python文件上传

实现：client上传图片文件到server

如下图所示，图片与post_client.py在同一当前目录

-------------------post_server.py-----------------------------------------

import subprocess
#subprocess.Popen,主要用Popen这个类实现shell
import os
import socket
sk=socket.socket()
print(sk)
address=('127.0.0.1',8005)
sk.bind(address)
sk.listen(3)
print('waiting.....')
BASE_DIR=os.path.dirname(os.path.abspath(__file__))
while True:
    conn,addr = sk.accept()
    print(addr)
    while True:
       data=conn.recv(1024)     #接收
       cmd,filename,filesize=str(data,'utf-8').split('|')   #用三个变量解析接收的并用|分隔
       path=os.path.join(BASE_DIR,'yuan','filename') #路径拼接，这里指定在yuan下
       filesize=int(filesize)

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


--------------------post_client.py------------------------

import socket
import os
sk=socket.socket()
print(sk)
address=('127.0.0.1',8005)
sk.connect(address)
BASE_DIR=os.path.dirname(os.path.abspath(__file__))

while True:
    inp=input('>>>').strip()    #post|1.png
    cmd,path = inp.split('|')     #两个变量接收，并用|分隔开
    path=os.path.join(BASE_DIR,path)   #路径拼接-----绝对路径

    filename=os.path.basename(path)   #你放参数路径，它会取到最后的文件名字
    file_size=os.stat(path).st_size  # 看文件大小
    file_info='post|%s|%s'%(filename,file_size)   #
    sk.sendall(bytes(file_info,'utf-8'))  #发过去
#循环发
    f = open(path, 'rb')  # 打开
    has_sent=0         #已发的
    while  has_sent !=file_size:
        data=f.read(1024)       #每次1024个的一段段发
        sk.sendall(data)
        has_sent+=len(data)
    f.close()
    print('上传成功')




sk.close()
