在Dropbox API中自動化OAuth - 點擊提交按鈕登錄

Question

我想通過官方的Dropbox API登錄到Dropbox並上傳文件到我的Dropbox。

代碼似乎沒有點擊提交按鈕才能登錄到Dropbox。代碼不會阻止它掛起或凍結。我沒有遇到錯誤，所以沒有回溯。

奇怪的是，當我註釋掉填寫電子郵件或密碼（或兩者）時，單擊提交按鈕的作品。

我不想手動訪問Dropbox身份驗證鏈接，然後單擊允許按鈕。所以我試圖通過使用工具（Splinter）讓我自動執行瀏覽器操作來自動執行該任務。

對於我的代碼我使用Splinter和瀏覽器類型我使用PhantomJS

下面的代碼：

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 

有沒有人有什麼錯誤的想法，我怎麼能解決它？

謝謝。

我點擊使用time.sleep(5)之前暫停工作5秒鐘。

這裏的工作代碼：

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() 

if __name__ == "__main__": 
    phantomjsOAuth()
