使用包 httr、twitteR 和 streamR 检索缓存的 oauth 令牌 [英] Retrieving cached oauth token with packages httr, twitteR, and streamR

问题描述

我发现通过 Twitter API 验证自己的唯一方法如下:

图书馆(twitteR)setup_twitter_oauth(consumer_key = "a",消费者秘密 = "b",access_token = "c",access_secret = "d")

运行这个后，我可以使用twitteR中的所有功能就好了.但是，我也想使用 streamR 包，它需要令牌作为 OAuth 对象:

filterStream("tweets.json", track = c("Obama", "Biden"), timeout = 20, oauth=my_oauth)

据我所知，上面的 setup_twitter_oauth 函数是一些 httr 函数的包装器，用于获取我的授权令牌.此令牌作为名为.httr-oauth"的文件缓存在我的工作目录中.我的问题是:如何将此文件加载到 R 中，以便获得可与 streamR 一起使用的 OAuth 对象?

解决方案

使用 readRDS()

<前>readRDS('.httr-oauth')$xxxx0x000xxxx00000x0xx0x000000xx请求:https://api.twitter.com/oauth/request_token授权:https://api.twitter.com/oauth/authenticate访问:https://api.twitter.com/oauth/access_token推特密钥:xxxxxxxxx0xxxxxxxxxxxxxxx秘密:oauth_token、oauth_token_secret、user_id、screen_name

通过$long-alphanumeric-hash 访问列表中的环境，并在该访问中$credentials 和$oauth_token/$oauth_token_secret

The only way I've found to get myself authenticated with the twitter API is the following:

library(twitteR)

setup_twitter_oauth(consumer_key = "a", 
                consumer_secret = "b", 
                access_token = "c", 
                access_secret = "d")

After running this, I can use all functions in twitteR just fine. However, I would also like to use the streamR package, which needs the token as an OAuth object:

filterStream("tweets.json", track = c("Obama", "Biden"), timeout = 20, oauth=my_oauth)

From what I gather, the setup_twitter_oauth function above is a wrapper around some httr functions to get my authorization token. This token is cached in my working directory as a file called ".httr-oauth". My question is: how do I load this file into R, such that I get an OAuth object that I can use with streamR?

解决方案

Use readRDS()

readRDS('.httr-oauth')
$xxxx0x000xxxx00000x0xx0x000000xx


 request:   https://api.twitter.com/oauth/request_token
 authorize: https://api.twitter.com/oauth/authenticate
 access:    https://api.twitter.com/oauth/access_token
 twitter
  key:    xxxxxxxxxx0xxxxxxxxxxxxxx
  secret: 
 oauth_token, oauth_token_secret, user_id, screen_name

Access the environment in the list through $long-alphanumeric-hash and within that access $credentials and $oauth_token/$oauth_token_secret
