接口开发1-flask

from flask import Flask, render_template, url_for, request, json,jsonify
import datetime
import flask
app = Flask(__name__)
#设置编码
app.config['JSON_AS_ASCII'] = False
#接收参数，并返回json数据
@app.route('/reg', methods=['GET', 'POST'])
def form_data():
    #从request中获取表单请求的参数信息
    username = request.form['username']
    pwd = request.form['pwd']
    if username =='zjs':
        if pwd == '110120':
            res = {'msg':'ok','msg_code':'200','counts':'1'}
            return jsonify(res)
        else:
            res = {'msg':'pwd','msg_code':'100','counts':'2'}
            return jsonify(res)
    else:
        return jsonify({'msg':'null','msg_code':'90','counts':'3'})
    #res = {'msg':'ok','msg_code':'200','count':str(ct)}
    #return json.dumps(res,ensure_ascii=False)
    #flask中的jsonify返回json格式，json中的dumps返回的html格式
app.run(port=80,debug=True,host='0.0.0.0')  # 启动服务
# debug=True,改了代码后，不用重启，它会自动重启
# 'host='0.0.0.0'别人可以通过IP访问
