Django vs other Python web frameworks?

左心房为你撑大大i 提交于 2019-12-17 10:14:51
问题 I've pretty much tried every Python web framework that exists, and it took me a long time to realize there wasn't a silver bullet framework, each had its own advantages and disadvantages. I started out with Snakelets and heartily enjoyed being able to control almost everything at a lower level without much fuss, but then I discovered TurboGears and I have been using it (1.x) ever since. Tools like Catwalk and the web console are invaluable to me. But with TurboGears 2 coming out which brings

Python : How to parse the Body from a raw email , given that raw email does not have a “Body” tag or anything

How Python web frameworks, WSGI and CGI fit together

拜拜、爱过 提交于 2019-12-17 04:08:45
问题 I have a Bluehost account where I can run Python scripts as CGI. I guess it's the simplest CGI, because to run I have to define the following in .htaccess : Options +ExecCGI AddType text/html py AddHandler cgi-script .py Now, whenever I look up web programming with Python, I hear a lot about WSGI and how most frameworks use it. But I just don't understand how it all fits together, especially when my web server is given (Apache running at a host's machine) and not something I can really play

Django框架请求生命周期

安稳与你 提交于 2019-12-16 22:41:05
先看一张图吧! 1、请求生命周期 - wsgi, 他就是socket服务端,用于接收用户请求并将请求进行初次封装,然后将请求交给web框架(Flask、Django) - 中间件,帮助我们对请求进行校验或在请求对象中添加其他相关数据,例如:csrf、request.session - 路由匹配 - 视图函数,在视图函数中进行业务逻辑的处理,可能涉及到:orm、templates => 渲染 - 中间件,对响应的数据进行处理。 - wsgi,将响应的内容发送给浏览器。 2、什么wsgi wsgi:web服务网关接口 实现该协议的模块: - wsgiref(测试版本,性能特别差) - werkzurg - uwsig wsgiref示例: from wsgiref.simple_server import make_server def run_server(environ, start_response): start_response('200 OK', [('Content-Type', 'text/html')]) return [bytes('<h1>Hello, web!</h1>', encoding='utf-8'), ] #字节 if __name__ == '__main__': httpd = make_server('127.0.0.1', 8000, run

项目部署 基于ubuntu 16.04系统,使用 Gunicorn + Nginx 进行布署 阿里云服务器控制台: https://www.aliyun.com https://ecs.console.aliyun.com/#/home 1、进入控制台,查看实例创建情况 2、给安全组配置规则,添加5000端口(一并加上5001端口) 3、利用命令行进行远程服务器登录 ssh 用户名@ip地址 相关环境安装 以下操作都在远程服务器上进行操作 (ubuntu 16.04) 1)先更新 apt 相关源 sudo apt-get update 2)mysql安装 apt-get install mysql-server apt-get install libmysqlclient-dev 3)redis安装 sudo apt-get install redis-server 4)安装虚拟环境 pip install virtualenv pip install virtualenvwrapper 使得安装的virtualenvwrapper生效,编辑~/.bashrc文件,内容如下: export WORKON_HOME=$HOME/.virtualenvs export PROJECT_HOME=$HOME/workspace source /usr/local/bin

Flask 应用如何部署

文章目录 Flask 应用如何部署 1. Why Flask+Gunicorn+Nginx 1.1 Why? 1.2 Anything More? 2. Flask网站如何部署 2.1 Gunicorn 2.2 Nginx 3. 基于Docker的Flask网站部署 3.1 构建Flask网站的镜像 3.2 Nginx 相关的配置 3.3 用Docker-compose编排服务 4. 其他Python web网站的部署 Flask 应用如何部署 1. Why Flask+Gunicorn+Nginx Flask+Gunicorn+Nginx是最常用的Flask部署方案,大家深究过为何用这样的搭配么? 1.1 Why? Flask 是一个web框架,而非web server,直接用Flask拉起的web服务仅限于开发环境使用,生产环境不够稳定,也无法承受大量请求的并发,在生茶环境下需要使用服务器软件来处理各种请求,如Gunicorn、 Nginx或Apache,而Gunicorn+Nginx的搭配,好处多多,一方面基于Nginx转发Gunicorn服务,在生产环境下能补充Gunicorn服务在某些情况下的不足,另一方面,如果做一个Web网站,除了服务外,还有很多静态文件需要被托管,这是Nginx的强项,也是Gunicorn不适合做的事情。所以,基于Flask开发的网站

Django: 'unicode' object has no attribute 'tzinfo'. Production server only

谁说我不能喝 提交于 2019-12-14 03:49:01
问题 I'm stumped. With my local set up (python manage.py runserver) everything runs fine. With my production set up (wsgiserver.CherryPyWSGIServer), I get 'unicode' object has no attribute 'tzinfo' when my program tries to convert datetime2(7) from the database to local time in the pytz module. Using Django 1.9. Both set ups use django-pyodbc-azure to connect to the same mssql database. In fact to troubleshoot this, both use the same settings files. # settings.py ... DATABASES = { 'default': {

django rest_framework开发十大规范
