使用 resttemplate 发布请求，但 401 未经授权

Question

String url = "https://api.assembla.com/token?";

RestTemplate restTemplate = new RestTemplate();

MultiValueMap<String, String> body = 
        new LinkedMultiValueMap<String, String>();

body.add("client_id", "myid");
body.add("client_secret", "mysecret");
body.add("grant_type", "client_credentials");
HttpHeaders headers = new HttpHeaders();
headers.add("Accept", "application/json");
headers.add("Content-type", "application/json");
HttpEntity<?> entity = new HttpEntity<Object>(body, headers);

ResponseEntity<JsonResponseType> res = 
        restTemplate.exchange(url, HttpMethod.POST, entity, JsonResponseType.class);

System.out.println("Hello....." + res);

我收到 401 未经授权的错误，有人可以删除它吗

也用

MultiValueMap<String, String> body = 
        new LinkedMultiValueMap<String, String>();

body.add("x-api-key", "myapikey");
body.add("x-api-secret", "myapisecret");
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON);
headers.set("Accept", "application/json");
headers.set("Content-type", "application/json");

HttpEntity<?> entity = new HttpEntity<Object>(body, headers);
entity.getHeaders().setContentType(MediaType.APPLICATION_JSON);
RestTemplate restTemplate = new RestTemplate();
List<HttpMessageConverter<?>> messageConverters = new
        ArrayList<HttpMessageConverter<?>>();

messageConverters.add(new MappingJacksonHttpMessageConverter());
restTemplate.setMessageConverters(messageConverters);
ResponseEntity<JsonResponseType> response =
        restTemplate.exchange(
                url, HttpMethod.POST, entity, JsonResponseType.class);

System.out.println("Hello....." + response);

这也有错误 401 未经授权未找到

我也在用

HttpMethod.POST, requestEntity, YourResponseType.class);
System.out.println("Hello....." + responseEntity);`

RestTemplate restTemplate = new RestTemplate();
List<MediaType> acceptableMediaTypes = new ArrayList<MediaType>();
acceptableMediaTypes.add(MediaType.APPLICATION_JSON);

HttpHeaders headers = new HttpHeaders();
headers.setAccept(acceptableMediaTypes);

HttpEntity<String> requestEntity = new HttpEntity<String>(
        "X-Api-Key:myapikey X-Api-Secret:=my api secret",
        headers);
ResponseEntity<YourResponseType> responseEntity = restTemplate
        .exchange("https://api.assembla.com/v1/spaces.json",

这也有同样的错误

首先要尝试的是删除headers.add("Content-type", "application/json");. 您的实际内容类型是application/x-www-form-urlencoded.

以下代码对我来说很好用：

   RestTemplate restTemplate = new RestTemplate();
   MultiValueMap<String, String> body = new LinkedMultiValueMap<String, String>();
   body.add("client_id", "aViwaUZXir44tcdmr6bg7m");
   body.add("client_secret", "65d952744a49774bcf24bcd32c521619");
   body.add("grant_type", "client_credentials");
   HttpHeaders headers = new HttpHeaders();
   headers.add("Accept", "application/json");
   HttpEntity<?> entity = new HttpEntity<Object>(body, headers);
   ResponseEntity<String> res = restTemplate.exchange(
       "https://api.assembla.com/token?", HttpMethod.POST, entity, String.class);

我什至在这里留下了有效的凭据，因为它们是专为测试而创建的。
