));
//in case authentication is enabled this flag MUST be set, otherwise CORS requests will fail
configuration.setAllowCredentials(true);
UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
source.registerCorsConfiguration("/**", configuration);
return source;
}
}
此鏈接有更多信息: https : //docs.spring.io/spring-security/site/docs/current/reference/htmlsingle/#cors
筆記:
UserDetailsService
),則configuration.setAllowCredentials(true);
必須添加測試 Spring boot 2.0.0.RELEASE(即 Spring 5.0.4.RELEASE 和 Spring security 5.0.3.RELEASE)
我使用的是spring boot 2.1.0
,對我spring boot 2.1.0
是
A. 通過以下方式添加 cors 映射:
@Configuration
public class Config implements WebMvcConfigurer {
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**").allowedOrigins("*");
}
}
B. 將以下配置添加到我的HttpSecurity
以實現 spring 安全
.cors().configurationSource(new CorsConfigurationSource() {
@Override
public CorsConfiguration getCorsConfiguration(HttpServletRequest request) {
CorsConfiguration config = new CorsConfiguration();
config.setAllowedHeaders(Collections.singletonList("*"));
config.setAllowedMethods(Collections.singletonList("*"));
config.addAllowedOrigin("*");
config.setAllowCredentials(true);
return config;
}
})
同樣在 Zuul 代理的情況下,您可以使用這個INSTEAD OF A 和 B (只需使用HttpSecurity.cors()
在 Spring 安全中啟用它):
@Bean
public CorsFilter corsFilter() {
final UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
final CorsConfiguration config = new CorsConfiguration();
config.setAllowCredentials(true);
config.addAllowedOrigin("*");
config.addAllowedHeader("*");
config.addAllowedMethod("OPTIONS");
config.addAllowedMethod("HEAD");
config.addAllowedMethod("GET");
config.addAllowedMethod("PUT");
config.addAllowedMethod("POST");
config.addAllowedMethod("DELETE");
config.addAllowedMethod("PATCH");
source.registerCorsConfiguration("/**", config);
return new CorsFilter(source);
}
這對我有用:
@Configuration
public class MyConfig extends WebSecurityConfigurerAdapter {
//...
@Override
protected void configure(HttpSecurity http) throws Exception {
//...
http.cors().configurationSource(new CorsConfigurationSource() {
@Override
public CorsConfiguration getCorsConfiguration(HttpServletRequest request) {
CorsConfiguration config = new CorsConfiguration();
config.setAllowedHeaders(Collections.singletonList("*"));
config.setAllowedMethods(Collections.singletonList("*"));
config.addAllowedOrigin("*");
config.setAllowCredentials(true);
return config;
}
});
//...
}
//...
}
這對我有用。
@EnableWebSecurity
public class WebSecurityConfiguration extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http.cors();
}
}
@Configuration
public class WebConfiguration implements WebMvcConfigurer {
@Override
public void addCorsMappings(CorsRegistry registry) {
registry
.addMapping("/**")
.allowedMethods("*")
.allowedHeaders("*")
.allowedOrigins("*")
.allowCredentials(true);
}
}
對我來說,當使用 spring 安全性時,唯一能 100% 工作的方法是跳過所有額外的過濾器和 bean 的額外絨毛,以及人們一直建議對他們有用但對我不起作用的任何間接“魔法”。
而只是強制它使用普通的StaticHeadersWriter
編寫您需要的標頭:
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http
// your security config here
.authorizeRequests()
.antMatchers(HttpMethod.TRACE, "/**").denyAll()
.antMatchers("/admin/**").authenticated()
.anyRequest().permitAll()
.and().httpBasic()
.and().headers().frameOptions().disable()
.and().csrf().disable()
.headers()
// the headers you want here. This solved all my CORS problems!
.addHeaderWriter(new StaticHeadersWriter("Access-Control-Allow-Origin", "*"))
.addHeaderWriter(new StaticHeadersWriter("Access-Control-Allow-Methods", "POST, GET"))
.addHeaderWriter(new StaticHeadersWriter("Access-Control-Max-Age", "3600"))
.addHeaderWriter(new StaticHeadersWriter("Access-Control-Allow-Credentials", "true"))
.addHeaderWriter(new StaticHeadersWriter("Access-Control-Allow-Headers", "Origin,Accept,X-Requested-With,Content-Type,Access-Control-Request-Method,Access-Control-Request-Headers,Authorization"));
}
}
這是我發現的最直接和明確的方法。 希望它可以幫助某人。
第1步
通過使用@CrossOrigin
注釋來注釋控制器將允許 CORS 配置。
@CrossOrigin
@RestController
public class SampleController {
.....
}
第2步
Spring 已經有了 CorsFilter,盡管您可以將自己的 CorsFilter 注冊為 bean 以提供您自己的配置,如下所示。
@Bean
public CorsFilter corsFilter() {
final UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
final CorsConfiguration config = new CorsConfiguration();
config.setAllowedOrigins(Collections.singletonList("http://localhost:3000")); // Provide list of origins if you want multiple origins
config.setAllowedHeaders(Arrays.asList("Origin", "Content-Type", "Accept"));
config.setAllowedMethods(Arrays.asList("GET", "POST", "PUT", "OPTIONS", "DELETE", "PATCH"));
config.setAllowCredentials(true);
source.registerCorsConfiguration("/**", config);
return new CorsFilter(source);
}
在我們的 Spring Boot 應用程序中,我們像這樣設置了 CorsConfigurationSource。
首先添加allowedOrigns
然后設置applyPermitDefaultValues()
順序讓 Spring 為允許的標頭、公開的標頭、允許的方法等設置默認值,因此我們不必指定這些。
public CorsConfigurationSource corsConfigurationSource() {
CorsConfiguration configuration = new CorsConfiguration();
configuration.setAllowedOrigins(Arrays.asList("http://localhost:8084"));
configuration.applyPermitDefaultValues();
UrlBasedCorsConfigurationSource configurationSource = new UrlBasedCorsConfigurationSource();
configurationSource.registerCorsConfiguration("/**", configuration);
return configurationSource;
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.antMatchers("/api/**")
.access("@authProvider.validateApiKey(request)")
.anyRequest().authenticated()
.and().cors()
.and().csrf().disable()
.httpBasic().authenticationEntryPoint(authenticationEntryPoint);
http.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
}
檢查這個:
@Override
protected void configure(HttpSecurity httpSecurity) throws Exception {
...
.antMatchers(HttpMethod.OPTIONS, "/**").permitAll()
...
}
在您的@EnableWebSecurity 類中擴展 WebSecurityConfigurerAdapter 類並覆蓋 configure() 方法將起作用:以下是示例類
@Override
protected void configure(final HttpSecurity http) throws Exception {
http
.csrf().disable()
.exceptionHandling();
http.headers().cacheControl();
@Override
public CorsConfiguration getCorsConfiguration(final HttpServletRequest request) {
return new CorsConfiguration().applyPermitDefaultValues();
}
});
}
}
如果您的程序最初不使用 spring 安全性並且負擔不起代碼更改的費用,那么創建一個簡單的反向代理就可以解決問題。 就我而言,我使用了具有以下配置的 Nginx:
http {
server {
listen 9090;
location / {
if ($request_method = 'OPTIONS') {
add_header 'Access-Control-Allow-Origin' '*';
add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
#
# Custom headers and headers various browsers *should* be OK with but aren't
#
add_header 'Access-Control-Allow-Headers' 'DNT,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range';
#
# Tell client that this pre-flight info is valid for 20 days
#
add_header 'Access-Control-Max-Age' 1728000;
add_header 'Content-Type' 'text/plain; charset=utf-8';
add_header 'Content-Length' 0;
return 204;
}
if ($request_method = 'POST') {
add_header 'Access-Control-Allow-Origin' '*';
add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
add_header 'Access-Control-Allow-Headers' 'DNT,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range';
add_header 'Access-Control-Expose-Headers' 'Content-Length,Content-Range';
}
if ($request_method = 'GET') {
add_header 'Access-Control-Allow-Origin' '*';
add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
add_header 'Access-Control-Allow-Headers' 'DNT,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range';
add_header 'Access-Control-Expose-Headers' 'Content-Length,Content-Range';
}
proxy_pass http://localhost:8080;
}
}
}
我的程序收聽:8080 。
REF: Nginx 上的 CORS
此答案復制了@abosancic 的答案,但增加了額外的安全性以避免 CORS 漏洞利用。
提示 1:不要在未檢查允許訪問的主機列表的情況下按原樣反映傳入的 Origin。
提示 2:僅允許對列入白名單的主機進行憑據請求。

public SimpleCORSFilter() {

allowedOrigins = new ArrayList<>();
allowedOrigins.add("https://mysafeorigin.com");
allowedOrigins.add("https://itrustthissite.com");
}
@Override
public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
HttpServletRequest request = (HttpServletRequest) req;
HttpServletResponse response = (HttpServletResponse) res;
String allowedOrigin = getOriginToAllow(request.getHeader("Origin"));
if(allowedOrigin != null) {
response.setHeader("Access-Control-Allow-Origin", allowedOrigin);
response.setHeader("Access-Control-Allow-Credentials", "true");
}
response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");
response.setHeader("Access-Control-Max-Age", "3600");
response.setHeader("Access-Control-Allow-Headers", "Content-Type, Accept, X-Requested-With, remember-me");

}
@Override

}
@Override
public void destroy() {
}
public String getOriginToAllow(String incomingOrigin) {
if(allowedOrigins.contains(incomingOrigin.toLowerCase())) {
return incomingOrigin;
} else {
return null;
}
}
}
只需創建一個類,就像這樣,一切都會好起來的:
@Component
@Order(Ordered.HIGHEST_PRECEDENCE)
public class MyCorsConfig implements Filter {
@Override
public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
final HttpServletResponse response = (HttpServletResponse) res;
response.setHeader("Access-Control-Allow-Origin", "*");
response.setHeader("Access-Control-Allow-Methods", "POST, PUT, GET, OPTIONS, DELETE");
response.setHeader("Access-Control-Allow-Headers", "Authorization, Content-Type, enctype");
response.setHeader("Access-Control-Max-Age", "3600");
if (HttpMethod.OPTIONS.name().equalsIgnoreCase(((HttpServletRequest) req).getMethod())) {
response.setStatus(HttpServletResponse.SC_OK);
} else {
chain.doFilter(req, res);
}
}
@Override
public void destroy() {
}
@Override
public void init(FilterConfig config) throws ServletException {
}
}
為了禁用 Spring boot 和 React 之間的 CORS,這對我有用
@Configuration
public class CorsConfig implements WebMvcConfigurer {
/**
* Overriding the CORS configuration to exposed required header for ussd to work
*
* @param registry CorsRegistry
*/
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**")
.allowedOrigins("*")
.allowedMethods("*")
.allowedHeaders("*")
.allowCredentials(true)
.maxAge(4800);
}
}
我還必須修改安全配置,如下所示:
@Override
protected void configure(HttpSecurity http) throws Exception {
http.csrf().disable()
.cors().configurationSource(new CorsConfigurationSource() {
@Override
public CorsConfiguration getCorsConfiguration(HttpServletRequest request) {
CorsConfiguration config = new CorsConfiguration();
config.setAllowedHeaders(Collections.singletonList("*"));
config.setAllowedMethods(Collections.singletonList("*"));
config.addAllowedOrigin("*");
config.setAllowCredentials(true);
return config;
}
}).and()
.antMatcher("/api/**")
.authorizeRequests()
.anyRequest().authenticated()
.and().httpBasic()
.and().sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)
.and().exceptionHandling().accessDeniedHandler(apiAccessDeniedHandler());
}
我很驚訝地發現 Eduardo Dennis 指出了最新的解決方案,該解決方案更簡單,並且不需要編寫自己的過濾器類:它使用的是
org.springframework.web.bind.annotation.CrossOrigin
注釋and().cors()
到您的 Spring Security 配置中。這就是你所要做的!
您可以像這樣使用@CrossOrigin
注釋:
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
@RequestMapping("/api")
@CrossOrigin
public class BackendController {
...
}
如果要配置allowedHeaders
、 methods
、 origins
等,只需將這些值添加到注釋中,如下所示: @CrossOrigin(origins = "http://localhost:50029", maxAge = 3600)
。
使用@CrossOrigin
注解,Spring Security 配置變得非常簡單。 只需將and().cors()
到您的WebSecurityConfig.java
類:
@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.csrf().disable()
.and().cors()
...
}
就這樣! 您可以刪除您的 Filter/CORSFilter 類。 如果要添加全局配置,也可以聲明CorsConfigurationSource
。 請參閱這個很好的答案或Sébastien Deleuze 的這篇博文)。 Spring 開發人員也明確指出:
這種方法取代了之前推薦的基於過濾器的方法。
因此,接受的答案已過時。 這里還有一個完整的示例項目: https : //github.com/jonashackt/microservice-api-spring-boot
要全局啟用 CORS,您需要在兩個地方進行更改:
1. 彈簧靴:
@Configuration
public class CorsConfiguration extends WebMvcConfigurationSupport {
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**").allowedOrigins("*").allowedMethods("*")
.allowCredentials(true);
}
}
你可以在WebMvcConfigurerAdapter
做同樣的WebMvcConfigurerAdapter
,或者創建WebMvcConfigurer
bean。
2. 春季安全
@Override
protected void configure(HttpSecurity http) throws Exception {
http.cors().and()
.authorizeRequests()
.antMatchers(HttpMethod.OPTIONS).permitAll() //Permits your preflight request
}
在 Spring Boot 2.3.3.RELEASE 上工作
簡單的方法是在您的 spring 引導應用程序類(帶有@SpringBootApplication 的類)中創建一個 bean,如下所示:
注意:我在“setAllowedOrigins()”下面指定了“http://localhost.4200”,因為我在 localhost 上運行應用程序並使用 angular 默認端口。
@Bean
public CorsFilter corsFilter(){
CorsConfiguration corsConfiguration = new CorsConfiguration();
corsConfiguration.setAllowCredentials(true);
corsConfiguration.setAllowedOrigins(Arrays.asList("http://localhost:4200"));
corsConfiguration.setAllowedHeaders(Arrays.asList("Origin","Access-Control-Allow-Origin","Content-Type",
"Accept", "Authorization", "Origin, Accept", "X-Requested-With",
"Access-Control-Request-Method", "Access-Control-Request-Headers"));
corsConfiguration.setExposedHeaders(Arrays.asList("Origin", "Content-Type", "Accept","Authorization",
"Access-Control-Allow-Origin", "Access-Control-Allow-Origin", "Access-Control-Allow-Credentials"));
corsConfiguration.setAllowedMethods(Arrays.asList("GET", "POST","PUT","DELETE","OPTIONS"));
UrlBasedCorsConfigurationSource urlBasedCorsConfigurationSource = new UrlBasedCorsConfigurationSource();
urlBasedCorsConfigurationSource.registerCorsConfiguration("/**", corsConfiguration);
return new CorsFilter(urlBasedCorsConfigurationSource);
}
您可以在 sprıng 引導中的每個 restController class 上使用此注釋
@CrossOrigin("*")
如果您使用 spring 安全性,您需要在任何具有擴展extends WebSecurityConfigurerAdapter
的 class 上使用它
@Bean
CorsConfigurationSource corsConfigurationSource() {
CorsConfiguration configuration = new CorsConfiguration();
configuration.setAllowedOrigins(Arrays.asList("https://example.com"));
configuration.setAllowedMethods(Arrays.asList("GET","POST"));
UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
source.registerCorsConfiguration("/**", configuration);
return source;
}
