Scrape Naver News Results with Python

#python #programming #tutorial #webscraping

This blog post you will see how to scrape title, link, snippet, news press name, date news published from Naver News Results using Python.

If you're already familiar with how I structure blog posts, then you can jump to what will be scraped section since the Intro, Prerequisites, and Import sections are, for the most part, boilerplate part.

This blog is suited for users with little web scraping experience.

Naver is the most widely used platform in South Korea and it is used there more than Google, based Link Assistant and Croud blog posts.

Intro

This blog post is the first of Naver web scraping series. Here you'll see how to scrape Naver News Results using Python with beautifulsoup, requests, lxml libraries.

Note: This blog post shows how to extract data that is being shown in the what will be scraped section, and don't cover different layout handling (unless said otherwise).

Prerequisites

pip install requests
pip install lxml 
pip install beautifulsoup4
Enter fullscreen mode Exit fullscreen mode

Make sure to have a basic knowledge of Python, have a basic idea of the libraries mentioned above, and have a basic understanding of CSS selectors because you'll see mostly usage of select()/select_one() beautifulsoup methods that accept CSS selectors.

Usually, I'm using SelectorGadget extension to grab CSS selectors by clicking on the desired element in the browser. CSS selectors reference, or train on a few examples via CSS Diner.

However, if SelectorGadget can't get the desired element, I use Elements tab via Dev Tools (F12 on a keyboard) to locate and grab CSS selector(s) or other HTML elements.

To test if the selector extracts correct data you can place those CSS selector(s) in SelectorGadget window, or via Dev Tools Console tab using $$(".SELECTOR") which is equivalent to document.querySelectorAll(".SELECTOR") to see if the correct elements being selected.

Imports

import requests, lxml
from bs4 import BeautifulSoup
Enter fullscreen mode Exit fullscreen mode

What will be scraped

All News Results from the first page.

what will be scraped from Naver News results

Process

If you don't need an explanation, jump to the code section.

There're not a lot of steps that needs to be done, we need to:

  1. Make a request and save HTML locally.
  2. Find correct CSS selectors or HTML elements from where to extract data.
  3. Extract data.

Make a request and save HTML locally

Why save locally?

The main point of this is to make sure that IP won't be banned or blocked for some time, which will delay the script development process.

When requests are being sent constantly (regular user won't do that) from the same IP, this could be detected (tagged or whatever, as unusual behavior) and blocked or banned to secure the website.

Try to save HTML locally first, test everything you need there, and then start making actual requests.

import requests

headers = {
    "User-Agent":
    "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.102 Safari/537.36 Edge/18.19582"
}

params = {
    "query": "minecraft",
    "where": "news",
}

html = requests.get("https://search.naver.com/search.naver", params=params, headers=headers).text

with open(f"{params['query']}_naver_news.html", mode="w") as file:
    file.write(html)
Enter fullscreen mode Exit fullscreen mode

What we've done here?

Import a requests library 

import requests
Enter fullscreen mode Exit fullscreen mode

Add user-agent 

headers = {
    "User-Agent":
    "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.102 Safari/537.36 Edge/18.19582"
}
Enter fullscreen mode Exit fullscreen mode

Add search query parameters 

params = {
    "query": "minecraft",  # search query
    "where": "news",       # news results
}
Enter fullscreen mode Exit fullscreen mode

Pass user-agent and query params

Pass user-agent to request headers and, pass query params while making a request.

You can read more in-depth about this topic in the article below about why it's a good idea to pass user-agent to request header.

Article No Longer Available

After request is made, then we receive a response which will be decoded via .text.

html = requests.get("https://search.naver.com/search.naver", params=params, headers=headers).text
Enter fullscreen mode Exit fullscreen mode

Save HTML locally 

with open(f"{params['query']}_naver_news.html", mode="w") as file:
    file.write(html)

# output file will be minecraft_naver_news.html
Enter fullscreen mode Exit fullscreen mode

Find correct selectors or HTML elements

Get a CSS selector of the container with all needed data such as title, link, etc

Gif that shows which selectors being used as a container

for news_result in soup.select(".list_news .bx"):
    # further code
Enter fullscreen mode Exit fullscreen mode

Get a CSS selector for title, link, etc. that will be used in extracting part

Gif that shows which selectors being used for title, link, snippet, thumbnail and other data

for news_result in soup.select(".list_news .bx"):

    # hey, news_results, grab TEXT from every element with ".news_tit" selector 
    title = news_result.select_one(".news_tit").text

    # hey, news_results, grab href (link) from every element with ".news_tit" selector 
    link = news_result.select_one(".news_tit")["href"]
    # other elements..
Enter fullscreen mode Exit fullscreen mode

Extract data 

import lxml, json
from bs4 import BeautifulSoup

with open("minecraft_naver_news.html", mode="r") as html_file:
    html = html_file.read()
    soup = BeautifulSoup(html, "lxml")

    news_data = []

    for news_result in soup.select(".list_news .bx"):
        title = news_result.select_one(".news_tit").text
        link = news_result.select_one(".news_tit")["href"]
        thumbnail = news_result.select_one(".dsc_thumb img")["src"]
        snippet = news_result.select_one(".news_dsc").text

        press_name = news_result.select_one(".info.press").text
        news_date = news_result.select_one("span.info").text

        news_data.append({
            "title": title,
            "link": link,
            "thumbnail": thumbnail,
            "snippet": snippet,
            "press_name": press_name,
            "news_date": news_date
        })

    print(json.dumps(news_data, indent=2, ensure_ascii=False))
Enter fullscreen mode Exit fullscreen mode

Now lets see what is going on here.

Import bs4, lxml and json libraries 

import lxml, json
from bs4 import BeautifulSoup
Enter fullscreen mode Exit fullscreen mode

Open saved HTML file and pass to BeautifulSoup()

Open saved HTML file and change the mode from writing (mode="w") to reading (mode="r") and pass it to BeautifulSoup() so it can extract elements, and assigned "lxml" as a HTML parser.

with open("minecraft_naver_news.html", mode="r") as html_file:
    html = html_file.read()            # reading 
    soup = BeautifulSoup(html, "lxml")
Enter fullscreen mode Exit fullscreen mode

Create list() to temporary store the data 

news_data = []
Enter fullscreen mode Exit fullscreen mode

Iterate over container

By container I mean CSS selector that wraps other elements such as title, link, etc. inside itself with all the needed data, and extract it.

# news_data = []

for news_result in soup.select(".list_news .bx"):
    title = news_result.select_one(".news_tit").text
    link = news_result.select_one(".news_tit")["href"]
    thumbnail = news_result.select_one(".dsc_thumb img")["src"]
    snippet = news_result.select_one(".news_dsc").text

    press_name = news_result.select_one(".info.press").text
    news_date = news_result.select_one("span.info").text
Enter fullscreen mode Exit fullscreen mode

Append extracted data as a dictionary to earlier created list() 

news_data.append({
    "title": title,
    "link": link,
    "thumbnail": thumbnail,
    "snippet": snippet,
    "press_name": press_name,
    "news_date": news_date
})
Enter fullscreen mode Exit fullscreen mode

Print collected data

Print the data using json.dumps(), which in this case is just for pretty printing purpose.

print(json.dumps(news_data, indent=2, ensure_ascii=False))

# part of the output
'''

  {
    "title": "Xbox, 11월부터 블록버스터 게임 연이어 출시",
    "link": "http://www.gameshot.net/common/con_view.php?code=GA617793ce93c74",
    "thumbnail": "https://search.pstatic.net/common/?src=https%3A%2F%2Fimgnews.pstatic.net%2Fimage%2Forigin%2F5739%2F2021%2F10%2F26%2F19571.jpg&type=ofullfill264_180_gray&expire=2&refresh=true",

    "press_name": "게임샷",
    "news_date": "6일 전"
  }
  # other results...
]
'''
Enter fullscreen mode Exit fullscreen mode

Call newly added data 

for news in news_data:
    title = news["title"] 
    # link, snippet, thumbnail.. 
    print(title)

    # prints all titles that was appended to the list()
Enter fullscreen mode Exit fullscreen mode

Full Code

Have a look at third function that will make an actual request to Naver search with passed query parameters. Test in the online IDE yourself.

import lxml, json, requests
from bs4 import BeautifulSoup


headers = {
    "User-Agent":
    "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.102 Safari/537.36 Edge/18.19582"
}

params = {
    "query": "minecraft",
    "where": "news",
}


# function that parses content from local copy of html
def extract_news_from_html():
    with open("minecraft_naver_news.html", mode="r") as html_file:
        html = html_file.read()

        # calls naver_parser() function to parse the page
        data = naver_parser(html)

        print(json.dumps(data, indent=2, ensure_ascii=False))


# function that makes an actual request
def extract_naver_news_from_url():
    html = requests.get("https://search.naver.com/search.naver", params=params, headers=headers)

    # calls naver_parser() function to parse the page
    data = naver_parser(html)

    print(json.dumps(data, indent=2, ensure_ascii=False))


# parser that accepts html argument from extract_news_from_html() or extract_naver_news_from_url()
def naver_parser(html):
    soup = BeautifulSoup(html.text, "lxml")

    news_data = []

    for news_result in soup.select(".list_news .bx"):
        title = news_result.select_one(".news_tit").text
        link = news_result.select_one(".news_tit")["href"]
        thumbnail = news_result.select_one(".dsc_thumb img")["src"]
        snippet = news_result.select_one(".news_dsc").text

        press_name = news_result.select_one(".info.press").text
        news_date = news_result.select_one("span.info").text

        news_data.append({
            "title": title,
            "link": link,
            "thumbnail": thumbnail,
            "snippet": snippet,
            "press_name": press_name,
            "news_date": news_date
        })

    return news_data
Enter fullscreen mode Exit fullscreen mode

Using Naver News Results API

As an alternative, you can achieve the same by using SerpApi. SerpApi is a paid API with a free plan.

The difference is that there's no need to code the parser from scratch and maintain it overtime (if something will be changed in the HTML), figure out what selectors to use, and how to bypass blocks from search engines.

Install SerpApi library

pip install google-search-results
Enter fullscreen mode Exit fullscreen mode

Example code to integrate:

from serpapi import GoogleSearch
import os, json

params = {
    "api_key": os.getenv("API_KEY"),
    "engine": "naver",
    "query": "Minecraft",
    "where": "news"
}

search = GoogleSearch(params)  # where extraction happens
results = search.get_dict()    # where structured json appears 

news_data = []

for news_result in results["news_results"]:
    title = news_result["title"]
    link = news_result["link"]
    thumbnail = news_result["thumbnail"]
    snippet = news_result["snippet"]
    press_name = news_result["news_info"]["press_name"]
    date_news_poseted = news_result["news_info"]["news_date"]

    news_data.append({
        "title": title,
        "link": link,
        "thumbnail": thumbnail,
        "snippet": snippet,
        "press_name": press_name,
        "news_date": date_news_poseted
    })

print(json.dumps(news_data, indent=2, ensure_ascii=False))
Enter fullscreen mode Exit fullscreen mode

Let's how this code works.

Import serpapi, os, json libraries 

from serpapi import GoogleSearch
import os
import json  # in this case used for pretty printing
Enter fullscreen mode Exit fullscreen mode

os library stands for operating system (miscellaneous operating system interfaces), and os.getenv(SECRET_KEY) return the value of the environment variable key if it exists.

Define search parameters

Note this parameters will be different depending on what "engine" you're using (except, in this case, "api_key", "query").

params = {
    "api_key": os.getenv("API_KEY"),   # API key that being stored in the environment variable
    "engine": "naver",                 # search engine
    "query": "Minecraft",              # search query
    "where": "news"                    # news results filter
    # other parameters
}
Enter fullscreen mode Exit fullscreen mode

Create list() to temporary store the data 

news_data = []
Enter fullscreen mode Exit fullscreen mode

Iterate over each ["news_resutlts"], and store to the news_data list().

The difference here is that instead of calling some CSS selectors, we're extracting data from the dictionary (provided from SerpApi) by their key.

for news_result in results["news_results"]:
    title = news_result["title"]
    link = news_result["link"]
    thumbnail = news_result["thumbnail"]
    snippet = news_result["snippet"]
    press_name = news_result["news_info"]["press_name"]
    date_news_poseted = news_result["news_info"]["news_date"]

    news_data.append({
        "title": title,
        "link": link,
        "thumbnail": thumbnail,
        "snippet": snippet,
        "press_name": press_name,
        "news_date": date_news_poseted
    })
Enter fullscreen mode Exit fullscreen mode

Print collected data via json.dumps() to see the output 

print(json.dumps(news_data, indent=2, ensure_ascii=False))
