Question

在过去的几天里，我一直在为此苦苦挣扎，我想我尝试了可以在互联网上找到的每个示例。我正在尝试登录REST并获取授权代码以进行持续的通信。使用邮递员

时可以使用

----从邮递员那里生成代码片段----

POST /api/auth/signin HTTP/1.1
Host: localhost:5000
Content-Type: application/json
cache-control: no-cache
Postman-Token: baffa067-c2a0-4d5c-b321-348682227195
{
    "username": "Test",
    "password": "Testpw"
}------WebKitFormBoundary7MA4YWxkTrZu0gW--

它返回

{"accessToken":"eyJhbGciOiJIUzUxMiJ9.eyJzdWIiOiIxIiwiaWF0IjoxNTQ0Mjc4MTE5LCJleHAiOjE1NDQ4ODI5MTl9.qNQ7MIIsWpYQdeje6Ox88KR9AdNGCSiffjyk__nrdWvP7yoy4Ukk05ZQUISVptOIoBpahFT1OHf_MXVQnW5Izg","tokenType":"Bearer"}

我在CodenameOne项目中的代码是：

 public void onloginActionEvent(com.codename1.ui.events.ActionEvent ev) {
              JSONObject json = new JSONObject();
              try {
                  ConnectionRequest post = new ConnectionRequest(){
                        @Override
                        protected void buildRequestBody(OutputStream os) throws IOException {
                            os.write(json.toString().getBytes("UTF-8"));
                        }

                        @Override
                        protected void readResponse(InputStream input) throws IOException {
                        }

                        @Override
                        protected void postResponse() {                             
                        }
                    };
                    json.put("username", "Test");
                    json.put("password", "Testpw");

                  post.setUrl("http://localhost:5000/api/auth/signin");
                  post.setPost(true);
                  post.setContentType("application/json");
                  post.addArgument("body", json.toString());
                  String bodyToString = json.toString();
                  NetworkManager.getInstance().addToQueueAndWait(post);
                  Map<String,Object> result = new JSONParser().parseJSON(new InputStreamReader(new ByteArrayInputStream(post.getResponseData()), "UTF-8"));
              } catch (Exception ex) {
                  ex.printStackTrace();
              }
          }

使用CodenameOne模拟器网络监视器时，将得到以下结果

您覆盖readResponse而不调用super。这将覆盖读取数据的默认行为。您可以删除该方法或编写用于读取该方法中JSON的逻辑。
