I mean, selenium is not for web scraping(it's mostly used for automating web app testing). If you can reverse engineer the API, like in this video, Scrapy is more than enough.

This took me 2 days to figure out. If you're having trouble with json.loads(), I found out that the json data i scraped was actually a byte string type, and so i had to decode it BEFORE using json.loads. So where he had (9:47) *raw_data = response.body* replace with: *raw_data = response.body.decode("utf-8")* then continue on with: *data = json.loads(raw_data)* TO CHECK IF YOU NEED TO DO THIS, RUN THIS TEST: *raw_data = repr(response.body)* #repr() is a built in function that (1) turns python objects into printable objects, so you can see what you're dealing with and (2) in my case, if it prints out your object, you can find out if you have a byte string because you will get a 'b' infront of your string. *print(raw_data)* output>>> b'{ {data:...}, otherdata: [{...},{...}] }' if you have this b, use the method I described above. Hope I saved someone time, stackoverflow doesn't have a question for this yet (:
@chris - Good Catch! Short answer: replace response.body.decode("utf-8") with response.text Detailed answer: Let's understand text and body response.body contains the raw response without any decoding response.text contains the decoded response text as string In this video, response.body worked because there are no special decoding required Your method is correct. Even better approach would be use response.text as it actually is TextResponse which is encoding aware object. Bonus tip: install ipython and you will have a much better python console Good luck!

I followed along all your videos to be able to scrape a javascript generated webpage, but the data I want to scrape isn't in the XHR tab. Any suggestions sir ?
Thank you for the easy to follow videos done in an calm unhurried manner. I notice you used VSCode for part of the work and CMD for running Scrapy. I found it extremely difficult to load Scrapy into VSCode even with a virtual environment. I could not run it in the VSCode terminal. How did you do it?
I work on scrapy a lot so I have it installed at the system level ("pip install scrapy" at cmd with admin rights). Just saves me a few steps. When I have to distribute the code, I always create a virtual environment and use scrapy inside it If I want to use VS Code terminal, I just use the bottom left area where the python environment in use is listed, click it, and change it to set to the current virtual environment.
@@codeRECODE Thank you for responding so quickly. I was under the impression that Scrapy could run in VSCode just like BS. I solved the issue after watching your video many times over and reading up numerous other sites. What I had failed to comprehend was Scrapy has to be run in the Anaconda cmd environment not within a VSCode notebook. VSCode is just an editor being used to create the spider file. Your use of ntschools.py file in C:\Users\Work also confused me. I have now created my first Scrapy spider and can follow your videos better. Thanks keep up the good work. Scrapy refused to install at the system level. I had to use Anaconda.

Oh, I understand the confusion. I removed that part to keep the video short. Anyways, you can make it quick and easy by following these steps. pip install scraper-helper This library contains some useful functions that I created for my personal use and later made it open source. Once you have this installed, you can use the headers that you copied directly without formatting. Simply use the function get_dict() and send the headers in a triple-quoted string: headers = scraper_helper.get_dict(''' accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed- accept-encoding: gzip, deflate, br accept-language: en-GB,en;q=0.9 ''') It will also take care of cleaning up unwanted headers like cookies, content-length etc. Good luck
Hi sir, I have one question about not this tutorial. I want to fetch multiple different domains having the same page structure with a single spyder. How I can achieve this ? Please help
hi, great video but sadly this will not work if the site does some hashing/encrypting of their API. for eg, a token has to be attached as the header and the token can only be achieved through some kind of computation done by the webpage
If your browser can handle encryption, hashing, you can do that with Scrapy too. Most of the time, they will just send some unique key which you have to send in the next request. If you don't have time to examine how it is working, you can use splash/selenium or something similar and save time. It will be faster to code but slower in execution. If you do figure out APIs, the scrapes are going to be very fast, especially when you want to get millions of items every day. Finally, just think of it as another tool in your arsenal. Use the one that suits the problem at hand :-) Good luck!
Hello, Mr Upendra. Every time I start to scrape, my data usage reaches its limit too fast. What is your data plan? I mean, How many GBs are you allowed to use per day?
It's really hard to calculate how many GBs your project is going to consume. If you can probably run your project on any of the cloud services. For any serious work, I would suggest to get a broadband connection with no data cap.

Create a regular scrapy request for the url that contains the json data. In the Call back method (for example, parse) you can access the json directly using response.json() in the newer versions
Scraping OTT is almost impossible due to technical reasons -as they have multiple layers of defenses to stop privacy, AND legal reasons. I am not going to attempt it for sure :-)
HI, I need your help. I am trying to scrape details from the e-commerce site www.banggood.com, the price is ajax loaded and I cannot retrieve it with scrappy then I tried to get the ajax request manually as you teach in the video but I cannot find the exact path for the request. Could you please make a video on this particular website (to find ajax request manually). Your help will be more appreciable. you can choose any category for scraping details. @Code / RECODE
In fact I followed your steps into the XHR and 1. It does not show accept.json (but the site is run by JS which I checked by the hack shown by you here) 2. It also says 'eval' not allowed on the site (not sure what that means) - it shows no file being generated as you have shown for this site. what could be happening here? I am trying to sort all my connections by the total number of reactions their posts have got. Can u help with a suggestion for coding this? thanks
I am attaching the link to the code. I just tried it and it works. Make sure that you run this with *scrapy runspider **ntschools.py* , not like a python script. Source: gist.github.com/eupendra/7900849c56872925635d0c6c6b8f78f5
@@codeRECODE Thanks for the quick revert. What I forgot to mention is I was trying to use your code on LinkedIn. Does it have excessive privacy policies because of which it is not showing any Json file being generated? Any help appreciated.
While CSRFtoken and sessions can be handled, I do agree that this technique does not work everywhere. However, this should be the first thing that we should try. Rendering using Selenium/Playwright should be the last resort. Even after that, many websites will not work, and there will be no workaround. 🙂

@@sunilghimire6990 It looks like you are either not passing the Headers in the request OR something is wrong with the user-agent part of the header dictionary OR the header dictionary itself is not correctly formatted. Here are a few other things I can suggest: 1. You are using extract(), which is the same as getall() This is confusing and that's why it is outdated now. 2. Probably you are using "scrapy CRAWL" to run the spider. What I have created here is a standalone spider which needs to be run using "scrapy runspider" 3. Take up my free course to get the basics clear. I am sure it will help you. Here is the coderecode.com/scrapy-crash-course 4. Once you register for the free course, you will find the complete source code that you can run.

Hey. I wanted to scrape number of comments of each game in the following link (fitgirl-repacks.site/all-my-repacks-a-z/). But I can't find it anywhere in the network tab. Yes the html without JS provides a number of comments with it but it is outdated one.
it's there! Here is how to find it. Open the site, press F12, go to the Network tab and open any listing. On the top, you will see something like 238 comments. Now, make sure that your focus is on the Network tab and press CTRL F. Now search for this number 238. You will quite a few results and one of them will be a .js file that will have this data. You will note that this comes from a third-party commenting system. Reminder - Getting this data using web scraping may not be legal. I do not give advice on what is legal and what is not. What I explained is only for learning how websites work. Good luck!

This took me 2 days to figure out. If you're having trouble with json.loads(), I found out that the json data i scraped was actually a byte string type, and so i had to decode it BEFORE using json.loads. So where he had (9:47)
*raw_data = response.body*
replace with: *raw_data = response.body.decode("utf-8")*
then continue on with: *data = json.loads(raw_data)*
TO CHECK IF YOU NEED TO DO THIS, RUN THIS TEST:
*raw_data = repr(response.body)* #repr() is a built in function that (1) turns python objects into printable objects, so you can see what you're dealing with and (2) in my case, if it prints out your object, you can find out if you have a byte string because you will get a 'b' infront of your string.
*print(raw_data)*
output>>> b'{ {data:...}, otherdata: [{...},{...}] }'
if you have this b, use the method I described above. Hope I saved someone time, stackoverflow doesn't have a question for this yet (:

Short answer: replace response.body.decode("utf-8") with response.text
Detailed answer:
Let's understand text and body
response.body contains the raw response without any decoding
response.text contains the decoded response text as string
In this video, response.body worked because there are no special decoding required

accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-
accept-encoding: gzip, deflate, br
accept-language: en-GB,en;q=0.9
''')
It will also take care of cleaning up unwanted headers like cookies, content-length etc. Good luck

Hi sir, I have one question about not this tutorial. I want to fetch multiple different domains having the same page structure with a single spyder. How I can achieve this ? Please help
If same structure means same selectors for all those domains, just add them to start_urls or create a crawl spider.
hi, great video but sadly this will not work if the site does some hashing/encrypting of their API. for eg, a token has to be attached as the header and the token can only be achieved through some kind of computation done by the webpage
If your browser can handle encryption, hashing, you can do that with Scrapy too. Most of the time, they will just send some unique key which you have to send in the next request.
If you don't have time to examine how it is working, you can use splash/selenium or something similar and save time. It will be faster to code but slower in execution.
If you do figure out APIs, the scrapes are going to be very fast, especially when you want to get millions of items every day.
Finally, just think of it as another tool in your arsenal. Use the one that suits the problem at hand :-)
Good luck!
Hello, Mr Upendra. Every time I start to scrape, my data usage reaches its limit too fast. What is your data plan? I mean, How many GBs are you allowed to use per day?
It's really hard to calculate how many GBs your project is going to consume. If you can probably run your project on any of the cloud services.
For any serious work, I would suggest to get a broadband connection with no data cap.
@@codeRECODE Thank You, Mr Upendra. I would like to know what data plan you use. What is your daily Data Limit?

Hi Sir,
How can we scrape json data from a website using scrapy.
Create a regular scrapy request for the url that contains the json data. In the Call back method (for example, parse) you can access the json directly using response.json() in the newer versions
@@codeRECODE hi sir have you posted any video on it?
Can we scrape any dynamic website using this method?
Short answer - No. There are multiple techniques to scrape dynamic websites. Every site is different and would need a different technique.
I have been trying to find a webscraper which will work on OTT platforms. Your method didn't gave me any results. I need help.
Scraping OTT is almost impossible due to technical reasons -as they have multiple layers of defenses to stop privacy, AND legal reasons. I am not going to attempt it for sure :-)
HI,

great video.Thanks you so much.

In fact I followed your steps into the XHR and 1. It does not show accept.json (but the site is run by JS which I checked by the hack shown by you here) 2. It also says 'eval' not allowed on the site (not sure what that means) - it shows no file being generated as you have shown for this site.
what could be happening here?
I am trying to sort all my connections by the total number of reactions their posts have got.

i need help regarding how to approach client for webscrapping project
I would be including some tips in my upcoming courses and videos
this is API scraping. some websites use csrftoken and sessions in their API, this makes the website nearly impossible to scrape from API.
While CSRFtoken and sessions can be handled, I do agree that this technique does not work everywhere.
However, this should be the first thing that we should try. Rendering using Selenium/Playwright should be the last resort.
Even after that, many websites will not work, and there will be no workaround. 🙂

@@sunilghimire6990
It looks like you are either not passing the Headers in the request OR something is wrong with the user-agent part of the header dictionary OR the header dictionary itself is not correctly formatted.
Here are a few other things I can suggest:
1. You are using extract(), which is the same as getall() This is confusing and that's why it is outdated now.
2. Probably you are using "scrapy CRAWL" to run the spider. What I have created here is a standalone spider which needs to be run using "scrapy runspider"
3. Take up my free course to get the basics clear. I am sure it will help you. Here is the coderecode.com/scrapy-crash-course
4. Once you register for the free course, you will find the complete source code that you can run. If you face any problem, you can attach screenprint and code in the comments in my course and I will surely help in detail

Hey. I wanted to scrape number of comments of each game in the following link (fitgirl-repacks.site/all-my-repacks-a-z/). But I can't find it anywhere in the network tab. Yes the html without JS provides a number of comments with it but it is outdated one.
it's there! Here is how to find it. Open the site, press F12, go to the Network tab and open any listing. On the top, you will see something like 238 comments. Now, make sure that your focus is on the Network tab and press CTRL F. Now search for this number 238. You will quite a few results and one of them will be a .js file that will have this data.
You will note that this comes from a third-party commenting system.
Reminder - Getting this data using web scraping may not be legal. I do not give advice on what is legal and what is not. What I explained is only for learning how websites work. Good luck!
