根據(jù)不同配置文件調用不同的驗證函數(shù)檢查輸入。可以根據(jù)需求更改驗證函數(shù)的邏輯。

代碼如下:
def VerifyData(func):

    def VerifyInt(data):
        assert(int(data) > 0)

    def VerifyString(data):
        assert(len(data) > 10)

    def inner(*args, **kvargs):

        print args
        print kvargs

        assert(len(args) > 1)
        if args[1] == "int.txt":
            VerifyInt(args[0])
        elif args[1] == "string.txt":
            VerifyString(args[0])

        func(*args, **kvargs)

    return inner

@VerifyData
def WriteData(text, filepath):
    print "WriteData"
    print text
    print filepath

WriteData("1234567890", "int.txt")
