python用web.py 搭建一个简单文件读取服务

import web
import os

urls=(
    '/readFile/(.*)','readFile'
)
app = web.application(urls,globals())

class readFile:
    def GET(self,path):
        file = os.open(path,os.O_RDONLY)
        fSize = os.path.getsize(path)
        fileValue = os.read(file,fSize)
        os.close(file)
        return fileValue
if __name__ == '__main__':
        app.run()
