Question

我正在尝试登录某个网站以获取一些数据，但我每次只会看到登录表单并且cookie文件仍为空。

我使用以下代码：

<?php

$cookie_file = 'cookie.txt';

if (! file_exists($cookie_file) || ! is_writable($cookie_file)){
    echo 'Cookie file missing or not writable.';
    exit;
}//cookie_file is writable, so this is not the issue

$login_url = 'https://portal.processing.com';

//These are the post data username and password
$post_data = 'username=USERNAME&password=PASSWORD';

//Create a curl object
$ch = curl_init();

//Set the useragent
$agent = $_SERVER["HTTP_USER_AGENT"];
curl_setopt($ch, CURLOPT_USERAGENT, $agent);

//Set the URL
curl_setopt($ch, CURLOPT_URL, $login_url );

//This is a POST query
curl_setopt($ch, CURLOPT_POST, 1 );

//Set the post data
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);

//We want the content after the query
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

//Follow Location redirects
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);

/*
Set the cookie storing files
Cookie files are necessary since we are logging and session data needs to be saved
*/

curl_setopt($ch, CURLOPT_COOKIEJAR, realpath($cookie_file));
curl_setopt($ch, CURLOPT_COOKIEFILE, realpath($cookie_file));

curl_exec($ch);

curl_setopt($ch, CURLOPT_URL, 'https://portal.processing.com/query.transaction-view.php?id=9452931');

//Execute the action to login
$postResult = curl_exec($ch);

echo $postResult;

?>

我出错的任何想法？

Answer 1

查看登录表单的源代码，它包含：

<input type="hidden" name="action" value="login" />
<input type="hidden" name="redirect" value="">

将这些值添加到POST值中，看看是否会产生所需的结果。

编辑：

我再看一下，表单通过jQuery发布到https://portal.processing.com/forms/login_check.php。请尝试发布到该页面。

Answer 2

从CURLOPT_COOKIEJAR＆amp;中删除realpath（） CURLOPT_COOKIEFILE
在创建参数数组时使用urlencode，

$ fields = array（'username'=＆gt; urlencode（$ uname）， 'password'=＆gt; urlencode（$ passwd），）; foreach（$ fields as $ key =＆gt; $ value）{ $ fields_string。= $ key。'='。$ value。'＆amp;'; }
将$ fields_string修剪为，

修剪（$ fields_string）;

CURL - 只显示登录表单
