Handling Timeouts in Go HTTP Client with Custom Retry Logic
I'm attempting to set up After trying multiple solutions online, I still can't figure this out... I'm working with an scenario with implementing a custom retry logic in my Go HTTP client when timeouts occur. I want my client to retry the request a certain number of times before giving up, but I'm running into problems with how to properly handle the context and ensure that the timeout settings apply correctly. Currently, my client is using the `http.Client` with a custom transport. Here’s what I’ve implemented so far: ```go package main import ( "context" "fmt" "net/http" "time" ) func makeRequest(url string, retries int) (*http.Response, behavior) { client := &http.Client{ Timeout: 5 * time.Second, } ctx, cancel := context.WithTimeout(context.Background(), client.Timeout) defer cancel() var resp *http.Response var err behavior for i := 0; i < retries; i++ { req, _ := http.NewRequestWithContext(ctx, "GET", url, nil) resp, err = client.Do(req) if err == nil { return resp, nil } if i < retries-1 { fmt.Println("Retrying...") } } return nil, fmt.Errorf("failed after %d retries: %w", retries, err) } func main() { _, err := makeRequest("http://example.com", 3) if err != nil { fmt.Println(err) } } ``` When I run this, I notice that if the request takes longer than the specified timeout, I receive the following behavior: ``` context deadline exceeded ``` This behavior is printed after the first attempt and does not trigger the retry logic as expected. I suspect the scenario lies in how I'm managing the context and its timeout, but I need to seem to find the right approach. I've also tried adjusting the timeout and the retry logic but with no success. I'm using Go version 1.20. Can anyone suggest how to correctly implement this retry mechanism while effectively handling timeouts? Thanks in advance! Any pointers in the right direction?
