  我已经让它好好享受了一段时间，但后来再次重访 . 由于这个问题定期查看 . 这最终是我最终使用的对我有用的东西 .

  define("DOC_ROOT","/path/to/html");
  //username and password of account
  $username = trim($values["email"]);
  $password = trim($values["password"]);
  
  //set the directory for the cookie using defined document root var
  $path = DOC_ROOT."/ctemp";
  //build a unique path with every request to store. the info per user with custom func. I used this function to build unique paths based on member ID, that was for my use case. It can be a regular dir.
  //$path = build_unique_path($path); // this was for my use case
  
  //login form action url
  $url="https://www.example.com/login/action"; 
  $postinfo = "email=".$username."&password=".$password;
  
  $cookie_file_path = $path."/cookie.txt";
  
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_HEADER, false);
  curl_setopt($ch, CURLOPT_NOBODY, false);
  curl_setopt($ch, CURLOPT_URL, $url);
  curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
  
  curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file_path);
  //set the cookie the site has for certain features, this is optional
  curl_setopt($ch, CURLOPT_COOKIE, "cookiename=0");
  curl_setopt($ch, CURLOPT_USERAGENT,
      "Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7.12) Gecko/20050915 Firefox/1.0.7");
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch, CURLOPT_REFERER, $_SERVER['REQUEST_URI']);
  curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
  curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0);
  
  curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
  curl_setopt($ch, CURLOPT_POST, 1);
  curl_setopt($ch, CURLOPT_POSTFIELDS, $postinfo);
  curl_exec($ch);
  
  //page with the content I want to grab
  curl_setopt($ch, CURLOPT_URL, "http://www.example.com/page/");
  //do stuff with the info with DomDocument() etc
  $html = curl_exec($ch);
  curl_close($ch);
  

  Update: This code was never meant to be a copy and paste. It was to show how I used it for my specific use case. You should adapt it to your code as needed. Such as directories, vars etc

  我有同样的问题，我找到了这个答案on this website .

  我稍微改了一下（最后一行的curl_close）

  $username = 'myuser';
  $password = 'mypass';
  $loginUrl = 'http://www.example.com/login/';
  
  //init curl
  $ch = curl_init();
  
  //Set the URL to work with
  curl_setopt($ch, CURLOPT_URL, $loginUrl);
  
  // ENABLE HTTP POST
  curl_setopt($ch, CURLOPT_POST, 1);
  
  //Set the post parameters
  curl_setopt($ch, CURLOPT_POSTFIELDS, 'user='.$username.'&pass='.$password);
  
  //Handle cookies for the login
  curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie.txt');
  
  //Setting CURLOPT_RETURNTRANSFER variable to 1 will force cURL
  //not to print out the results of its query.
  //Instead, it will return the results as a string return value
  //from curl_exec() instead of the usual true/false.
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  
  //execute the request (the login)
  $store = curl_exec($ch);
  
  //the login is now done and you can continue to get the
  //protected content.
  
  //set the URL to the protected file
  curl_setopt($ch, CURLOPT_URL, 'http://www.example.com/protected/download.zip');
  
  //execute the request
  $content = curl_exec($ch);
  
  curl_close($ch);
  
  //save the data to disk
  file_put_contents('~/download.zip', $content);
  

  我想这就是你要找的东西 . 我是对的吗？

  查看登录页面的来源 . 查找 form HTML标记 . 在该标记内的内容看起来像 action= 将该值用作 $url ，而不是表单本身的URL .

  此外，当您在那里时，请验证输入框是否已列为您列出的内容 .

  例如，基本登录表单看起来类似于：

  <form method='post' action='postlogin.php'>
      Email Address: <input type='text' name='email'>
      Password: <input type='password' name='password'>
  </form>
  

  使用上面的表单作为示例，将 $url 的值更改为：

  $url="http://www.myremotesite.com/postlogin.php";
  

  验证 $postdata 中列出的值：

  $postdata = "email=".$username."&password=".$password;
  

  它应该工作得很好 .

  这就是我在ImpressPages中解决这个问题的方法：

  //initial request with login data
  
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_URL, 'http://www.example.com/login.php');
  curl_setopt($ch, CURLOPT_USERAGENT,'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Ubuntu Chromium/32.0.1700.107 Chrome/32.0.1700.107 Safari/537.36');
  curl_setopt($ch, CURLOPT_POST, true);
  curl_setopt($ch, CURLOPT_POSTFIELDS, "username=XXXXX&password=XXXXX");
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
  curl_setopt($ch, CURLOPT_COOKIESESSION, true);
  curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie-name');  //could be empty, but cause problems on some hosts
  curl_setopt($ch, CURLOPT_COOKIEFILE, '/var/www/ip4.x/file/tmp');  //could be empty, but cause problems on some hosts
  $answer = curl_exec($ch);
  if (curl_error($ch)) {
      echo curl_error($ch);
  }
  
  //another request preserving the session
  
  curl_setopt($ch, CURLOPT_URL, 'http://www.example.com/profile');
  curl_setopt($ch, CURLOPT_POST, false);
  curl_setopt($ch, CURLOPT_POSTFIELDS, "");
  $answer = curl_exec($ch);
  if (curl_error($ch)) {
      echo curl_error($ch);
  }

  巴拿马杰克示例对我不起作用 - 给出致命错误：调用未定义的函数build_unique_path（） . 我使用了这段代码 - （更简单 - 我的意见）：

  // options $login_email = 'alabala@gmail.com'; $login_pass = 'alabala4807'; $cookie_file_path = "/tmp/cookies.txt"; $LOGINURL = "http://alabala.com/index.php?route=account/login"; $agent = "Nokia-Communicator-WWW-Browser/2.0 (Geos 3.0 Nokia-9000i)"; // begin script $ch = curl_init(); // extra headers $headers[] = "Accept: */*"; $headers[] = "Connection: Keep-Alive"; // basic curl options for all requests curl_setopt($ch, CURLOPT_HTTPHEADER,  $headers); curl_setopt($ch, CURLOPT_HEADER,  0); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);         curl_setopt($ch, CURLOPT_USERAGENT, $agent); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file_path); curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file_path); // set first URL curl_setopt($ch, CURLOPT_URL, $LOGINURL); // execute session to get cookies and required form inputs $content = curl_exec($ch); // grab the hidden inputs from the form required to login $fields = getFormFields($content); $fields['email'] = $login_email; $fields['password'] = $login_pass; // set postfields using what we extracted from the form $POSTFIELDS = http_build_query($fields); // change URL to login URL curl_setopt($ch, CURLOPT_URL, $LOGINURL); // set post options curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_POSTFIELDS, $POSTFIELDS); // perform login $result = curl_exec($ch);  print $result; function getFormFields($data) {     if (preg_match('/()/is', $data, $matches)) {       $inputs = getInputs($matches[1]);       return $inputs;     } else {       die('didnt find login form');      } } function getInputs($form) {     $inputs = array();     $elements = preg_match_all("/(]+>)/is", $form, $matches);     if ($elements > 0) {         for($i = 0;$i            $el = preg_replace('/\s{2,}/', ' ', $matches[1][$i]);             if (preg_match('/name=(?:["\'])?([^"\'\s]*)/i', $el, $name)) {                 $name  = $name[1];                 $value = '';                 if (preg_match('/value=(?:["\'])?([^"\'\s]*)/i', $el, $value)) {                     $value = $value[1];                 }                 $inputs[$name] = $value;             }         }     }     return $inputs; } $grab_url='http://grab.url/alabala'; //page with the content I want to grab curl_setopt($ch, CURLOPT_URL, $grab_url); //do stuff with the info with DomDocument() etc $html = curl_exec($ch); curl_close($ch); var_dump($html); die;
