Phantomjs returns 404 in R when attempting webscraping
0
I am trying to collect some data from the OTC Markets (within the confines of their robots.txt) and I cannot connect to the webpage.
- The first step I tried was just to scrape the HTML right off the page, but the page requires javascript to load.
- So I downloaded phantomjs and connected that way. However, this leads to a 404 error page
- I then changed the user-agent to something resembling a user to see if it would let me connect and still, no luck! What is going on here
Here is a reproducible version of my code, any help would be appreciated. Phantomjs can be downloaded here: http://phantomjs.org/
library(rvest)
library(xml2)
library(V8)
# example website, I have no correlation to this stock
url <- 'https://www.otcmarkets.com/stock/YTROF/profile'
# create javascript file that phantomjs can process
writeLines(sprintf("var page = require('webpage').create();
page.settings.userAgent = 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/37.0.2062.120 Safari/537.36';
page.open('%s', function ()
console.log(page.content); //page source
phantom.exit();
);", url), con="scrape.js")
html <- system("phantomjs.exe_PATH scrape.js", intern = TRUE)
page_html <- read_html(html)
r web-scraping phantomjs

totally up to you. This is a regularly occurring thing on SO (esp in the R tag). For some reason folks haven't picked up on async XHR requests yet.
