I have gotten the authentication to work, now I am struggling with creating the correct xpath to the element I am looking for. When I fill in the information and run the script I am getting an empty array, I believe this is due to the fact that the script is not actually able to locate the correct class since the data is being pulled in from as a react app Result = session_requests.get(URL, headers = dict(referer = URL)) Result = session_requests.post(LOGIN_URL, data = payload, headers = dict(referer = LOGIN_URL)) I've looked at some guides online for writing my own python web scraper, and found one that I used to start the building blocks of the scraper with the following code: import requests The chat transcripts are behind a login, so the scraper will need to login/create a session then get the information What I've Done I am hoping to create a web scraper that will visit an olark chat transcript page, and scrape the chat from the page.
ANGULAR WEBSCRAPER CODE
I’m using the AngularJS $http service in the code, you can also just use jQuery $.ajax or plain XMLHttpRequest.News about the dynamic, interpreted, interactive, object-oriented, extensible programming language Python Current Events Now we are going to write our code that will mimic this POST request to login to the website. Have a look at the Request and Response Headers to get an idea of what is being sent to and from the server. After login, find the POST request in the queue and click on it.
ANGULAR WEBSCRAPER PASSWORD
Now login with username “gonehybrid” and password “password”. Make sure you tick “Preserve log” on the top. Open up the Developer Tools and go to the Network Tab. We will be writing code to login to this website and get a list of the dinners created by the logged in user. Let’s get startedįirst, we’ll need a website to scrape, for the purpose of this blog post I picked the open source website. So you might want to have a look at using that before you build the scraping yourself. Unfortunately, it didn't work with the website I was using, I kept getting an error when trying to record the login. The app I built was just for myself, so I didn't bother setting up a web service for it.īefore I decided to do the scraping in JavaScript I had actually looked at using import.io to create an API for the website with their tool.
ANGULAR WEBSCRAPER UPDATE
The best way to go about web scraping is creating a web service that handles the scraping so that when anything changes on the website you're scraping, you'll only have to update the web service. Since I was building a hybrid mobile app (which uses HTML/CSS/JavaScript), I figured I’d just try doing it all from JavaScript using AngularJS.
Remember: Web scraping can be illegal, so make sure you won’t get sued if you're using data that is not yours. To make it a little bit more complicated, I had to log in first to access the data I needed. Since that website didn’t expose an API to get the data, I needed to scrape it. I was working on a mobile app that needed to get data from a website. 12 January 2015 JavaScript, AngularJS, Web Scraping
