如何使用 API 和 python 将图像添加到现有的 facebook post？

Question

我正在使用 facebook graph API 来 update/edit 我页面上特定 post 的文本

import facebook

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

现在我正在尝试向此 post 添加本地图像（存储在 python 脚本的同一文件夹中），但我不知道如何正确地执行此操作，我尝试过

fb.put_object(parent_object=page_id+'_'+post_id, connection_name='', message='new text', source = open('out.png', 'rb'))

和

fb.put_object(parent_object=page_id+'_'+post_id, connection_name='', message='new text', object_attachment = open('out.png', 'rb'))

但其中 none 有效。提示？

p.s。这些是我的应用程序的许可

pages_show_list
pages_read_engagement
pages_read_user_content
pages_manage_posts
pages_manage_engagement

编辑：我尝试使用函数 put_photo 但它创建了一个新的 post 添加图像，而我需要将图像添加到已经存在的 post

我在 python 中制作了一个完整的 selenium 脚本，它可以处理相同的任务：

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.chrome.options import Options
import time
import pyautogui as pag
option = Options()

option.add_argument("--disable-infobars")
option.add_argument("start-maximized")
option.add_argument("--disable-extensions")

# Pass the argument 1 to allow and 2 to block
option.add_experimental_option("prefs", { 
    "profile.default_content_setting_values.notifications": 1 
})
