Optional Request Header in Spring Rest Service
提问by Freephone Panwal
I'm using Spring Restful web service & having request body with request header as shown below:
我正在使用 Spring Restful Web 服务 & 请求正文和请求标头如下所示：
@RequestMapping(value = "/mykey", method = RequestMethod.POST, consumes="applicaton/json")
public ResponseEntity<String> getData(@RequestBody String body, @RequestHeader("Auth") String authorization) {
try {
....
} catch (Exception e) {
....
}
}
I want to pass one more optional request header called "X-MyHeader". How do I specify this optional request header in Spring rest service?
我想传递一个名为“X-MyHeader”的可选请求标头。如何在 Spring rest 服务中指定这个可选的请求头？
Also, how do I pass this same value in response header?? Thanks!
另外，如何在响应标头中传递相同的值？谢谢！
UPDATE: I just found that I can set required=false in request header, so one issue is resolved. Now, the only issue remaining is how do I set the header in the response??
更新：我刚刚发现我可以在请求标头中设置 required=false ，因此解决了一个问题。现在，剩下的唯一问题是如何在响应中设置标头？

@RequestMapping("/something")
public ResponseEntity<String> handle(HttpEntity<byte[]> requestEntity) throws UnsupportedEncodingException {
String requestHeader = requestEntity.getHeaders().getFirst("MyRequestHeader");
byte[] requestBody = requestEntity.getBody();
// do something with request header and body
HttpHeaders responseHeaders = new HttpHeaders();
responseHeaders.set("MyResponseHeader", "MyValue");
return new ResponseEntity<String>("Hello World", responseHeaders, HttpStatus.CREATED);
}
