Functions

func DoPollForAsynchronous 

func DoPollForAsynchronous(delay time.Duration) autorest.SendDecorator

DoPollForAsynchronous returns a SendDecorator that polls if the http.Response is for an Azure long-running operation. It will delay between requests for the duration specified in the RetryAfter header or, if the header is absent, the passed delay. Polling may be canceled by closing the optional channel on the http.Request.

func ExtractClientID 

func ExtractClientID(resp *http.Response) string

ExtractClientID extracts the client identifier from the x-ms-client-request-id header set on the http.Request sent to the service (and returned in the http.Response)

func ExtractRequestID 

func ExtractRequestID(resp *http.Response) string

ExtractRequestID extracts the Azure server generated request identifier from the x-ms-request-id header.

func IsAzureError 

func IsAzureError(e error) bool

IsAzureError returns true if the passed error is an Azure Service error; false otherwise.

func SaveToken 

func SaveToken(path string, mode os.FileMode, token Token) error

SaveToken persists an oauth token at the given location on disk. It moves the new file into place so it can safely be used to replace an existing file that maybe accessed by multiple processes.

func WithClientID 

func WithClientID(uuid string) autorest.PrepareDecorator

WithClientID returns a PrepareDecorator that adds an HTTP extension header of x-ms-client-request-id whose value is passed, undecorated UUID (e.g., "0F39878C-5F76-4DB8-A25D-61D2C193C3CA").

Example

Use a Client Inspector to set the request identifier. 

uuid := "71FDB9F4-5E49-4C12-B266-DE7B4FD999A6"
req, _ := autorest.Prepare(&http.Request{},
	autorest.AsGet(),
	autorest.WithBaseURL("https://microsoft.com/a/b/c/"))

c := autorest.Client{Sender: mocks.NewSender()}
c.RequestInspector = WithReturningClientID(uuid)

autorest.SendWithSender(c, req)
fmt.Printf("Inspector added the %s header with the value %s\n",
	HeaderClientID, req.Header.Get(HeaderClientID))
fmt.Printf("Inspector added the %s header with the value %s\n",
	HeaderReturnClientID, req.Header.Get(HeaderReturnClientID))

Output:

Inspector added the x-ms-client-request-id header with the value 71FDB9F4-5E49-4C12-B266-DE7B4FD999A6
Inspector added the x-ms-return-client-request-id header with the value true

func WithErrorUnlessStatusCode 

func WithErrorUnlessStatusCode(codes ...int) autorest.RespondDecorator

WithErrorUnlessStatusCode returns a RespondDecorator that emits an azure.RequestError by reading the response body unless the response HTTP status code is among the set passed.

If there is a chance service may return responses other than the Azure error format and the response cannot be parsed into an error, a decoding error will be returned containing the response body. In any case, the Responder will return an error if the status code is not satisfied.

If this Responder returns an error, the response body will be replaced with an in-memory reader, which needs no further closing.

func WithReturnClientID 

func WithReturnClientID(b bool) autorest.PrepareDecorator

WithReturnClientID returns a PrepareDecorator that adds an HTTP extension header of x-ms-return-client-request-id whose boolean value indicates if the value of the x-ms-client-request-id header should be included in the http.Response.

func WithReturningClientID 

func WithReturningClientID(uuid string) autorest.PrepareDecorator

WithReturningClientID returns a PrepareDecorator that adds an HTTP extension header of x-ms-client-request-id whose value is the passed, undecorated UUID (e.g., "0F39878C-5F76-4DB8-A25D-61D2C193C3CA"). It also sets the x-ms-return-client-request-id header to true such that UUID accompanies the http.Response.
