kandi X-RAY | scrape Summary
A simple, higher level interface for Go web scraping. When scraping with Go, I find myself redefining tree traversal and other utility functions. This package is a place to put some simple tools which build on top of the Go HTML parsing library. For the full interface check out the godoc.

QUESTION
I'm following a tutorial https://docs.openfaas.com/tutorials/first-python-function/,
currently, I have the right image
...ANSWER
Answered 2022-Mar-16 at 08:10If your image has a latest tag, the Pod's ImagePullPolicy will be automatically set to Always. Each time the pod is created, Kubernetes tries to pull the newest image.
Try not tagging the image as latest or manually setting the Pod's ImagePullPolicy to Never.
If you're using static manifest to create a Pod, the setting will be like the following:
QUESTION
I'm trying to scrape this site:
https://noticias.caracoltv.com/colombia
At the end you can find a "Cargar Más" button, that brings more news. So far so good. But, when inspecting that element it says it loads a link like this: https://noticias.caracoltv.com/colombia?00000172-8578-d277-a9f3-f77bc3df0000-page=2, as seen here:
The thing is, if I enter this into my browser, I get the same news I get if I just call the original website. Because of this, the only way I'm seeing I would be able to scrape the website is to create a script that recursively clicks. The thing is I need news until 2019, so it doesn't seem very feasible.
Also, when checking the event listeners I see this:
But I'm not sure how can I use that to my advantage.
Am I missing something? Is there any way to access older news through a link (or an API would be even better, but I didn't find any call to an API).
I'm currently using Python to scrape, but I'm in the investigation stage, so there's no code to show that's meaningful. Thanks a lot!

QUESTION
The amount of data(number of pages) on the site keeps changing and I need to scrape all the pages looping through the pagination.
Website: https://monentreprise.bj/page/annonces
Code I tried:
...ANSWER
Answered 2022-Mar-15 at 10:29Because the condition if len(next_page)<1 is always False.
For instance I tried the url monentreprise.bj/page/annonces?Company_page=99999999999999999999999 and it gives the page 13 which is the last page
What you could try maybe is checking if the "next page" button is disabled
QUESTION
I am trying to scrape some review data from the Walmart site using Selenium in Python, but it connects this site for human verification. After inspecting this 'Press & Hold' button, somehow when I find the element, it comes out as an [object HTMLIFrameElement], not as a web element. And the element appears randomly inside any of the iframes, among 10 iframes. It can be checked using a loop, but, ultimately we can't take any action in selenium without a web element.
Though this verification also occurs as a popup, I was trying to solve it for this page first. Somehow I located the position of this button using the div as a webelement.
ANSWER
Answered 2021-Aug-20 at 15:27Here's my make-shift solution. The key is the release after 10 seconds and click again. This is how I was able to trick the captcha into thinking I held it for just the right amount of time (in my experiments, the captcha hold-down time is randomized and 10 seconds ensures enough time to fully-complete the captcha).
QUESTION
I want to download/scrape 50 million log records from a site. Instead of downloading 50 million in one go, I was trying to download it in parts like 10 million at a time using the following code but it's only handling 20,000 at a time (more than that throws an error) so it becomes time-consuming to download that much data. Currently, it takes 3-4 mins to download 20,000 records with the speed of 100%|██████████| 20000/20000 [03:48<00:00, 87.41it/s] so how to speed it up?
ANSWER
Answered 2022-Feb-27 at 14:37If it's not the bandwidth that limits you (but I cannot check this), there is a solution less complicated than the celery and rabbitmq but it is not as scalable as the celery and rabbitmq, it will be limited by your number of CPU.
Instead of splitting calls on celery workers, you split them on multiple processes.

QUESTION
I have a developer account as an academic and my profile page on twitter has Elevated on top of it, but when I use Tweepy to access the tweets, it only scrapes tweets from 7 days ago. How can I extend my access up to 2006?
This is my code:
...ANSWER
Answered 2022-Feb-22 at 12:25The Search All endpoint is available in Twitter API v2, which is represented by the tweepy.Client object (you are using tweepy.api).
The most important thing is that you require Academic research access from Twitter. Elevated access grants addition request volume, and access to the v1.1 APIs on top of v2 (Essential) access, but you will need an account and Project with Academic access to call the endpoint. There's a process to apply for that in the Twitter Developer Portal.

QUESTION
I'm deploying a spring-boot application and prometheus container through docker, and have exposed the spring-boot /actuator/prometheus endpoint successfully. However, when I enable prometheus debug logs, I can see it fails to scrape the metrics:
ANSWER
Answered 2022-Feb-07 at 22:37Ok, I think I found my problem. I made two changes:
First, I moved the contents of the web.config.file into the prometheus.yml file under the 'spring-actuator'. Then I changed the target to use the hostname for my backend container, rather than 127.0.0.1.
The end result was a single prometheus.yml file:
QUESTION
I am working on certain stock-related projects where I have had a task to scrape all data on a daily basis for the last 5 years. i.e from 2016 to date. I particularly thought of using selenium because I can use crawler and bot to scrape the data based on the date. So I used the use of button click with selenium and now I want the same data that is displayed by the selenium browser to be fed by scrappy. This is the website I am working on right now. I have written the following code inside scrappy spider.

Answered 2022-Jan-14 at 09:30The 2 solutions are not very different. Solution #2 fits better to your question, but choose whatever you prefer.

I've been struggling with this problem for sometime, but now I'm coming back around to it. I'm attempting to use selenium to scrape data from a URL behind a company proxy using a pac file. I'm using Chromedriver, which my browser uses the pac file in it's configuration.
I've been trying to use desired_capabilities, but the documentation is horrible or I'm not grasping something. Originally, I was attempting to webscrape with beautifulsoup, which I had working except the data I need now is in javascript, which can't be read with bs4.

Answered 2021-Dec-31 at 00:29If you are still using Selenium v3.x then you shouldn't use the Service() and in that case the key executable_path is relevant. In that case the lines of code will be:
