我有一个数据提交系统，它通过 curl 将值发布到这样的 url：

  $URL="http://some_url/"; 
           $ch = curl_init(); 
           curl_setopt($ch, CURLOPT_URL,$URL); 
       curl_setopt($ch, CURLOPT_POST, 1); 
       curl_setopt ($ch, CURLOPT_HTTPHEADER, array ('Content-Type:application/x-www-form-urlencoded;application/xml'));
       curl_setopt($ch, CURLOPT_POSTFIELDS, "First Name=".$firstname."&Last Name=".$lastname."&Daytime Phone=".$dayphone."&Evening Phone=".$evephone."&DeliveryCode=".$deliveryCode."&username=".$username."&password=".$password);
    echo curl_exec ($ch); 
    curl_close ($ch);

当我检查网络控制台时，它显示执行了 GET 请求而不是 POST 请求。可能是什么问题。

我不知道为什么您的代码不起作用，但我给您一个起作用的代码；它可能不是解决方案，但它会帮助你理解 cUrl；

根据需要调整代码；
