python学习笔记（十七）flask模块写接口

import flask,json
from tools import op_mysql  #op_mysql()
# 接口，后台服务
server = flask.Flask(__name__) #把咱们这个app这个python文件当做一个server
@server.route('/get_user',methods=['get','post'])
def get_all_user():
    sql = 'select * from bt_stu;'
    res = op_mysql(
        host='211.149.218.16',
        user='jxz', password='123456',  # port这里一定要写int类型
        port=3306, db='jxz', charset='utf8', sql=sql)
    response = json.dumps(res,ensure_ascii=False) #把list转成json
    return response #return 的时候只能return字符串

@server.route('/add_user',methods=['post'])
def add_user():
    user_id = flask.request.values.get('id')  #这里的参数就是调用接口的时候传入的参数
    username = flask.request.values.get('u') #
    if user_id and username:
        sql = "insert into stu values ('%s','%s');"%(user_id,username)
        res = op_mysql(
            host='211.149.218.16',
            user='jxz', password='123456',  # port这里一定要写int类型
            port=3306, db='jxz', charset='utf8', sql=sql)
        response = {'code':308,'msg':'添加成功'}
    else:
        response = {'code':503,'msg':'必填参数未填！'}
    return json.dumps(response,ensure_ascii=False)


server.run(port=8080,debug=True)
