if(!function_exists('tps_curl_post3')){
function tps_curl_post3($url, $postData) {
$postData = json_encode($postData);
$curl = curl_init(); //初始化
curl_setopt($curl,CURLOPT_URL,$url); //设置url
curl_setopt($curl,CURLOPT_HTTPAUTH,CURLAUTH_BASIC); //设置http验证方法
curl_setopt($curl, CURLOPT_TIMEOUT,30);
curl_setopt($curl,CURLOPT_RETURNTRANSFER,1); //设置curl_exec获取的信息的返回方式
curl_setopt($curl,CURLOPT_POST,1); //设置发送方式为post请求
