。我 试图Instagram通过Spring Android 从API

获取访问令牌。来自Instagram文档的请求是这样的：

curl \\-F 'client\_id=CLIENT-ID' \\

\-F 'client\_secret=CLIENT-SECRET' \\

\-F 'grant\_type=authorization\_code' \\

\-F 'redirect\_uri=YOUR-REDIRECT-URI' \\

\-F 'code=CODE' \\https://api.instagram.com/oauth/access\_token

这是我的请求访问令牌(成功获取请求令牌后)：

MultiValueMap mvm = new LinkedMultiValueMap();

mvm.add("client\_id", INSTAGRAM\_CILENT\_ID);

mvm.add("client\_secret", INSTAGRAM\_SECRET);

mvm.add("grant\_type", "authorization\_code");

mvm.add("redirect\_uri", CALLBACKURL);

mvm.add("code", requestToken);

InstagramResult result = restTemplate .postForObject("https://api.instagram.com/oauth/access\_token", mvm, InstagramResult .class);

结果映射类：

public class InstagramLogin \{

public String access\_token;

public InstagramUser user;

public class InstagramUser \{

public String id;

public String username;

public String full\_name;

public String profile\_picture;

其余模板：

RestTemplate restTemplate = new RestTemplate();

final List> listHttpMessageConverters = new ArrayList< HttpMessageConverter> >();

listHttpMessageConverters.add(new GsonHttpMessageConverter());

listHttpMessageConverters.add(new FormHttpMessageConverter());

listHttpMessageConverters.add(new StringHttpMessageConverter());

restTemplate.setMessageConverters(listHttpMessageConverters);

但是我总是收到400错误的请求错误。这是我的堆栈跟踪：

P / s：我确定我的参数值正确，因为我通过curl进行了测试，并且效果很好。
