Volley使用URL编码参数进行POST请求时未传递。

Volley POST with URL ENCODED parameters not being passed

问题

我需要进行一个带有url编码参数的HTTPS POST 请求,如下所示:

> https://logintest.moveon.pro/?rest_route=/simple-jwt-login/v1/auth&email=Email&password=Password

并且返回一个JSON,如下所示:

{"success":false,"data":{"message":"Wrong user credentials.","errorCode":48}}

我正在使用Android Studio上的Volley库。

我已经完成的工作:

  1. 我在PostMan上尝试了整个过程。以下是我的结论:

    • POST 请求有效,GET 请求无效。
    • 需要参数。
    • 请求头中没有任何内容(除了“自动生成”的内容)Postman的请求头
    • 请求体中没有任何内容[Postman的请求体][2]。
    • 即使使用错误的凭据,也会发送JSON响应。只要参数正确,响应的内容就会改变。
    • 我尝试了HTTP和HTTPS两种方式,这两种方式在这里都可以正常工作[HTTPS也一样正常工作][3]。
  2. 我在APP的build.gradle中安装了Volley库依赖[build.gradle中的Volley依赖][4]。

  3. 在我的Manifest.xml中授权了Internet和Network State[manifest.xml中的INTERNET和NETWORK STATE][5]。

  4. 创建了一个非常基本的登录界面作为主要活动。

  5. 单击按钮后,将我进行的测试。

这里是我执行的3个测试:

a. 使用StringRequest(是的,我想要一个POST请求,但不需要在请求体中添加任何内容,我认为保持简单可能是一个好主意)。我在这里进行了大量的测试,与下一个主题JsonObjectRequest一样。

b. 使用JsonObjectRequest(对这个做了很多尝试!我认为我真的尽力了,尝试了StackOverflow和其他地方找到的所有方法)。除其他事项外,尝试覆盖BodyContent、Headers、Body等。

c. 使用一个新的“帮助”类,该类扩展了Request<JSONObject>,正如我在[这里][6]所读到的。

我的问题是:

我找不到一种方法来将参数传递给POST的URL...在调试时,我得到的是Volley的“mUrl”作为基本URL(https://logintest.moveon.pro/),而不是带有添加参数的URL(https://logintest.moveon.pro/?rest_route=/simple-jwt-login/v1/auth&email=Email&password=Password)。

以下是我的代码...
我在这里使用了一个愚蠢的“if”语句,以测试不同的方法,不要责怪我太多;-)...
并且想要发送的参数中存在很多冗余。

I need to make a HTTPS **POST** with urlencoded parameters like this :

&gt; https://logintest.moveon.pro/?rest_route=/simple-jwt-login/v1/auth&amp;email=Email&amp;password=Password

And get in return a JSON like this :

    {&quot;success&quot;:false,&quot;data&quot;:{&quot;message&quot;:&quot;Wrong user credentials.&quot;,&quot;errorCode&quot;:48}}

I am using Volley library on Android Studio.

**What I have done :**

 1. I have tried the complete process on PostMan. Here are the conclusion :
- POST works, GET does not.
- Parameters are needed
- There is NOTHING in header (on request, except the &quot;auto-generated&quot; ones)[Postman of Header][1]
- There is NOTHING in body (on request)[Postman of Body][2]
- Checked that even with incorrect credentials, a JSON answer is sent. Just the content of the answer will change if the parameters are correct.
- I tried with both, HTTP &amp; HTTPS, both work the same here.[HTTPS working just as fine][3]

 2. Installed Volley in the APP build.gradle
[build.gradle Volley dependenciy][4]

 3. Authorized the Internet &amp; Network State in my Manifest.xml
[manifest.xml INTERNET &amp; NETWROK STATE][5]

 4. Did a very basic login Screen as main activity 

 5. When clicking, direct me on my TESTs I&#39;ve done.

Here are my 3 tests performed :

a. With StringRequest (Yes, I want a POST, but don&#39;t need anything in the request body, I thought it could be an idea to go simple). I did a great deal of testing here, same as with the next subject, the JsonObjectRequest.

b. With a JsonObjectRequest (Did soooooo many tries with this one ! I think I really tried all I could find on StackOverflow... and others...).
Among other things trying to override BodyContent, Headers, Body, etc...

c. With a new &quot;helping&quot; class which extends the Request&lt;JSONObject&gt;. as I read [here][6].

**What is my problem :**

I can&#39;t find a way to pass my parameters to the POST url... When debugging I get the &quot;mUrl&quot; of Volley as the basic URL (https://logintest.moveon.pro/) and not the one with added parameters (https://logintest.moveon.pro/?rest_route=/simple-jwt-login/v1/auth&amp;email=Email&amp;password=Password).

Here is my code...
I used a stupid &quot;if&quot; in order to test the different approaches, don&#39;t blame me too hard on this ;-)...
And there is a LOT of redundancy in the parameters wanting to be sent.

                            }

                                new Response.ErrorListener() {

                                    public void onErrorResponse(VolleyError error) {
                                        usernameEditText.setText(&quot;That didn&#39;t work!&quot;);
                                        Log.e(&quot;HttpClient&quot;, &quot;error: &quot; + error.toString());
                                    }

                    }
                }
            });
    
        }
    
    }

Also here is the &quot;helper&quot; class I took form the post already mentioned :

你可以这样发送一个x-www-form-urlencoded请求
- 请求头Content-Type: application/x-www-form-urlencoded
- 请求体rest_route=/simple-jwt-login/v1/auth&amp;password=&lt;YOUR_PASSWORD&gt;&amp;email=&lt;YOUR_EMAIL&gt;。(用正确的凭据替换占位符)。

你可以参考这个链接https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods/POST

让我知道你的更新 =)

<details>
<summary>英文:</summary>

you can send a x-www-form-urlencoded request in this way: 
- request header: Content-Type: application/x-www-form-urlencoded
- request body: rest_route=/simple-jwt-login/v1/auth&amp;password=&lt;YOUR_PASSWORD&gt;&amp;email=&lt;YOUR_EMAIL&gt;. (replace the placeholder by the correct credentials).

这是我的工作代码

问题出现在API中即使语法正确它仍然返回400代码

当我通过POSTMAN发现这个问题后我寻找了一种仍然可以从我的POST请求中获取响应体的方法使用Volley错误返回

我找到了这个帖子[这里][1]我将它添加到我的解决方案中简化了它到最大限度这是结果

最好的问候,愿您编程愉快!!!

英文:

so here is my working code.

The problem was lying into the API which was returning 400 code even though the syntax was correct.

When I found this out thanks to POSTMAN, I looked for a way to still get the body answer from my POST, using Volley Error return.

I found this post here which I added to my solution '0', simplified it at maximum, and here is the result :
package com.example.logintest;

import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ProgressBar;
import com.android.volley.NetworkResponse;
import com.android.volley.Request;
import com.android.volley.RequestQueue;
import com.android.volley.Response;
import com.android.volley.ServerError;
import com.android.volley.VolleyError;
import com.android.volley.toolbox.HttpHeaderParser;
import com.android.volley.toolbox.StringRequest;
import com.android.volley.toolbox.Volley;
import org.json.JSONException;
import org.json.JSONObject;
import java.io.UnsupportedEncodingException;
import java.util.HashMap;
import java.util.Map;
public class MainActivity extends AppCompatActivity {
/**
* Logcat tag
*/
private static final String TAG = MainActivity.class.getSimpleName();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final EditText usernameEditText = findViewById(R.id.username);
final EditText passwordEditText = findViewById(R.id.password);
final Button loginButton = findViewById(R.id.login);
final ProgressBar loadingProgressBar = findViewById(R.id.loading);
loginButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// Instantiate the RequestQueue.
RequestQueue queue = Volley.newRequestQueue(getApplicationContext());
String url = &quot;https://logintest.moveon.pro/&quot;;
// Request a string response from the provided URL.
StringRequest sr = new StringRequest(Request.Method.POST, url,
new Response.Listener&lt;String&gt;() {
@Override
public void onResponse(String response) {
Log.e(&quot;HttpClient&quot;, &quot;success! response: &quot; + response.toString());
// Display the first 500 characters of the response string.
usernameEditText.setText(&quot;Response is: &quot; + response.toString().substring(0, 500));
}
},
new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
usernameEditText.setText(&quot;That didn&#39;t work!&quot;);
// As of f605da3 the following should work
NetworkResponse response = error.networkResponse;
if (error instanceof ServerError &amp;&amp; response != null) {
try {
String res = new String(response.data,
HttpHeaderParser.parseCharset(response.headers, &quot;utf-8&quot;));
// Now you can use any deserializer to make sense of data
JSONObject obj = new JSONObject(res);
usernameEditText.setText(usernameEditText.getText() + res);
} catch (UnsupportedEncodingException e1) {
// Couldn&#39;t properly decode data to string
e1.printStackTrace();
} catch (JSONException e2) {
// returned data is not JSONObject?
e2.printStackTrace();
}
}
Log.e(&quot;HttpClient&quot;, &quot;error: &quot; + error.toString());
}
}) {
@Override
protected Map&lt;String, String&gt; getParams() {
Map&lt;String, String&gt; params = new HashMap&lt;String, String&gt;();
params.put(&quot;rest_route&quot;, &quot;/simple-jwt-login/v1/auth&quot;);
params.put(&quot;email&quot;, &quot;dummy@gmail.com&quot;);
params.put(&quot;password&quot;, &quot;935jIDan^4S@$rAFLw4w@!$Z&quot;);
return params;
}
};
// Add the request to the RequestQueue.
queue.add(sr);
}
});
}
}

Hope this will help someone...

Best regards, and happy coding !!!
