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

Question

我尝试在 Python 3.8 下使用 google-api-python-client 1.12.5 和服务帐户身份验证。在我看来，当指定状态参数时，Google 会使用 404 HTTP 代码进行响应。我不明白为什么。我也查看了文档，但我无法将任何内容与此错误联系起来。

我已经粘贴了我的代码。第三次调用时发生错误。

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:

我可以重现此问题...添加 status=DRAFT 将返回 404，但任何其他过滤器正在工作...

1. 尝试使用服务帐户和代码:404

2. 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

3. 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

但非常奇怪的是，如果我在这里使用“尝试这个API”给出的access_token: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"}这是有效的!

使用该 token 请求给我提供处于草稿状态的博客文章...

只需复制/粘贴原始 Authorization该脚本内的 header :

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...但是我也像您一样正常使用控制台来生成访问。

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“尝试此 API” token 的有效期是多长时间，但这是目前我发现获取文章草稿的唯一方法。 ..也许您可以尝试打开错误单，但我不知 Prop 体在哪里可以做到这一点。
