I wrote a file upload demo using the php-sdk of qiniu. The local operation is normal. The following results are displayed during the upload to the server:

1. Run the 'php demo. php' command on the server terminal. The result is normal and the file is uploaded successfully. 2. Access 'HTTP: // xxx.com/demo.php' in a browser. After a long time, the file fails to be uploaded due to a 502error.

Attached demo. php code:

  UploadToken ($ bucket); // construct the UploadManager object $ uploadMgr = new UploadManager (); $ data = file_get_contents('11.jpg '); $ rt = $ uploadMgr-> upload', $ data ); print_r ($ rt );
