python - 使用python blogger api时状态参数不起作用

Question

我正在尝试在 Python 3.8 下使用带有服务帐户身份验证的 google-api-python-client 1.12.5。在我看来，指定状态参数时，Google 会以 404 HTTP 代码响应。我不明白为什么。我也查看了文档，但我无法将任何与此错误相关联。
我已经粘贴了我的代码。错误发生在第三次调用中。
这是代码:

from google.oauth2 import service_account
from googleapiclient.discovery import build

SCOPES = ['https://www.googleapis.com/auth/blogger']
SERVICE_ACCOUNT_FILE = 'new_service_account.json'
BLOG_ID = '<your_blog_id>'

credentials = service_account.Credentials.from_service_account_file(
        SERVICE_ACCOUNT_FILE, scopes=SCOPES)

service = build('blogger', 'v3', credentials=credentials)
p = service.posts()

# FIRST
promise = p.list(blogId=BLOG_ID)
result = promise.execute()

# SECOND
promise = p.list(blogId=BLOG_ID, orderBy='UPDATED')
result = promise.execute()


#THIRD
promise = p.list(blogId=BLOG_ID, orderBy='UPDATED', status='DRAFT')
result = promise.execute()  # <===== ERROR HAPPENS HERE!!!!

service.close()

这是回溯:

我可以重现这个问题...添加 status=DRAFT 将返回 404 但任何其他过滤器都在工作...

尝试使用服务帐户和您的代码:404

尝试使用这样的 API key result = requests.get('https://blogger.googleapis.com/v3/blogs/<blog_id>/posts?status=DRAFT&orderBy=UPDATED&alt=json&key=<api_key>') : 404

从服务帐户中提取“access_token”(调用后 credentials.token):result = requests.get('https://blogger.googleapis.com/v3/blogs/<blog_id>/posts?status=DRAFT&orderBy=UPDATED&alt=json&access_token=<extracted_service_account_token>') : 404

但很奇怪如果我 使用“尝试此 API”提供的 access_token 这里: https://developers.google.com/blogger/docs/3.0/reference/posts/list?apix_params={"blogId"%3A"blog_id"%2C"orderBy"%3A"UPDATED"%2C"status"%3A["DRAFT"]%2C"alt"%3A"json"}其作品 !
使用该 token 与请求给我我的博客文章处于草稿状态......

只需复制/粘贴原始 Authorization该脚本中的标题:

import requests

blog_id = '<blog_id>'
headers = {
    'Authorization' : 'Bearer <replace_here>'
}

# Using only Authorization header
result = requests.get(
    'https://blogger.googleapis.com/v3/blogs/%s/posts?status=DRAFT&orderBy=UPDATED&alt=json' % (blog_id),
    headers=headers
)
print(result)
# This should print DRAFT if you have at least one draft post
print(result.json()['items'][0]['status'])

# Using "access_token" param constructed with Authorization header splited to have only token
result = requests.get('https://blogger.googleapis.com/v3/blogs/%s/posts?status=DRAFT&orderBy=UPDATED&alt=json&access_token=%s' % (blog_id, headers['Authorization'][len('Bearer '):]))
print(result)
# This should print DRAFT if you have at least one draft post
print(result.json()['items'][0]['status'])

我目前的结果:

该错误似乎不是来自库，而是来自 token 权限......但是我通常也使用控制台来生成像您一样的访问。
总而言之，我认为这要么是一个错误，要么是 Google 自愿提供的……我不知道“试用此 API” token 的有效期有多长，但它目前是我找到的获取文章草稿的唯一方法……也许您可以尝试打开一个错误票，但我不知 Prop 体在哪里可以做到这一点。
