无论如何，关闭客户端请求在golang /杜松子酒？ [英] Is there anyway to close client request in golang/gin?

问题描述

使用杜松子酒。

有没有办法通知客户关闭请求连接，然后服务器处理程序可以做任何后台工作，而不让客户端等待连接？

  func测试（c * gin.Context）{
 c.String（200，ok）
 //关闭客户端请求，然后执行一些作业，例如同步数据远程服务器。 
 // 
} 
  

解决方案

是的，你可以这么做。通过简单地从处理程序返回。而你想做的后台工作，你应该把它放在一个新的goroutine上。

请注意，连接和/或请求可以放回池中，但这是无关紧要的，客户会看到服务请求结束。

类似这样的：

  func测试（c * gin.Context）{
 c.String（200，ok）
 //通过从此函数返回，响应将被发送到客户端
 //并且连接到客户端将被关闭
 
 //开始的goroutine将继续存在，当然还有：
 go func（）{
 //此函数将继续执行... 
}（）
}

Using gin framework.

Is there anyway to notify client to close request connection, then server handler can do any back-ground jobs without letting the clients to wait on the connection?

func Test(c *gin.Context) {
        c.String(200, "ok")
        // close client request, then do some jobs, for example sync data with remote server.
        //
}

解决方案

Yes, you can do that. By simply returning from the handler. And the background job you want to do, you should put that on a new goroutine.

Note that the connection and/or request may be put back into a pool, but that is irrelevant, the client will see that serving the request ended. You achieve what you want.

Something like this:

func Test(c *gin.Context) {
    c.String(200, "ok")
    // By returning from this function, response will be sent to the client
    // and the connection to the client will be closed

    // Started goroutine will live on, of course:
    go func() {
       // This function will continue to execute... 
    }()
}
