Functions

func CheckResponse 

func CheckResponse(r *http.Response) error

CheckResponse checks the API response for errors, and returns them if present. A response is considered an error if it has a status code outside the 200 range. API error responses are expected to have either no response body, or a JSON response body that maps to ErrorResponse. Any other response body will be silently ignored.

func WaitUntilStored 

func WaitUntilStored(ctx context.Context, c *Client, transferID string) (SIPID string, err error)

WaitUntilStored blocks until the AIP generated after a transfer is confirmed to be stored. The implementation is based on TransferService.Status and JobsService.List.

The retry gives up as soon as one of the following events occur: * The caller cancels the context. * The total retry period exceeds maxWait.

TODO: we may want to give up earlier in case of specific errors, e.g. if TransferService.Status returns errors repeatedly?

Example 
package main

import (
	"context"
	"fmt"
	"log"
	"net/http"
	"time"

	"github.com/artefactual-labs/enduro/internal/amclient"
)

func main() {
	ctx := context.Background()
	client := amclient.NewClient(http.DefaultClient, "http://127.0.0.1:62080/api", "test", "test")

	// Start transfer.
	ctxTimeout, cancel := context.WithTimeout(ctx, time.Hour*2)
	defer cancel()
	payload, _, err := client.Package.Create(ctxTimeout, &amclient.PackageCreateRequest{
		Name:             "images",
		Type:             "standard",
		Path:             "/home/archivematica/archivematica-sampledata/SampleTransfers/Images",
		ProcessingConfig: "automated",
	})
	if err != nil {
		log.Fatal("Package.Create failed: ", err)
	}

	// Wait until the AIP is stored.
	SIPID, err := amclient.WaitUntilStored(ctx, client, payload.ID)
	if err != nil || SIPID == "" {
		log.Fatal("WaitUntilStored failed: ", err)
	}

	fmt.Printf("Transfer stored successfully! AIP %s", SIPID)
}

Types

type Client 

type Client struct {

	// Base URL for API requests.
	BaseURL *url.URL

	// User agent for client
	UserAgent string

	// Authentication
	User string
	Key  string

	// Services used for communicating with the API
	Transfer         TransferService
	Ingest           IngestService
	ProcessingConfig ProcessingConfigService
	Package          PackageService
	Jobs             JobsService
	Task             TaskService

func New 

func New(httpClient *http.Client, bu, u, k string, opts ...ClientOpt) (*Client, error)

New returns a new Archivematica API client instance.

func NewClient

NewClient returns a new Archivematica API client.

func (*Client) Do 

func (c *Client) Do(ctx context.Context, req *http.Request, v interface{}) (*Response, error)

Do sends an API request and returns the API response. The API response is JSON decoded and stored in the value pointed to by v, or returned as an error if an API error has occurred. If v implements the io.Writer interface, the raw response will be written to v, without attempting to decode it.

func (*Client) NewRequest 

func (c *Client) NewRequest(ctx context.Context, method, urlStr string, body interface{}, opts ...RequestOpt) (*http.Request, error)

NewRequest creates an API request. A relative URL can be provided in urlStr, which will be resolved to the BaseURL of the Client. Relative URLS should always be specified without a preceding slash. If specified, the value pointed to by body is form encoded and included in as the request body.

func (*Client) NewRequestJSON 

func (c *Client) NewRequestJSON(ctx context.Context, method, urlStr string, body interface{}, opts ...RequestOpt) (*http.Request, error)
