c++代码获取一个字符串的md5值并输出

#include "md5.h"#include <string>#include <iostream>#include <cstring>#include <cstdio>#include <cstdlib>using namespace std;extern "C"{    void getStrMd5(char* filePath)    {        MD5 md5(filePath);        std::string str = md5.md5();        printf("%s", str.c_str());    }}

生成动态库，供python调用
g++ md5.cpp getStringMd5.cpp -fPIC -shared -o getHash.so

获取字符串的md5值：getHashValue.py

#!/usr/bin/pythonfrom ctypes import *import os import systarget = (sys.argv)[1]libtest = cdll.LoadLibrary(os.getcwd() + '/getHash.so') print libtest.getStrMd5(target)

处理得到哈希目录脚本：process.py
32位md5值，前4位用作目录名，后28位用作文件名

#!/usr/bin/pythonimport sysimport osimport os.pathimport shutilimport commandssrcPath = os.path.join((sys.path)[0], "res")desPath = os.path.join((sys.path)[0], "HashRes")if os.path.exists(desPath):    shutil.rmtree(desPath)os.mkdir(desPath)def process(path):    for parent, dirnames, filenames in os.walk(path):        for file in filenames :            if file != ".DS_Store" :                fullPath = parent + "/" + file                splitPath = fullPath[len(path)+1:]                command = "python getHashValue.py " + splitPath                f = os.popen(command)                data = f.readlines()[0][0:31]                fileNewPath = desPath + "/" + data[0:4]                if not os.path.exists(fileNewPath):                    os.mkdir(fileNewPath)                shutil.copyfile(parent+"/"+file, fileNewPath+"/"+data[4:32])process(os.path.join((sys.path)[0], "res"))
