PHP-Ajax implements asynchronous uploading of pictures to Sina Picture Bed

Upload pictures to Sina Pictures asynchronously and obtain the external link address of the picture.

1. Fill in the pits

1. The Jquery library must be referenced in the page, otherwise asynchronous requests cannot be implemented. Baidu’s Jquery library is used here.

<script src="http://libs.baidu.com/jquery/2.1.4/jquery.min.js"></script>
