问题描述
我目前正在努力寻找一种在 Go 中创建 HTTP 帖子时重用连接的方法.
I'm currently struggling to find a way to reuse connections when making HTTP posts in Go.
我已经创建了一个像这样的传输和客户端:
I've created a transport and client like so:
// Create a new transport and HTTP client
tr := &http.Transport{}
client := &http.Client{Transport: tr}
然后我将此客户端指针传递到一个 goroutine 中,该 goroutine 向同一个端点发送多个帖子,如下所示:
I'm then passing this client pointer into a goroutine which is making multiple posts to the same endpoint like so:
r, err := client.Post(url, "application/json", post)
查看 netstat 这似乎导致每个帖子都有一个新连接,从而导致大量并发连接被打开.
Looking at netstat this appears to be resulting in a new connection for every post resulting in a large number of concurrent connections being open.
在这种情况下重用连接的正确方法是什么?
What is the correct way to reuse connections in this case?
推荐答案
确保您阅读直到响应完成并调用 Close()
.
例如
res, _ := client.Do(req)
io.Copy(ioutil.Discard, res.Body)
res.Body.Close()
再次...要确保 http.Client
连接重用,请务必:
Again... To ensure http.Client
connection reuse be sure to:
- 阅读直到响应完成(即
ioutil.ReadAll(resp.Body)
) - 调用
Body.Close()
