flask获取前端传进来的参数

# -*- coding: utf-8 -*-

# 从前端传过来的数据，统一交给request对象处理
from flask import request

def get_param_get_or_post(*keys):
    ret = []
    print("parm is:{}".format(keys))
    # 前端传进来的几种方式，将参数解析后放到对应的列表中
    for key in keys:
        if request.json:
            ret.append(request.json.get(key))
        elif request.method == "GET":
            ret.append(request.args.get(key, None))
        elif request.method == "POST":
            ret.append(request.form.get(key, None))
    print("ret is:{}".format(ret))
    # 方便位置取参
    if len(ret) == 1 and ret[0] == None:
        return ret[0]
    else:
        return ret
