【问题描述】:
我正在尝试从“idealista”(link) 的 API 发出请求。
它需要身份验证,所以我做的是下一个:
if(!require("jsonlite")){install.packages("jsonlite")}
if(!require("httr")){install.packages("httr")}
consumer_key <- "my_key"
consumer_secret <- "my_secret"
#Use basic auth
secret <- jsonlite::base64_enc(paste(consumer_key, consumer_secret, sep = ":"))
req <- httr::POST("https://api.idealista.com/oauth/token",
httr::add_headers(
"Authorization" = paste("Basic", gsub("\n", "", secret)),
"Content-Type" = "application/x-www-form-urlencoded;charset=UTF-8"
),
body = "grant_type=client_credentials"
)
#Extract the access token
token <- paste("Bearer", jsonlite::base64_enc(httr::content(req)$access_token))
所以,首先:我不知道令牌是否必须是 base64 编码(我认为是的)。我做了以下请求:
url<-"https://api.idealista.com/3.5/es/search?locale=es&maxItems=20&numPage=1&operation=sale&order=publicationDate&propertyType=garages&apikey=my_key&t=1&language=es&bankOffer=true" #an example of url (needs apikey)
req <- httr::GET(url, httr::add_headers("Authorization" = token))
响应是:
Response [https://api.idealista.com/3.5/es/search?locale=es&maxItems=20&numPage=1&operation=sale&order=publicationDate&propertyType=garages&apikey=80gzxznozajnl3tf30ite86k1p24e4yb&t=1&language=es&bankOffer=true]

这没有意义。你能告诉我我做错了什么吗? 我收到的状态码是“400”,我不知道我必须做什么。
提前致谢。

这似乎完全特定于 Idealista.com API。您可能应该联系他们寻求支持。或者至少提供其 API 文档相关部分的链接。您真的要添加两个 Authorization 标头吗?
