Apprunner 的新手，并试图让普通 Python 应用程序成功部署，但继续未能通过 TCP 健康检查。以下是服务和 Apprunner 控制台日志的一些相关部分：

我的应用程序是一个原始的、非联网的 Python 应用程序，我在其中添加了一个 SimpleHTTPRequestHandler 运行在一个 TCPServer 上，配置为作为单独的线程运行，如下所示：
import socketserver
import threading
from http.server import SimpleHTTPRequestHandler
# handler for server
class HealthCheckHandler(SimpleHTTPRequestHandler):
def do_GET(self) -> None:
self.send_response(code=200)
self.send_header("Content-Type", "text/html")
self.end_headers()
self.wfile.write("""<html><body>hello, client.</body><html>""".encode('utf-8'))
# runs the server
def run_healthcheck_server():
with socketserver.TCPServer(("127.0.0.1", 80), HealthCheckHandler) as httpd:
print(f"Fielding health check requests on: 80")
httpd.serve_forever()
# dummy
def my_app_logic():
while True:
print('hello, server.')
time.sleep(5)
# wrapper to run primary application logic AND TCPServer
def main():
# run the server in a thread
threading.Thread(target=run_healthcheck_server).start()
# run my app
my_app_logic()
if __name__ == "__main__":
main()
这在我的本地机器上运行良好，我看到“你好，客户”。在我的浏览器中转到 127.0.0.1 并且在我的控制台中每 5 秒发送一连串 hello, server. 消息。
我对网络知之甚少，我将其合并到应用程序中的唯一原因是为了促进我无法在 AppRunner 服务中禁用的 AWS HealthCheck。我试图了解问题是我如何try 处理来自 AWS 健康检查器的 TCP 请求，还是 Apprunner 方面的其他问题。
