如何从http响应实体获取数据?

Question

我使用SpringBoot从我的客户端获取访问令牌。我无法将访问令牌与响应实体分开。是否有办法单独获取AccessToken数据?

代码如下:

public ResponseEntity generate_Access_token() {

String url = "https://zoom.us/oauth/token";
RestTemplate restTemplate = new RestTemplate();
HttpHeaders headers = new HttpHeaders();
final Gson gson = new Gson();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);
MultiValueMap<String, String> map= new LinkedMultiValueMap<String, String>();
map.add("grant_type", "account_credentials");
map.add("client_id", "XXX");
map.add("client_secret", "XXX");
map.add("account_id", "XXX");

HttpEntity<MultiValueMap<String, String>> request = new HttpEntity<MultiValueMap<String, String>>(map, headers);
ResponseEntity<String> response = restTemplate.postForEntity( url, request , String.class );

//ResponseEntity<String> response_data=new ResponseEntity<String>(response.toString(), HttpStatus.CREATED);     
ResponseEntity<AccessTokenResponse> response_data = restTemplate.postForEntity( url, request , AccessTokenResponse.class );

return response_data.getAccessToken();





}
class AccessTokenResponse{
@JsonProperty("access_token")
String accessToken;
//other props you are interested in
//+ getters/setters
public String getAccessToken() {
return accessToken;
}
public void setAccessToken(String accessToken) {
this.accessToken = accessToken;
}

}}

反应:

让您的生活更轻松，而不是更困难-使用普通的DTO

class AccessTokenResponse{
@JsonProperty("access_token");
String accessToken
//other props you are interested in
//+ getters/setters
}

和

AccessTokenResponse response = restTemplate.postForObject( url, request , AccessTokenResponse.class );

response.getAccessToken(); //here you have it
