为什么要使用wsgi协议

由 試著忘記壹切 提交于 2019-12-24 23:07:50
一个cs模型是由服务器和客户端组成，大多相互情况下也就是服务器端和浏览器之间的通信。通过浏览器请求服务器，然后服务器再响应浏览器。 那么如果浏览器想要请求一个python文件，例如http://127.0.0.1:8000/time.py/那么该如何实现。 首先如果浏览器只请求类似index.html的时候只要server中拥有这个index.html。并且构建一个“状态码+响应头+“\r\n”+响应体”将index.html的源代码作为响应体传入浏览器就可以实现静态页面的请求响应。 首先有这样一个想法构建一个类似请求静态页面的那样一个响应字符串。将响应体作为python程序的返回值传入浏览器会有什么样的结果。如下图 也就是说这是没办法实现和我们想象的中的那样。 引入接口这个概念，前辈们的不懈努力完成了wsgi协议。也就是只要我们可以实现wsgi接口然后通过服务器来调用这个接口就可以实现浏览器请求python文件。 python程序(ctime.py)： import time def application(env,start_response): 　　stauts = "200 ok" 　　headers = [("Content-Type","text/plain")] 　　start_response(stauts,headers) 　　return time.ctime(

问题 I am trying to get deploy a FlaskApp with Gunicorn/WSGI/Nginx. I've been trying to get this to work for awhile and can't find any thing other than the Digital Ocean guides that I've followed to a T. Below are my files I've got in their current states.

I can run /bin/gunicorn --workers 3 --bind 0.0.0.0:8000 -u nginx -g nginx wsgi and gunicorn will work. I'm pretty sure its some

Running two Django Apps on Apache with mod_auth_sspi and mod_wsgi

由 寵の児 提交于 2019-12-24 13:42:32
问题 I've been running one Django app with Single Sign-On enabled by mod_auth_sspi using mod_wsgi. Apache/2.2.21 (Win32) mod_wsgi/3.3 Python/2.7.2 mod_auth_sspi/1.0.4 Problem is, that I can't add second Django app, which uses the same modules, because I want to use Single Sign-On too. If I add second app, Apache authenticates only the first requested app. The second one throws Error 500 - Internal server error. If I restart Apache and try to request second app at first, it works. But then when I

问题 I have a working nginx production server running a Django app, using uwsgi (set up with this tutorial). nginx and uwsgi are communicating through a UNIX socket. However, as soon as I turn DEBUG = False in my Django settings, I get a 502 error. The nginx error log tells me: 2015/09/08 10:37:51 [error] 940#0: *4 upstream prematurely closed connection while reading response header from upstream, client: myIP, server: mydomain.ca, request: "GET /quests/ HTTP/1.1", upstream: "uwsgi://unix:///tmp

Schedule a python script to run on webserver

由 巧了我就是萌 提交于 2019-12-24 12:42:07
问题 I am in the process of writing a Python script, that I will want to run automatically, say every evening. I intend to run it from server, partly because I have one so I may as well as it's always on, but also to learn how to do it, and this may at some point end up as a more full 'web app' - for now though it's just reading some data, and sending an email. Solutions I've come across have ranged from cgi, wsgi, to 'microframeworks'. I'm also loosely aware of Django (is that a 'microframework'?

Apache + WSGI to run Flask, get Python ImportError: “cannot import name …” or “No module named …”

问题 Hello dear SO users and welcome to my first ever SO question, I am currently looking to deploy a Flask application using Apache and mod_wsgi . Everything was coded with Python 3.4 so I had to follow several tutorials / questions to get mod_wsgi working with my version of Python (because apt-get install gets you the 3.4 version which is Python 2.7 compatible, you have to compile it after getting it with pip in a Python 3 virtualenv for it to be the 4.x version).
