解析数据时出错org.json.jsonexception：java.lang.string类型的值< br无法转换为jsonarray

问题描述

我正在尝试在注册页面中注册用户但是收到错误，我已经转换了我需要的所有细节但仍然无效，可能问题来自php代码。插入不起作用。 />


我尝试过：



这是注册活动

公共类注册扩展AppCompatActivity {
 
 EditText name1，etpolicyNumber，etPassword; 
 Button bRegister; 
 
 
 @Override 
 protected void onCreate（Bundle savedInstanceState）{
 super.onCreate（savedInstanceState）; 
 setContentView（R.layout.register）; 
 
 
 name1 =（EditText）findViewById（R.id.name）; 
 etpolicyNumber =（EditText）findViewById（R.id.policy_number1）; 
 etPassword =（EditText）findViewById（R.id.password1）; 
 bRegister =（Button）findViewById（R.id.btnregister）; 
 
 bRegister.setOnClickListener（new View.OnClickListener（）{
 @Override 
 public void onClick（View v）{
 String name = name1.getText（）。 toString（）; 
 String policyNumber = etpolicyNumber.getText（）。toString（）; 
 String password = etPassword.getText（）。toString（）; 
 
 Response.Listener< String> responseListener = new Response.Listener< String>（）{
 @Override 
 public void onResponse（String response）{
 try {
 JSONObject jsonResponse = new JSONObject（response） ; 
 boolean success = jsonResponse.getBoolean（success）; 
 if（success）{
 
 Intent intent = new Intent（Register.this，MainActivity.class）; 
 startActivity（in帐篷）; 
 Toast.makeText（Register.this，Registration Successful，Toast.LENGTH_SHORT）.show（）; 
} else {
 AlertDialog.Builder builder = new AlertDialog.Builder（Register.this）; 
 builder.setMessage（Register Failed）
 .setNegativeButton（Retry，null）
 .create（）
 .show（）; 
 
} 
} catch（JSONException e）{
 e.printStackTrace（）; 
} 
} 
}; 
 
 RegisterRequest registerRequest = new RegisterRequest（name，policyNumber，password，responseListener）; 
 RequestQueue queue = Volley.newRequestQueue（Register.this）; 
 queue.add（registerRequest）; 
} 
}）; 
 
} 
} 

这是RegisterRequest java

 public class RegisterRequest extends StringRequest {
 private static final String REGISTER_REQUEST_URL =http://beigecare.ga/Register.php; 
 private Map< String，String> PARAMS; 
 
 public RegisterRequest（String name，String policyNumber，String password，Response.Listener< String> listener）{
 super（Method.POST，REGISTER_REQUEST_URL，listener，null）; 
 params = new HashMap<>（）; 
 params.put（name，name）; 
 params.put（policyNumber，policyNumber）; 
 params.put（密码，密码）; 
 
 
} 
 @Override 
公共地图< String，String> getParams（）{
 return params; 
} 
} 

这是注册php代码

<？php 
 $ con = mysqli_connect（mysql.hostinger.in，u608965245_user，Engmann1，u608965245_data）; 
 
 $ name = $ _POST [name]; 
 $ policynumber = $ _POST [policyNumber]; 
 $ password = $ _POST [password]; 
 $ statement = mysqli_prepare（$ con，INSERT INTO user（name，policynumber，password）VALUES（？，？，？））; 
 mysqli_stmt_bind_param（$ statement，siss，$ name，$ policynumber，$ password）; 
 mysqli_stmt_execute（$ statement）; 
 
 $ response = array（）; 
 $ response [success] = true; 
 
 
 echo json_encode（$ response）; 
？> 

请帮我纠正错误

解决方案

I am trying to register a user in the registration page but getting error, i have converted every details i need to string but still not working,maybe the problem is from the php code.the insert doesn't work.

What I have tried:

this is the Registration activity

public class Register extends AppCompatActivity {

    EditText name1, etpolicyNumber, etPassword;
    Button bRegister;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.register);


        name1 = (EditText) findViewById(R.id.name);
        etpolicyNumber = (EditText) findViewById(R.id.policy_number1);
        etPassword = (EditText) findViewById(R.id.password1);
        bRegister = (Button) findViewById(R.id.btnregister);

        bRegister.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                String name = name1.getText().toString();
                String policyNumber = etpolicyNumber.getText().toString();
                String password = etPassword.getText().toString();

                Response.Listener<String> responseListener = new Response.Listener<String>() {
                    @Override
                    public void onResponse(String response) {
                        try {
                            JSONObject jsonResponse = new JSONObject(response);
                            boolean success = jsonResponse.getBoolean("success");
                            if (success) {

                                Intent intent = new Intent(Register.this, MainActivity.class);
                                startActivity(intent);
                                Toast.makeText(Register.this, "Registration Successful", Toast.LENGTH_SHORT).show();
                            } else {
                                AlertDialog.Builder builder = new AlertDialog.Builder(Register.this);
                                builder.setMessage("Register Failed")
                                        .setNegativeButton("Retry", null)
                                        .create()
                                        .show();

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

                RegisterRequest registerRequest = new RegisterRequest(name, policyNumber, password, responseListener);
                RequestQueue queue = Volley.newRequestQueue(Register.this);
                queue.add(registerRequest);
            }
        });

    }
}

this is the RegisterRequest java

public class RegisterRequest extends StringRequest {
    private static final String REGISTER_REQUEST_URL = "http://beigecare.ga/Register.php";
    private Map<String, String> params;

    public RegisterRequest(String name, String policyNumber, String password, Response.Listener<String> listener){
        super(Method.POST, REGISTER_REQUEST_URL, listener, null);
        params = new HashMap<>();
        params.put("name", name);
        params.put("policyNumber", policyNumber);
        params.put("password", password);


    }
    @Override
    public Map<String, String> getParams(){
        return params;
    }
}

this is the register php code

<?php
    $con = mysqli_connect("mysql.hostinger.in", "u608965245_user", "Engmann1", "u608965245_data");

    $name = $_POST["name"];
    $policynumber = $_POST["policyNumber"];
    $password = $_POST["password"];
    $statement = mysqli_prepare($con, "INSERT INTO user (name, policynumber, password) VALUES (?, ?, ?)");
    mysqli_stmt_bind_param($statement, "siss", $name, $policynumber, $password);
    mysqli_stmt_execute($statement);

    $response = array();
    $response["success"] = true;


    echo json_encode($response);
?>

Please help me correctn it
