从服务器搜索文件并发送给客户端

Question

我想制作一个程序，可以在服务器的计算机中搜索文件，如果服务器中存在该文件，则通知客户端（如果未通知客户端），然后将结果打印到客户端，然后将文件发送至客户。

这是我的客户端代码

client.py

    import socket

    HOST = '127.0.0.1'
    PORT = 2000

    def find_all(search):
        socket1 = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        socket1.connect((HOST, PORT))
        search = input("Enter file name: ")
        socket1.send(search.encode('utf-8'))
        found = socket1.recv(1024).decode('utf-8')
        result = socket1.recv(1024).decode('utf-8')
        print(result)
        not_found = socket1.recv(1024).decode('utf-8')

        with open(result, 'wb') as file_to_write:
            while True:
                result = socket1.recv(1024).decode("utf-8")
                print(result)
                if not result:
                    break
                file_to_write.write(result.encode('utf-8'))
        file_to_write.close()
        print('Download Successful')
        socket1.close()
        return


    print(find_all('search'))

这是来自客户端的错误

Traceback (most recent call last):
  File "/cient.py", line 29, in <module>
    print(find_all('search'))
  File "/client.py", line 16, in find_all
    with open(result, 'wb') as file_to_write:
FileNotFoundError: [Errno 2] No such file or directory: ''

这是我的服务器端代码：

server.py

    import socket
    import os
    from pathlib import Path

    HOST = '127.0.0.1'
    PORT = 2000
    socket1 = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    socket1.bind((HOST, PORT))
    socket1.listen(5)

    conn, addr = socket1.accept()
    result = []
    search = conn.recv(1024).decode('utf-8')
    path = str(Path.home())
    for root, dirs, files in os.walk(path):
        if search in files:
            found = socket1.send("File found".encode('utf-8'))
            print('data=%s', found)
            result.append(os.path.join(root, search))
            socket1.send(result.encode('utf-8'))
        else:
            not_found = socket1.send("File not found".encode('utf-8'))
            print('data=%s', not_found)
    while True:
        with open('result', "rb") as file_to_send:
            for result in file_to_send:
                conn.sendall(result.encode('utf-8'))
        print('Send Successful')

这是来自服务器的错误

Traceback (most recent call last):
  File "/server.py", line 22, in <module>
    not_found = socket1.send("File not found".encode('utf-8'))
BrokenPipeError: [Errno 32] Broken pipe

当我同时运行这两个代码时，它可以工作，但不能运行；如果文件不存在或文件夹中不存在，则不会将输出显示给客户端。
