在Dropbox API中自动执行OAuth-单击提交按钮登录

Question

我正在尝试通过官方Dropbox API登录Dropbox，并将文件上传到我的Dropbox。

代码似乎没有点击提交按钮来登录Dropbox。代码不会停止它只是挂起或冻结。我没有得到错误，所以没有回溯。

奇怪的是，当我对电子邮件或密码（或两者）的填写进行评论时，点击提交按钮就可以了。

我不想手动访问Dropbox身份验证链接并单击"允许"按钮。因此，我试图通过使用一个工具（Splinter）来自动化这项任务，让我自动化浏览器操作。

对于我的代码，我使用Splinter，作为浏览器类型，我使用PhantomJS

这是代码：

from splinter import *
from dropbox import client, rest, session
# Initiate Dropbox API
APP_KEY = '###'
APP_SECRET = '###'
ACCESS_TYPE = 'dropbox'
sess = session.DropboxSession(APP_KEY, APP_SECRET, ACCESS_TYPE)
emailDropbox = '###'
passwordDropbox = '###'
request_token = sess.obtain_request_token()
urlDropbox = sess.build_authorize_url(request_token)
# Start Splinter login code
# Assumes you are not logged in to Dropbox
# Target url
print 'Target url: ', urlDropbox
browser = Browser('phantomjs')
print 'Starting browser'
print 'Visiting url'
browser.visit(urlDropbox)
# Email form
print 'Is the email form present? ', browser.is_element_present_by_id('login_email')
print 'Fill email form'
browser.find_by_id('login_email').first.fill(emailDropbox)
# Password form
print 'Is the password form present? ', browser.is_element_present_by_id('login_password')
print 'Fill password form'
browser.find_by_id('login_password').first.fill(passwordDropbox)
# Login submit button
print 'Is the submit button present?', browser.is_element_present_by_name('login_submit_dummy')
# Click submit button
print 'Attempting to click the submit button in order to login'
browser.find_by_name('login_submit_dummy').first.click()
print 'Submit button successfully clicked'
# Allow connection with Dropbox
print 'Is the "Allow" button present?', browser.is_element_present_by_id('allow_access')
browser.find_by_id('allow_access').click()
print 'The "Allow" button is successfully clicked'
# Quit the browser
browser.quit()
# The rest of the Dropbox code
# This will fail if the user didn't visit the above URL and hit 'Allow'
access_token = sess.obtain_access_token(request_token)
client = client.DropboxClient(sess)
print "linked account:", client.account_info()
f = open('working-draft.txt')
response = client.put_file('/magnum-opus.txt', f)
print "uploaded:", response

有人知道出了什么问题吗？我该怎么解决？

谢谢。

在使用time.sleep(5)单击之前，我暂停了5秒钟。

这是工作代码：

from splinter import *
from dropbox import rest, session
from dropbox import client as dbclient
import time
# Dropbox API
APP_KEY = '###'
APP_SECRET = '###'
ACCESS_TYPE = 'dropbox'
sess = session.DropboxSession(APP_KEY, APP_SECRET, ACCESS_TYPE)
emailDropbox = '###'
passwordDropbox = '###'
request_token = sess.obtain_request_token()
urlDropbox = sess.build_authorize_url(request_token)
def phantomjsOAuth():
    # Target url
    print 'Target url: ', urlDropbox
    browser = Browser('phantomjs')
    print 'Starting phantomjs browser'
    print 'Visiting url'
    browser.visit(urlDropbox)
    # Email form
    print 'Is the email form present? ', browser.is_element_present_by_id('login_email')
    print 'Filling email form'
    browser.find_by_id('email-field').first.find_by_id('login_email').first.fill(emailDropbox)
    print 'Email form successfully filled'
    # Password form
    print 'Is the password form present? ', browser.is_element_present_by_id('login_password')
    print 'Filling password form'
    browser.find_by_id('login_password').first.fill(passwordDropbox)
    print 'Password form successfully filled'
    # Find login submit button
    print 'Is the "Submit" button present?', browser.is_element_present_by_name('login_submit_dummy')
    submitButton = browser.is_element_present_by_name('login_submit_dummy')
    if submitButton == True:
        print 'Pausing for 5 seconds to avoid clicking errors'
        time.sleep(5)
        print 'Attempting to click the "Submit" button in order to login'
        browser.find_by_name('login_submit_dummy').first.click()
        print '"Submit" button successfully clicked'
        # Allow connection with Dropbox
        print 'Is the "Allow" button present?', browser.is_element_present_by_css('.freshbutton-blue')
        allowButton = browser.is_element_present_by_css('.freshbutton-blue')
        if allowButton == True:
            print 'The "Allow" button is present, attempting to click..'
            browser.find_by_css('.freshbutton-blue').click()
            print 'The "Allow" button is successfully clicked, access to Dropbox is granted.'
            browser.quit()
            dropboxCode()
        else:
            print 'The "Allow" button is not present, quitting.'
            browser.quit()
    else:
        print 'The "Submit" button was not present, quitting.'
        browser.quit()
def dropboxCode():
    # The rest of the Dropbox code
    # This will fail if 'Allow' wasn't clicked
    access_token = sess.obtain_access_token(request_token)
    client = dbclient.DropboxClient(sess)
    print "linked account:", client.account_info()
    f = open('dropbox_api_test_file.txt')
    response = client.put_file('/Python/Apps/###/Orders/dropbox_api_test_file.txt', f)
    print "uploaded:", response
    sess.unlink()
