[英]Spring security OAuth2 accept JSON
我从Spring OAuth2开始。 我想以app / json格式将用户名和密码发送到POST正文中的/ oauth / token端点。
curl -X POST -H "Authorization: Basic YWNtZTphY21lc2VjcmV0" -H "Content-Type: application/json" -d '{
"username": "user",
"password": "password",
"grant_type": "password"
}' "http://localhost:9999/api/oauth/token"
那可能吗？
你能给我一个建议吗？
解决方案（不确定是否正确，但它是否正常工作）：
资源服务器配置：
@Configuration
public class ServerEndpointsConfiguration extends ResourceServerConfigurerAdapter {
@Autowired
JsonToUrlEncodedAuthenticationFilter jsonFilter;
@Override
public void configure(HttpSecurity http) throws Exception {
http
.addFilterBefore(jsonFilter, ChannelProcessingFilter.class)
.csrf().and().httpBasic().disable()
.authorizeRequests()
.antMatchers("/test").permitAll()
.antMatchers("/secured").authenticated();
}
}
过滤：
@Component
@Order(value = Integer.MIN_VALUE)
public class JsonToUrlEncodedAuthenticationFilter implements Filter {
@Override
public void init(FilterConfig filterConfig) throws ServletException {
}
@Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException,
ServletException {
if (Objects.equals(request.getContentType(), "application/json") && Objects.equals(((RequestFacade) request).getServletPath(), "/oauth/token")) {
InputStream is = request.getInputStream();
ByteArrayOutputStream buffer = new ByteArrayOutputStream();
int nRead;
byte[] data = new byte[16384];
while ((nRead = is.read(data, 0, data.length)) != -1) {
buffer.write(data, 0, nRead);
}
buffer.flush();
byte[] json = buffer.toByteArray();
HashMap<String, String> result = new ObjectMapper().readValue(json, HashMap.class);
HashMap<String, String[]> r = new HashMap<>();
for (String key : result.keySet()) {
String[] val = new String[1];
val[0] = result.get(key);
r.put(key, val);
}
String[] val = new String[1];
val[0] = ((RequestFacade) request).getMethod();
r.put("_method", val);
HttpServletRequest s = new MyServletRequestWrapper(((HttpServletRequest) request), r);
chain.doFilter(s, response);
} else {
chain.doFilter(request, response);
}
}
@Override
public void destroy() {
}
}
请求包装器：
public class MyServletRequestWrapper extends HttpServletRequestWrapper {
private final HashMap<String, String[]> params;
public MyServletRequestWrapper(HttpServletRequest request, HashMap<String, String[]> params) {
super(request);
this.params = params;
}
@Override
public String getParameter(String name) {
if (this.params.containsKey(name)) {
return this.params.get(name)[0];
}
return "";
}
@Override
public Map<String, String[]> getParameterMap() {
return this.params;
}
@Override
public Enumeration<String> getParameterNames() {
return new Enumerator<>(params.keySet());
}
@Override
public String[] getParameterValues(String name) {
return params.get(name);
}
}
授权服务器配置（禁用/ oauth / token端点的基本身份验证：
@Configuration
public class AuthorizationServerConfiguration extends AuthorizationServerConfigurerAdapter {
...
@Override
public void configure(AuthorizationServerSecurityConfigurer oauthServer) throws Exception {
oauthServer.allowFormAuthenticationForClients(); // Disable /oauth/token Http Basic Auth
}
...
}
从OAuth 2规范来看，
客户端通过发送请求向令牌端点发出请求
以下参数使用“application / x-www-form-urlencoded”
访问令牌请求应使用application/x-www-form-urlencoded 。
在Spring安全性中，资源所有者密码凭据授权流由Spring Security中的ResourceOwnerPasswordTokenGranter#getOAuth2Authentication处理：
protected OAuth2Authentication getOAuth2Authentication(AuthorizationRequest clientToken) {
Map parameters = clientToken.getAuthorizationParameters();
String username = (String)parameters.get("username");
String password = (String)parameters.get("password");
UsernamePasswordAuthenticationToken userAuth = new UsernamePasswordAuthenticationToken(username, password);
您可以发送username和password来请求参数。
如果您确实需要使用JSON，则有一种解决方法。 如您所见，从请求参数中检索username和password 。 因此，如果将它们从JSON主体传递到请求参数，它将起作用。
这个想法如下：
HttpRequestWrapper 。 该类允许您包装原始请求并从JSON获取参数。 HttpRequestWrapper的子类中，在请求体中解析您的JSON以获取username ， password和grant_type ，并将它们与原始请求参数一起放入新的HashMap 。 然后，覆盖getParameterValues ， getParameter ， getParameterNames和getParameterMap以从新的HashMap返回值 希望这可以提供帮助
您也可以修改@ jakub-kopřiva解决方案以支持oauth的http basic auth。
资源服务器配置：
@Configuration
public class ServerEndpointsConfiguration extends ResourceServerConfigurerAdapter {
@Autowired
JsonToUrlEncodedAuthenticationFilter jsonFilter;
@Override
public void configure(HttpSecurity http) throws Exception {
http
.addFilterAfter(jsonFilter, BasicAuthenticationFilter.class)
.csrf().disable()
.authorizeRequests()
.antMatchers("/test").permitAll()
.antMatchers("/secured").authenticated();
}
}
使用内部RequestWrapper进行过滤
@Component
public class JsonToUrlEncodedAuthenticationFilter extends OncePerRequestFilter {
@Override
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {
if (Objects.equals(request.getServletPath(), "/oauth/token") && Objects.equals(request.getContentType(), "application/json")) {
byte[] json = ByteStreams.toByteArray(request.getInputStream());
Map<String, String> jsonMap = new ObjectMapper().readValue(json, Map.class);;
Map<String, String[]> parameters =
jsonMap.entrySet().stream()
.collect(Collectors.toMap(
Map.Entry::getKey,
e -> new String[]{e.getValue()})
);
HttpServletRequest requestWrapper = new RequestWrapper(request, parameters);
filterChain.doFilter(requestWrapper, response);
} else {
filterChain.doFilter(request, response);
}
}
private class RequestWrapper extends HttpServletRequestWrapper {
private final Map<String, String[]> params;
RequestWrapper(HttpServletRequest request, Map<String, String[]> params) {
super(request);
this.params = params;
}
@Override
public String getParameter(String name) {
if (this.params.containsKey(name)) {
return this.params.get(name)[0];
}
return "";
}
@Override
public Map<String, String[]> getParameterMap() {
return this.params;
}
@Override
public Enumeration<String> getParameterNames() {
return new Enumerator<>(params.keySet());
}
@Override
public String[] getParameterValues(String name) {
return params.get(name);
}
}
}
此外，您还需要允许x-www-form-urlencoded身份验证
@Configuration
public class AuthorizationServerConfiguration extends AuthorizationServerConfigurerAdapter {
...
@Override
public void configure(AuthorizationServerSecurityConfigurer oauthServer) throws Exception {
oauthServer.allowFormAuthenticationForClients();
}
...
}
使用这种方法，您仍然可以使用基本身份验证来获取oauth令牌，并使用json请求令牌，如下所示：
标题：
Authorization: Basic bG9yaXpvbfgzaWNwYQ==
身体：
{
"grant_type": "password",
"username": "admin",
"password": "1234"
}
使用Spring Security 5，我只需添加.allowFormAuthenticationForClients（）+另一个答案中提到的JsontoUrlEncodedAuthenticationFilter，除了x-form post数据外，还要接受json。 无需注册资源服务器或任何其他内容。
您可以修改@ jakub-kopřiva解决方案，仅使用以下代码实现授权服务器。
@Configuration
@Order(Integer.MIN_VALUE)
public class AuthorizationServerSecurityConfiguration
extends org.springframework.security.oauth2.config.annotation.web.configuration.AuthorizationServerSecurityConfiguration {
@Autowired
JsonToUrlEncodedAuthenticationFilter jsonFilter;
@Override
protected void configure(HttpSecurity httpSecurity) throws Exception {
httpSecurity
.addFilterBefore(jsonFilter, ChannelProcessingFilter.class);
super.configure(httpSecurity);
}
}
您好基于@JakubKopřiva回答我已经做了改进，以创建有效的集成测试。 您知道，Catalina RequestFacade在Junit中抛出一个错误，并且mockmvc使用的MockHttpServletRequest不包含我在过滤器中预期的字段“request”（因此在使用getDeclaredField（）时抛出NoSuchFieldException）： Field f = request.getClass().getDeclaredField("request");
这就是我使用“Rest Assured”的原因。 但是在这一点上我遇到了另一个问题，即无论出于何种原因，'application / json'中的内容类型被覆盖到'application / json; charset = utf8'即使我使用MediaType.APPLICATION_JSON_VALUE 。 但是，该条件会查找类似于'application / json; charset = UTF-8'的内容，它位于MediaType.APPLICATION_JSON_UTF8_VALUE ，总之，这将始终为false。
因此，当我用PHP编码时，我的行为与以往一样，并且我对字符串进行了规范化（所有字符都是小写，没有空格）。 在此之后，集成测试最终通过。
