如何在Google Drive API v3中将XLSX转换为表格

问题描述

我想将我的代码上传到Google云端硬盘时，将xlsx文件自动转换为Google电子表格。然而，虽然转换成功的csv文件，我得到：

 < HttpError 400请求https：// www时。 googleapis.com/upload/drive/v3/files?uploadType=resumable&alt=json返回了错误的请求> 
  

当试图上传xlsx时。

这里是我的代码：

  def upload_service（filepath，name =，description =，fileID =，parentID =）：
使用资源（服务）对象上传文件到驱动器。
 
 if service ==：authenticate_service（）
 
 if name ==：
 name = str（os.path.basename（filepath）.split（os.extsep）[0]）＃从文件路径获取
 
 extension = str（os.path.basename（filepath）.split（os.extsep）[1]）lower（）
 
 if extension ==csv：＃CSV 
 mime_type =text / csv
 [xls，xlsx]中的elif扩展名：#EXCEL 
 mime_type =application / ms-excel
 else：
 return 
 $ b $ media_body = MediaFileUpload（filepath，mimetype = mime_type，resumable = True）
 
如果parentID ==：
 meta = dict（name = name，mimeType =application / vnd.google-apps.spreadsheet，desc ription = description）
 else：
 meta = dict（name = name，mimeType =application / vnd.google-apps.spreadsheet，description = description，parents = [parentID]）
 
 if fileID ==：＃CREATE $ b $ upload = service.files（）。create（
 body = meta，
 media_body = media_body）.execute（）
 else：＃REPLACE 
 upload = service.files（）。update（
 body = meta，
 media_body = media_body，
 fileId = fileID）.execute（）
 
 print（\ nFINISHED UPLOADING）
  

如何在v3中执行此操作？它非常清楚如何在v2中做到这一点，但不是在更新的API中。

解决方案

在APIv3中，您需要指定一个非常特定的 MIME类型，以便进行转换。

在，您会注意到支持的转化可以在关于资源的 importFormats 数组。使用

GET https://www.googleapis.com获取 importFormats 列表/ drive / v3 / about？fields = importFormats& key = {YOUR_API_KEY}

或转到并输入 importFormats

您会在响应中注意到：

 application / vnd.ms-excel：[
application / vnd.google-apps.spreadsheet
] 
  

在您的代码中，使用：

  elif extension in [xls，xlsx]：＃EXCEL 
 mime_type =application / vnd.ms-excel
  pre> 
 
 
（注意额外的 vnd。），它应该很好运作！
 
I want to convert xlsx files automatically to Google spreadsheets when I upload them with my code to Google Drive. However, while the conversion works successfully for csv files, I get:
<HttpError 400 when requesting https://www.googleapis.com/upload/drive/v3/files?uploadType=resumable&alt=json returned "Bad Request">
when trying to upload xlsx.
Here is my code:
def upload_service(filepath, name="", description="", fileID="", parentID=""):
    """ Uses a Resource (service) object to upload a file to drive. """

    if service == "": authenticate_service()

    if name == "":
        name = str(os.path.basename(filepath).split(os.extsep)[0])   # Get from filepath

    extension = str(os.path.basename(filepath).split(os.extsep)[1]).lower()

    if extension == "csv":                  # CSV
        mime_type = "text/csv"
    elif extension in ["xls", "xlsx"]:      # EXCEL
        mime_type = "application/ms-excel"
    else:
        return

    media_body = MediaFileUpload(filepath, mimetype=mime_type, resumable=True)

    if parentID == "":
        meta = dict(name=name, mimeType="application/vnd.google-apps.spreadsheet", description=description)
    else:
        meta = dict(name=name, mimeType="application/vnd.google-apps.spreadsheet", description=description, parents=[parentID])

    if fileID == "":   # CREATE
        upload = service.files().create(
                                    body=meta,
                                    media_body=media_body).execute()
    else:   # REPLACE
        upload = service.files().update(
                                body=meta,
                                media_body=media_body,
                                fileId=fileID).execute()

    print ("\nFINISHED UPLOADING")
How can I do this in v3? It's very clear how to do it in v2, but not in the updated API.
 解决方案 
In APIv3, you need to specify a very specific MIME Type for the conversion to occur. 
At https://developers.google.com/drive/v3/web/manage-uploads#importing_to_google_docs_types_wzxhzdk8wzxhzdk9, you'll notice the statement "The supported conversions are available dynamically in the About resource's importFormats array". Get the importFormats list using either
GET https://www.googleapis.com/drive/v3/about?fields=importFormats&key={YOUR_API_KEY}
or by going to https://developers.google.com/drive/v3/reference/about/get#try-it and entering importFormats
You'll notice in the response:
"application/vnd.ms-excel": [
   "application/vnd.google-apps.spreadsheet"
]
In your code, use:
elif extension in ["xls", "xlsx"]:      # EXCEL
    mime_type = "application/vnd.ms-excel"
(notice the additional vnd.)and it should work well!
