Functions

func RequestRetryAll

func RequestRetryAll(retryFuncs ...RequestRetryFunc) func(resp *http.Response, o *odata.OData) (bool, error)

RequestRetryAll wraps multiple RequestRetryFuncs and calls them in turn, only returning true if all funcs return true

func RequestRetryAny

func RequestRetryAny(retryFuncs ...RequestRetryFunc) func(resp *http.Response, o *odata.OData) (bool, error)

RequestRetryAny wraps multiple RequestRetryFuncs and calls them in turn, returning true if any func returns true

func RetryOn404ConsistencyFailureFunc

func RetryOn404ConsistencyFailureFunc(resp *http.Response, _ *odata.OData) (bool, error)

RetryOn404ConsistencyFailureFunc can be used to retry a request when a 404 response is received

func RetryableErrorHandler

func RetryableErrorHandler(resp *http.Response, err error, _ int) (*http.Response, error)

RetryableErrorHandler simply returns the resp and err, this is needed to make the Do() method of retryablehttp client return early with the response body not drained.

Types

type BaseClient

type BaseClient interface {
	// Execute invokes a non-paginated API request and returns a populated *Response
	Execute(ctx context.Context, req *Request) (*Response, error)

	// ExecutePaged invokes a paginated API request, merges the results from all pages and returns a populated *Response with all results
	ExecutePaged(ctx context.Context, req *Request) (*Response, error)

	// NewRequest constructs a *Request that can be passed to Execute or ExecutePaged
	NewRequest(ctx context.Context, input RequestOptions) (*Request, error)
}

type Client

type Client struct {
	// BaseUri is the base endpoint for this API.
	BaseUri string

	// UserAgent is the HTTP user agent string to send in requests.
	UserAgent string

	// CorrelationId is a custom correlation ID which can be added to requests for tracing purposes
	CorrelationId string

	// Authorizer is anything that can provide an access token with which to authorize requests.
	Authorizer auth.Authorizer

	// AuthorizeRequest is an optional function to decorate a Request for authorization prior to being sent.
	// When nil, a standard Authorization header will be added using a bearer token as returned by the Token method
	// of the configured Authorizer. Define this function in order to customize the request authorization.
	AuthorizeRequest func(context.Context, *http.Request, auth.Authorizer) error

	// DisableRetries prevents the client from reattempting failed requests (which it does to work around eventual consistency issues).
	// This does not impact handling of retries related to rate limiting, which are always performed.
	DisableRetries bool

	// RequestMiddlewares is a slice of functions that are called in order before a request is sent
	RequestMiddlewares *[]RequestMiddleware

	// ResponseMiddlewares is a slice of functions that are called in order before a response is parsed and returned
	ResponseMiddlewares *[]ResponseMiddleware
}

Client is a base client to be used by API-specific clients. It satisfies the BaseClient interface.

func (*Client) ExecutePaged

func (c *Client) ExecutePaged(ctx context.Context, req *Request) (*Response, error)

ExecutePaged automatically pages through the results of Execute

func (*Client) NewRequest

func (c *Client) NewRequest(ctx context.Context, input RequestOptions) (*Request, error)

NewRequest configures a new *Request

type Headers

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

Headers is a representation of the HTTP headers to be sent with a Request

func (*Headers) Append

func (h *Headers) Append(key, value string)

Append sets a single header value

Headers returns an http.Headers map containing header values

func (*Headers) Merge added in v0.20230216.1112535

func (h *Headers) Merge(h2 Headers)

Merge copies the header values from h2, overwriting as necessary

type Options

type Options interface {
	// ToHeaders yields a custom Headers struct to be appended to the request
	ToHeaders() *Headers
