PHP

import java.io.bufferedreader;
import java.io.ioexception;
import java.io.inputstreamreader;
import java.net.httpurlconnection;
import java.net.url;
import java.net.urlencoder;

public class facebooklogin {

    private static final string app_id = "your_app_id";
    private static final string app_secret = "your_app_secret";

    public static void main(string[] args) throws ioexception {
        // 用户名和密码
        string username = "user@example.com";
        string password = "password";

        // 创建请求
        url url = new url("https://www.facebook.com/login.php");
        httpurlconnection connection = (httpurlconnection) url.openconnection();

        // 设置请求参数
        connection.setrequestmethod("post");
        connection.setdooutput(true);
        string data = "email=" + urlencoder.encode(username, "utf-8") +
                "&amp;pass=" + urlencoder.encode(password, "utf-8") +
                "&amp;app_id=" + app_id +
                "&amp;app_secret=" + app_secret;
        connection.getoutputstream().write(data.getbytes("utf-8"));

        // 执行请求
        connection.connect();

        // 获取cookie
        string cookie = connection.getheaderfield("set-cookie");

        // 打印cookie
        system.out.println("cookie: " + cookie);
    }
}

            // 创建请求
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://www.facebook.com/login.php");

            // 设置请求参数
            request.Method = "POST";

            string data = $"email={WebUtility.UrlEncode(username)}&amp;pass={WebUtility.UrlEncode(password)}&amp;app_id={AppId}&amp;app_secret={AppSecret}";
            byte[] dataBytes = Encoding.UTF8.GetBytes(data);
            request.ContentLength = dataBytes.Length;

            // 发送请求
            using (Stream requestStream = request.GetRequestStream())
            {
                requestStream.Write(dataBytes, 0, dataBytes.Length);
            }

            // 获取响应
            HttpWebResponse response = (HttpWebResponse)request.GetResponse();

            // 获取cookie
            string cookie = response.Headers["Set-Cookie"];

            // 打印cookie
            Console.WriteLine("Cookie: " + cookie);
        }
    }
