Question

我提到尝试在我之前的StackOverflow问题中使用google java示例代码，但在意识到样本被弃用之后放弃了尝试这样做。自从我在大约4年前涉足python之后，我决定看一下用于Python的Google Blogger API。

虽然大多数API调用都有意义，但我似乎无法正确运行此示例！

以下是我尝试运行的示例：

"""Simple command-line sample for Blogger.

Usage:
  $ python blogger.py

You can also get help on all the command-line flags the program understands
by running:

  $ python blogger.py --help

To get detailed log output run:

  $ python blogger.py --logging_level=DEBUG
"""
from __future__ import print_function

__author__ = 'jcgregorio@google.com (Joe Gregorio)'

import sys

from oauth2client import client
from googleapiclient import sample_tools


def main(argv):
  # Authenticate and construct service.
  service, flags = sample_tools.init(
      argv, 'blogger', 'v3', __doc__, __file__,
      scope='https://www.googleapis.com/auth/blogger')

  try:

      users = service.users()

      # Retrieve this user's profile information
      thisuser = users.get(userId='self').execute()
      print('This user\'s display name is: %s' % thisuser['displayName'])

      blogs = service.blogs()

      # Retrieve the list of Blogs this user has write privileges on
      thisusersblogs = blogs.listByUser(userId='self').execute()
      for blog in thisusersblogs['items']:
        print('The blog named \'%s\' is at: %s' % (blog['name'], blog['url']))

      posts = service.posts()

      # List the posts for each blog this user has
      for blog in thisusersblogs['items']:
        print('The posts for %s:' % blog['name'])
        request = posts.list(blogId=blog['id'])
        while request != None:
          posts_doc = request.execute()
          if 'items' in posts_doc and not (posts_doc['items'] is None):
            for post in posts_doc['items']:
              print('  %s (%s)' % (post['title'], post['url']))
          request = posts.list_next(request, posts_doc)

  except client.AccessTokenRefreshError:
    print ('The credentials have been revoked or expired, please re-run'
      'the application to re-authorize')

if __name__ == '__main__':
  main(sys.argv)

我已经在PyCharm和终端中运行了这个示例，并且代码编译并运行（这比我对Java样本的说法更多！）我似乎无法跟踪样本获取它的位置信息。

该示例需要一个client_secrets.json文件，我使用我的客户端ID和从Google API控制台获取的客户端机密密钥填充该文件，但是，我不知道该示例应如何获取当前数据博主用户，因为它似乎不是选择用户，输入电子邮件地址或类似内容的输入。该服务显然获得了当前用户，但实际上并没有这样做。

的client_secrets.json：

{
  "web": {
    "client_id": "[[INSERT CLIENT ID HERE]]",
    "client_secret": "[[INSERT CLIENT SECRET HERE]]",
    "redirect_uris": [],
    "auth_uri": "https://accounts.google.com/o/oauth2/auth",
    "token_uri": "https://accounts.google.com/o/oauth2/token"
  }
}

实际上，运行此代码后，我收到以下错误：

/usr/local/Cellar/python/2.7.11/Frameworks/Python.framework/Versions/2.7/bin/python2.7 /google-api-python-client-master/samples/blogger/blogger.py
This user's display name is: Unknown
Traceback (most recent call last):
  File "/google-api-python-client-master/samples/blogger/blogger.py", line 83, in <module>
    main(sys.argv)
  File "/google-api-python-client-master/samples/blogger/blogger.py", line 62, in main
    for blog in thisusersblogs['items']:
KeyError: 'items'

Process finished with exit code 1

如果有人能帮我理解我对这个样本的工作方式的理解，我一定会很感激。我的python肯定是生锈的，但我希望玩这个示例代码可以帮助我再次使用它。

示例代码是自解释的：

#libraries used to connect with googles api
from oauth2client import client
from googleapiclient import sample_tools


def main(argv):
  # Authenticate and construct service.
  service, flags = sample_tools.init(
      argv, 'blogger', 'v3', __doc__, __file__,
      scope='https://www.googleapis.com/auth/blogger')

以上使用Oath2 Flow，您被重定向并需要进行身份验证（至少在您第一次运行时）

 try:

      users = service.users()    #googleapiclient.discovery.Resource object

      # Retrieve this user's profile information
      thisuser = users.get(userId='self').execute()
      print('This user\'s display name is: %s' % thisuser['displayName'])

      blogs = service.blogs()   #googleapiclient.discovery.Resource object

 # Retrieve the list of Blogs this user has write privileges on
      thisusersblogs = blogs.listByUser(userId='self').execute()  #retrieves all blogs from the user (you = self) 
      for blog in thisusersblogs['items']:    #for loop that iterates over a JSON (dictionary) to get key value 'items'
        print('The blog named \'%s\' is at: %s' % (blog['name'], blog['url']))

      posts = service.posts()    #googleapiclient.discovery.Resource object for posts

  # List the posts for each blog this user has
      for blog in thisusersblogs['items']:
        print('The posts for %s:' % blog['name'])  
        request = posts.list(blogId=blog['id'])     #uses #googleapiclient.discovery.Resource object for posts to get blog by id
        while request != None:
          posts_doc = request.execute()
          if 'items' in posts_doc and not (posts_doc['items'] is None):
            for post in posts_doc['items']:
              print('  %s (%s)' % (post['title'], post['url']))
          request = posts.list_next(request, posts_doc)

  except client.AccessTokenRefreshError:
    print ('The credentials have been revoked or expired, please re-run'
      'the application to re-authorize')

if __name__ == '__main__':
  main(sys.argv)

运行此命令将返回您的所有帖子，如下所示：

This user's display name is: "something"
The blog named 'myTest' is at: http://BLOGNAME.blogspot.com/
The posts for myTest:
  POST NAME (http://BLOGNAME.blogspot.com/2016/06/postname.html)

也许您想开始使用基本请求而不是代码示例来熟悉API？

https://developers.google.com/blogger/docs/3.0/using#RetrievingABlog

从基础知识开始，例如：

检索博客

您可以通过发送HTTP来检索特定博客的信息   GET请求博客的URI。博客的URI具有以下内容   格式：

https://www.googleapis.com/blogger/v3/blogs/blogId

根据您使用的pyton版本，您可以导入不同的库来执行您的请求，例如。来自http://docs.python-requests.org/en/master/user/quickstart/#make-a-request

import requests

r = requests.get('https://www.googleapis.com/blogger/v3/blogs/blogId')
print r.text

这应该重新调整JSON：

{
  "kind": "blogger#blog",
  "id": "2399953",
  "name": "Blogger Buzz",
  "description": "The Official Buzz from Blogger at Google",
  "published": "2007-04-23T22:17:29.261Z",
  "updated": "2011-08-02T06:01:15.941Z",
  "url": "http://buzz.blogger.com/",
  "selfLink": "https://www.googleapis.com/blogger/v3/blogs/2399953",
  "posts": {
    "totalItems": 494,
    "selfLink": "https://www.googleapis.com/blogger/v3/blogs/2399953/posts"
  },
  "pages": {
    "totalItems": 2,
    "selfLink": "https://www.googleapis.com/blogger/v3/blogs/2399953/pages"
  },
  "locale": {
    "language": "en",
    "country": "",
    "variant": ""
  }
}

Answer 2

添加了一个使用Python客户端库的Google驱动器的基本工作示例。

Python客户端库推荐

我将添加另一个示例，将google drive与python客户端库一起使用。

首先，我强烈建议使用PyDrive库，该库使OAuth流程更加容易（使用pip：pip install PyDrive安装）。

here中的更多详细信息。

如何运行与Google驱动器进行交互的基本python代码？

1）转到API控制台并创建自己的项目。

2）搜索“ Google Drive API”，选择条目，然后单击“启用”。

3）从左侧菜单中选择“凭据”，点击“创建凭据”，然后选择“ OAuth客户端ID”。

4）现在，需要设置产品名称和同意屏幕->单击“配置同意屏幕”，然后按照说明进行操作。完成后：

a。选择“应用程序类型”作为Web应用程序。

b。输入适当的名称。

c。为http://localhost:8080输入Authorized JavaScript origins。

d。为http://localhost:8080/输入Authorized redirect URIs。

e。点击“创建”。

5）单击客户端ID右侧的“下载JSON”以下载client_secret_<long ID>.json。
下载的文件包含您应用程序的所有身份验证信息。
重命名文件为“ client_secret s .json”并将其放置在您的工作目录中。

基本代码示例

添加您的代码并运行它-例如，返回根目录中所有文件的基本代码：

from pydrive.auth import GoogleAuth
from pydrive.drive import GoogleDrive

gauth = GoogleAuth()
gauth.LocalWebserverAuth()

drive = GoogleDrive(gauth)


# Auto-iterate through all files that matches this query
file_list = drive.ListFile({'q': "'root' in parents and trashed=false"}).GetList()
for file1 in file_list:
  print('title: %s, id: %s' % (file1['title'], file1['id']))

如果您在身份验证过程中收到403授权错误

您必须至少将Gmail帐户添加为测试用户才能继续进行身份验证流程：
