如何在 Python 中编辑 facebook post？

Question

我的 fb 页面上有一个 post，我需要每天更新几次 python 脚本中详细说明的数据。我尝试使用 Selenium，但是在保存 post 时它经常卡住，因此脚本也卡住了，所以我试图找到一种方法来在 python 本身内完成这项工作而不使用网络浏览器.

我想知道有没有办法使用 python 库（例如 Facepy 或类似库）来编辑 FB post？

我正在阅读graph API reference but there are no examples to learn from, but I guess first thing is to set up the login. On the facepy github页面上写的

note that Facepy does not do authentication with Facebook; it only consumes its API. To get an access token to consume the API on behalf of a user, use a suitable OAuth library for your platform

我尝试使用 BeautifulSoup

登录

from bs4 import BeautifulSoup
import requests
import re

def facebook_login(mail, pwd):
session = requests.Session()
r = session.get('https://www.facebook.com/', allow_redirects=False)
soup = BeautifulSoup(r.text)
action_url = soup.find('form', id='login_form')['action']
inputs = soup.find('form', id='login_form').findAll('input', {'type': ['hidden', 'submit']})
post_data = {input.get('name'): input.get('value')  for input in inputs}
post_data['email'] = mail
post_data['pass'] = pwd.upper()
scripts = soup.findAll('script')
scripts_string = '/n/'.join([script.text for script in scripts])
datr_search = re.search('\["_js_datr","([^"]*)"', scripts_string, re.DOTALL)
if datr_search:
    datr = datr_search.group(1)
    cookies = {'_js_datr' : datr}
else:
    return False
return session.post(action_url, data=post_data, cookies=cookies, allow_redirects=False)

facebook_login('email', 'psw')

但它给出了这个错误

action_url = soup.find('form', id='login_form')['action']
TypeError: 'NoneType' object is not subscriptable

我也试过 Mechanize

import mechanize

username = 'email'
password = 'psw'
url = 'http://facebook.com/login'

print("opening browser")
br = mechanize.Browser()
print("opening url...please wait")
br.open(url)
print(br.title())
print("selecting form")
br.select_form(name='Login')
br['UserID'] = username
br['PassPhrase'] = password
print("submitting form"
br.submit()
response = br.submit()
pageSource = response.read()

但它也报错

mechanize._response.httperror_seek_wrapper: HTTP Error 403: b'request disallowed by robots.txt'

安装 facebook 包

pip install facebook-sdk

然后 update/edit 一个 post 在你的页面上只是运行

import facebook

page_token = '...'
page_id = '...'
post_id = '...'
fb = facebook.GraphAPI(access_token = page_token, version="2.12")
fb.put_object(parent_object=page_id+'_'+post_id, connection_name='', message='new text')
