Functions

func HasStatusCode

func HasStatusCode(resp *http.Response, statusCodes ...int) bool

HasStatusCode returns true if the Response's status code is one of the specified values. Exported as runtime.HasStatusCode().

func NewResponseError

func NewResponseError(resp *http.Response) error

NewResponseError creates a new *ResponseError from the provided HTTP response. Exported as runtime.NewResponseError().

func NopCloser

func NopCloser(rs io.ReadSeeker) io.ReadSeekCloser

NopCloser returns a ReadSeekCloser with a no-op close method wrapping the provided io.ReadSeeker. Exported as streaming.NopCloser().

Types

type AccessToken

type AccessToken struct {
	Token     string
	ExpiresOn time.Time
}

AccessToken represents an Azure service bearer access token with expiry information. Exported as azcore.AccessToken.

type Pipeline

type Pipeline struct {
	// contains filtered or unexported fields
}

Pipeline represents a primitive for sending HTTP requests and receiving responses. Its behavior can be extended by specifying policies during construction. Exported as runtime.Pipeline.

func NewPipeline

func NewPipeline(transport Transporter, policies ...Policy) Pipeline

NewPipeline creates a new Pipeline object from the specified Policies. Not directly exported, but used as part of runtime.NewPipeline().

func (Pipeline) Do

func (p Pipeline) Do(req *Request) (*http.Response, error)

Do is called for each and every HTTP request. It passes the request through all the Policy objects (which can transform the Request's URL/query parameters/headers) and ultimately sends the transformed HTTP request over the network.

type Policy

type Policy interface {
	// Do applies the policy to the specified Request.  When implementing a Policy, mutate the
	// request before calling req.Next() to move on to the next policy, and respond to the result
	// before returning to the caller.
	Do(req *Request) (*http.Response, error)
}

Policy represents an extensibility point for the Pipeline that can mutate the specified Request and react to the received Response. Exported as policy.Policy.

type PolicyFunc

type PolicyFunc func(*Request) (*http.Response, error)

PolicyFunc is a type that implements the Policy interface. Use this type when implementing a stateless policy as a first-class function.

func (PolicyFunc) Do

func (pf PolicyFunc) Do(req *Request) (*http.Response, error)

Do implements the Policy interface on policyFunc.

type Request

type Request struct {
	// contains filtered or unexported fields
}

Request is an abstraction over the creation of an HTTP request as it passes through the pipeline. Don't use this type directly, use NewRequest() instead. Exported as policy.Request.

func NewRequest

func NewRequest(ctx context.Context, httpMethod string, endpoint string) (*Request, error)

NewRequest creates a new Request with the specified input. Exported as runtime.NewRequest().

func (*Request) Body

func (req *Request) Body() io.ReadSeekCloser

Body returns the original body specified when the Request was created.

func (*Request) Clone

func (req *Request) Clone(ctx context.Context) *Request

Clone returns a deep copy of the request with its context changed to ctx.

func (*Request) Close

func (req *Request) Close() error

Close closes the request body.

func (*Request) Next

func (req *Request) Next() (*http.Response, error)

Next calls the next policy in the pipeline. If there are no more policies, nil and an error are returned. This method is intended to be called from pipeline policies. To send a request through a pipeline call Pipeline.Do().

func (*Request) OperationValue

func (req *Request) OperationValue(value interface{}) bool

OperationValue looks for a value set by SetOperationValue().

func (*Request) Raw

func (req *Request) Raw() *http.Request

Raw returns the underlying HTTP request.

func (*Request) RewindBody

func (req *Request) RewindBody() error

RewindBody seeks the request's Body stream back to the beginning so it can be resent when retrying an operation.

func (*Request) SetBody

func (req *Request) SetBody(body io.ReadSeekCloser, contentType string) error

SetBody sets the specified ReadSeekCloser as the HTTP request body, and sets Content-Type and Content-Length accordingly. If the ReadSeekCloser is nil or empty, Content-Length won't be set. If contentType is "", Content-Type won't be set. Use streaming.NopCloser to turn an io.ReadSeeker into an io.ReadSeekCloser.

func (*Request) SetOperationValue

func (req *Request) SetOperationValue(value interface{})

SetOperationValue adds/changes a mutable key/value associated with a single operation.

type ResponseError

type ResponseError struct {
	// ErrorCode is the error code returned by the resource provider if available.
	ErrorCode string

	// StatusCode is the HTTP status code as defined in https://pkg.go.dev/net/http#pkg-constants.
	StatusCode int

	// RawResponse is the underlying HTTP response.
	RawResponse *http.Response
}

ResponseError is returned when a request is made to a service and the service returns a non-success HTTP status code. Use errors.As() to access this type in the error chain. Exported as azcore.ResponseError.

func (*ResponseError) Error

func (e *ResponseError) Error() string

Error implements the error interface for type ResponseError. Note that the message contents are not contractual and can change over time.

type TokenCredential

type TokenCredential interface {
	// GetToken requests an access token for the specified set of scopes.
	GetToken(ctx context.Context, options TokenRequestOptions) (AccessToken, error)
}

TokenCredential represents a credential capable of providing an OAuth token. Exported as azcore.TokenCredential.

type TokenRequestOptions

type TokenRequestOptions struct {
	// Scopes contains the list of permission scopes required for the token.
	Scopes []string

	// TenantID identifies the tenant from which to request the token. azidentity credentials authenticate in
	// their configured default tenants when this field isn't set.
	TenantID string
}

TokenRequestOptions contain specific parameter that may be used by credentials types when attempting to get a token. Exported as policy.TokenRequestOptions.

type Transporter

type Transporter interface {
	// Do sends the HTTP request and returns the HTTP response or error.
	Do(req *http.Request) (*http.Response, error)
}

Transporter represents an HTTP pipeline transport used to send HTTP requests and receive responses. Exported as policy.Transporter.
