Designing a RESTful API with Python and Flask

 

Python以及Flask的安装： http://blog.csdn.net/qwiwuqo/article/details/8970621

1. 安装python2.x

2. 安装esay_install

3. 安装Flask:

   1> 打开控制台:，输入easy_install virtualenv, 安装virtualenv

   2> 配置虚拟环境： virtualenv myvir，相应路径下会多一个文件夹myvir

   3> 在myvir目录的Scripts下，输入activate.bat进入虚拟环境，然后输入esay_install Flask

   4> 控制台输入python hello.py

   5> 浏览器输入http://127.0.0.1:500访问对应的api

 

示例，hello.py文件：

from flask import Flask  
app=Flask(__name__)  
@app.route('/')  
def hello_world():  
    return "Hello World"  
if __name__ == '__main__':  
    app.run()

 

示例，bookItems.py：

from flask import Flask, jsonify
from flask import abort
app = Flask(__name__)  

bookItems = [
    {
		"id": "1000",
		"name": "groovy",
		"price": "30",
		"author": "Jack"
	},
	{
		"id": "1001",
		"name": "java",
		"price": "32",
		"author": "Jimmy"
	},
	{
		"id": "1002",
		"name": "c#",
		"price": "32",
		"author": "Jimmy"
	},
	{
		"id": "1003",
		"name": "html",
		"price": "32",
		"author": "Jimmy"
	},
	{
		"id": "1004",
		"name": "english",
		"price": "32",
		"author": "Jimmy"
	},
	{
		"id": "1005",
		"name": "sport",
		"price": "32",
		"author": "Jimmy"
	}
]


@app.route('/api/v1/books', methods=['GET'])
def get_bookItems():
    return jsonify({'books': bookItems})

@app.route('/api/v1/books/<book_id>', methods=['GET'])
def get_book(book_id):
    book = [book for book in bookItems if book['id'] == book_id]
    if len(book) == 0:
        abort(404)
    return jsonify({'book': book[0]})

if __name__ == '__main__':  
    app.run(debug = True)
