在将数据发布到Mysql时，Retrofit 2的应用程序崩溃了

标签： java android retrofit2

我正在开发一个Android应用程序，需要使用mysql向php db发布和获取数据。现在我正在尝试将用户注册到应用程序。我创建了2个php类连接和 insertUser 。使用Postman，我可以成功地将数据插入数据库。但是，当我尝试使用手机时，它会崩溃。我的代码构建没有错误，直到我按SignUp按钮它工作正常。我无法看到我犯错误的地方。请帮忙。

我添加了我的依赖项。

    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'

Connection.php用于连接我的localhost XAMPP Phpmyadmin。

<?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，用于将用户信息插入数据库。

<?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查看进程显示数据的输出。如果有错误，则此类文件知道错误的原因。 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客户Retrofit Client。

public class URLs {

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

//当我将电脑连接到手机的热点时，这是我的ipv4 ip。         public static Retrofit retrofit = 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;
    }

}

我的RegisterApi界面

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_BirthDate") Date User_BirthDate, @Field("Gender") String Gender);
}

我的用户响应模型。

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;
    }    
}

我没有看到你在这里初始化进度对话框。我想这是在调用 show（）

之前没有初始化进度对话框的错误 
ProgressDialog progressDialog;

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

}
