Python app flask+nginx+fastcgi implementing Python application Deployment----the MAC environment

For an iOS developer, writing background apps is not a necessary skill, but mastering a background language can be a complete addition to a more comprehensive understanding of the front and back architectures, while also writing back-Office applications on the fly in real-world development work.

The Flask framework itself integrates a simple server that can be called natively, whereas in this case the Python application interface can only be debugged using emulator, and if you want to debug with a real machine, we still need to deploy the server serious.

Here, we introduce a nginx collocation fastcgi to implement a local server deployment in a Mac environment.

Nginx Configuration

• A. Installing the Homebrew

-e"$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

• B. Install nginx

    sudo brew install nginx (remove sudo when error)  

• C. Start Nginx

   Code>sudo nginx  

• D. Modify the configuration file (the file is read-only by default and can change read and write permissions in the introduction, right-click menu)

    path:/usr/local/ etc/nginx/nginx.conf  

server {listen 8000 ; // nginx  listening port server_name localhost;    CharSet Utf-8 ;        Location/include  fastcgi_params; Fastcgi_param path_info   $fastcgi _script_name        ;        Fastcgi_param script_name   "" ; Fastcgi_pass 127.0 . 0 . 1  :  8008 ; // set fastcgi application listening port (note the port and the Listen 

• E. Stop Nginx

FASTCGI configuration

• Installing fastcgi

   sudo pip install flup

Python app Authoring

The following is a simple flask code example

#!/usr/bin/python fromflup.server.fcgiImportWsgiserver fromFlaskImportFlask, request fromBson.objectidImportObjectIdImportEncrypt def MyApp(environ, start_response):Start_response (' OK ', [(' Content-type ',' Text/plain ')]) def MyApp(environ, start_response):Start_response (' OK ', [(' Content-type ',' Text/plain ')]) (rquest_method,data) = Get_environ (environ)ifrquest_method==' GET ':return ' Get querystr: '+dataElse:return ' POST RequestData '+data def get_environ(environ):Rquest_method = environ["Request_method"] Data="'    ifrquest_method==' GET ': data=environ["Query_string"]Else: data = environ["Wsgi.input"].read ()return(Rquest_method,data)if__name__ = =' __main__ ': Wsgiserver (MyApp, bindaddress= (' 127.0.0.1 ',8008).

Here our local server and Python applications are deployed and can be accessed by any browser or client within the LAN. The effect is as follows:
