Question

您好，我正在使用凌空库从android发送一个json对象。我无法在php中收到此json对象。我通过回显ING我的Json数据进行检查，可以在“ OnResponse方法”中看到该对象。如果有人可以帮助我解决这个问题，那将是我的荣幸。我欠你很多债。这是我的代码->

Andoird Volley代码->

Json格式为->

private void registerUser() {
    JSONObject postObject = new JSONObject();
    RequestQueue queue =  Volley.newRequestQueue(this);
    JSONObject historyObject = new JSONObject();

    String url ="http://helpinghandbd.org/app/index.php";
    try {
        //historyObject.put("id","1");
        historyObject.put("email","1234");
        historyObject.put("password","1234");
        postObject.put("user",historyObject);
    } catch (JSONException e) {
        e.printStackTrace();
    }

    Log.e("LoginActivityJsonObject",""+postObject);
    JsonObjectRequest objRequest = new JsonObjectRequest(Request.Method.POST, url,postObject,
            new Response.Listener<JSONObject>() {
                @Override
                public void onResponse(JSONObject response) {
                    Log.e("LoginActivity","OnResponse: "+response);
                    Toast.makeText(LoginActivity.this, String.valueOf(response), Toast.LENGTH_LONG).show();
                }
            }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            Log.e("OnError", String.valueOf(error.getMessage()));
        }
    });

    queue.add(objRequest);

}

最后，PHP代码是->

{ 'user':{
           'email':'1234',
           'password':'1234'
        }
 }

我无法在PHP中接收Json对象。预先感谢。

在您的php代码中，更改

$decode = json_decode($data,true);
$email = $decode->user['email'];
$password = $decode->user['passowrd'];

到

$decode = json_decode($data,true);
$email = $decode['user']['email'];
$password = $decode['user']['passowrd'];

使用Volley Library从Android接收PHP服务器中的Json数据POST方法
