奇怪的问题，为什么用restful api删除就会出现404的问题呢

代码：

import requests
import json
import base64

url = "https://www.xacisco.net/blog/wp-json/wp/v2/doc"
user = "xxxx"
password = "xxx"
credentials = user + ':' + password
token = base64.b64encode(credentials.encode())
header = {'Authorization': 'Basic ' + token.decode('utf-8')}
postID='39823'
responce = requests.delete(url + postID , headers=header)
print(responce)

遇到的都是404的错误
