使用 Python-xmlrpc 从外部图像链接设置 Wordpress 帖子缩略图

Question

经过大量的谷歌搜索，我来到了这里：如何使用来自附件ID的外部图像链接来设置帖子缩略图？

这是我能找到的所有内容，但是我无法更改它以从外部图像链接设置缩略图。

from wordpress_xmlrpc import Client, WordPressPost
from wordpress_xmlrpc.methods.posts import NewPost
#authenticate
wp_url = "https://blog.com/xmlrpc.php"
wp_username = "My_User_ID_on_WP"
wp_password = "My_PWD_on_WP"

wp = Client(wp_url, wp_username, wp_password)
#post and activate new post
post = WordPressPost()
post.title = '3 Post'
post.content = '<h1>heading 1</h1>Tayloe was here<br><small>here too!</small><p>New para.'
post.post_status = 'draft'
post.thumbnail = 50  # The ID of the image determined in Step 1
post.slug = "123abc"
post.terms_names = {
'post_tag': ['MyTag'],
'category': ['Category']
}
wp.call(NewPost(post))

注意：我不想在服务器上保存图像，而只能使用外部图像

您可以尝试下载图像，将其上传到Wordpress网站，并使用缩略图参数的ID进行，如上所示：

import base64
import requests
# ...
# raw string url
url = r'https://png.pngtree.com/element_our/20190530/ourmid/pngtree-cartoon-google-icon-download-image_1257171.jpg'
# retrieve and store base64 encoded image and mime-type
r = requests.get(url)
mime_type = r.headers['Content-Type']
img_base64 = base64.b64encode(r.content)
upload_image_dict = {
'name': 'some_file_name.ext',
'type': mime_type,
'bits': img_base64,
'overwrite': True
}
resp = wordpress_xmlrpc.methods.media.UploadFile(upload_image_dict)
image_id = resp['id']
# ... [ your code here]
post.thumbnail = image_id
# ...
