我正在尝试将 PDF 转换为任何允许的格式，但在上传 pdf 文件后响应不包含 exportLinks。

我已经尝试了很多方法来获取exportLinks。其他文档格式可以上传导出成功。我使用了 developer.google.com 的代码。

media_body = MediaFileUpload(filename, mimetype=mime_type, resumable=False)
body = {'title': title,
        'description': description,
        'mimeType': mime_type,
        }
# Set the parent folder.
if parent_id:
    body['parents'] = [{'id': parent_id}]

try:
    request = service.files().insert(body=body, media_body=media_body)
    #request.uri = "%s&convert=true&ocr=true" % request.uri
    #request.uri = "%s&convert=true" % request.uri
    request.uri = "https://www.googleapis.com/upload/drive/v2/files?uploadType=multipart&alt=json&convert=true"
    logger.debug("Request: %s", request.uri)
    file_obj = request.execute()
    # Uncomment the following line to print the File ID
    # print 'File ID: %s' % file_obj['id']
    import json
    logger.debug('Get file result: %s' % json.dumps(file_obj, indent=4))
    return file_obj

...
export_links = source_file.get('exportLinks')
if not export_links:
    logger.debug('Warning: exportLinks does not exist')

为什么 PDF 上传的响应中没有 exportLinks？

请 Google 团队同意可以通过 Drive API 上传和导出 PDF。

谢谢

[UPD] 这是 Httplib2 的请求转储。正如我所见，查询已根据手册正确设置。

Here is a downloadLink in the response: "downloadUrl": " https://doc-0c-2c-docs.googleusercontent.com/docs/securesc/2sgoib42bclb5coaj85g5574fd2b65bn/2lnqk989jdaepp4b8igdco1j8fu7m9l3/1373040000000/00639208221381605991/00639208221381605991/0By108D1dgCDkX0NFOXV0V2pNd2s?h=16653014193614665626&e=download&gd =真“，

不幸的是，Google Drive 不提供通过 Google Drive API 转换 PDF 文件的功能。

只有 Google 原生文档（Google Docs/Sheets/Slides/Drawings）exportLinks允许以多种导出格式下载 Google 文档。所有其他文件 - 基本上是常规文件，例如 PDF、图像等...... - 有一个downloadUrl替代品，它允许您以原始格式下载文件本身。
