php向七牛上传base64编码的图片

与大家分享一下我的代码：

<?php
require_once 'vendor/autoload.php';
header('Access-Control-Allow-Origin:*');

use Qiniu\Auth;

$bucket = '要上传的空间名';
$accessKey = '你的accessKey';
$secretKey = '你的secretKey';
$auth = new Auth($accessKey, $secretKey);
$upToken = $auth->uploadToken($bucket, null, 3600);//获取上传所需的token


function request_by_curl($remote_server,$post_string,$upToken) { 

 $headers = array();
 $headers[] = 'Content-Type:image/png';
 $headers[] = 'Authorization:UpToken '.$upToken;
 $ch = curl_init(); 
 curl_setopt($ch, CURLOPT_URL,$remote_server); 
 //curl_setopt($ch, CURLOPT_HEADER, 0);
 curl_setopt($ch, CURLOPT_HTTPHEADER ,$headers);
 curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
 //curl_setopt($ch, CURLOPT_POST, 1);
 curl_setopt($ch, CURLOPT_POSTFIELDS, $post_string);
 curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
 curl_setopt($ch, CURLOPT_TIMEOUT, 30);
 $data = curl_exec($ch); 
 curl_close($ch); 
 
 return $data; 
} 
$str="base64编码的字符串";
echo "<pre>";
echo request_by_curl('http://upload.qiniu.com/putb64/-1',$str,$upToken);
echo "</pre>";
