serverSocket.on(“connect”, (clientSocket: socket.TCPSocketConnection) => { 
  console.log(waitForRequest connect ${clientSocket.clientId}); // 1 
clientSocket.on(“message”, (data) => { // MessageCallBackBean 
  this.onMessage(clientSocket, data); // 2 
}); 
clientSocket.on(“error”, (err: Error) => { 
  console.log(waitForRequest-clientSocket-error,name=${err.name},msg=${err.message},stackTrace=${err.stack}); 
// closeSocket(clientSocket, false) 
}) 
clientSocket.on(“close”, () => { 
console.log(“waitForRequest-clientSocket-connection-close”); 
// closeSocket(clientSocket, true) 
}) 
console.log(waitForRequest connect2 ${clientSocket.clientId}); 
})

这个方法偶现无法正常响应message方法，也就是// 1处能正常打印日志，// 2处日志无法正常打印，导致无法请求数据无法传输；

2. httpRequest.request方法无法返回正常值，均收到timeout的exceptionawait httpRequest.requestInStream(url, option)

两个问题：

1. connection.destroy(); 不能写在finally里面，要写在then和catch里面

2. onMessage方法里面，data格式不正确，使用类似这种是可以的。 const data = “HTTP/1.1 200 OK\r\nContent-Length: 12\r\n\r\nHello, World!”;

修改之后运行成功的日志
