034文件上传

因为这个是简单的，所以很容易
思想就是建立连接后，客户端发送文件名字和大小到服务端，服务端接受后，客户端开始发送文件，直到发完。具体的还是要看下面的代码，我自己实现了一遍

import  socket
import  os

def get_server_socket():
    sk = socket.socket()
    address = ('127.0.0.1',8888)
    sk.bind(address)
    sk.listen(3)
    return sk

def  wait_connect(sk):
    print('waitconnecting...')
    conn, addr = sk.accept()
    return conn

if  __name__ == '__main__':
    sk = get_server_socket()
    conn = wait_connect(sk)
    BASIC_DIR = os.path.dirname(os.path.abspath(__file__))
    while True:
        data = str(conn.recv(1024),'utf8')
        cmd,filename,file_size = data.split('|')
        path = os.path.join(BASIC_DIR,'yuan',filename)
        file_size = int(file_size)
    f = open(path,'wb')
    has_receive = 0
    while has_receive != file_size:
        data = conn.recv(1024)
        f.write(data)
        has_receive += len(data)
    f.close()

import  socket
import  os

def  get_client_socket():
    sk = socket.socket()
    address = ('127.0.0.1',8888)
    sk.connect(address)
    return sk

if __name__ == '__main__':
    BASIC_DIR = os.path.dirname(os.path.abspath(__file__))
    sk = get_client_socket()
    while  True:
        inp = input('>>>').strip()#post|11.png
        cmd,path = inp.split('|')
        path = os.path.join(BASIC_DIR,path)#使用系统的路径拼接
        filename = os.path.basename(path)#拿到文件名字
        file_size = os.stat(filename).st_size#拿到文件的大小
        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('上传完成')
