File MD5 value is correct API interface development

Use the web.py framework to determine if the MD5 value of a file on the server side is correct. Return the JSON format data with the following code:

#!/usr/bin/env python

#-*-Coding:utf-8-*-

App.run ()

use spawn-fcgi to hang the script under the Nginx. The commands are as follows (define your own environment variables yourself):

The directory where the-D script resides

-S socket placement location for the script

-P The location of the PID file placement for the script

--run Script (total entry)

Spawn-fcgi-d $__rootdir-s $PWD/sock/$SOCKFILE-P "$PIDFILE"--$PWD/pid/md5check.py fcgi

Interface Invocation Method:

Version number

War project name (corresponding war package)

/md5? $domainname = $version &war= $projectname

Returns whether the MD5 value of a specific war package is correct.

/md5? $domainname = $version

Returns whether the MD5 value of all packages for the project is correct.
