python實現對以‘&’串連的參數串排序後計算md5

本程式實現了對’&’符號串連的http參數串排序後再計算md5.
主要步驟為：1.參數串以&為分割符拆成list，
2. 對list進行排序
3. 把排序完的list再用&串連為string
4. 對string計算md5
參數串例如
str1=”languageId=0&accessToken=0E4730695CDD9B4F8D56B8107171F525-001407107122545&outTradeNo=148879135312969764307b4a86&payPlatform=1&packageName=com.baidu.vodx&payMode=2&price=0.01&payInfoId=15543373&version=6.2&productname=book&sourceType=1&thirdAppCallBack=&timeStamp=1488793412&thirdappName=com.qq.vod”

代碼在Python3.4.3調試通過。

#!/usr/bin/env python#coding=gbkimport structimport hashlibdef md5(input):    input =input.encode('utf-8');    md5sign = hashlib.md5()    md5sign.update(input)    str = md5sign.digest()    data = struct.unpack("IIII", str)    md5value = data[0] << 96 | data[1] << 64 | data[2] << 32 | data[3]    return md5valueif __name__ == "__main__":    str1="languageId=0&accessToken=0E4730695CDD9B4F8D56B8107171F525-001407107122545&outTradeNo=148879135312969764307b4a86&payPlatform=1&packageName=com.baidu.vodx&payMode=2&price=0.01&payInfoId=15543373&version=6.2&productname=book&sourceType=1&thirdAppCallBack=&timeStamp=1488793412&thirdappName=com.qq.vod"    #string 拆分為List     strSplit=str1.split('&')  #str.split(str="", num=string.count(str)).    print (strSplit)    print ('\n')    #List排序    strSorted=sorted(strSplit)    print (strSorted)    print ('\n')    #List轉為string，以&串連    strConvert = '&'.join(strSorted)    print(strConvert+'\n')    print (md5(strConvert))

處理結果：
[‘languageId=0’, ‘accessToken=0E4730695CDD9B4F8D56B8107171F525-001407107122545’, ‘outTradeNo=148879135312969764307b4a86’, ‘payPlatform=1’, ‘packageName=com.baidu.vodx’, ‘payMode=2’, ‘price=0.01’, ‘payInfoId=15543373’, ‘version=6.2’, ‘productname=book’, ‘sourceType=1’, ‘thirdAppCallBack=’, ‘timeStamp=1488793412’, ‘thirdappName=com.qq.vod’]

[‘accessToken=0E4730695CDD9B4F8D56B8107171F525-001407107122545’, ‘languageId=0’, ‘outTradeNo=148879135312969764307b4a86’, ‘packageName=com.baidu.vodx’, ‘payInfoId=15543373’, ‘payMode=2’, ‘payPlatform=1’, ‘price=0.01’, ‘productname=book’, ‘sourceType=1’, ‘thirdAppCallBack=’, ‘thirdappName=com.qq.vod’, ‘timeStamp=1488793412’, ‘version=6.2’]

可以看出，得益於Python強大的庫函數，寫這個程式基本不用知道演算法。
