http请求会自动重试吗?

我正在尝试使用GoLang将数据推送到apache服务器.假设我的apache服务器暂时停止了.然后，我的http请求将自动重试.我正在使用这句话

I am trying to push my data to apache server using GoLang. Suppose my apache server is temporarily stopped. Then will my http request retry automatically. I am using this statement

resp, err := http.DefaultClient.Do(req) if err != nil { return errors.Wrap(err, "http request error") }

我无法继续进行调查，因为我的死刑被卡在这里了.而且我反复出现此错误.

I am unable to proceed further coz what is think is my execution is stuck here. And I am repeatedly getting this error.

推荐答案

否，您将需要实现自己的重试方法，这是一个基本示例，可以使您有所了解:

No, you will need to implement your own retry method, this is a basic example that could give you an idea:

play.golang/p/_o5AgePDEXq

package main import ( "fmt" "io/ioutil" "log" "net/http" ) func main() { var ( err error response *http.Response retries int = 3 ) for retries > 0 { response, err = http.Get("non-existent") // response, err = http.Get("google/robots.txt") if err != nil { log.Println(err) retries -= 1 } else { break } } if response != nil { defer response.Body.Close() data, err := ioutil.ReadAll(response.Body) if err != nil { log.Fatal(err) } fmt.Printf("data = %s\n", data) } }
