Question

我正在尝试使用以下代码发送一个POST页面：

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://www.olx.es/posting_success.php");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); 
curl_setopt($ch, CURLOPT_MAXREDIRS, 10);
curl_setopt($ch, CURLINFO_HEADER_OUT, 1); 
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTREDIR, 2);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST"); 
curl_setopt($ch, CURLOPT_POSTFIELDS, array("itemid" => $json['id'], "sh" => $json['sh']));
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-type: application/x-www-form-urlencoded"));
$response = curl_exec($ch);
curl_close($ch);

这样做我返回了服务器错误“无效请求”。

我注意到如果我通过telnet手动执行请求，我第一次返回302，尽管事实上我已经跟着他，但没有工作，也许就是这样。

通过wireshark获得客户实际发送的内容，我做错了什么？

**Hypertext Transfer Protocol:**

**Line-based text data: application/x-www-form-urlencoded:**

对不起我的英文..

Answer 1

无需发出自定义请求，发送此类标头或使用CURLINFO_HEADER_OUT 试试这个：

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://www.olx.es/posting_success.php");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); 
curl_setopt($ch, CURLOPT_MAXREDIRS, 10);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTREDIR, 2);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query( array("itemid" => $json['id'], "sh" => $json['sh']) ));
$response = curl_exec($ch);
curl_close($ch);

Answer 2

看起来您在POST请求中遇到问题。请尝试

$fields=array('itemid' => $json['id'], 'sh' =>urlencode ($json['sh']));

格式化字段

foreach($fields as $key=>$value) { $fields_string .= $key.'='.$value.'&'; }
rtrim($fields_string,'&');

然后在Curl OPt中使用

    curl_setopt($ch1,CURLOPT_POST,count($fields));
    curl_setopt($ch1,CURLOPT_POSTFIELDS,$fields_string);

Answer 3

问题是，这个表单不是multipart / form-data，然后你将创建一个查询字符串来发布。请参阅联机帮助页http://php.net/manual/en/function.curl-setopt.php。然后给出一个数组。标题将设置multipart / form-data。这是无效的请求。

解决方案

字符串很容易构建“＆amp; itemid =”。json ['id']。“＆amp; sh =”。json ['sh']; 把它放在CURLOPT_POSTFIELDS中。
