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>";
