R：无法读取 API 调用 - open.connection 中的错误（con，“rb”）

Question

我可以在 webbrowser 中看到 API 调用的内容，但是使用 jsonlite 包出现此错误：read_json。

Error in open.connection(con, "rb") : connection cannot be opened
Añso: Warning message:
In open.connection(con, "rb") :
  cannot open URL 'https://www.plazavea.com.pe/api/catalog_system/pub/products/search?fq=C:/678/687/&_from=21&_to=41&O=OrderByScoreDESC&': HTTP status was '206 Partial Content'

代码：：

library(rvest)
library(tidyverse)
library(jsonlite)



api_request <- "https://www.plazavea.com.pe/api/catalog_system/pub/products/search?fq=C:/678/687/&_from=21&_to=41&O=OrderByScoreDESC&"

product_data <- jsonlite::read_json(api_request)

Answer 1

使用 httr 然后提取 as = 'text' 并传递给 parse_json()，或者在响应对象上的 content() 调用中简单地指定 as = 'parsed'。

library(httr)

api_request <- "https://www.plazavea.com.pe/api/catalog_system/pub/products/search?fq=C:/678/687/&_from=21&_to=41&O=OrderByScoreDESC&"

product_data <- content(httr::GET(api_request), as = 'parsed')
