我不确定这是否可能，但如果可能，我至少需要知道从哪里开始。我想在我不拥有的网站上填写表格，使用我拥有的网站的字段。
特别是这个电脑游戏网站http://www.g2a.com/，以及那里的搜索表单，即
<input type="text" class="mp-h-main ui-autocomplete-input" id="product-autocomplete" placeholder="Search a game" data-rel="active" autocomplete="off" state="closed">
它似乎加载了Ajax或jQuery，并且网站上似乎没有常规的搜索功能。有没有一个好的已知方法，或者在这种情况下我几乎没有机会？
谨致问候，John
使用firefox的实时http头之类的东西来嗅探表单发布内容，并使用php-ccurl进行模拟，即：
<?php
$productName = rawurlencode("DOOM STEAM CD-KEY PREORDER GLOBAL");
$url = "https://www.g2a.com/lucene/search/quick?jsoncallback=jQuery111005943281338131983_1462669099509&phrase=$productName&isWholesale=false&cn=&skip=28837%2C28838%2C28847%2C28849%2C28852%2C28856%2C28857%2C28858%2C28859%2C28860%2C28861%2C28862%2C28863%2C28867%2C28868%2C29472%2C29473%2C29474%2C33104&start=0&rows=5&_=1462669099513";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
