在R的httr包中使用oauth2.0令牌 [英] Using oauth2.0 tokens with R's httr package

问题描述

软件包 httr 在R中提供了CURL包装器（请参见软件包文档）。

The package httr provides CURL wrappers in R (see package documentation).

我是HTTP和API的新手。我的麻烦是让oauth2.0身份验证起作用。我尝试了各种语法，并得到错误或状态401。

I'm brand new to HTTP and APIs. My trouble is getting oauth2.0 authentication to work. I have tried various syntax and get either errors or status 401.

使用oauth2.0令牌并生成 GET（ ）使用 httr 的请求？

What is the correct way to use an oauth2.0 token and make a GET() request using httr?

# Set UP
  
  url = "https://canvas.{institution}.edu/api/v1/courses"
  key = "{secret_key}"

# 1
  GET(url, sign_oauth2.0(key)) 
  # Error: Deprecated: supply token object to config directly

# 2
  GET(url, config(sign_oauth2.0 = key)) 
  # unknown option: sign_oauth2.0

# 3
  GET(url, config = list(sign_oauth2.0 = key)) 
  # Status 401

推荐答案

解决方案

在此特定用例中-与画布API -请求的标头中需要其他信息。

Solution

In this particular use case—working with the Canvas API—additional information is required in the header of the request.

使用< httr R包中的code> GET 函数，使用 add_header 参数提供参数，包括您的oauth2键。

Using the GET function from the httr R package, use the add_header parameter to supply the argument including your oauth2 key.

如果您不想将密钥硬编码到请求中，请使用选项1（推荐）。或者，使用选项2并将密钥作为字符串插入。但是在两种情况下，键都是 Bearer。

Use Option 1 if you don't want to hard code your key into the request (recommended). Or, use Option 2 and insert the key as a string. But in both cases, "Bearer " precedes the key.

# Set Up
url = "https://canvas.{institution}.edu/api/v1/courses"
key = "{secret_key}"

# OPTION 1
GET(url, add_headers(Authorization = paste("Bearer", key, sep = " ")))

# OPTION 2
courses.request = GET(url, add_headers(Authorization = "Bearer {secretkey}"))
