代码测试结果：

GET方法测试：

GET方法查下测试

 

POST方法测试：input内容

{"article":{"content":"GET,POST,PUT","id":2,"title":"the way to REST"}}

 

服务器是用Python的flask实现的，代码如下：

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

articles = [
    {
        'id' : 1,
        'title':'the way to pythoon',
        'content':'tuple,list,dict'
    },
    {
        'id' : 2,
        'title':'the way to REST',
        'content':'GET,POST,PUT'
    }
]

@app.route('/api/articles',methods = ['GET'])
def get_articles():
    return jsonify( { 'articles':articles } )

@app.route('/api/articles/',methods = ['GET'])
def get_article(article_id):
    article = list(filter( lambda a : a['id'] == article_id,articles ))
    return  jsonify({'article':article[0]})

@app.route('/api/json',methods = ['POST'])
def getRequest():
    data = json.loads(request.get_data())
    return data['article']

if __name__ == '__main__':
    app.run(host='127.0.0.1', port=8877)
