PHP卷曲不发布数据

Question

我试图在另一个页面上做一个简单的帖子，但没有数据发布。谁知道什么是错的？

$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,"http://example.com/test.php");
curl_setopt($ch,CURLOPT_POST,true);
curl_setopt($ch,CURLOPT_POSTFIELDS,"one=val");
curl_setopt($ch,CURLOPT_HEADER,true);
curl_setopt($ch,CURLINFO_HEADER_OUT,true);
$result = curl_exec($ch);
echo print_r($result,true);
echo print_r(curl_getinfo($ch),true);

导致：

(
    [url] => http://example.com/test.php
    [content_type] => 
    [http_code] => 0
    [header_size] => 0
    [request_size] => 0
    [filetime] => -1
    [ssl_verify_result] => 0
    [redirect_count] => 0
    [total_time] => 0
    [namelookup_time] => 0
    [connect_time] => 0
    [pretransfer_time] => 0
    [size_upload] => 0
    [size_download] => 0
    [speed_download] => 0
    [speed_upload] => 0
    [download_content_length] => -1
    [upload_content_length] => -1
    [starttransfer_time] => 0
    [redirect_time] => 0
    [certinfo] => Array
        (
        )
    [redirect_url] => 
)

标题也不会打印出来。
