conditionalUpdate method

Future<HttpBody> conditionalUpdate(HttpBody request, String parent, String type, { String? $fields, })

If a resource is found with the identifier specified in the query parameters, updates the entire contents of that resource.

Implements the FHIR standard conditional update interaction, limited to searching by resource identifier. Search term for identifier should be in the pattern identifier=system|value or identifier=value - similar to the search method on resources with a specific identifier. If the search criteria identify more than one match, the request returns a 412 Precondition Failed error. If the search criteria identify zero matches, and the supplied resource body contains an id, and the FHIR store has enable_update_create set, creates the resource with the client-specified ID. It is strongly advised not to include or encode any sensitive data such as patient identifiers in client-specified resource IDs. Those IDs are part of the FHIR resource path recorded in Cloud Audit Logs and Pub/Sub notifications. Those IDs can also be contained in reference fields within other resources. If the search criteria identify zero matches, and the supplied resource body does not contain an id, the resource is created with a server-assigned ID as per the create method. The request body must contain a JSON-encoded FHIR resource, and the request headers must contain Content-Type: application/fhir+json. On success, the response body contains a JSON-encoded representation of the updated resource, including the server-assigned version ID. Errors generated by the FHIR store contain a JSON-encoded OperationOutcome resource describing the reason for the error. If the request cannot be mapped to a valid API method on a FHIR store, a generic GCP error might be returned instead. For samples that show how to call conditionalUpdate, see Conditionally updating a FHIR resource.

request - The metadata request object.

Request parameters:

parent - Required. The name of the FHIR store this resource belongs to. Value must have pattern ^projects/\[^/\]+/locations/\[^/\]+/datasets/\[^/\]+/fhirStores/\[^/\]+$.

type - Required. The FHIR resource type to update, such as Patient or Observation. For a complete list, see the FHIR Resource Index (DSTU2, STU3, R4). Must match the resource type in the provided content. Value must have pattern ^\[^/\]+$.

$fields - Selector specifying which fields to include in a partial response.

Completes with a HttpBody.

Completes with a commons.ApiRequestError if the API endpoint returned an error.

If the used http.Client completes with an error when making a REST call, this method will complete with the same error.

Implementation

async.Future<HttpBody> conditionalUpdate(
  HttpBody request,
  core.String parent,
  core.String type, {
  core.String? $fields,
}) async {
  final body_ = convert.json.encode(request);
  final queryParams_ = <core.String, core.List<core.String>>{
    if ($fields != null) 'fields': [$fields],
  };

  final url_ = 'v1/' +
      core.Uri.encodeFull('$parent') +
      '/fhir/' +
      core.Uri.encodeFull('$type');

  final response_ = await _requester.request(
    url_,
    'PUT',
    body: body_,
    queryParams: queryParams_,
  );
  return HttpBody.fromJson(response_ as core.Map<core.String, core.dynamic>);
