为什么我不能提交表格？ PHP cURL [英] Why can't I submit form? PHP cURL

问题描述

我想写一个脚本，将获取我的数据用量的一个月，并导航我使用cURL的网址。不幸的是，我不熟悉它。这是我的代码到目前为止：

I am trying to write a script that will get my data usage for the month, and to navigate the url I am using cURL. Unfortunately, I am not familiar with it. This is my code so far:

<?php

$url = 'https://apps.nwtel.ca/cable_usage/login.jsp' ;
$id = "------------" ;

$ch = curl_init() ;
curl_setopt( $ch, CURLOPT_URL, "$url" ) ;
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true ) ;
curl_setopt( $ch, CURLOPT_POST, true ) ;
curl_setopt( $ch, CURLOPT_SSL_VERIFYPEER, false ) ;
curl_setopt( $ch, CURLOPT_FOLLOWLOCATION, true ) ;

$data = array(
    'MAC' => "$id",
    'submit_btn' => 'submit'
) ;

curl_setopt( $ch, CURLOPT_POSTFIELDS, $data ) ;
$output = curl_exec( $ch ) ;
curl_close( $ch ) ;

echo "$output\n" ;

?>

由于某种原因，这不起作用。我试过这么多变化，但输出总是相同的。它给我原始页面。有人知道我在做什么错了吗？

For some reason though, this does not work. I've tried so many variations, but the output is always the same. It gives me the original page. Does anyone know what I am doing wrong? I've been banging my head on this for hours.

谢谢！

推荐答案

我不是100％肯定，但是看着url的源，我觉得你应该卷曲窗体的动作，而不是窗体所在的页面。你模拟一个提交，因此您应该尝试将表单内容提交到表单的操作。

I am not 100% sure, but after looking at that source of the url, I feel like you should be curling the action of the form, not the page the form is located in. You are simulating a submit, therefore you should try to submit the forms content to the action of the form.

<form method="post" action="j_security_check" id="usage_login">
    <input type="hidden" name="j_target_url" value="secured/index.jsp" />
    <div class="form_input">
    <label for="MAC">HFC or CM MAC Address:</label>
    <input type="Text" name="MAC" id="MAC" onKeyPress="onKeyPress(this.form)" />
    <a href="#mac_num_help" title="Your HFC or CM MAC Address is located on the sticker on the bottom of your modem" class="help">MAC Address Help</a>
    <input type="hidden" name="j_username" id="j_username" />
    </div>
    <div class="form_input">
    <input type="hidden" name="j_password" id="j_password" maxlength="6" size="7" value="123456" />
    </div>
    <div class="form_input">
    <label for="submit_btn">&nbsp;</label>
    <input type="submit" name="submit_btn" id="submit_btn" value="Submit" onclick="fixAndSubmit(this.form)" />
    </div>
</form>

尝试更改：

$url = 'https://apps.nwtel.ca/cable_usage/login.jsp' ;

到

$url = 'https://apps.nwtel.ca/cable_usage/j_security_check' ;

也会更改

$data = array(
    'MAC' => "$id",
    'submit_btn' => 'submit'
) ;

到

$data = array(
    'MAC' => "$id",
    'submit_btn' => 'submit',
    'j_password' => '123456',
    'j_username' => '3D3D3D3D3D3D' //should be your MAC address all capitalize without using special characters
    'j_target_url' => 'secured/index.jsp'
) ;
