)

func main() {
	clnt := mlablocatev2.NewClient(http.DefaultClient, log.Log, "miniooni/0.1.0-dev")
	results, err := clnt.QueryNDT7(context.Background())
	if err != nil {
		log.WithError(err).Fatal("clnt.QueryNDT7 failed")
	}
	fmt.Printf("%+v\n", results)
}

Types

type Client

type Client struct {
	// HTTPClient is the MANDATORY http client to use
	HTTPClient model.HTTPClient

	// Hostname is the MANDATORY hostname of the mlablocate API.
	Hostname string

	// Logger is the MANDATORY logger to use.
	Logger model.DebugLogger

	// Scheme is the MANDATORY scheme to use (http or https).
	Scheme string

	// UserAgent is the MANDATORY user-agent to use.
	UserAgent string
}

Client is a client for v2 of the locate services. Please use the NewClient factory to construct a new instance of client, otherwise you MUST fill all the fields marked as MANDATORY.

func NewClient

func NewClient(httpClient model.HTTPClient, logger model.DebugLogger, userAgent string) Client

NewClient creates a client for v2 of the locate services.

func (Client) QueryNDT7

func (c Client) QueryNDT7(ctx context.Context) ([]NDT7Result, error)

QueryNDT7 performs a v2 locate services query for ndt7.

type NDT7Result

type NDT7Result struct {
	// Hostname is an informative field containing the hostname
	// to which you're connected. Because there are access tokens,
	// you cannot use this field directly.
	Hostname string

	// Site is an informative field containing the site
	// to which the server belongs to.
	Site string

	// WSSDownloadURL is the WebSocket URL to be used for
	// performing a download over HTTPS. Note that the URL
	// typically includes the required access token.
	WSSDownloadURL string

	// WSSUploadURL is like WSSDownloadURL but for the upload.
	WSSUploadURL string
}

NDT7Result is the result of a v2 locate services query for ndt7.
