与大家分享一下我的代码：

1. <?php
2. require_once 'vendor/autoload.php';
3. header('Access-Control-Allow-Origin:*');
4. use Qiniu\Auth;
5. $bucket = '要上传的空间名';
6. $accessKey = '你的accessKey';
7. $secretKey = '你的secretKey';
8. $auth = new Auth($accessKey, $secretKey);
9. $upToken = $auth->uploadToken($bucket, null, 3600);//获取上传所需的token
10. function request_by_curl($remote_server,$post_string,$upToken) {
11. $headers = array();
12. $headers[] = 'Content-Type:image/png';
13. $headers[] = 'Authorization:UpToken '.$upToken;
14. $ch = curl_init();
15. curl_setopt($ch, CURLOPT_URL,$remote_server);
16. //curl_setopt($ch, CURLOPT_HEADER, 0);
17. curl_setopt($ch, CURLOPT_HTTPHEADER ,$headers);
18. curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
19. //curl_setopt($ch, CURLOPT_POST, 1);
20. curl_setopt($ch, CURLOPT_POSTFIELDS, $post_string);
21. curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
22. curl_setopt($ch, CURLOPT_TIMEOUT, 30);
23. $data = curl_exec($ch);
24. curl_close($ch);
25. return $data;
26. }
27. $str="base64编码的字符串";
28. echo "<pre>";
29. echo request_by_curl('http://upload.qiniu.com/putb64/-1',$str,$upToken);
30. echo "</pre>";
