Scraping Craigslist Listings with Go

Oct 1, 2023 · 4 min read

This article explains how to scrape Craigslist apartment listings using Go and the goquery package. We'll walk through each part of the code.

First install goquery:

go get github.com/PuerkitoBio/goquery

And import it:

import (
  "fmt"
  "net/http"

  "github.com/PuerkitoBio/goquery"
)

Goquery allows querying HTML/XML docs similar to jQuery.

We'll scrape Craigslist SF apartments:

url := "<https://sfbay.craigslist.org/search/apa>"

Make the HTTP request to get the HTML:

res, err := http.Get(url)
page, err := goquery.NewDocumentFromReader(res.Body)

If you check the source code of Craigslist listings you can see that the listings area code looks something like this…

You can see the code block that generates the listing…

<li class="cl-static-search-result" title="Situated in Sunnyvale!, Recycling Center, 1/BD">
            <a href="https://sfbay.craigslist.org/sby/apa/d/santa-clara-situated-in-sunnyvale/7666802370.html">
                <div class="title">Situated in Sunnyvale!, Recycling Center, 1/BD</div>

                <div class="details">
                    <div class="price">$2,150</div>
                    <div class="location">
                        sunnyvale
                    </div>
                </div>
            </a>
        </li>

its encapsulated in the cl-static-search-result class. We also need to get the title class div and the price and location class divs to get all the data

Find all apartment listings:

page.Find("li.cl-static-search-result").Each(func(i int, s *goquery.Selection) {

})

Inside, extract the title, price, location and link:

title := s.Find(".title").Text()
price := s.Find(".price").Text()
location := s.Find(".location").Text()
link, _ := s.Find("a").Attr("href")

fmt.Printf("%s %s %s %s\\n", title, price, location, link)

The full Go code is:

import (
  "fmt"
  "net/http"

  "github.com/PuerkitoBio/goquery"
)

url := "<https://sfbay.craigslist.org/search/apa>"

res, err := http.Get(url)
page, err := goquery.NewDocumentFromReader(res.Body)

page.Find("li.cl-static-search-result").Each(func(i int, s *goquery.Selection) {

  title := s.Find(".title").Text()
  price := s.Find(".price").Text()
  location := s.Find(".location").Text()
  link, _ := s.Find("a").Attr("href")

  fmt.Printf("%s %s %s %s\\n", title, price, location, link)
})

This walks through scraping Craigslist listings in Go.

This is great as a learning exercise but it is easy to see that even the proxy server itself is prone to get blocked as it uses a single IP. In this scenario where you may want a proxy that handles thousands of fetches every day using a professional rotating proxy service to rotate IPs is almost a must.

Otherwise, you tend to get IP blocked a lot by automatic location, usage, and bot detection algorithms.

Our rotating proxy server Proxies API provides a simple API that can solve all IP Blocking problems instantly.

  • With millions of high speed rotating proxies located all over the world,
  • With our automatic IP rotation
  • With our automatic User-Agent-String rotation (which simulates requests from different, valid web browsers and web browser versions)
  • With our automatic CAPTCHA solving technology,
  • Hundreds of our customers have successfully solved the headache of IP blocks with a simple API.

    The whole thing can be accessed by a simple API like below in any programming language.

    In fact, you don't even have to take the pain of loading Puppeteer as we render Javascript behind the scenes and you can just get the data and parse it any language like Node, Puppeteer or PHP or using any framework like Scrapy or Nutch. In all these cases you can just call the URL with render support like so:

    curl "<http://api.proxiesapi.com/?key=API_KEY&render=true&url=https://example.com>"
    
    

    We have a running offer of 1000 API calls completely free. Register and get your free API Key.
