从 python 脚本上传文件到我的 Dropbox

Question

我想将我的 python 脚本中的文件自动上传到我的 Dropbox 帐户。我无论如何都找不到只用一个用户/通行证来做到这一点。我在 Dropbox SDK 中看到的一切都与具有用户交互的应用程序有关。我只想做这样的事情：

https://api-content.dropbox.com/1/files_put//?user=me&pass=blah

Answer 1

@Christina 的答案基于 Dropbox APP v1，现已弃用，将于 2017 年 6 月 28 日关闭。 （更多信息请参考here。）

APP v2 于 2015 年 11 月推出，更简单、更一致、更全面。

这里是APP v2的源代码。

#!/usr/bin/env python
# -*- coding: utf-8 -*-
import dropbox

class TransferData:
    def __init__(self, access_token):
        self.access_token = access_token

    def upload_file(self, file_from, file_to):
        """upload a file to Dropbox using API v2
        """
        dbx = dropbox.Dropbox(self.access_token)

        with open(file_from, 'rb') as f:
            dbx.files_upload(f.read(), file_to)

def main():
    access_token = '******'
    transferData = TransferData(access_token)

    file_from = 'test.txt'
    file_to = '/test_dropbox/test.txt'  # The full path to upload the file to, including the file name

    # API v2
    transferData.upload_file(file_from, file_to)

if __name__ == '__main__':
    main()

源代码托管在 GitHub 上，here。

重要提示：此答案已弃用，因为 Dropbox 现在使用 v2 API。
当前API版本解决方案见@SparkAndShine的回答

感谢@smarx 的上述回答！我只是想为其他试图这样做的人澄清一下。

1. 当然，请确保首先安装 Dropbox 模块 pip install dropbox。

2. 在“应用程序控制台”中以您自己的 Dropbox 帐户创建应用程序。 (https://www.dropbox.com/developers/apps)

3. 为了记录，我使用以下内容创建了我的应用程序：

   一个。应用类型为“Dropbox API APP”。

   b.数据访问类型为“文件和数据存储”

   c。文件夹访问权限为“我的应用需要访问 Dropbox 上已有的文件”。 （即：权限类型为“Full Dropbox”。）

4. 然后点击“生成访问令牌”按钮并剪切/粘贴到下面的python示例中，代替<auth_token>：

import dropbox

client = dropbox.client.DropboxClient(<auth_token>)
print 'linked account: ', client.account_info()

f = open('working-draft.txt', 'rb')
response = client.put_file('/magnum-opus.txt', f)
print 'uploaded: ', response

folder_metadata = client.metadata('/')
print 'metadata: ', folder_metadata

f, metadata = client.get_file_and_metadata('/magnum-opus.txt')
out = open('magnum-opus.txt', 'wb')
out.write(f.read())
out.close()
print metadata

Answer 3

这是我使用 API v2（和 Python 3）的方法。我想上传一个文件并为其创建一个共享链接，我可以通过电子邮件将其发送给用户。它基于 sparkandshine 的示例。注意我认为当前的 API 文档有一个小错误，sparkandshine 已经纠正了。

import pathlib
import dropbox
import re

# the source file
folder = pathlib.Path(".")    # located in this folder
filename = "test.txt"         # file name
filepath = folder / filename  # path object, defining the file

# target location in Dropbox
target = "/Temp/"              # the target folder
targetfile = target + filename   # the target path and file name

# Create a dropbox object using an API v2 key
d = dropbox.Dropbox(your_api_access_token)

# open the file and upload it
with filepath.open("rb") as f:
   # upload gives you metadata about the file
   # we want to overwite any previous version of the file
   meta = d.files_upload(f.read(), targetfile, mode=dropbox.files.WriteMode("overwrite"))

# create a shared link
link = d.sharing_create_shared_link(targetfile)

# url which can be shared
url = link.url

# link which directly downloads by replacing ?dl=0 with ?dl=1
dl_url = re.sub(r"\?dl\=0", "?dl=1", url)
print (dl_url)

import dropbox
access_token = '************************'
file_from = 'index.jpeg'  //local file path
file_to = '/Siva/index.jpeg'      // dropbox path
def upload_file(file_from, file_to):
    dbx = dropbox.Dropbox(access_token)
    f = open(file_from, 'rb')
    dbx.files_upload(f.read(), file_to)
upload_file(file_from,file_to)

Answer 5

对 Dropbox API 的调用进行身份验证的唯一方法是使用 OAuth，这涉及到用户授予您应用的权限。我们不允许第三方应用处理用户凭据（用户名和密码）。

如果这仅适用于您的帐户，请注意，您可以轻松地为自己的帐户获取 OAuth 令牌并使用它。见https://www.dropbox.com/developers/blog/94/generate-an-access-token-for-your-own-account。

如果这是针对其他用户的，他们需要通过浏览器对您的应用进行一次授权，您才能获得 OAuth 令牌。但是，一旦获得令牌，您就可以继续使用它，因此每个用户只需执行一次。

抱歉，如果我遗漏了某些内容，但您不能只为您的操作系统下载 Dropbox 应用程序，然后将文件（在 Windows 中）保存在：

C:\Users\<UserName>\Dropbox\<FileName>

我刚刚创建了一个 python 程序来保存一个文本文件，检查了我的保管箱，它保存得很好。

对于 Dropbox Business API，下面的 python 代码有助于将文件上传到 Dropbox。

def dropbox_file_upload(access_token,dropbox_file_path,local_file_name):
'''
The function upload file to dropbox.

    Parameters:
        access_token(str): Access token to authinticate dropbox
        dropbox_file_path(str): dropboth file path along with file name
        Eg: '/ab/Input/f_name.xlsx'
        local_file_name(str): local file name with path from where file needs to be uploaded
        Eg: 'f_name.xlsx' # if working directory
Returns:
    Boolean: 
        True on successful upload
        False on unsuccessful upload
'''
try:
    dbx = dropbox.DropboxTeam(access_token)
    # get the team member id for common user
    members = dbx.team_members_list()
    for i in range(0,len(members.members)):
        if members.members[i].profile.name.display_name == logged_in_user:
            member_id = members.members[i].profile.team_member_id
            break
    # connect to dropbox with member id
    dbx = dropbox.DropboxTeam(access_token).as_user(member_id)
    # upload local file to dropbox
    f = open(local_file_name, 'rb')
    dbx.files_upload(f.read(),dropbox_file_path)
    return True
except Exception as e:
    print(e)
    return False

这是在 windows 中使用 python 在 Dropbox 上上传 livevideo 的代码。 希望这会对你有所帮助。

import numpy as np
import cv2
import dropbox
import os
from glob import iglob


access_token = 'paste your access token here'   #paste your access token in-between ''
client = dropbox.client.DropboxClient(access_token)
print 'linked account: ', client.account_info()
PATH = ''

cap = cv2.VideoCapture(0)


# Define the codec and create VideoWriter object
fourcc = cv2.VideoWriter_fourcc(*'XVID')
out = cv2.VideoWriter('C:\python27\output1.avi',fourcc, 20.0, (640,480))

#here output1.avi is the filename in which your video which is captured from webcam is stored. and it resides in C:\python27 as per the path is given.

while(cap.isOpened()):
ret, frame = cap.read()
if ret==True:
#frame = cv2.flip(frame,0) #if u want to flip your video

# write the (unflipped or flipped) frame
out.write(frame)

cv2.imshow('frame',frame)
if cv2.waitKey(1) & 0xFF == ord('q'):
break
else:
break

# Release everything if job is finished
cap.release()
out.release()
cv2.destroyAllWindows()

for filename in iglob(os.path.join(PATH, 'C:/Python27/output1.avi')):
print filename
try:
f = open(filename, 'rb')
response = client.put_file('/livevideo1.avi', f)
print "uploaded:", response
f.close()
#os.remove(filename)
except Exception, e:
print 'Error %s' % e

这是在 windows 中使用 python 将现有视频上传到您的 Dropbox 帐户的代码。

希望这会对你有所帮助。

# Include the Dropbox SDK
import dropbox

# Get your app key and secret from the Dropbox developer website
app_key = 'paste your app-key here'
app_secret = 'paste your app-secret here'

flow = dropbox.client.DropboxOAuth2FlowNoRedirect(app_key, app_secret)

# Have the user sign in and authorize this token
authorize_url = flow.start()
print '1. Go to: ' + authorize_url
print '2. Click "Allow" (you might have to log in first)'
print '3. Copy the authorization code.'
code = raw_input("Enter the authorization code here: ").strip()

# This will fail if the user enters an invalid authorization code
access_token, user_id = flow.finish(code)

client = dropbox.client.DropboxClient(access_token)
print 'linked account: ', client.account_info()

f = open('give full path of the video which u want to upload on your dropbox account(ex: C:\python27\examples\video.avi)', 'rb')
response = client.put_file('/video1.avi', f) #video1.avi is the name in which your video is shown on your dropbox account. You can give any name here.
print 'uploaded: ', response

folder_metadata = client.metadata('/')
print 'metadata: ', folder_metadata

f, metadata = client.get_file_and_metadata('/video1.avi')
out = open('video1.avi', 'wb')
out.write(f.read())
out.close()
print metadata

现在上传图片，将使用相同的代码。

只写您要上传的图片文件名，例如： image.jpg 代替 video name 。还要更改 video1.avi 的名称，并为您上传的图像写入图像名称，其中您上传的图像将显示在您的 Dropbox 中，例如：image1.jpg。
