Types ¶

type AWSService ¶

type AWSService interface {
	// Queries the AWS service at a given method/path with the params and
	// returns an http.Response and error
	Query(method, path string, params map[string]string) (*http.Response, error)
	// Builds an error given an XML payload in the http.Response, can be used
	// to process an error if the status code is not 200 for example.
	BuildError(r *http.Response) error

func (*Attempt) HasNext ¶

func (a *Attempt) HasNext() bool

HasNext returns whether another attempt will be made if the current one fails. If it returns true, the following call to Next is guaranteed to return true.

func (*Attempt) Next ¶

func (a *Attempt) Next() bool

Next waits until it is time to perform the next attempt or returns false if it is time to stop trying.

type AttemptStrategy ¶

type AttemptStrategy struct {
	Total time.Duration // total duration of attempt.

GetAuth creates an Auth based on either passed in credentials, environment information or instance based role credentials.

func NewAuth ¶

func NewAuth(accessKey, secretKey, token string, expiration time.Time) *Auth

To be used with other APIs that return auth credentials such as STS

func SharedAuth ¶

func SharedAuth() (auth Auth, err error)

type Region struct {
	Name                    string // the canonical name of this region.
	EC2Endpoint             string
	S3Endpoint              string
	S3BucketEndpoint        string // Not needed by AWS S3. Use ${bucket} for bucket name.
	S3LocationConstraint    bool   // true if this region requires a LocationConstraint declaration.
	S3LowercaseBucket       bool   // true if the region requires bucket names to be lower case.
	SDBEndpoint             string
	SESEndpoint             string
	SNSEndpoint             string
	SQSEndpoint             string
	IAMEndpoint             string
	ELBEndpoint             string
	DynamoDBEndpoint        string
	CloudWatchServicepoint  ServiceInfo

See http://goo.gl/d8BP1 for more details.

type ResilientTransport ¶

type ResilientTransport struct {
	// Timeout is the maximum amount of time a dial will wait for
	// a connect to complete.
	//
	// The default is no timeout.
	//

Output:

func NewV4Signer ¶

func NewV4Signer(auth Auth, serviceName string, region Region) *V4Signer

Return a new instance of a V4Signer capable of signing AWS requests.

func (*V4Signer) Sign ¶

func (s *V4Signer) Sign(req *http.Request)

Sign a request according to the AWS Signature Version 4 Signing Process. (http://goo.gl/u1OWZz)

The signed request will include an "x-amz-date" header with a current timestamp if a valid "x-amz-date" or "date" header was not available in the original request. In addition, AWS Signature Version 4 requires the "host" header to be a signed header, therefor the Sign method will manually set a "host" header from the request.Host.

The signed request will include a new "Authorization" header indicating that the request has been signed.

Any changes to the request after signing the request will invalidate the signature.
