使用 PHP 和 Curl 登录 Google，Cookie 关闭？

Login to Google with PHP and Curl, Cookie turned off?

提问by kazuo

I have this code for logging into Google using Simple DOM Parser with curl. I've tried adding in the cookiejar file, but to no avail. I keep getting the message:

我有使用带有 curl 的 Simple DOM Parser 登录 Google 的代码。我试过添加 cookiejar 文件，但无济于事。我不断收到消息：

Your browser's cookie functionality is turned off. Please turn it on.

您的浏览器的cookie功能被关闭。请打开它。

Any idea on how to solve this?

关于如何解决这个问题的任何想法？

Here's my code for reference:

这是我的代码供参考：

$html = file_get_html('https://accounts.google.com/ServiceLogin?hl=en&service=alerts&continue=http://www.google.com/alerts/manage');

//... some code for getting post data here

$curl_connection = curl_init('https://accounts.google.com/ServiceLoginAuth');
curl_setopt($curl_connection, CURLOPT_CONNECTTIMEOUT, 30);
curl_setopt($curl_connection, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)");
curl_setopt($curl_connection, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl_connection, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl_connection, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($curl_connection, CURLOPT_COOKIEJAR, COOKIEJAR);
curl_setopt($curl_connection, CURLOPT_COOKIEFILE, COOKIEJAR);
curl_setopt($curl_connection, CURLOPT_HEADER, true);  
curl_setopt($curl_connection, CURLOPT_RETURNTRANSFER,1);
curl_setopt($curl_connection, CURLOPT_CONNECTTIMEOUT, 120);
curl_setopt($curl_connection, CURLOPT_TIMEOUT, 120);
curl_setopt($curl_connection, CURLOPT_POSTFIELDS, $post_string);

$result = curl_exec($curl_connection);
curl_close($curl_connection);

echo $result;

Here is some modified code that works.

这是一些有效的修改代码。

It first requests the login page to get the initial cookies and extract the required values for the login form. Next it performs a post to the login service. It then checks to see if it is trying to use javascript and meta tags to redirect to the destination URL.

它首先请求登录页面获取初始 cookie 并提取登录表单所需的值。接下来，它对登录服务执行发布操作。然后它会检查它是否正在尝试使用 javascript 和元标记重定向到目标 URL。

It seemed like you already have code for grabbing the form fields, so I didn't post mine, but if you need it let me know. Just make sure $formFieldsis an associative array with keys being the field name, and the value being the field value.

看起来您已经有了用于获取表单字段的代码，所以我没有发布我的代码，但是如果您需要它，请告诉我。只要确保$formFields是一个关联数组，键是字段名称，值是字段值。
