API 不支持的授权类型

Question

我正在尝试从服务器响应中获取令牌，它适用于 postMan ，但是当使用 android 调试它时会出错：

unsupported_grant_type

这是我的代码：

HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost(LoginURL);
post.setHeader("Content-Type", "application/x-www-form-urlencoded");
// post.setHeader("Accept", "application/x-www-form-urlencoded");
JSONObject obj = new JSONObject();
try {
    obj.put("grant_type", "password");
    obj.put("password", PasswordEditText);
    obj.put("username", EmailEditText+"gfg");

    post.setEntity(new StringEntity(obj.toString(), "UTF-8"));
    HttpResponse response = client.execute(post);
    HttpEntity entity = response.getEntity();
    results = EntityUtils.toString(entity);
    myObject = new JSONObject(results);

Answer 1

终于找到了解决办法：

替换：

  post.setEntity(new StringEntity(obj.toString(), "UTF-8"));

与：

                post.setEntity(new StringEntity("grant_type=password&username=0000@gmail.com&password=00000", "UTF-8"));
