Methods
| Method | Modifiers | Return Type | Description |
|---|---|---|---|
| documentPostCreateCallback(documentId, creationToken) | optional |
Promise<void> | A callback triggered directly after creating the document. In this callback the client has the opportunity, to verify against an authorization service, if the user who claims to create the document is the same user who created it. |
| fetchOrdererToken(tenantId, documentId, refresh) | Promise<ITokenResponse> | Fetches the orderer token from host. | |
| fetchStorageToken(tenantId, documentId, refresh) | Promise<ITokenResponse> | Fetches the storage token from host. |
Method Details
documentPostCreateCallback
A callback triggered directly after creating the document. In this callback the client has the opportunity, to verify against an authorization service, if the user who claims to create the document is the same user who created it.
Signature
documentPostCreateCallback?(documentId: string, creationToken: string): Promise<void>;
Remarks
Notes: * Using the callback may have performance impact on the document creation process. * Any exceptions thrown in the callback would fail the creation workflow (see createContainer(createNewSummary, resolvedUrl, logger, clientIsSummarizer) for more details).
Parameters
