thinkphp5模拟post请求_Thinkphp5.1模拟登录并提交form表单
最近项目需要，要远程登录别人的系统，并且在对方的系统中提交表单，所以写了一个类。
namespace app\api\controller;
use think\Db;
use think\Controller;
use think\facade\Env;
use think\facade\Request;
class Offline extends Controller

public $baseUrl = 'http://localhost:8080';
//登录错误返回的链接
public $loginErrorUrl = '/login';
//登录验证
public $loginUrl = '/check';
//登录成功跳转

//提交表单
public $orderUrl = '/save';
//提交表单返回页面URL
public $formUrl = '/proposal';
//下载URL
public $downloadUrl = '/downloads';
//记录登录返回的cookie
public $cookieFile;
//日志
public $logFile;

$content = curl_exec($ch);

}
}
这里的返回值基本都是html内容所以我这边是判断的返回值里的URL是不是匹配，可以根据需要调整。
