如何上传/转换 *.docx 为 google 文档? Google 云端硬盘 API v3

问题描述 投票:0回答:2

我在上传 microsoft/libre Office 文档以通过 Google Apps 进行编辑时遇到问题。对于电子表格,它可以正常工作,但对于文档则不然。

当我上传扩展名为 *.odt、*.docx 的文件时,我可以通过 Google 云端硬盘上的 google 查看器查看内容,但是当我单击文档顶部的“使用按钮进行编辑”时,Google 云端硬盘会创建一个具有相同内容的新文件,并且名称,但我在描述或任何能力中没有有关原始文件 ID 的信息。有什么想法如何上传准备在线编辑的文档吗?

  private async Task<string> UploadFileToGoogleDrive(string filePath, GoogleDriveFile file)
    {
        var fileData = new Google.Apis.Drive.v3.Data.File()
        {
            Name = file.Name,
            MimeType = file.MimeType

        };
        if (!String.IsNullOrEmpty(file.ParentId))
            fileData.Parents = new List<string>() { file.ParentId };

        FilesResource.CreateMediaUpload request;

        using (var stream = new FileStream(filePath, FileMode.Open))
        {
             request = _driveService.Files.Create(fileData, stream, StringEnum.GetStringValue(file.FileContent));
             request.Fields = "id";

             var uploadProgress = await request.UploadAsync();
             if (uploadProgress.Exception != null)
                 throw uploadProgress.Exception; 
        }
        return request.ResponseBody.Id;
    }

文件 MIME 类型 https://developers.google.com/drive/v3/web/manage-downloads

或者使用“importFormats”参数。 https://developers.google.com/drive/v3/reference/about/get

我也痛苦了很长一段时间。 为了让Google转换为我们需要的格式,我们在元数据的MimeType中指定它。您还需要在内容对象中的 MimeType 中指定当前文件格式。

只有 PHP 的示例

$fileMetadata = new \Google_Service_Drive_DriveFile([
    'name' => $this->_fileName,
    'parents' => array($directoryId),
    'mimeType' => 'application/vnd.google-apps.document'
]);

return $this->_service()->files->create($fileMetadata, [
    'data' => $document,
    'mimeType' => 'application/vnd.openxmlformats-officedocument.wordprocessingml.document',
    'uploadType' => 'multipart',
    'fields' => 'id',
]);

这是用 C# 编写的(我遵循了 https://developers.google.com/drive/api/v3/manage-uploads#import_to_google_docs_types_

中的示例)

您应该能够将代码放在文件流的 using 语句中

    using File = Google.Apis.Drive.v3.Data.File; // This obviously goes at the top of the file, alternatively you can fully qualify the File constructor, although I had ambiguity issued due to also `using System.IO` and the compiler not knowing which `File` I meant specifically. 

    ...

    var fileMetadata = new File() // please note this is Google.Apis.Drive.v3.Data.File;
    {
        Name = "New File Name I Want"
        MimeType = "application/vnd.google-apps.document"
    };

    var request = service.Files.Create(
        fileMetadata, 
        stream, 
        "application/vnd.openxmlformats-officedocument.wordprocessingml.document" // please note this is the mimeType of the source file not the tartget
    ); 
    request.Fields = "id";
    var result = await request.UploadAsync();

根据文档,可以使用更新操作而不是上传来执行此操作,但这会转换原始文件,并且原始文件将丢失。不幸的是,没有给出关于如何执行此操作的示例,并且 API 似乎对传入的内容非常挑剔。如果我弄清楚的话,将更新此答案以包括
