var AfterRetryHandler = request.NamedHandler{Name: "core.AfterRetryHandler", Fn: func(r *request.Request) { if r.Retryable == nil { r.Retryable = aws.Bool(r.ShouldRetry(r)) } if r.WillRetry() { r.RetryDelay = r.RetryRules(r) r.Config.SleepDelay(r.RetryDelay) if r.IsErrorExpired() { r.Config.Credentials.Expire() } r.RetryCount++ r.Error = nil } }}
AfterRetryHandler performs final checks to determine if the request should be retried and how long to delay.
var BuildContentLengthHandler = request.NamedHandler{Name: "core.BuildContentLengthHandler", Fn: func(r *request.Request) { var length int64 if slength := r.HTTPRequest.Header.Get("Content-Length"); slength != "" { length, _ = strconv.ParseInt(slength, 10, 64) } else { switch body := r.Body.(type) { case nil: length = 0 case lener: length = int64(body.Len()) case io.Seeker: r.BodyStart, _ = body.Seek(0, 1) end, _ := body.Seek(0, 2) body.Seek(r.BodyStart, 0) length = end - r.BodyStart default: panic("Cannot get length of body, must provide `ContentLength`") } } if length > 0 { r.HTTPRequest.ContentLength = length r.HTTPRequest.Header.Set("Content-Length", fmt.Sprintf("%d", length)) } else { r.HTTPRequest.ContentLength = 0 r.HTTPRequest.Header.Del("Content-Length") } }}
BuildContentLengthHandler builds the content length of a request based on the body, or will use the HTTPRequest.Header's "Content-Length" if defined. If unable to determine request body length and no "Content-Length" was specified it will panic.
The Content-Length will only be aded to the request if the length of the body is greater than 0. If the body is empty or the current `Content-Length` header is <= 0, the header will also be stripped.
var SDKVersionUserAgentHandler = request.NamedHandler{ Name: "core.SDKVersionUserAgentHandler", Fn: request.MakeAddToUserAgentHandler(aws.SDKName, aws.SDKVersion, runtime.Version(), runtime.GOOS, runtime.GOARCH), }
SDKVersionUserAgentHandler is a request handler for adding the SDK Version to the user agent.
var SendHandler = request.NamedHandler{Name: "core.SendHandler", Fn: func(r *request.Request) { var err error r.HTTPResponse, err = r.Config.HTTPClient.Do(r.HTTPRequest) if err != nil { if r.HTTPResponse != nil { r.HTTPResponse.Body.Close() } if e, ok := err.(*url.Error); ok && e.Err != nil { if s := reStatusCode.FindStringSubmatch(e.Err.Error()); s != nil { code, _ := strconv.ParseInt(s[1], 10, 64) r.HTTPResponse = &http.Response{ StatusCode: int(code), Status: http.StatusText(int(code)), Body: ioutil.NopCloser(bytes.NewReader([]byte{})), } return } } if r.HTTPResponse == nil { r.HTTPResponse = &http.Response{ StatusCode: int(0), Status: http.StatusText(int(0)), Body: ioutil.NopCloser(bytes.NewReader([]byte{})), } } r.Error = awserr.New("RequestError", "send request failed", err) r.Retryable = aws.Bool(true) } }}
SendHandler is a request handler to send service request using HTTP client.
var ValidateEndpointHandler = request.NamedHandler{Name: "core.ValidateEndpointHandler", Fn: func(r *request.Request) { if r.ClientInfo.SigningRegion == "" && aws.StringValue(r.Config.Region) == "" { r.Error = aws.ErrMissingRegion } else if r.ClientInfo.Endpoint == "" { r.Error = aws.ErrMissingEndpoint } }}
ValidateEndpointHandler is a request handler to validate a request had the appropriate Region and Endpoint set. Will set r.Error if the endpoint or region is not valid.
var ValidateParametersHandler = request.NamedHandler{Name: "core.ValidateParametersHandler", Fn: func(r *request.Request) { if !r.ParamsFilled() { return } if v, ok := r.Params.(request.Validator); ok { if err := v.Validate(); err != nil { r.Error = err } } }}
ValidateParametersHandler is a request handler to validate the input parameters. Validating parameters only has meaning if done prior to the request being sent.
var ValidateResponseHandler = request.NamedHandler{Name: "core.ValidateResponseHandler", Fn: func(r *request.Request) { if r.HTTPResponse.StatusCode == 0 || r.HTTPResponse.StatusCode >= 300 { r.Error = awserr.New("UnknownError", "unknown error", nil) } }}
ValidateResponseHandler is a request handler to validate service response.
