我正在尝试使用 curl 模拟来自 FireFox 的 LiveHTTP Replay 的 http 帖子。我相信远程站点有某种验证来检查请求的来源。如果请求来自他们自己的域，那么很好。当我尝试运行 php curl 脚本时，我可以从 Live HTTP 标头中看到我正在发出 GET 请求而不是 POST。除此之外，主机，预计为 www.aliexpress.com 已自动更改为 localhost。

如果我使用 Live HTTP Replay，它工作正常。所以我复制了标题数据并尝试用 curl 实现但无济于事。例如：

http://www.aliexpress.com/cross-domain/shoppingcart/index.html

我尝试使用以下内容实现原始标头（上图）：

<?php
// create a new cURL resource

$fields = array(
                        'productId' => 523523529,
                        'standard' => '',
                        'quantity' => 8,
                        'country' => 'MY',
                        'company' => 'CPAM',
                        'cartfrom' => 'main_store',
                        'skuAttr' => ''
                );

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

echo $fields_string . "<br/>";

$ch = curl_init();

// set URL and other appropriate options
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Host: www.aliexpress.com",
                                           "Content-Type: application/x-www-form-urlencoded",

谢谢你的帮助！

尝试设置CURLOPT_POST为真

curl_setopt($ch, CURLOPT_POST, 1);

我认为您应该稍微修改一下代码：

  • urlencode设置值时删除CURLOPT_URL
  • 从中删除HostandContent-length标头CURLOPT_HTTPHEADER
  • 用来http_build_query建立你的$fields_string

出于调试目的，我将响应设置为CURLOPT_RETURNTRANSFERvartrue转储。

我的工作代码

$fields = array(
                        'productId' => 523523529,
                        'standard' => '',
                        'quantity' => 8,
                        'country' => 'MY',
                        'company' => 'CPAM',
                        'cartfrom' => 'main_store',
                        'skuAttr' => ''
                );

$fields_string = http_build_query($fields);

echo $fields_string . "<br/>";

$ch = curl_init();

// set URL and other appropriate options
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/x-www-form-urlencoded", 
                                           "Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8",
                                           "Accept-Language: en-US,en;q=0.5",
                                           "Accept-Encoding: gzip, deflate",
                                           "X-Requested-With: XMLHttpRequest"));                                                                        //proceeding with the login.
