PHP用CURL发送Content-type为application/json的HTTP/HTTPS请求

<?php

$headers = array(

　　"Content-type: application/json;charset='utf-8'", 

　　"Accept: application/json", 

　　"Cache-Control: no-cache", 

　　"Pragma: no-cache", 

);

$ch = curl_init($url);

curl_setopt($ch, CURLOPT_TIMEOUT, 60); //设置超时

$url = '这里为请求地址';

if(0 === strpos(strtolower($url), 'https')) {

　　curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); //对认证证书来源的检查

　　curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0); //从证书中检查SSL加密算法是否存在

}

curl_setopt($ch, CURLOPT_POST, TRUE);

$data = array(0=>1,1=>2);

curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data)); 

curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); 

curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); 

$rtn = curl_exec($ch);//CURLOPT_RETURNTRANSFER 不设置  curl_exec返回TRUE 设置  curl_exec返回json(此处) 失败都返回FALSE

curl_close($ch);
