测试1 传入python dict字典

1 sever服务端

目录结构

|---- /hello.py|----/templates/|----|-----------/index.html

hello.py

from flask import Flask,render_template,requestapp = Flask(__name__)@app.route("/")def index():    return render_template("index.html")@app.route("/login",methods = ['GET', 'POST'])def login():    if request.method == "POST":        username = request.form.get('username')        password = request.form.get('password')        if username=="zhangsan" and password=="123":            return "<h1>welcome, %s !</h1>" %username        else:            return "<h1>login Failure !</h1>"        else:        return "<h1>login Failure !</h1>"if __name__ == '__main__':    app.run(debug=True)

index.html

<form action="/login" method="post">    username: <input type="text" name="username">    password: <input type="password" name="password">    <input type="submit" id="submit"></form>

2 client客户端调用

#coding=utf-8import requestss = requestsdata={"username":"zhangsan","password":"123",}r = s.post('http://127.0.0.1:5000/login', data)print r.status_codeprint r.headers['content-type']print r.encodingprint r.text

先启用服务端程序，然后可以利用客户端程序调用以及返回结果。

测试2 传入json字符串

1 server 端

#!/usr/bin/python# -*- coding: utf-8 -*-import jsonfrom flask import Flaskfrom flask import requestfrom flask import redirectfrom flask import jsonifyapp = Flask(__name__)@app.route('/' , methods=['GET', 'POST'])def index():    if request.method == 'POST':        a = request.get_data()        dict1 = json.loads(a)        return json.dumps(dict1["data"])    else:        return '<h1>只接受post请求！</h1>'@app.route('/user/<name>')def user(name):    return'<h1>hello, %s</h1>' % nameif __name__ =='__main__':    app.run(port='5000')

2 client端

#coding=utf-8import requestsimport jsons = requests#data={"username":"zhangsan","password":"123",}data={ "opr": "add", "data": { "userName": "98997", "disc": "hudihiudhu", "expDate":"2", "ip": [ "10.10.11.1", "10.10.11.2", "10.10.11.3" ] } }data = json.dumps(data)r = s.post('http://127.0.0.1:5000/', data)#r = s.post('http://127.0.0.1:5000/login', data)print r.status_codeprint r.headers['content-type']print r.encodingprint r.text
