go run app.go always run in the background

问题

我有一个简单的HTTP服务器，并且我想将其作为后台进程运行。

我的server.go文件如下：

  1. package main
  2.     
  3. import (
  4.     "fmt"
  5.     "net/http"
  6. )
  7.     
  8. func handler(w http.ResponseWriter, r *http.Request) {
  9.     fmt.Fprintf(w, "Hi there X, I love %s!", r.URL.Path[1:])
  10. }
  11.     
  12. func main() {
  13.     http.HandleFunc("/", handler)
  14.     http.ListenAndServe(":8080", nil)
  15. }

然后我运行：go run server.go

VS Code的Launch.json配置如下：

  1. {
  2.   "version": "0.2.0",
  3.   "configurations": [
  4.     {
  5.       "name": "Launch",
  6.       "type": "go",
  7.       "request": "launch",
  8.       "mode": "debug",
  9.       "remotePath": "",
  10.       "port": 2345,
  11.       "host": "127.0.0.1",
  12.       "program": "${workspaceRoot}",
  13.       "env": {},
  14.       "args": [],
  15.       "showLog": true
  16.     }
  17.   ]
  18. }

更新：我在VS Code终端中遇到了以下错误：

  1. 2017/04/07 16:41:41 debugger.go:257: created breakpoint: &api.Breakpoint{ID:1, Name:"", Addr:0x12063ef, File:"/Users/X/Documents/X/play/go/server.go", Line:9, FunctionName:"main.handler", Cond:"", Tracepoint:false, Goroutine:false, Stacktrace:0, Variables:[]string(nil), LoadArgs:(*api.LoadConfig)(nil), LoadLocals:(*api.LoadConfig)(nil), HitCount:map[string]uint64{}, TotalHitCount:0x0}

I have a simple HTTP server, and I want to run it as a process in the background.

my server.go file is like:

  1. package main
  2.     
  3. import (
  4.     "fmt"
  5.     "net/http"
  6. )
  7.     
  8. func handler(w http.ResponseWriter, r *http.Request) {
  9.     fmt.Fprintf(w, "Hi there X, I love %s!", r.URL.Path[1:])
  10. }
  11.     
  12. func main() {
  13.     http.HandleFunc("/", handler)
  14.     http.ListenAndServe(":8080", nil)
  15. }

And I run: go run server.go

VS Code Launch.json:

  1. {
  2.   "version": "0.2.0",
  3.   "configurations": [
  4.     {
  5.       "name": "Launch",
  6.       "type": "go",
  7.       "request": "launch",
  8.       "mode": "debug",
  9.       "remotePath": "",
  10.       "port": 2345,
  11.       "host": "127.0.0.1",
  12.       "program": "${workspaceRoot}",
  13.       "env": {},
  14.       "args": [],
  15.       "showLog": true
  16.     }
  17.   ]
  18. }

Update: I get this error in VS Code Terminal:

  1. 2017/04/07 16:41:41 debugger.go:257: created breakpoint: &api.Breakpoint{ID:1, Name:"", Addr:0x12063ef, File:"/Users/X/Documents/X/play/go/server.go", Line:9, FunctionName:"main.handler", Cond:"", Tracepoint:false, Goroutine:false, Stacktrace:0, Variables:[]string(nil), LoadArgs:(*api.LoadConfig)(nil), LoadLocals:(*api.LoadConfig)(nil), HitCount:map[string]uint64{}, TotalHitCount:0x0}
  2. 2017/04/07 16:41:41 debugger.go:412: continuing

你尝试过使用nohup来运行你的服务器吗？

  1. nohup go run server.go &

Did you tried running your server using nohup?
