Pythonsocket上传和下载文件

服务端：

import socket ,os,jsonserver = socket.socket(socket.AF_INET,socket.SOCK_STREAM)server.bind(('',9999))server.listen(5)while True:    conn,addr = server.accept()    print('conn is addr :',addr)    while True:        cmd_obj = conn.recv(1024).decode()        print('cmd_obj=%s'%cmd_obj)        if not cmd_obj:break        if cmd_obj == 'get':            filename = r'D:\\IStudy\\Oracle\\1.jpg'            basefilename = os.path.basename(filename)            myfile = open(filename,'rb')            myfile_size = os.path.getsize(filename)            print(basefilename)            data = {'filename':basefilename,'filesize':myfile_size}            json_obj = json.dumps(data)            conn.send(json_obj.encode())            for readline in myfile:                conn.send(readline)            else:                conn.send(b'finish')                print('file send is finish')

客户端：

import socket,jsonclient = socket.socket(socket.AF_INET,socket.SOCK_STREAM)client.connect(('127.0.0.1',9999))while True:    data = input('>>')    client.send(data.encode())    json_obj = client.recv(1024).decode()    file_info = json.loads(json_obj)    filename = file_info['filename']    filesize = file_info['filesize']    print('filename=',filename,'filesize=',filesize)    recevie_size = 0    myfile = open(filename,'wb')    while recevie_size < filesize:                filedata = client.recv(1024)        myfile.write(filedata)        recevie_size += len(filedata)    else:        myfile.close()        print('receive file finished!')

测试过图片，文本都可以。
