How to get items from headers by learning from initiators and using request python? - fingerprintjs2

I am trying to get the fingerprint as can be seen from this snapshot.
I tried searching for the fingerprint but it's not in the response or cookies. I am wondering how this fingerprintjs works so that I can imitate and return the fingerprint item.
The website is https://alfagift.id/
When you take a look into network, especially categories, there's a preflight and an xhr where it is initiated by https://alfagift.id/_nuxt/ca268e7.js
I've tried doing a requests
resp=requests.get(" https://alfagift.id/")
resp.cookies
nothing seems to be returning the fingerprint that's needed.
Can anyone show me how you can get the fingerprint?

HTTP Request fails when using the same parameters and the same environment

I'm trying to fetch data from a website (https://gesetze.berlin.de/bsbe/search). Using Mozilla, I've taken a look at the network analysis. Usually, I'm just messing around with the parameters of the POST-Request to see how I might influence the response of the server. But when I simply re-send the request (making no changes at all), I'm getting HTTP-response 500. The server answer states as message: security_notAuthenticated.
Can anyone explain that behaviour? The request is done by the same PC, the same browser in the same session, and there is no login function on that website. Pictures shown below.
Picture 1 - Code 200
Picture 2 - Code 500
The response security_notAuthenticated indicates, that your way of repeating the request omits some authentication-related information.
When I repeat the request, using Mozilla Firefox's "Resend" or "Edit and resend" function, the Cookie header is not sent with the request. Although it occurs in the editable header list when using "Edit and resend" it's missing when watching the actual sent request. I'm not sure whether this is a feature or a bug.
When using Firefox's "Use as Fetch in Console" function, the header will automatically be included and you still have the ability to change the headers and the body. The fetch API is a web standard and some introductory material about fetch can be found on MDN.
If you want to do custom requests, in the browser, fetch is a good option.
In other environments and languages you usually use some HTTP client (just search the web for "...your language... http request" or similar, you will find something).

Observe http request and simulate the same request in code

Is there a way to observe a http request in the browser and save that request (header data and parameters) and simulate the same request in code?
What I want is to "simulate" a browser in my project, to get the same response back like if the user is using a normal browser.
I don't know exactly how to ask the question correctly, but what I want is to simulate the authentification on some websites and scrape the same data as when I were in the browser.
What I wanted was to crawle a website, which is secured with authentification, using simple http-requests and build the request-header in my code. And it was not only about sending a POST-request with name + password, but also some other hidden parameters which are first generated when a user visits the website - on the clientside with javascript.
Maybe it is possible to understand the algorithm behind generating those hidden parameters, but it can take a long time because of the complexity.
The best way to crawle a website in a automated way without caring about the correct headers is to use a "headless" browser, which is nothing else then a normal browser without a GUI. You can control it in your code. A list of those headless browsers can be found here.
So no need for observing and recording the request and simulating it in code - just use a headless browser.

Request interrupted - Paw

No matter what I do, I always get this error on the console. It works on other machines, but not in mine. Postman works with the same service. How to solve?
Update: this bug has been now fixed in Paw 2.3.4. And we confirm that the workaround below wasn't resolving the "Request Interrupted" issue most users were having. You can update in Paw menu > Check for Updates…
One quick way to solve this is to go to the Paw menu > Preferences > HTTP and pick another HTTP library:
To be able to send exactly what users are entering (including any kind of headers, GET requests with a body) and display exactly what servers are returning (keeping the exact raw bytes, the order of headers) Paw has its own custom HTTP library that can do all this kind of stuff. Unfortunately, it's not yet as stable as standard libraries, hence the possibility to choose another alternative.

What will the RightSignature API send to my callback URL when a signer signs a document

When I send a one-off document to RightSignature via their API, I'm specifying a callback location in the XML document as specified in RightSignature's schema definition. I then get a signer-link value back from their API for the document. I display the HTML response from the signer-link URL in an iFrame on our website. When our user signs the document in this iFrame, which is rendering the responses from their website, I want their website to post to our callback location.
Can I do this with the RightSignature API and does it make sense?
So far, I'm only getting content in the iFrame that indicates that the signing was successful. The callback location does not seem to be getting called.
I got it solved just now. Basically, i was doing two things wrong first you have to go in RightSignature Account and set it there the CallBack url
Account > Settings > Advanced Settings
But the thing which RS is unable to mention to us that this url can not be of localhost, but it should be of https i mean like Live URL of your site like
https://stagingmysite.azurewebsites.net/User/CallBackFunction
And then in your CallBack just write these two lines and you will receive complete XML which would have the GUID and document status as well.
byte[] data = Request.BinaryRead(Request.TotalBytes);
string callBackXML = System.Text.Encoding.UTF8.GetString(data);
I found the answer with some help from the API team at RightSignature. I was using callback_location but what I really wanted is redirect_location. Their online documentation was difficult to follow and did not clearly point out the difference.
I got this working after a lot of trial and error.

Logging into a webpage via HTTP Request

So I have a webpage, ("http://data.terapeak.com/verify/") and I don't see any & tags in the URL so I am unaware how to post data to this. I need to do this via HTTPRequest rather than browser control. I am creating a double threaded batch searching program. I have already successfully made this using a single browser control but that wont allow for multi-threading, atleast with my current knowledge due to the fact that even when creating a new frmBrw that already exists it needs for me to set the threat apartment to single. If i set it to single, I am unable to have it send the data the the excel sheet I need both threads to access. I hope this is clear... The basic question is how can I log into this form via HTTP request.
This isn't going to be easy to answer without further details however I suspect you'll need to provide the variables via a HTTP POST request.
Can you successfully login to this page in your browser? If so, run a proxy tool such as fiddler and check the HTTP headers it makes to the server. You should see the form variables being passed over. You then need to mimic this in code.

Hope this gets you started
