您可以使用 PHPcURL 浏览 &向网站提交表单，但这取决于网站的设置方式.大多数都设置了安全检查来防止机器人，并且很难让一切正常工作.

You can use PHP cURL to browse & submit forms to websites, but it does depend on how the website is setup. Most have security checks in place to prevent bots and can be tricky to get everything to work right.

我花了一点时间，想出了这个登录脚本.没有有效的用户名和密码，我无法验证它是否成功，但应该做你需要的.这个简短的示例首先浏览页面以设置任何 cookie 并抓取提交表单所需的 __VIEWSTATE 值.然后使用您提供的用户名/密码提交表单.

I spent a little bit of time and came up with this login script. Without a valid username and password I can't verify that it is successful, but should do what you need. This short example first browses to the page to set any cookies and scrape a __VIEWSTATE value needed to submit the form. It then submits the form using the username/password you provide.

<?php

// Login information
$username = 'test';
$password = 'mypass';
$utcoffset = '-6';
$cookiefile = '/writable/directory/for/cookies.txt';

$client = new Client($cookiefile);

// Retrieve page first to store cookies 
$page = $client -> get("https://pm.officeally.com/pm/login.aspx");
// scrape __VIEWSTATE value
$start = strpos($page, '__VIEWSTATE" value="') + 20;
$end = strpos($page, '"', $start);
$viewstate = substr($page, $start, $end - $start);

// Do our actual login
$form_data = array(
    '__LASTFOCUS' => '', 
    '__EVENTTARGET' => '',
    '__EVENTARGUMENT' => '',
    '__VIEWSTATE' => $viewstate,
    'hdnUtcOffset' => $utcoffset,
    'Login1$UserName' => $username,
    'Login1$Password' => $password,
    'Login1$LoginButton' => 'Log In'
);
$page = $client -> get("https://pm.officeally.com/pm/login.aspx", $form_data);

// cURL wrapper class    
class Login {
    private $_cookiefile;

    public function __construct($cookiefile) {
        if (!is_writable($cookiefile)) {
            throw new Exception('Cannot write cookiefile: ' . $cookiefile);
        }
        $this -> _cookiefile = $cookiefile;
    }

    public function get($url, $referer = 'http://www.google.com', $data = false) {
        // Setup cURL
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_REFERER, $referer);
        curl_setopt($ch, CURLOPT_COOKIEFILE, $this -> _cookiefile);
        curl_setopt($ch, CURLOPT_COOKIEJAR, $this -> _cookiefile);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
        curl_setopt($ch, CURLOPT_AUTOREFERER, true);
        curl_setopt($ch, CURLOPT_MAXREDIRS, 10);

        // Is there data to post
        if (!empty($data)) {
            curl_setopt($ch, CURLOPT_POST, 1);
            curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
        }

        return curl_exec($ch);
    }

}
