Python实现文件上传

server端：

import socket
import os


sk = socket.socket()
address = ('127.0.0.1',8000)
sk.bind(address)
sk.listen(3)
print('writing............')
BASE_DIR = os.path.dirname(os.path.abspath(__file__))
while True:
    conn,addr = sk.accept()
    # print(addr)
    while True:
        data = conn.recv(1024)       #开始接收
        cmd,filename,file_size = str(data,'utf8').split('|')
        path = os.path.join(BASE_DIR,'yuan',filename)
        file_size = int(file_size)

        f = open(path,'ab')
        has_receive = 0
        while has_receive != file_size:
            data = conn.recv(1024)
            f.write(data)
            has_receive +=len(data)
        f.close()

conn.close()
sk.close()

client端：

import socket
import os
sk = socket.socket()
address = ('127.0.0.1',8000)
print(sk)
sk.connect(address)
BASE_DIR = os.path.dirname(os.path.abspath(__file__))
while True:
    inp = input('>>>').strip()#post|123.jpg
    cmd,path = inp.split('|')
    path = os.path.join(BASE_DIR,path)    #路径拼接
    filename = os.path.basename(path)
    file_size = os.stat(path).st_size
    file_info = 'post|%s|%s'%(filename,file_size)
    sk.sendall(bytes(file_info,'utf8'))
    f = open(path, 'rb')
    has_sent = 0
    while has_sent != file_size:

        data = f.read(1024)
        sk.sendall(data)
        has_sent +=len(data)
    f.close()
    print('上传成功！！！！')
sk.close()

上传结果：

先运行server端：

再运行client端：然后上传文件

 

本次上传文件，所上传的文件以及文件目录都在server端client端同意目录下进行
