是否有一个列表，其中包含不同的基于Python的REST框架的建议，以便在服务器端使用以编写自己的RESTful API？优选有利有弊。请随时在此处添加推荐。 :) #1楼看一眼 Itty （博客文章）瓶子 web.py 朱诺 #2楼我强烈推荐使用TurboGears或Bottle： TurboGears的：比django更简洁更灵活，更少面向HTML 但是：不那么有名瓶子：非常快很容易学习但是：简约而不成熟 #3楼以下是有关REST的CherryPy文档中的讨论： http ： //docs.cherrypy.org/dev/progguide/REST.html 特别是它提到了一个名为MethodDispatcher的内置CherryPy调度程序，它根据HTTP动词标识符（GET，POST等）调用方法。 #4楼 Piston 是一个非常灵活的框架，用于为Django应用程序创建RESTful API。 #5楼惊讶没人提到烧瓶。 from flask import Flask app = Flask(__name__) @app.route("/") def hello(): return "Hello World!" if __name__ == "__main__": app.run() 来源： oschina 链接： https://my

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

阅读更多关于 How to extend the Turbogears 2.1 login functionality

问题 I'm using Turbogears 2.1 and repoze.who/what and am having trouble figuring out how to extend the basic authentication functionality. I am essentially attempting to require users to activate their account via an emailed link before they can login. If they try to login without activating their account, I want to display an appropriate error message. The default Turbogears functionality simply displays one message for all errors. I created my own authentication plugin which works fine. It won't

问题 I have been developing under Python/Snowleopard happily for the part 6 months. I just upgraded Python to 2.6.5 and a whole bunch of libraries, including psycopg2 and Turbogears. I can start up tg-admin and run some queries with no problems. Similarly, I can run my web site from the command line with no problems. However, if I try to start my application under Aptana Studio, I get the following exception while trying to import psychopg2: ('dlopen(/Library/Frameworks/Python.framework/Versions/2

Turbomail Integration with Pyramid

阅读更多关于 Turbomail Integration with Pyramid

问题 I am in need of a method to send an email from a Pyramid application. I know of pyramid_mailer, but it seems to have a fairly limited message class. I don't understand if it's possible to write the messages from pyramid_mailer using templates to generate the body of the email. Further, I haven't seen anything regarding whether rich-text is supported, or if it's just simple plain-text. Previously, I was using Turbomail with the Pylons framework. Unfortunately there doesn't appear to be any

纠结应该先学Python还是Java？看完就有数了

阅读更多关于纠结应该先学Python还是Java？看完就有数了

准备学习编程前，你一定会打开电脑搜索一下“先学 Python 还是先学 Java ？”扑面而来的是海量回答。如果你问一名 Java 程序员，肯定会建议你先学 Java ，因为他们认为Python像个乳臭未干的黄毛小子。但如果你问Python程序员，可能会得到一个完全相反的答案，他们认为Java是刻板啰嗦的老大爷，而人生苦短，我用 Python 。但别担心，今天我们将会从语言特色学习曲线职业方向市场需求等多个方面为你解答 “选择 Python 还是Java的人生难题” 语言历史 Python：生而为简 Python是一门拥有简洁语法的高级编程语言。一个名为Guido van Rossum的荷兰大佬在1991年设计了它。Rossum设计这门语言的初衷，就是为了让代码读起来更轻松，并且让程序员们比起用其他语言，可以写更少的代码，事半功倍。 Java：出生就想当老大而Jame Gosling在1995年设计了Java。 Java是一门以Class为单位，高度面向对象的高级编程语言。Java的设计初衷是“写一次代码，在哪里都可以用。” Java可以完成任何规模的任务，所以它也是很多公司在做商业级项目的时候的普遍选择。语言本身 Python: 语法简洁，容易上手 Java：语法稍微复杂从语言本身来说，Python是出了名的简洁，容易上手
