TypeError：强制转换为 Unicode：需要字符串或缓冲区，找到 ZipFile

Question

我有一个服务器，它应该向客户端询问文件，压缩它并将其发送给客户端。我在将 zip 文件发送到服务器时遇到了一些麻烦。

这是我收到的错误：

File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/threading.py", line 810, in __bootstrap_inner
self.run()
File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/threading.py", line 763, in run
self.__target(*self.__args, **self.__kwargs)
File "/Users/Alcantara/Desktop/Final/Server.py", line 9, in RetrFile
for dirname, subdirs, files in os.walk(Zip):
File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/os.py", line 278, in walk
names = listdir(top)
TypeError: coercing to Unicode: need string or buffer, ZipFile found

这是我的服务器：

import socket
import threading
import os
import zipfile

def RetrFile(name, sock):
    Zip = sock.recv(1024)
    Zip = zipfile.ZipFile("new_" + Zip +".zip", "w")
    for dirname, subdirs, files in os.walk(Zip):
        Zip.write(dirname)
        for filename in files:
            Zip.write(os.path.join(dirname, filename))
    Zip.close()
    with open(filename, 'rb') as f:
        bytesToSend = f.read(1024)
        sock.send(bytesToSend)
        while bytesToSend != "":
            bytesToSend = f.read(1024)
            sock.send(bytesToSend)

    sock.close()

def Main():
    host = '127.0.0.1'
    port = 5000


    s = socket.socket()
    s.bind((host,port))

    s.listen(5)

    print "Server Started."
    while True:
        c, addr = s.accept()
        print "client connedted ip:<" + str(addr) + ">"
        t = threading.Thread(target=RetrFile, args=("RetrThread", c))
        t.start()

    s.close()

if __name__ == '__main__':
    Main()

客户：

import socket

def Main():
host = '127.0.0.1'
port = 5000

s = socket.socket()
s.connect((host, port))

filename = raw_input("Filename? -> ")
if filename != 'q':
    s.send(filename)
    f = open('new_'+filename, 'wb')
    data = s.recv(1024)
    totalRecv = len(data)
    f.write(data)
    while totalRecv < filesize:
        data = s.recv(1024)
        totalRecv += len(data)
        f.write(data)
        print "{0:.2f}".format((totalRecv/float(filesize))*100)+ "% Done"
        print "Download Complete!"
    f.close()
else:
    print "File Does Not Exist!"

s.close()


if __name__ == '__main__':
    Main()

Answer 1

考虑以下几行：

Zip = sock.recv(1024)
Zip = zipfile.ZipFile("new_" + Zip +".zip", "w")
for dirname, subdirs, files in os.walk(Zip):

您使用相同的变量名称来引用接收到的数据（第 1 行和第 3 行）以及 ZipFile 对象（第 2 行）。

试试这个：

#UNTESTED
zname = sock.recv(1024)
zfile = zipfile.ZipFile("new_" + Zip +".zip", "w")
for dirname, subdirs, files in os.walk(zname):
    zfile.write(dirname)
    for filename in files:
        zfile.write(os.path.join(dirname, filename))
zfile.close()
with open("new_" + zname + ".zip", 'rb') as f:
    # ... the rest is unchanged
