Using oauth2.0 tokens with R's httr package

由 …衆ロ難τιáo~ 提交于 2019-12-12 08:48:32
问题 Problem The package httr provides CURL wrappers in R (see package documentation). I'm brand new to HTTP and APIs. My trouble is getting oauth2.0 authentication to work. I have tried various syntax specifications and get either errors or status 401. What is the correct way to use an oauth2.0 token and make a GET() request using httr ? Code Attempts # Set UP url = "https://canvas.{institution}.edu/api/v1/courses" key = "{secret_key}" # 1 GET(url, sign_oauth2.0(key)) # Error: Deprecated: supply

问题 My requirement/objective: I'm retrieving Facebook posts for the past 3 months from a public page, and I would like to select only those posts which have been modified in the recent past (in the last 2 days).

I tried the following : url.data <- GET(url, config(token=token), config(add_headers("If-Modified-Since" = "2016-09-08 11:45"))) url.data <- GET(url, config(token=token, add_headers("If-Modified-Since" = "2016

R Download .csv file tied to input boxes and a “click” button

问题 I am attempting to download a .csv file from https://www.fantasysharks.com/apps/bert/forecasts/projections.php? that is tied directly the input settings (is not a static download link) and load it into R.

How to POST multipart binary & non-binary with httr (for Salesforce API)

由 核能气质少年 提交于 2019-12-12 03:33:59
问题 I'm having some trouble using httr to POST a file to Salesforce's REST API. I thought this SO question might take care of it, but didn't seem to. I have a hunch that this is because Saleforce wants a non-binary part and upload_file creates an object of class form_file that's handled as a binary, but maybe someone has an alternate explanation/solution... Salesforce asks for the following curl request to insert a new document: curl https://yourInstance.salesforce.com/services/data/v23.0
