PHP curl + post + multipart / form
我试图取消这个网站https://www.machinemart.co.uk/，我需要将产品添加到购物车以获取特定数据。 该网站使用邮寄请求将产品添加到购物车。
我试图添加的产品的URL：https://www.machinemart.co.uk/p/clarke-amf-panel-for-kc6-and-kc10/
这里是一个头和身体请求的例子：

我尝试添加标题请求，发送参数作为数组...但仍然不起作用，我做的不好？
一个解决方案，虽然我不得不说，代码需要一些额外的工作，以便更坚实（我标记在代码中的评论容易出错的部分）
1.将任何产品页面网址（不是来自产品列表）也可能有产品列表的解决方案，但此示例在产品页面中工作。
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch,CURLOPT_URL,"https://www.machinemart.co.uk/p/clarke-ctj2qlp-2-tonne-quick-lift-low-profile/"); //type your url here as explained above
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch,CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/525.13 (KHTML, like Gecko) Chrome/0.A.B.C Safari/525.13");
curl_setopt($ch,CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch,CURLOPT_FOLLOWLOCATION, true );
curl_setopt($ch,CURLOPT_COOKIEJAR,$_SERVER['DOCUMENT_ROOT'].'/extra path here/'.$_COOKIE['PHPSESSID'].'.txt');
curl_setopt($ch,CURLOPT_COOKIEFILE,$_SERVER['DOCUMENT_ROOT'].'/extra path here/'.$_COOKIE['PHPSESSID'].'.txt');
$data = curl_exec($ch);
curl_close($ch);
前一个片段将获得url并设置一个COOKIE
2.接下来，我们将通过使用PHP DOM库从表单中获取数据，为使购物车功能正常工作，所有必填字段都在表单元素中。 在我的例子中，我假设第二个表单元素实际上是产品形式，但是您必须仔细检查哪一个是正确的
libxml_use_internal_errors(true);
$siteData = new DOMDocument();
$siteData->loadHTML($data);
$forms = $siteData->getElementsByTagName("form");
$inputs = $forms->item(1)->getElementsByTagName("input");
$search = array();
for($i=0;$i<$inputs->length;$i++){
if($inputs->item($i)->getAttribute("class")!="greyBtn"){
$search[$inputs->item($i)->getAttribute("name")] = $inputs->item($i)->getAttribute("value");
}
}
$submitURL = "https://www.machinemart.co.uk".$forms->item(1)->getAttribute("action");
代码获取所有名称和值并将它们添加到名为$ search的数组中，同时创建另一个名为$ submitURL的变量，这是第3步中curl将用作参数的url。
3.我们再次调用curl，将$ submitURL变量和$ search数组作为目标url作为post参数。
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch,CURLOPT_URL,$submitURL);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch,CURLOPT_POSTFIELDS,http_build_query($search));
curl_setopt($ch,CURLOPT_POST, true);
curl_setopt($ch,CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/525.13 (KHTML, like Gecko) Chrome/0.A.B.C Safari/525.13");
curl_setopt($ch,CURLOPT_HTTPHEADER, array('Content-Type: application/x-www-form-urlencoded'));
curl_setopt($ch,CURLOPT_HEADER, 0);
curl_setopt($ch,CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch,CURLOPT_FOLLOWLOCATION, true );
curl_setopt($ch,CURLOPT_COOKIEJAR,LOG_DIR.'/'.$_COOKIE['PHPSESSID'].'.txt');
curl_setopt($ch,CURLOPT_COOKIEFILE,LOG_DIR.'/'.$_COOKIE['PHPSESSID'].'.txt');
$data = curl_exec($ch);
curl_close($ch);
echo $data;
$ data变量保存页面作为结果，如果你回应它（虽然丑陋，因为css丢失），你会看到产品在购物车中。
