2020年7月- Windows用户批处理文件解决方案

我想为windows用户添加一个简单的批处理文件解决方案，因为我只发现了linux解决方案，我花了几天时间来学习为windows创建解决方案的所有这些东西。因此，为了避免其他人可能需要它，这里是。

你需要的工具

wget for windows (5KB exe小程序，无需安装) 从这里下载。 https://eternallybored.org/misc/wget/ jrepl for windows (117KB的批处理程序，无需安装) 该工具类似于linux的sed工具。 从这里下载: https://www.dostips.com/forum/viewtopic.php?t=6044

假设

%filename% -你想下载的文件将被保存到的文件名。 %fileid% =谷歌文件id(前面已经解释过了)

批量代码下载小文件从谷歌驱动器

wget -O "%filename%" "https://docs.google.com/uc?export=download&id=%fileid%"        

批量代码下载大文件从谷歌驱动器

set cookieFile="cookie.txt"
set confirmFile="confirm.txt"
   
REM downlaod cooky and message with request for confirmation
wget --quiet --save-cookies "%cookieFile%" --keep-session-cookies --no-check-certificate "https://docs.google.com/uc?export=download&id=%fileid%" -O "%confirmFile%"
   
REM extract confirmation key from message saved in confirm file and keep in variable resVar
jrepl ".*confirm=([0-9A-Za-z_]+).*" "$1" /F "%confirmFile%" /A /rtn resVar
   
REM when jrepl writes to variable, it adds carriage return (CR) (0x0D) and a line feed (LF) (0x0A), so remove these two last characters
set confirmKey=%resVar:~0,-2%
   
REM download the file using cookie and confirmation key
wget --load-cookies "%cookieFile%" -O "%filename%" "https://docs.google.com/uc?export=download&id=%fileid%&confirm=%confirmKey%"
   
REM clear temporary files 
del %cookieFile%
del %confirmFile%

有一个更简单的方法。

从firefox/chrome扩展安装cliget/CURLWGET。

从浏览器下载文件。这将创建一个curl/wget链接，用于记住下载文件时使用的cookie和头文件。使用此命令从任何shell下载

我使用这个小脚本，只得到从谷歌驱动器复制的URL:

#!/bin/bash

name=`curl $1 |  grep -w \"name\" | sed 's/.*"name" content="//' | 
sed 's/".*//'`
id=`echo $1 | sed 's#.*/d/##; s#/view.*##'`
curl -L https://drive.google.com/uc?id=$id > $name
# or
# wget -O $name https://drive.google.com/uc?id=$id

警告:此功能已弃用。见下面评论中的警告。

看看这个问题:直接从谷歌驱动器使用谷歌驱动器API下载

基本上，你必须创建一个公共目录，并通过相对引用来访问你的文件

wget https://googledrive.com/host/LARGEPUBLICFOLDERID/index4phlat.tar.gz

或者，您可以使用这个脚本:https://github.com/circulosmeos/gdown.pl

我无法让Nanoix的perl脚本工作，或者我看到的其他curl示例，所以我开始自己用python研究api。这适用于小文件，但大文件阻塞了可用的ram，所以我找到了一些其他不错的分块代码，使用api的部分下载功能。要点: https://gist.github.com/csik/c4c90987224150e4a0b2

注意从API接口下载client_secret json文件到本地目录的部分。

源

$ cat gdrive_dl.py
from pydrive.auth import GoogleAuth  
from pydrive.drive import GoogleDrive    

"""API calls to download a very large google drive file.  The drive API only allows downloading to ram 
   (unlike, say, the Requests library's streaming option) so the files has to be partially downloaded
   and chunked.  Authentication requires a google api key, and a local download of client_secrets.json

def partial(total_byte_len, part_size_limit):
    s = []
    for p in range(0, total_byte_len, part_size_limit):
        last = min(total_byte_len - 1, p + part_size_limit - 1)
        s.append([p, last])
    return s

def GD_download_file(service, file_id):

  s = partial(total_size, 100000000) # I'm downloading BIG files, so 100M chunk size is fine for me

  originalFilename = drive_file.get('originalFilename')
  filename = './' + originalFilename
  if download_url:
      with open(filename, 'wb') as file:
        print "Bytes downloaded: "
        for bytes in s:
          headers = {"Range" : 'bytes=%s-%s' % (bytes[0], bytes[1])}
          resp, content = service._http.request(download_url, headers=headers)
          if resp.status == 206 :
                file.write(content)
                file.flush()
          else:
            print 'An error occurred: %s' % resp
            return None
          print str(bytes[1])+"..."
      return title, filename
  else:
    return None          


gauth = GoogleAuth()
gauth.CommandLineAuth() #requires cut and paste from a browser 

FILE_ID = 'SOMEID' #FileID is the simple file hash, like 0B1NzlxZ5RpdKS0NOS0x0Ym9kR0U

drive = GoogleDrive(gauth)
service = gauth.service
#file = drive.CreateFile({'id':FILE_ID})    # Use this to get file metadata
GD_download_file(service, FILE_ID) 

谷歌驱动器的默认行为是扫描文件的病毒，如果文件太大，它将提示用户，并通知他，该文件无法扫描。

目前我找到的唯一解决办法是在网络上共享文件并创建一个网络资源。

引用自谷歌驱动器帮助页面:

使用Drive，您可以使web资源-如HTML, CSS和Javascript文件-可作为网站查看。

使用Drive托管网页:

Open Drive at drive.google.com and select a file. Click the Share button at the top of the page. Click Advanced in the bottom right corner of the sharing box. Click Change.... Choose On - Public on the web and click Save. Before closing the sharing box, copy the document ID from the URL in the field below "Link to share". The document ID is a string of uppercase and lowercase letters and numbers between slashes in the URL. Share the URL that looks like "www.googledrive.com/host/[doc id] where [doc id] is replaced by the document ID you copied in step 6. Anyone can now view your webpage.

在这里找到:https://support.google.com/drive/answer/2881970?hl=en

例如，当你在谷歌驱动器上公开共享一个文件时，共享链接看起来是这样的:

https://drive.google.com/file/d/0B5IRsLTwEO6CVXFURmpQZ1Jxc0U/view?usp=sharing

然后复制文件id，创建googledrive.com链接，如下所示:

https://www.googledrive.com/host/0B5IRsLTwEO6CVXFURmpQZ1Jxc0U
