java Spring云REST:400，同时请求JWT令牌

2 周，1 日 Questions & Answers

我试图从身份验证服务接收令牌对象，但一直收到400条消息。有了邮递员，这样的头+体的请求就可以了

请求代码：

    ...
    HttpHeaders httpHeaders = new HttpHeaders();

    String auth = "app" + ":" + "thisissecret";
    byte[] encodedAuth = Base64.encodeBase64(auth.getBytes(Charset.forName("US-ASCII")));
    String authHeader = "Basic " + new String(encodedAuth);
    httpHeaders.set("Authorization", authHeader);

    Map <String, Object> body = new HashMap <>();
    body.put("grant_type", "password");
    body.put("scope", "webclient");
    body.put("username", authEntity.getUsername());
    body.put("password", authEntity.getPassword());

    HttpEntity <Map> requestEntity = new HttpEntity <>(body, httpHeaders);

    ResponseEntity <Token> loginResponse = restTemplate.exchange(AUTHORIZATION_URL, HttpMethod.POST, requestEntity, Token.class);

最后一行是产生400错误的原因

下面是Token类：

public class Token {

    private String accessToken;
    private String tokenType;
    private String refreshToken;
    private String expiresIn;
    private String scope;
    private String organisationId;
    private String jti;

    ... getters / setters

下面是响应json对象的样子：

{
  "access_token": "*****",
  "token_type": "bearer",
  "refresh_token": "*****",
  "expires_in": 43199,
  "scope": "webclient",
  "organisationId": "*****",
  "jti": "***"
}

例外本身：

    我已经用这个代码解决了这个问题。请注意“MultiValueMap”和“RestTemplate”

    ClientHttpRequestFactory requestFactory = new 
HttpComponentsClientHttpRequestFactory(HttpClients.createDefault());
RestTemplate restTemplate = new RestTemplate(requestFactory);
HttpHeaders httpHeaders = new HttpHeaders();

String auth = "app" + ":" + "thisissecret";
byte[] encodedAuth = Base64.encodeBase64(auth.getBytes(Charset.forName("US-ASCII")));
httpHeaders.setContentType(MediaType.APPLICATION_FORM_URLENCODED);
String authorisation = "Basic " + new String(encodedAuth);
httpHeaders.add("authorization", authorisation);
MultiValueMap <String, String> body = new LinkedMultiValueMap <>();
body.add("scope", "webclient");
body.add("grant_type", "password");
body.add("username", authEntity.getUsername());
body.add("password", authEntity.getPassword());

HttpEntity <MultiValueMap <String, String>> requestEntity = new HttpEntity <>(body, httpHeaders);

ResponseEntity <Token> loginResponse = null;

try {
    loginResponse = restTemplate.exchange(AUTHORIZATION_URL, HttpMethod.POST, requestEntity, Token.class);
} catch (HttpClientErrorException ex) {
    log.error("Exception: {}", ex.getLocalizedMessage());
    response.setStatus(HttpServletResponse.SC_UNAUTHORIZED);
}
