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

Question

After a lot of Google I landed up here: How can I set a post Thumbnail using an external image link from an instead of attachment id? .

Here is all that I can find, however I can't change it to set the thumbnail from an external image link.

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))

Note : I don't want to save image on my servers and use an external image only

You could try downloading the image, uploading it to your Wordpress site, and using the ID for the thumbnail parameter as you are above:

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

# ...
