PHP curl post x-www-form-urlencoded

接口在postman里面测试是成功的。但是PHP curl post这个 接口竟然失败

后面想明白了。请求头的原因。这个接口的请求头是x-www-form-urlencoded。所以curl post也要改成这样

if($url == "" || $timeout <= 0){
    return false;
}
$post_data = http_build_query($post_data);//重点
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_HEADER, 0);//不抓取头部信息。只返回数据
curl_setopt($curl, CURLOPT_TIMEOUT, (int)$timeout);//超时设置
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);//1表示不返回bool值
curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_HTTPHEADER, array('Content-Type: application/x-www-form-urlencoded'));//重点
curl_setopt($curl, CURLOPT_POSTFIELDS, $post_data);
$data = curl_exec($curl);
if (curl_errno($curl)) {
    return curl_error($curl);
}
curl_close($curl);
