Question

嗨，我在登录和下载网页时遇到了一些麻烦。我正在尝试做的是登录我学校的moodle站点并将主页保存为字符串，这样我就可以使用解析器来挑选某些信息并构建一个gwt应用程序。

这是我到目前为止：在moodleLogin.html

<html>
<body>

    <form name="lms" action="moodlephp.php" method="post">
    <input type="text" name="username" id="username" /><br/>
    <input type="password" name="password" id="password" />
    <input type="hidden" name="domain" id="domain" value="students.ltu.edu.au" />
    <input type="submit" name="Login" id="Login" />
    </form>
    <div id="test"></div>
</body>
</html>

in moodlephp.php

<?php   

    $username = $_POST["username"];
    $password = $_POST["password"];
    $domain = $_POST["domain"];

    $postfields = array( "username" => $username, "password" => $password, "domain" => $domain );
    $working_folder = "\cookies";

    $cookiefile = tempnam($working_folder, "cookies"); 
    $urlbase = "https://www.latrobe.edu.au/lms";
    $agent = $_SERVER['HTTP_USER_AGENT'];
    $debug = "";
    $debughandle = "";


    // get session cookies to set up the Moodle interaction
    $ch = curl_init(); 
    curl_setopt($ch, CURLOPT_USERAGENT, $agent);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
    curl_setopt($ch, CURLOPT_COOKIEFILE, $cookiefile);
    curl_setopt($ch, CURLOPT_COOKIEJAR, $cookiefile);
    curl_setopt($ch, CURLOPT_VERBOSE, $debug);
    if ($debug) curl_setopt($ch, CURLOPT_STDERR, $debughandle);

    curl_setopt($ch, CURLOPT_URL, $urlbase . "/login/index.php"); 
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
    $result = curl_exec ($ch);
    curl_close ($ch);


    $ch = curl_init(); 
    curl_setopt($ch, CURLOPT_USERAGENT, $agent);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
    curl_setopt($ch, CURLOPT_COOKIEFILE, $cookiefile);
    curl_setopt($ch, CURLOPT_COOKIEJAR, $cookiefile);
    if(!$cookiefile) echo('empty');
    else echo($cookiefile);
    curl_setopt($ch, CURLOPT_VERBOSE, $debug);
    if ($debug) curl_setopt($ch, CURLOPT_STDERR, $debughandle);

    curl_setopt($ch, CURLOPT_URL, $urlbase . '/login/index.php');
    curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($postfields)); 
    curl_setopt($ch, CURLOPT_POST, 1); 
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0);
    curl_setopt($ch, CURLOPT_HEADER, 1);
    $result = curl_exec ($ch);
    curl_close ($ch); 

    if (!$result || !preg_match("/HTTP\/1.1 303 See Other/", $result))
    {
    unlink($cookiefile);
    header("HTTP/1.0 403 Forbidden");
    die("Username/password incorrect.\n");

    }

    // get session key

    $ch = curl_init(); 
    curl_setopt($ch, CURLOPT_USERAGENT, $agent);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
    curl_setopt($ch, CURLOPT_COOKIEFILE, $cookiefile);
    curl_setopt($ch, CURLOPT_COOKIEJAR, $cookiefile);
    curl_setopt($ch, CURLOPT_VERBOSE, $debug);
    if ($debug) curl_setopt($ch, CURLOPT_STDERR, $debughandle);

    curl_setopt($ch, CURLOPT_URL, $urlbase . "/question/import.php?courseid=" . $courseid); 
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
    $result = curl_exec ($ch);
    curl_close ($ch);

    if (!preg_match("/sesskey=(\w*)/", $result, $matches))
    {
    unlink($cookiefile);
    header("HTTP/1.0 500 Internal Server Error");
    die("Could not determine sesskey.\n");
    }

    $sesskey = $matches[1];

    echo $result;
?>

非常感谢任何帮助。我目前收到的只是“用户名/密码不正确。”

我一直在尝试按照这里发布的代码 - ＆gt; http://moodle.org/mod/forum/discuss.php?d=153580 提前谢谢。

我想我知道你要做什么，但这是一种非常低效的方式。一个更好的方法是使用webservices使用XMLRPC或SOAP进行连接（使用PHP的内置库非常容易）并以这种方式请求您需要的信息。 Moodle 2.0内置了一个Web服务堆栈 - 只需按照说明here启用它。 Moodle 1.9将需要你添加一个插件，其中有几个模块和plugins目录。 OKTech Webservices也许是最好的。

您真正想从首页获得哪些信息？

使用cURL下载moodle主页
