python_接口开发

一、GET和POST请求

from flask import Flask,jsonify

data = {
    'name':'Jerry',
    'sex':'男',
    'age':'18'
}

app = Flask(__name__)

@app.route('/get_user',methods=['Get','post'])

def get_user():
    return jsonify(data)

app.run(host='0.0.0.0',port=8888,debug=True)

二、POST三种传参方式
1. k-v传参 request.form.get
2. url传参 request.args.get
3. json传参 request.json.get

from flask import Flask,jsonify,request

data = {
    'Jerry':{'sex':'男','age':18},
    'Tom':{'sex':'男','age':20},
}

app = Flask(__name__)

@app.route('/get_user',methods=['post'])

def get_user():
    # username = request.form['username']#key-value传参 或写成username = request.form.get('username')
    # username = request.args.get('username')#?+url传参
    username = request.json.get('username')#json传参

    if username in data:
        return jsonify(data[username])
    else:
        return jsonify(500)

app.run(host='0.0.0.0',port=8888,debug=True)
