php - 无法在 Android 中使用 PHP 脚本插入 MySQL

Question

我正在尝试使用 Volley 库的 php 脚本将 firebase token_key 插入到 mysql 中，但无法实现它。我面临“AuthFailureError”异常。

我知道我犯了一些错误，但无法弄清楚。我在此处附上代码 fragment ，请给我一些建议:

初始化文件

<?php

$host = "localhost";
$db_user = "root";
$db_password = "*****";
$db_name = "fcmdb";

$con = mysqli_connect($host,$db_user,$db_password,$db_name);
if($con)
echo "Connection Success...";
else
echo "Connection Failure...";

?>

fcm_insert.php

<?php

require "init.php";
$fcm_token ='';
$fcm_token = $_POST["key_token"];
$sql = "insert into fcm_info values('".$fcm_token."');";
mysqli_query($con,$sql);
mysqli_close($con);

?>

主 Activity .java

public class MainActivity extends AppCompatActivity {
private Button btnClick;
String app_server_url="http://192.168.0.106:8079/fcmtest/fcm_insert.php";
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        btnClick=(Button)findViewById(R.id.button);

        btnClick.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                SharedPreferences sharedPreferences=getApplicationContext().getSharedPreferences(getString(R.string.FCM_PREF), Context.MODE_PRIVATE);
                final String token=sharedPreferences.getString(getString(R.string.FCM_TOKEN),"");

                StringRequest stringRequest=new StringRequest(Request.Method.POST, app_server_url, new Response.Listener<String>() {
                    @Override
                    public void onResponse(String response) {
                        Log.i("Error",response.toString());
                    }
                }, new Response.ErrorListener() {
                    @Override
                    public void onErrorResponse(VolleyError error) {
                        Log.i("Error",error.toString());
                    }
                })

                {
                    @Override
                    protected Map<String, String> getParams() throws AuthFailureError {
                        Map<String,String> params=new HashMap<String, String>();
                        params.put("key_token",token);

                        return params;
                    }
                };
                MySingleton.getMySingleton(MainActivity.this).addToRequestQueue(stringRequest);
            }
        });
    }
}
