Python SocketServer 错误：TypeError：需要类似字节的对象，而不是“str”

Question

我正在制作一个 Growtopia 服务器模拟器（出于教育目的：我会测试它，也许将来会制作一个私人服务器。我希望我能完成）奇怪的是，我刚收到这个错误，我正在使用堆栈溢出来修复该死的错误谢谢大家...

这是我的代码：

import http.server
import socketserver

class ServerHandler(http.server.BaseHTTPRequestHandler):
            def do_POST(self):
                self.send_response(200)
                self.end_headers()
                self.wfile.write("server|127.0.0.1\nport|17091\ntype|1\n#maint|Server is not available!\n\nbeta_server|127.0.0.1\nbeta_port|17091\n\nbeta_type|1\nmeta|localhost\nRTENDMARKERBS1001")
            def do_GET(self):
                self.send_response(200)
                self.end_headers()
                self.wfile.write("server|127.0.0.1\nport|17091\ntype|1\n#maint|Server is not available!\n\nbeta_server|127.0.0.1\nbeta_port|17091\n\nbeta_type|1\nmeta|localhost\nRTENDMARKERBS1001")
            def log_message(self, format, *args):
                return

            Handler = http.server.SimpleHTTPRequestHandler
PORT = 80
HOST = ""



OUT_HOST = HOST
info = OUT_HOST,PORT

httpd = socketserver.TCPServer((HOST, PORT), ServerHandler)

print("Server Port : ", PORT)
if "" in (OUT_HOST):
    print("Server Hostname : ", "localhost")
else:
    print("Server Hostname : ", HOST)

httpd.serve_forever()

这是堆栈跟踪：

Answer 1

根据提供的没有堆栈跟踪的信息，我相信您可能应该向 wfile.write 提供字节而不是字符串。

在要写入的字符串的末尾添加一个 .encode()，或者在它前面加上一个 b。
