php的curl设置Content-Type:application/x-www-form-urlencoded头部

$_post_url = 'http://XXXXX/XXX';

$post = 'key=12&content_id='.$content_id.'&md5='.$storeStatusArr['insert_md5'].'&url='.$url;

$curl = curl_init ( $_post_url );

curl_setopt ( $curl, CURLOPT_HEADER, 0 );

$header = array ();

$header [] = 'Host:www.XXXX.co';

$header [] = 'Connection: keep-alive';

$header [] = 'User-Agent: ozilla/5.0 (X11; Linux i686) AppleWebKit/535.1 (KHTML, like Gecko) Chrome/14.0.835.186 Safari/535.1';

$header [] = 'Accept:text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8';

$header [] = 'Accept-Language: zh-CN,zh;q=0.8';

$header [] = 'Accept-Charset: GBK,utf-8;q=0.7,*;q=0.3';

$header [] = 'Cache-Control:max-age=0';

$header [] = 'Cookie:t_skey=p5gdu1nrke856futitemkld661; t__CkCkey_=29f7d98';

$header [] = 'Content-Type:application/x-www-form-urlencoded';

curl_setopt ( $curl, CURLOPT_HTTPHEADER, $header );

curl_setopt ( $curl, CURLOPT_POST, 1);

curl_setopt ( $curl, CURLOPT_POSTFIELDS, $post );

$result = curl_exec ( $curl );

curl_close ( $curl );

var_dump ( $result );

CURLOPT_POSTFIELDS参数使用数组和字符串时的不同

如果是是一个数组，则，

content_type自动为multipart/form-data

提交过去的是原始post，用$_POST［key]是无法获取

如果是字符串。

则反之。
