在我之前关于StackOverflow的一个问题中,我提到尝试让GoogleJava示例代码工作,但在意识到这些示例是多么不受欢迎之后,我放弃了尝试。由于大约4年前我涉猎过python,我决定看看Google Blogger API for python

虽然大多数API调用都有意义,但我似乎无法使此示例正确运行

以下是我尝试运行的示例:

"""Simple command-line sample for Blogger.

Command-line application that retrieves the users blogs and posts.

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

我已经在PyCharm和终端中运行了这个示例,当代码编译和运行时(对于Java示例,这比我所能说的还要多!),我似乎无法理解示例从何处获得信息

该示例需要一个client_secrets.json文件,我用从Google API控制台获得的客户端id和客户端密钥填充了该文件,但是,我不知道该示例应该如何获取当前blogger用户的数据,因为似乎没有用于选择用户、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,但实际上似乎没有这样做

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"
  }
}
事实上,在运行此代码时,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

如果有人能帮助我理解我在理解这个示例如何工作时遗漏了什么,我将不胜感激。我的python肯定已经生锈了,但我希望使用这个示例代码可以帮助我再次使用它。

示例代码是不言自明的:

#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')
上面使用的是Oath2流,您将被重定向并需要进行身份验证(至少在您第一次运行此流时)

运行此命令将返回所有帖子,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)
也许您想从基本请求开始,而不是从代码示例开始,以熟悉API

从基础开始,例如:

检索博客

您可以通过发送HTTP来检索特定博客的信息 获取对博客URI的请求。博客的URI包含以下内容 格式:

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。 从

这应该是一个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",

您可能想查看添加一个使用Python客户端库使用Google drive的基本工作示例

Python客户端库建议

我将添加另一个将GoogleDrive与python客户端库结合使用的示例

首先,我强烈建议使用使OAuth过程更容易的库(使用pip安装:
pip安装PyDrive

更多详情请参阅


如何运行与Google drive交互的基本python代码?

1)转到API控制台,制作您自己的项目

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”,单击“创建凭据”,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。输入<代码>http://localhost:8080用于
授权的JavaScript源代码

d。输入<代码>http://localhost:8080/用于
授权重定向URI

e。单击“创建”

5)点击客户端ID右侧的“下载JSON”下载
Client\u secret\u.JSON

下载的文件包含应用程序的所有身份验证信息
将文件重命名为“client_secrets.json”,并将其放在工作目录中


基本代码示例

添加代码并运行它-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']))

如果在身份验证过程中收到403授权错误

您必须至少以测试用户身份添加您的gmail帐户,才能继续验证流程:

我更新了我的问题,添加了更多关于客户机密的信息,这些信息似乎没有提及用户ID。我将尝试在这部分代码中输入userId,谢谢!示例代码来自这里:。由于某些原因,他们的文档对我来说并不直接,所以希望你的建议能奏效!不幸的是,更改“self”引用实际上导致http请求中断。顺便说一下,感谢您对Http请求的深入了解!我刚刚在学校完成了一个处理http请求的项目,所以这也很有帮助。也许我只是对这个示例期望过高,因为我从文档中收集到它已经为我创建了http请求。我刚刚添加了blogger API参考指南,这是您真正想要使用的。我开始怀疑blogger API是否真的是我想要实现的目标。我的项目包括获取一个博客URL列表,并获取与这些博客相关的所有帖子数据。也许有可能,但我不确定。我仍然很想让示例代码正常工作,就像
