將數據發布到Mysql時，具有Retrofit 2的應用程序崩潰

[英]An app with Retrofit 2 crashes while posting data to Mysql

問題描述

我正在開發一個Android應用程序，需要使用php將數據發布到mysql db並獲取數據。 現在，我正在嘗試向用戶注冊應用程序。 我創建了2個php類Connection和insertUser 。 使用Postman，我可以成功地將數據插入數據庫。 但是當我嘗試使用物理電話時，它崩潰了。 我的代碼構建沒有錯誤，直到我按SignUp按鈕，它才能正常工作。 我看不到我在哪里犯錯。 請幫忙。

我添加了我的依賴項。 

    compile 'com.squareup.retrofit2:retrofit:2.3.0'
    compile 'com.squareup.retrofit2:converter-gson:2.3.0'
    compile 'com.squareup.okhttp:okhttp:2.0.0'

用於連接我的本地XAMPP Phpmyadmin的Connection.php。 

<?php

    class Connection{
        function getConnection(){
            $host       = "localhost";
            $username   = "root";
            $password   = "root";
            $dbname     = "activityplanner_db";
            try{
                $conn    = new PDO("mysql:host=$host;dbname=$dbname", $username, $password);
                $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
                return $conn;
            }catch (PDOException $e){
                echo "ERROR CONNECTIONF : " . $e->getMessage();
            }
        }
    }

    ?>

insertUser.php用於將用戶信息插入數據庫。 

<?php

require_once('Connection.php');
class insertUser{
    function startInsertUser(){
        $connection = new Connection();
        $conn = $connection->getConnection();
        //array for json response
        $response = array();
        $Lastname = $_POST['LastName'];
        $Firstname = $_POST['FirstName'];
        $Email = $_POST['User_Email'];
        $Mobilephone = $_POST['MobilePhone'];
        $Ssn = $_POST['SSN'];
        $Password = $_POST['User_Password'];
        $City = $_POST['User_City'];
        $JobTittle = $_POST['User_Job'];
        $BirthDate = $_POST['User_BirthDate'];
        $Gender = $_POST['Gender'];

        if($Lastname == '' || $Firstname == '' || $Email == '' || $Mobilephone == '' || $Ssn == '' || $Password == '' || $City == '' || $JobTittle == '' || 
        $BirthDate == ''){
        echo 'All fields required';
    }
        try{
            if(isset($Email) && isset($Ssn)){
                $sqlInsert = "INSERT INTO user (LastName, FirstName, User_Email, MobilePhone, SSN, User_Password,
                 User_City, User_Job, User_BirthDate, Gender) VALUES ('$Lastname', '$Firstname', '$Email', '$Mobilephone', '$Ssn', '$Password', 
                    '$City','$JobTittle', '$BirthDate', '$Gender')";
                $conn->exec($sqlInsert);
            }
        }catch (PDOException $e){
            echo "Error while inserting ".$e->getMessage();
        }
        //cek is the row was inserted or not
        if($sqlInsert){
            //success inserted
            $response["success"] = 1;
            $response["message"] = "User successful inserted!";
            echo json_encode($response);
        }else{
            //failed inserted
            $response["success"] = 0;
            $response["message"] = "Failed while insert data";
            echo json_encode($response);
        }
    }
}
$insert = new insertUser();
$insert->startInsertUser();;
?>

LoggingInterceptors .java以查看顯示數據的進程的輸出。 如果有錯誤，則此類文件知道錯誤的原因。 Ť 

public class LoggingInterceptors implements Interceptor{

    @Override
    public Response intercept(Chain chain) throws IOException{
        Request request = chain.request();
        long t1 = System.nanoTime();
        String requestLog = String.format("Sending request %s on %s%n%s",
                request.url(), chain.connection(), request.headers());

        if (request.method().compareToIgnoreCase("post") == 0){
            requestLog = "\n" + requestLog + "\n" + bodyToString(request);
        }

        Log.d("TAG", "request" + "\n" + requestLog);
        Response response = chain.proceed(request);

        long t2 = System.nanoTime();
        String responseLog = String.format("Received response for %s in %.1fms%n%s",
                response.request().url(), (t2 - t1) / 1e6d, response.headers());

        String bodyString = response.body().string();
        Log.d("TAG", "response" + "\n" + responseLog + "\n" + bodyString);

        return response.newBuilder()
                .body(ResponseBody.create(response.body().contentType(), bodyString))
                .build();
    }

    public static String bodyToString(final Request request){
        try{
            final Request copy = request.newBuilder().build();
            final Buffer buffer = new Buffer();
            copy.body().writeTo(buffer);

            return buffer.readUtf8();
        }catch (final IOException e){
            return "did not work";
        }
    }
}

我的URLs.java Api Client for Retrofit Client 。 

public class URLs {

    public static final String URL = "http://192.168.43.172/activityplanner_php/";

//當我將PC連接到手機的熱點時，這是我的ipv4 ip。 公共靜態翻新改造= null; 

    public static Retrofit getClient(){
        if (retrofit==null){
            OkHttpClient client = new OkHttpClient.Builder()
                    .addInterceptor(new LoggingInterceptors())
                    .build();
            retrofit = new Retrofit.Builder()
                    .baseUrl(URL)
                    .client(client)
                    .addConverterFactory(GsonConverterFactory.create())
                    .build();
        }
        return retrofit;
    }

}

還有我的RegisterApi接口 

public interface RegisterAPI {

    @FormUrlEncoded
    @POST("/activityplanner_php/insertUser.php")
    Call<User> insertUser(@Field("LastName") String LastName, @Field("FirstName") String FirstName,
                          @Field("User_Email") String User_Email, @Field("MobilePhone") long MobilePhone,
                          @Field("SSN") String SSN, @Field("User_Password") String User_Password,
                          @Field("User_City") String User_City, @Field("User_Job") String User_Job,
                          @Field("User_BirthDate") Date User_BirthDate, @Field("Gender") String Gender);
}

我的用戶響應模型。 

public class User {

    @SerializedName("success")
    private int status;
    @SerializedName("message")
    private String message;

    public User(int status, String message) {
        this.status = status;
        this.message = message;
    }

    public User() {
    }

    public int getStatus() {
        return status;
    }

    public void setStatus(int status) {
        this.status = status;
    }

    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }    
}

還有我的SignUpActivity。 

public class SignUpActivity extends AppCompatActivity {

    EditText etLastName, etFirstName, etEmail, etMobilePhone, etSsn, etPassword, etCity, etJob, etBirthDate;
    RadioGroup rgGender;
    Spinner spUserType;
    ProgressDialog progressDialog;


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

        Button btnSignUp = (Button) findViewById(R.id.bSignUp);
        etBirthDate = (EditText) findViewById(R.id.etBirthDate);
        etLastName = (EditText) findViewById(R.id.etLastName);

        etPassword = (EditText) findViewById(R.id.etPassword);
        etCity = (EditText) findViewById(R.id.etCity);
        etJob = (EditText) findViewById(R.id.etJob);
        rgGender = (RadioGroup) findViewById(R.id.rgGender);
        spUserType = (Spinner) findViewById(R.id.spUserRole);

        btnSignUp.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                insertUser();
            }
        });


    }
    /*public void GoToLoginActivity(View v) {
        insertUser();
        Intent intent = new Intent(this, LoginActivity.class);
        startActivity(intent);
    }*/


    private void insertUser(){
        progressDialog.show();

        String firstName = etFirstName.getText().toString();
        String lastName = etLastName.getText().toString();
        String u_Email = etEmail.getText().toString();

        int radioButtonId = rgGender.getCheckedRadioButtonId();
        View radioButton = rgGender.findViewById(radioButtonId);
        int idx = rgGender.indexOfChild(radioButton);
        RadioButton rbGender = (RadioButton)rgGender.getChildAt(idx);

        String gender = rbGender.getText().toString();
        Long mobilePhone =Long.parseLong(etMobilePhone.getText().toString());
        String ssn = etSsn.getText().toString();
        String u_City = etCity.getText().toString();
        Date birthDate =Date.valueOf(etBirthDate.getText().toString());
        String u_Job = etJob.getText().toString();
        String password = etPassword.getText().toString();

        insertData(firstName,lastName,u_Email,gender,mobilePhone,ssn,u_City,birthDate,u_Job,password);
    }
        private void insertData(String firstName, String lastName, String u_Email, String gender,
                Long mobilePhone, String ssn, String u_City, Date birthDate, String u_Job, String password){

            RegisterAPI registerAPI = URLs.getClient().create(RegisterAPI.class);
            Call<User> call = registerAPI.insertUser(firstName, lastName, u_Email, mobilePhone, ssn, password,
                    u_City, u_Job, birthDate, gender);
            call.enqueue(new Callback<User>() {
                @Override
                public void onResponse(Call<User> call, Response<User> response) {
                    User user =response.body();

                    if(user.getStatus()==1){
                        Toast.makeText(SignUpActivity.this, response.body().getMessage(), Toast.LENGTH_SHORT).show();
                        progressDialog.dismiss();
                    }else{
                        Toast.makeText(SignUpActivity.this, response.body().getMessage(), Toast.LENGTH_SHORT).show();
                        progressDialog.dismiss();
                    }
                }

                @Override

我看不到您在此處初始化進度對話框。 我猜這是您在調用show（）之前未初始化進度對話框的錯誤 

ProgressDialog progressDialog;

 @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_sign_up);
        progressDialog = new ProgressDialog(this);
        ...............

}
