使用python Blogger API时Status参数不起作用

问题描述

我正在尝试将google-api-python-client 1.12.5与Python 3.8下的服务帐户auth一起使用。在我看来，当指定status参数时，Google会以404 HTTP代码进行响应。我不知道为什么。我也查看了文档，但无法将任何错误与此错误相关。

我粘贴了我的代码。错误发生在第三个调用中。

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：

解决方法

我可以重现此问题...添加status = DRAFT将返回404，但其他任何过滤器都可以正常工作...

尝试使用服务帐户和您的代码：404
已尝试使用API密钥，例如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”（通话后{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

但是非常奇怪的是，如果我在这里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"}使用“尝试此API”给出的access_token ，就可以了！

在请求中使用该令牌使我的博客帖子处于草稿状态...

只需在脚本中复制/粘贴原始Authorization标头：

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，而是来自令牌权限...但是，我通常也使用控制台来生成像您这样的访问。

总而言之，我认为这是错误或者是Google自愿提供的...我不知道“尝试使用此API”令牌有效的时间长短，但这是我找到文章草稿的唯一途径。 ..也许您可以尝试打开一个故障单，但是我不知道具体在哪里可以做到。
