使用 Node.js 时出现 Android-volley 发布错误

Question

我知道这个问题可能已被问过多次，但似乎没有一个解决方案适合我。在我的 android volley post 请求中，我传递了用户名和密码，但每次我单击登录时，它总是说“无效的用户名和密码”，即使凭据是正确的并且它与 postman 一起工作得很好。这是我的代码如下:

登录 Node.js

router.post('/login', function(req,res,next){
  var user = {
    username: req.body.username,
    password: req.body.password
  };

  connection.query("SELECT id, fullname, username, email_address, createdAt FROM users WHERE username=?  OR email_address=? AND password=? LIMIT 1",[user.username, user.username, user.password], function(err, rows, field){
      if(err) throw err;
      if(rows.length > 0){
        res.json({
            success: '1',
            message: 'Login Successful',
            id: rows[0],
            fullname: rows[1],
            username: rows[2],
            email: rows[3],
            createdAt: rows[4]
        });
      }else{
        res.json({
            success: '0',
            message: 'Invalid username or password'
        });
      }
  });
});

客户端登录(android):

private void login(final String uname, final String upass) {
    //192.168.1.101:5000/api/users/1
   final String url = "http://192.168.1.100:5000/api/users/login";
   RequestQueue queue = Volley.newRequestQueue(getActivity());

    JsonObjectRequest rq = new JsonObjectRequest(Request.Method.POST, url, null, new Response.Listener<JSONObject>() {
        @Override
        public void onResponse(JSONObject response) {
            try {
              if(response.getString("success") != null) {
                final int success = Integer.parseInt(response.getString("success"));
                    if (success == 1) {
                        JSONObject uid = response.getJSONObject("id");
                        int id = uid.getInt("id");
                        String fullname = uid.getString("fullname");
                        String username = uid.getString("username");
                        String email = uid.getString("email");
                        String createdAt = uid.getString("createdAt");
                        SuperToast successToast = new SuperToast(getActivity(), Style.getStyle(Style.BLUE, SuperToast.Animations.FLYIN));
                        //successToast.setText(id + " " + fullname + " " + username + " " + email + " " + createdAt);
                        successToast.setText(response.getString("message"));
                        successToast.setDuration(SuperToast.Duration.LONG);
                        successToast.setGravity(Gravity.CENTER, 0, 0);
                        successToast.show();
                    } else if (success == 0) {
                        SuperToast errorToast = new SuperToast(getActivity(), Style.getStyle(Style.BLUE, SuperToast.Animations.FLYIN));
                        errorToast.setText(response.getString("message"));
                        errorToast.setDuration(SuperToast.Duration.MEDIUM);
                        errorToast.setGravity(Gravity.CENTER, 0, 0);
                        errorToast.show();
                    } else {
                        SuperToast errorToast = new SuperToast(getActivity(), Style.getStyle(Style.BLUE, SuperToast.Animations.FLYIN));
                        errorToast.setText("Invalid Request");
                        errorToast.setDuration(SuperToast.Duration.MEDIUM);
                        errorToast.setGravity(Gravity.CENTER, 0, 0);
                        errorToast.show();
                    }
                }
            } catch (JSONException ex) {
                ex.printStackTrace();
            }
        }
    }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            SuperToast.create(getActivity(), error.getMessage(), SuperToast.Duration.LONG).show();
        }
    }) {
        @Override
        public Map<String, String> getHeaders() throws AuthFailureError {
            HashMap<String, String> headers = new HashMap<String, String>();
            headers.put("Content-Type", "application/json; charset=utf-8");
            return headers;
        }

        @Override
        protected Map<String, String> getParams() throws AuthFailureError {
            Map<String, String> params = new HashMap<String, String>();
            params.put("username", uname);
            params.put("password", upass);
            return params;
        }
    };
    //MySingleton.getInctance(getActivity().getApplicationContext()).addToRequestQueue(rq);
    queue.add(rq);
}

任何帮助将不胜感激，提前谢谢您。

您没有在请求正文中发送用户名和密码:

JsonObjectRequest rq = new JsonObjectRequest(Request.Method.POST, url, null, new Response.Listener<JSONObject>() {

创建正文并设置请求:

JSONObject body = new JSONObject();
body.put("username", uname);
body.put("password", upass);

JsonObjectRequest rq = new JsonObjectRequest(Request.Method.POST, url, body, new Response.Listener<JSONObject>() {
