NetworkUtility.shouldRetryException：( *URL* ) 出现意外响应代码 500

Question

我正在尝试使用 POST 方法登录我的 Android 应用程序。我的 Logcat 中不断出现该错误。这是我的 sign_in.java 代码，

      requestQueue = Volley.newRequestQueue(this);

        btnSignIn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                sharedPreferences = getSharedPreferences(SHARED_PREF_NAME,MODE_PRIVATE);


                SharedPreferences.Editor editor = sharedPreferences.edit();
                editor.putString(KEY_USERNAME,username.getText().toString());
                editor.putString(KEY_PASSWORD,password.getText().toString());
                editor.apply();

                if(KEY_USERNAME != null & KEY_PASSWORD != null) {

                    Intent intent = new Intent(sign_in.this, menu.class);
                    startActivity(intent);
                }


                request = new StringRequest(Request.Method.POST, URL, new Response.Listener<String>() {
                    @Override
                    public void onResponse(String response) {
                        try {
                            JSONObject jsonObject = new JSONObject(response);
                            if(jsonObject.names().get(0).equals("success")){
                                Toast.makeText(getApplicationContext(),"SUCCESS "+jsonObject.getString("success"),Toast.LENGTH_SHORT).show();
                                startActivity(new Intent(getApplicationContext(),menu.class));
                            }else {
                                Toast.makeText(getApplicationContext(), "Error" +jsonObject.getString("error"), Toast.LENGTH_SHORT).show();

                            }

                        } catch (JSONException e) {
                            e.printStackTrace();
                        }


                    }
                }, new Response.ErrorListener() {
                    @Override
                    public void onErrorResponse(VolleyError error) {

                    }
                            }){

                    @Override
                    protected Map<String, String> getParams() throws AuthFailureError {
                        HashMap<String,String> hashMap = new HashMap<String, String>();
                        hashMap.put("username",username.getText().toString());
                        hashMap.put("password",password.getText().toString());

                        return hashMap;
                    }
                };

                requestQueue.add(request);
            }
        });
    }
}

我之前在 localhost 上尝试过，它有效，但是当我通过 Web 服务器托管它时，登录时一切都混乱了。

帮助我，这就是我的 Logcat 中显示的内容。

Answer 1

步骤 1-

在 app/src/main/res/xml/ 中使用相应的 network_security_config.xml：

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <base-config cleartextTrafficPermitted="true" />
</network-security-config>

步骤 2-
在 AndroidManifest.xml 的

<application
....
    android:usesCleartextTraffic="true"
 android:networkSecurityConfig="@xml/network_security_config"
.....>
