@TODO 
自定义img标签图片提取正则（情景描述：有些网页的 img 的图片地址不是用src属性标注的，比如微信网页版用 data-src 来标注图片地址。） 
感谢 @守心斋 提出建议。
@待测试 
1.随机数参数url形如http://xxxx.jpg?123。导致插件不能正常下载图片 (@walkskyer) 
2.前台HTTP，HTTPS后台出现问题。无法正常显示插件页面。 (@Jakes)
@待定功能 
1.自定义img标签图片提取正则 (@守心斋) 
2.兼容SAE版WORDPRESS （@苏洋 ） 
3.自定义路径 （@mapleaf）
<ul>
<li>
2.1.0 
修复：下载类似于http://mmbiz.qpic.cn/mmbiz/xxxxxx/640?wx_fmt=jpeg&tp=webp&wxfrom=5&wx_lazy=1 
这种url的图片的时候，当文章中有多个图片，底部（后下载的）的图片会将前面的图片覆盖的bug.
</li>
<li>
2.0.9
</li>
<li>修复：远程图片url没有文件名后缀时，自动添加后缀。这样在WP文章里单独点击图片文件链接时，可避免某些服务器把没有后缀的图片文件当二进制文件下载的问题。</li>
<li>修复:Error:SyntaxError: Unexpected token {. Check your HTTP Server error log or PHP error log to see what happend. (thanks to @守心斋)</li>
<li>修复: 远程服务器图片有空格到本地 LAMP 服务器显示不出来的问题 (thanks to @再袭面包屋)</li>
<li>
修复: Notice: Undefined offset: 1 in /PATH-TO-WP-ROOT-DIR/wp-includes/vars.php on line 31 (thanks to @YYK)
</li>
<li>
2.0.0 版完全重写。相比于原来1.0.2版的插件，有非常大的改进。
</li>
<li>原来的插件是在文章更新时自动下载远程图片，如果图片非常多的话，这样容易导致执行超时或只有部分图片被下载了。</li>
<li>这次的新版采用的是ajax异步请求的方式让多个文件同时下载。效率和易用性都得到很大改善。</li>
</ul>
<h3>Arbitrary section</h3>
<pre><code>if remote server is　 unreachable OR remote server Set against hotlinking，then the image url will remain as what it is in the post.
also ,this plugin will not handel with the situation when the remote server returns 302 http status.
the ssl verify has been set to FALSE due to some reasons.

wpautosave

“Wp-autosave” plugin is for automatically saving posts being written in the Classic Editor
Note: 
This plugin works as an additional module to the <a href="https://wordpress.org/plugins/classic-editor/" rel="ugc">Classic Editor</a> plugin by <a href="https://github.com/WordPress/classic-editor/" rel="nofollow ugc">WordPress Contributors</a> since <a href="https://wordpress.org/support/wordpress-version/version-5-0/" rel="ugc">WordPress version 5.0+</a>, because the original Classic Editor was replaced with a new editor – Gutenberg. 
So the original Classic Editor plugin is required to work with WP-Autosave plugin for all actual WordPress versions.
In case of older versions of WordPress (<5.0), the original Classic Editor plugin is not required because Classic Editor is used by default.
Major features of plugin: 
– Auto-save post to drafts at regular time intervals by multipart requests. (To check the functionality it’s enough to have the rights to create an entry in the wp-blog (you can test through a user-account) – you will see all requests through the developer tools or some other tools) 
– Intellectual immediately auto-save post to drafts when you change the text in the editor 
– You can attach a time-stamp to request through the settings of the plugin (appendix time of saving in the query) 
– You can set your auto-save interval 
– You can choose the type of saving – by time intervals or when content is changed
