php - 如何使用 google docs api php 插入文本

Question

我正在尝试使用 Google Docs Api 创建文档的副本，然后通过在其中插入文本来编辑该副本。所以，我查看了文档，似乎完全按照它所说的方式实现了它。

        ?>

这是定义 GoogleDrive::getClient 的地方，以防万一

class GoogleDrive
{
    private static $AUTH_CODE;

    public static function setAuthCode($desiredCode)
    {
        self::$AUTH_CODE = $desiredCode;
    }
    public static function getClient($credentialsPath, $callbackScript)
    {        
        $client = new Google_Client();
        $client->setApplicationName('MyApp');
        $client->setScopes(Google_Service_Drive::DRIVE);
        $client->setAuthConfig($credentialsPath);
        $client->setAccessType('online');
        $client->setPrompt('select_account consent');


        $desiredVariable = self::$AUTH_CODE;
        if($desiredVariable != null)
        {
            $accessToken = $client->fetchAccessTokenWithAuthCode($desiredVariable);
            $client->setAccessToken($accessToken);

            return $client;
        }

        // Load previously authorized token from a file, if it exists.
        // The file token.json stores the user's access and refresh tokens, and is
        // created automatically when the authorization flow completes for the first
        // time.
        $tokenPath = 'token.json';
        if (file_exists($tokenPath)) {
            $accessToken = json_decode(file_get_contents($tokenPath), true);
            $client->setAccessToken($accessToken);
        }

        // If there is no previous token or it's expired.
        if ($client->isAccessTokenExpired()) {
            // Refresh the token if possible, else fetch a new one.
            if ($client->getRefreshToken()) {
                $client->fetchAccessTokenWithRefreshToken($client->getRefreshToken());
            } else {
                // Request authorization from the user.
                $authUrl = $client->createAuthUrl();
                $client->setRedirectUri($callbackScript);
                redirect($authUrl);

                // Exchange authorization code for an access token.
                $accessToken = $client->fetchAccessTokenWithAuthCode($authCode);
                $client->setAccessToken($accessToken);

                // Check to see if there was an error.
                if (array_key_exists('error', $accessToken)) {
                    throw new Exception(join(', ', $accessToken));
                }
            }
            // Save the token to a file.
            if (!file_exists(dirname($tokenPath))) {
                mkdir(dirname($tokenPath), 0700, true);
            }
            file_put_contents($tokenPath, json_encode($client->getAccessToken()));
        }
        return $client;

    }

}

但是，当我运行以前的代码时，出现此错误。

"{
  "error": {
    "code": 400,
    "message": "This operation is not supported for this document",
    "errors": [
      {
        "message": "This operation is not supported for this document",
        "domain": "global",
        "reason": "failedPrecondition"
      }
    ],
    "status": "FAILED_PRECONDITION"
  }
}
"

任何帮助或方向将不胜感激。

编辑 1:我已更改脚本以反射(reflect) Tanaike 的解决方案

Answer 1

我相信你的情况和目标如下。

您已经能够使用 Google Docs API。

a copy of a document的脚本工作。

您想删除问题中的错误。

为此，这个修改怎么样？

从:

$desiredRequests = new Google_Service_Docs_Request(array(
    'insertText' => array(
    'text' => 'Hello world!',
    'location' => array(
    'index' => 25))));

在您的脚本中，当 $batchUpdateRequests被检索，变成如下。

{"requests":{"createNamedRangeType":{},"createNamedRangeDataType":{},"createParagraphBulletsType":{},"createParagraphBulletsDataType":{},"deleteContentRangeType":{},"deleteContentRangeDataType":{},"deleteNamedRangeType":{},"deleteNamedRangeDataType":{},"deleteParagraphBulletsType":{},"deleteParagraphBulletsDataType":{},"deletePositionedObjectType":{},"deletePositionedObjectDataType":{},"deleteTableColumnType":{},"deleteTableColumnDataType":{},"deleteTableRowType":{},"deleteTableRowDataType":{},"insertInlineImageType":{},"insertInlineImageDataType":{},"insertTableRowType":{},"insertTableRowDataType":{},"insertTextType":{},"insertTextDataType":{},"replaceAllTextType":{},"replaceAllTextDataType":{},"updateParagraphStyleType":{},"updateParagraphStyleDataType":{},"updateTextStyleType":{},"updateTextStyleDataType":{},"internal_gapi_mappings":{},"modelData":{},"processed":{},"insertText":{}}}

我认为这就是你的问题的原因。

到:

$desiredRequests = array(new Google_Service_Docs_Request(array(
    'insertText' => array(
    'text' => 'Hello world!',
    'location' => array(
    'index' => 25)))));

在这个修改后的脚本中，当 $batchUpdateRequests被检索，变成如下。

{"requests":[{"insertText":{"text":"Hello world!","location":{"index":25,"segmentId":null}}}]}

在这个请求正文中，我可以确认它有效。

笔记:

如果出现类似 Invalid requests[0].insertText: Index 25 must be less than the end index of the referenced segment 的错误发生，请修改'index' => 25至 'index' => 1 .
