【问题描述】：

我正在制作一个 Growtopia 服务器模拟器 （出于教育目的：我会对其进行测试，将来可能会制作一个私人服务器。我希望我能完成） 奇怪的是，我刚刚收到此错误，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：

【问题讨论】：

你能包含堆栈跟踪吗？

标签： python serversocket

【解决方案1】：

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

在要写入的字符串末尾添加一个 .encode()，或者在其前面加上一个 b。
