使用Python搭建http服务器

由 纵饮孤独 提交于 2020-01-29 09:05:21
David Wheeler有一句名言：“计算机科学中的任何问题，都可以通过加上另一层间接的中间层解决。”为了提高Python网络服务的可移植性，Python社区在PEP 333中提出了Web服务器网关接口(WSGI，Web Server Gateway Interface)。 为了提高Python网络服务的可移植性，Python社区在PEP 333中提出了Web服务器网关接口(WSGI，Web Server Gateway Interface)。 WSGL标准就是添加了一层中间层。通过这一个中间层，用Python编写的HTTP服务就能够与任何Web服务器进行交互了。现在，WSGI已经成为了使用Python进行HTTP操作的标准方法。 按照标准的定义，WSGI应用程序是可以被调用的，并且有两个输入参数。 1、WSGI 下面是第一段代码，第一个参数是environ，用于接收一个字典，字典中提供的键值对是旧式的CGI环境集合的拓展。第二个参数本身也是可以被调用的，习惯上会将其命名为start_response()，WSGI应用程序通过这个参数来声明响应头信息。 # 用WSGI应用形式编写的简单HTTP服务。 #!/usr/bin/env python3 # A simple HTTP service built directly against the low-level WSGI

Calculate size multipart/form-data encoded file

由 喜夏-厌秋 提交于 2020-01-24 09:04:15
问题 I'm writing an application that should receive a file and store it. One way of storing would be to upload it to another server (e.g. filehoster). Server-side I'm using Python and the Pyramid-framework. I already get rid of the problem getting the file while the client is uploading, and wrapped the app returned by make_wsgi_app in another class. This class handles the upload request and I'm able to only read the file. My current problem is getting the file size while the client is uploading.

django框架--底层架构

由 佐手、 提交于 2020-01-24 08:32:00
目录 零、参考 一、对于web服务的理解 二、对于wsgi协议的理解 三、自定义一个简单的基于wsgi协议的web框架 四、django中的server实现 五、django中的application实现 六、django的底层调用链 七、总结 零、参考 https://www.jianshu.com/p/679dee0a4193 https://www.letiantian.me/2015-09-10-understand-python-wsgi/ 一、对于web服务的理解 web 服务应该至少包含两个模块： web 服务器和 web 应用程序，两个模块在功能和代码上解耦。 web 服务器负责处理 socket 调用、 http 数据解析和封装等底层操作。 web 应用程序负责业务处理、数据增删改查、页面渲染/生成等高层操作。 web 服务器一旦接收到 http 请求，经过自身的解析后就会调用 web 应用程序来处理业务逻辑，并得到 web 应用程序的返回值，再经过自身的封装发送给客户端。 二、对于wsgi协议的理解 在 web 服务器和 web 应用程序之间需要定义一个接口规则，这也叫协议，用于明确两者之间以什么样的形式交互数据。即： web 服务器应该以什么样的形式调用web应用程序，而 web 应用程序又应该定义成什么形式。 python 下规定的 web

WSGI Middleware for OAuth authentication

由 余生颓废 提交于 2020-01-22 12:16:44
问题 I have build a very small web application using Flask. Now I would like to add very basic authentication to the site (I don't need authorization). As Flask does not support auth&auth out of the box, I'd like to plug in a WSGI middleware doing this job. The web-app is only used by roughly 10 people, all of them are on Facebook. So I'd like to use Facebook's OAuth interface. I've quickly looked through the wsgi.org list of WSGI Middleware and noticed two things: The available middleware is
