I am trying to understand Context by reading https://blog.golang.org/context
the code in https://blog.golang.org/context/google/google.go uses transport. CancelRequest Since http.Request now (I am using go 1.7.3) has context support now, I think the code can be simpler now. This is my version of Search: https://play.golang.org/p/EaHrbogwM9 // Search sends query to Google search and returns the results. func Search(ctx context.Context, query string) (Results, error) { // Prepare the Google Search API request. req, err := http.NewRequest("GET", "https://ajax.googleapis.com/ajax/services/search/web?v=1.0";, nil) if err != nil { return nil, err } q := req.URL.Query() q.Set("q", query) // If ctx is carrying the user IP address, forward it to the server. // Google APIs use the user IP to distinguish server-initiated requests // from end-user requests. if userIP, ok := userip.FromContext(ctx); ok { q.Set("userip", userIP.String()) } req.URL.RawQuery = q.Encode() // Issue the HTTP request and handle the response. The httpDo function // cancels the request if ctx.Done is closed. var results Results client := &http.Client{} req = req.WithContext(ctx) resp, err := client.Do(req) if err != nil { return nil, err } defer resp.Body.Close() // Parse the JSON search result. // https://developers.google.com/web-search/docs/#fonje var data struct { ResponseData struct { Results []struct { TitleNoFormatting string URL string } } } if err := json.NewDecoder(resp.Body).Decode(&data); err != nil { return nil, err } for _, res := range data.ResponseData.Results { results = append(results, Result{Title: res.TitleNoFormatting, URL: res.URL}) } return results, nil } But it does not work correctly, first search after `go run server.go` curl 'http://localhost:8080/search?q=golang&timeout=1s' will give `context deadline exceeded` but after that repeated searches will not return context deadline. what's wrong? -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
