使用cURL发送POST - 空数组 [英] Sending POST with cURL - Empty array

问题描述

我尝试使用cURL发送POST请求，但很遗憾，我只接收到一个空字符串。

I'm trying to send a POST request with cURL, but unfortunately I'm only receiving an empty string.

cURL：

<?php
echo "ID: " . $_POST["id"]; // here ID is not empty

$fields = array(
    'id' => urlencode($_POST["id"]),
    'name' => urlencode($_POST["name"])
);

$connection = curl_init();
curl_setopt($connection, CURLOPT_URL, "http://www.example.de/remote.php");
curl_setopt ($connection, CURLOPT_POST, true);
curl_setopt($connection, CURLOPT_POSTFIELDS, count($fields));
curl_setopt($connection, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($connection, CURLOPT_HEADER, 0);
$response = curl_exec($connection);
?>

远程服务器：

<?php
   var_dump($_POST); // shows an empty array
?>

推荐答案

您需要删除 count（$ fields），而只需使用 $ fields

You need to remove the count($fields) and instead just use $fields

curl_setopt($connection, CURLOPT_POSTFIELDS, $fields);

你实际上没有设置cURL选项来发送字段

Nowhere do you actually set the cURL option to send the fields
