爲什麼我無法提交表單？ PHP cURL

Question

我正在嘗試編寫一個腳本，該腳本可以獲取本月的數據使用情況，並瀏覽我使用cURL的url。不幸的是，我並不熟悉它。這是到目前爲止我的代碼：

<?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" ; 

?> 

出於某種原因，雖然，這是行不通的。我嘗試了很多變化，但輸出總是一樣的。它給了我原來的頁面。有誰知道我做錯了什麼？幾個小時以來，我一直在嘲笑我。

謝謝！

我不是100％確定的，但在查看url的源代碼之後，我覺得你應該縮小表單的行爲，而不是表單所在的頁面。因此，您正在模擬提交，因此您應該嘗試將表單內容提交給表單的操作。

<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> 

嘗試改變：

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

到

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

也改變

$data = array(
    'MAC' => "$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' 
) ;
