Zuora Rest APIをRで使用する

Question

Zuoraからデータを取り込もうとしていますが、rjsonがエラーを投げています。

library(httr) 
library(rjson) 

query <- "https://api.zuora.com/rest/v1" 
getdata <- GET(url=query, add_headers(apiAccessKeyId="Username", apiSecretAccessKey = "Password", Content-Type = "application/json")) 
q <- fromJSON(content(getdata,type="text")) 

エラー：任意の助けを大幅に高く評価され

No encoding supplied: defaulting to UTF-8. 
Error in fromJSON(content(getdata, type = "text")) : 
    unexpected character '<' 

。

Answer 1

auth <- add_headers(apiAccessKeyId = "username", apiSecretAccessKey = "password") 
body = paste('{ 
    "Format": "csv", 
      "Name": "test", 
      "Query": "select * from invoice", 
      "Status": "Processing", 
      "Zip": false 
      }') 

getdata <- POST("https://rest.zuora.com/v1/object/export", auth, body = body) 
r <- fromJSON(content(getdata, type = "text"))
