flask獲取前端傳進來的參數

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

# 從前端傳過來的數據，統一交給request對象處理
from flask import request

def get_param_get_or_post(*keys):
    ret = []
    print("parm is:{}".format(keys))
    # 前端傳進來的幾種方式，將參數解析后放到對應的列表中
    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))
    # 方便位置取參
    if len(ret) == 1 and ret[0] == None:
        return ret[0]
    else:
        return ret
