I am trying to scrape a website using a package in R.
When I run the following:
library(idealisto) #https://github.com/hmeleiro/idealisto
get_city("https://www.idealista.com/alquiler-viviendas/madrid-madrid/", "sale")
I get:
Error in read_html.response(.) : Forbidden (HTTP 403).
Looking into more details of the function get_city()
I find that the problem is with the following part of the code:
desktop_agents <- c("Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/54.0.2840.99 Safari/537.36",

url = "https://www.idealista.com/en/venta-viviendas/madrid-provincia/"
x <- GET(url, add_headers(`user-agent` = desktop_agents[sample(1:10, 1)]))
Which returns the following output:
Response [https://www.idealista.com/en/venta-viviendas/madrid-provincia/]
Date: 2022-04-04 18:52 Status: 403 Content-Type: application/json;charset=utf-8 Size: 360 B
However, I should be getting a Status: 200
. I try to pass some headers
manually but I still get the same Status
error:
headers = c(
'accept' = 'text/html,application/xhtml xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9',

)
url = "https://www.idealista.com/en/venta-viviendas/madrid-provincia/"
x <- GET(url, add_headers(headers))
Any idea how I can get around this Status
error?
CodePudding user response:
Your syntax for add_headers
is wrong. You can't pass a named vector - you have to pass the arguments directly to the function:
library(httr)
headers <- add_headers(
'accept' = 'text/html,application/xhtml xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9',
'accept-encoding' = 'gzip, deflate, br',
'accept-language' = 'es-ES,es;q=0.9,en;q=0.8',
'cache-control' = 'max-age=0',
'referer' = 'https://www.idealista.com/en/',
'sec-fetch-mode' = 'navigate',
'sec-fetch-site' = 'same-origin',
'sec-fetch-user' = '?1',
'upgrade-insecure-requests' = '1',
