请教关于R调用Google Analytics的API

[dayushan]

吴老师，我最近需要使用GA，但是ＧＡ每次最多能导５０００条数据，所以我想通过ＡＰＩ来提高效率。RGoogleAnalytics包可以实现Ｒ调用ＧＡ的ＡＰＩ，但是我想问下Ａｕｔｈ（）函数的参数client.id和client.secret分别是客户端ID和客户端秘钥吗？

我没有用过 RGoogleAnalytics 包，不过可以查一下它的接口文档：https://cran.r-project.org/web/packages/RGoogleAnalytics/RGoogleAnalytics.pdf ，里面关于 Auth() 函数的说明如下：

Description

This function expects a Client ID and Client Secret. In order to obtain these, you will have to
register an application with the Google Analytics API. This can be done as follows

• Go to https://console.developers.google.com
• Create a New Project and enable the Google Analytics API
• On the Credentials screen, create a new Client ID for Application Type "Installed Application".
• Copy the Client ID and Client Secret to your R Script as shown in the Examples section below

Usage

Auth(client.id, client.secret)

Arguments

client.id Equivalent to a user name
client.secret Equivalent to a password

Details

When evaluated for the first time this function asks for User Consent for the Google Analytics
Account and creates a OAuth Token Object. The token object can be saved locally to a file on the
user’s system. In subsequent runs, User Consent is not required unless you are querying a Google
Analytics profile associated with a different email account. This function uses oauth2.0_token
under the hood to create the OAuth Tokens. The Access Token has a 60 minute lifetime after which
it expires and a new token has to be obtained. This can be done using the ValidateToken method

Value

google.token A Token object containing all the data required for OAuth access. See Token2.0 for
additional information on the Token object

Examples

## Not run:
# Generate the oauth_token object
oauth_token <- Auth(client.id = "150487456763-XXXXXXXXXXXXXXX.apps.googleusercontent.com",
client.secret = "TUXXXXXXXXXXXX_TknUI")
# Save the token object for future sessions
save(oauth_token, file="oauth_token")
# Load the token object

应该照着 Description 里面的几个步骤就能得到这两个参数。如果还不清楚的话，也可以去查阅 GA 的 API 文档： https://developers.google.com/analytics/?hl=zh-cn

对 我都查阅了相关文档，但是R中代码报错：

一直没查出原因，所以跟老师求助来了

在 RGoogleAnalytics 包的 GitHub repo 上有几个人都提了同样的问题，但是作者一直没有回应，最后有人说解决的办法是重装 R 。 Tatvic/RGoogleAnalytics#33

另外，你是否用了 proxy 来访问 Google ？如果是这样的话，httr 需要设置 proxy 参数。

library(httr)
set_config(use_proxy(url = "*****", port = xxxx))

[dayushan]

吴老师 根据您的建议问题已得到解决，我用了 proxy 来访问 Google，对httr 设置 proxy 参数。

library(httr)
set_config(use_proxy(url = "*****", port = xxxx))

并且换了版本，使用R 3.3.2 -64bit
感谢！

不客气，R 的版本兼容性问题确实很麻烦，需要耐心调试。
