php - curl远程登录问题

Question

我想远程登录到我的第二个网站，但我遇到了一些问题，因为操作文件是 /user/login.htm 并且表单位于 /user/index.htm

当我尝试在我的第一个网站上发布帖子时，我收到错误消息，提示用户名和密码无效，但我检查了几次，一切正常……帖子是这样的：

continueTo=%2Fuser%2Findex.htm&login=&changeLogInPermanentlyPref=true&email=email%40email.com&password=TESTPASS&submit=&logInPermanently=on&_sourcePage=htYSMjoK0IATah86FF3yMT1zDYzaGsbkGTP5awTC0hykcXEpm9ztqjXVz-aUblAsXV9ykLXP1mm4yo_0TuIk1cjwytYy9KBr&__fp=NhVgRkYa2DMUOPQzpwoBNVSbbb9ZJWU7T8w3OeZ9n2BhRFuQKOPeOQ5rYfieNa75&__at=1584900220._Ai-iNOACLcgaLBOUPwPa551GFQRuWOoDqvLmWby2bU.AXG1Vdh-Vj4V25wzYgcpk3G_HvAZ

脚本是这样的：

    <?php
session_start();
error_reporting(-1);

    $browser = $_SERVER['HTTP_USER_AGENT'];
    $ip = getenv("REMOTE_ADDR");

    $curl = curl_init();



    curl_setopt($curl, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']); //set user agent
    curl_setopt($curl, CURLOPT_URL, BASE_URL . $_SERVER['REQUEST_URI']);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
