[英]Serve yaml file with Spring REST endpoint
I want to serve a .yaml file via a REST endpoint with Spring, I know that it cannot be directly displayed in a browser (just talking about Chrome here), since it doesn't support display of yaml files.我想通过带有 Spring 的 REST 端点提供 .yaml 文件,我知道它不能直接显示在浏览器中(这里只讨论 Chrome),因为它不支持 yaml 文件的显示。 I have included what I think is the necessary library for this purpose
compile group: 'com.fasterxml.jackson.dataformat', name: 'jackson-dataformat-yaml', version: '2.9.9'
.我已经包含了我认为为此目的
compile group: 'com.fasterxml.jackson.dataformat', name: 'jackson-dataformat-yaml', version: '2.9.9'
所需的库compile group: 'com.fasterxml.jackson.dataformat', name: 'jackson-dataformat-yaml', version: '2.9.9'
。
If I open the endpoint /v2/api-doc
in the browser, it will prompt me, to download a file named exactly as the endpoint /v2/api-doc
.如果我在浏览器中打开端点
/v2/api-doc
,它会提示我下载一个与端点/v2/api-doc
完全相同/v2/api-doc
。 It contains the correct content.它包含正确的内容。
Question: Is there a way to correctly transfer the .yaml file, so that the user will be prompted to safe myfile.yaml?问题:有没有办法正确传输.yaml文件,提示用户安全myfile.yaml?
@RequestMapping(value = "/v2/api-doc", produces = "application/x-yaml")
public ResponseEntity<String> produceApiDoc() throws IOException {
byte[] fileBytes;
try (InputStream in = getClass().getResourceAsStream("/restAPI/myfile.yaml")) {
fileBytes = IOUtils.toByteArray(in);
}
if (fileBytes != null) {
String data = new String(fileBytes, StandardCharsets.UTF_8);
return new ResponseEntity<>(data, HttpStatus.OK);
} else {
return new ResponseEntity<>(HttpStatus.NOT_FOUND);
}
}
You should set a Content-Disposition
header (and I recommend using ResourceLoader
to load resources in Spring Framework).您应该设置一个
Content-Disposition
标头(我建议使用ResourceLoader
在 Spring Framework 中加载资源)。
Example:例子:
@RestController
public class ApiDocResource {
private final ResourceLoader resourceLoader;
public ApiDocResource(ResourceLoader resourceLoader) {
this.resourceLoader = resourceLoader;
}
@GetMapping(value = "/v2/api-doc", produces = "application/x-yaml")
public ResponseEntity produceApiDoc() throws IOException {
Resource resource = resourceLoader.getResource("classpath:/restAPI/myfile.yaml");
if (resource.exists()) {
return ResponseEntity
.ok()
.contentType(MediaType.parseMediaType("application/x-yaml"))
.header("Content-Disposition", "attachment; filename=myfile.yaml")
.body(new InputStreamResource(resource.getInputStream()));
} else {
return new ResponseEntity<>(HttpStatus.NOT_FOUND);
}
}
}
