Google Cloud Dialogflow V2 Client - Class DocumentsClient (1.0.1)

Reference documentation and code samples for the Google Cloud Dialogflow V2 Client class DocumentsClient.

Service Description: Service for managing knowledge Documents.

This class provides the ability to make remote calls to the backing service through method calls that map to API methods. Sample code to get started:

$documentsClient = new DocumentsClient();
try {
    $formattedParent = $documentsClient->knowledgeBaseName('[PROJECT]', '[KNOWLEDGE_BASE]');
    $document = new Document();
    $operationResponse = $documentsClient->createDocument($formattedParent, $document);
    $operationResponse->pollUntilComplete();
    if ($operationResponse->operationSucceeded()) {
        $result = $operationResponse->getResult();
    // doSomethingWith($result)
    } else {
        $error = $operationResponse->getError();
        // handleError($error)
    }
    // Alternatively:
    // start the operation, keep the operation name, and resume later
    $operationResponse = $documentsClient->createDocument($formattedParent, $document);
    $operationName = $operationResponse->getName();
    // ... do other work
    $newOperationResponse = $documentsClient->resumeOperation($operationName, 'createDocument');
    while (!$newOperationResponse->isDone()) {
        // ... do other work
        $newOperationResponse->reload();
    }
    if ($newOperationResponse->operationSucceeded()) {
        $result = $newOperationResponse->getResult();
    // doSomethingWith($result)
    } else {
        $error = $newOperationResponse->getError();
        // handleError($error)
    }
} finally {
    $documentsClient->close();
}

Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parseName method to extract the individual identifiers contained within formatted names that are returned by the API.

reloadDocument

Reloads the specified document from its specified source, content_uri or content. The previously loaded content of the document will be deleted.

Note: Even when the content of the document has not changed, there still may be side effects because of internal implementation changes.

This method is a long-running operation. The returned Operation type has the following method-specific fields:

metadata: KnowledgeOperationMetadata
response: Document

Note: The projects.agent.knowledgeBases.documents resource is deprecated; only use projects.knowledgeBases.documents.

Parameters
Name	Description
`name`	`string` Required. The name of the document to reload. Format: `projects/<Project ID>/locations/<Location ID>/knowledgeBases/<Knowledge Base ID>/documents/<Document ID>`
`optionalArgs`	`array` Optional.
`↳ contentUri`	`string` Optional. The path of gcs source file for reloading document content. For now, only gcs uri is supported. For documents stored in Google Cloud Storage, these URIs must have the form `gs://<bucket-name>/<object-name>`.
`↳ importGcsCustomMetadata`	`bool` Optional. Whether to import custom metadata from Google Cloud Storage. Only valid when the document source is Google Cloud Storage URI.
`↳ smartMessagingPartialUpdate`	`bool` Optional. When enabled, the reload request is to apply partial update to the smart messaging allowlist.
`↳ retrySettings`	`RetrySettings\|array` Retry settings to use for this call. Can be a {@see} object, or an associative array of retry settings parameters. See the documentation on {@see} for example usage.

Returns
