Facebook检测到Believer没有使用安全连接来传输信息

如何解决Facebook检测到Believer没有使用安全连接来传输信息

好吧，我尝试添加登录并使用Facebook功能进行注册，当我单击Facebook登录时，它带我到Facebook，但显示诸如以下错误 Facebook已发现Believer没有使用安全连接来传输信息。 在Believer更新其安全设置之前，您将无法使用Facebook登录。

我为社交应用添加的那些行使用了注释。这段代码来自我的project / settings.py

import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.util.HashMap;
import java.util.Scanner;

@SuppressWarnings("unchecked") //was the only way to stop the error: "Type safety: Unchecked cast from Object to HashMap<String,Song>" from happening

public class Main {
    public static void main(String[] args) throws FileNotFoundException,IOException,ClassNotFoundException {
        // Map of songs
        HashMap<String,Song> playList = new HashMap<String,Song>();

        // getting file name where it is stored
        Scanner input = new Scanner(System.in);
        System.out.print("Enter the file name you stored/will store your playlist in: ");
        String fileName = input.nextLine();
        input.close();

        File file = new File(fileName);
        
        ObjectOutputStream out = new ObjectOutputStream(new BufferedOutputStream(new FileOutputStream(file))); //using output streams to find the file requested by user

        if (file.length() == 0) {
            out.writeObject(playList);
            //System.out.println("Wrote playlist"); //debug
        } //sees if there is nothing in the file,and if there is nothing,writes a blank HashMap to it

        ObjectInputStream in = new ObjectInputStream(new BufferedInputStream(new FileInputStream(file))); //This is where the EOFException is taking place. In the if statement above,it tests if the file is empty. Since playlist.dat is empty,it will attempt to write an empty HashMap playlist to the file,but since there is an EOFException and playlist.dat is empty,it is clearly not doing this.
        
        playList = (HashMap<String,Song>) in.readObject();
        System.out.println("Opening playlist at " + fileName + "."); //debug
        in.close();
