Is it possible for postman(App not Chrome extension) scripts to open an external browser and fetch data from the website (In my case a Temp Pin) as a request parameter?
I did search on the web and didn't found any leads except that POSTMAN now supports opening external browser starting version 6.1.2.

TLDR: React app's API calls are returning with status code 200 but without body in response, happens only when accessing the web app from some browsers.
I have a React + Django application deployed using nginx and uwsgi on a single centOS7 VM.
The React app is served by nginx on the domain, and when users log in on the javascript app, REST API requests are made to the same nginx on a sub domain (ie: backend.mydomain.com), for things like validate token and fetch data.
This works on all recent version of Firefox, Chrome, Safari, and Edge. However, some users have complained that they could not log in from their work network. They can visit the site, so obviously the javascript application is served to them, but when they log in, all of the requests come back with status 200, except the response has an empty body. (and the log in requires few pieces of information to be sent back with the log in response to work).
For example, when I log in from where I am, I would get response with status=200, and a json object with few parameters in the body of the response.
But when one of the users showed me the same from their browser, they get Status=200 back, but the Response is empty. They are using the same version of browsers as I have. They tried both Firefox and Chrome with the same behaviours.
After finally getting hold of one of the user to send me some screenshots. I found the problem. In my browser that works with the site, the API calls to the backend had Referrer Policy set to strict-origin-when-cross-origin in the Headers. However on their browser, the same was showing up as no-referrer-when-downgrade.
I had not explicitly set the referrer policy so the browsers were using each of their default values, and it differed between different versions of browsers (https://developers.google.com/web/updates/2020/07/referrer-policy-new-chrome-default)
To fix this, I added add_header 'Referrer-Policy' 'strict-origin-when-cross-origin'; to the nginx.conf file and restarted the server. More details here: https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Referrer-Policy
The users who had trouble before can now access the site API resources after clearing cache in their browsers.
When I open a directory in Chrome such as:
file:///Users/me/desktop/
Does the chrome send a get request to OS to fetch the file?
I am using JA_Orisite template of joomla2.5 for my client, and unable to load jquery file "//ajax.googleapis.com/ajax/libs/jquery/1.7/jquery.min.js"(needed for menu and article scrollings, etc), This file was being loaded on localhost, when I transfered the site using akeeba backup and recovery process, after installation on server I am unable to load jquery.
Surprisingly, I was having file permission issues on server, once I set 777 to all the files of my site, Jquery file was also working properly.
As the first server is not providing me the expected speed and service, I have transfered the site to other hosting server, which is now giving the same problem of jquery, On this server too I tried to set the permissions to 777, and yet unable to load jquery files.
Rather than importing it from Google, you could always import a local version like so:
<?php
// load jQuery, if not loaded before
if(!JFactory::getApplication()->get('jquery')){
JFactory::getApplication()->set('jquery',true);
$document = JFactory::getDocument();
$document->addScript(JURI::root() . "templates/template_name/js/jquery.js");
}
?>
I want to know when I'm using IE8 open a website (like www.yahoo.com), which API will be called by IE8? so I can hook these API to capture which website that IE8 opening currently.
When you enter a URL into the browser, the browser (usually) makes an HTTP request to the server identified by the URL. To make the request, the IP address of the server is required, which is obtained by a DNS lookup of the host (domain) name.
Once the response -- usually containing HTML markup -- is received, the browser renders it to display the webpage.
More details available here: what happens when you type in a URL in browser
So, in the general case, no "API" request as such is made. (Technically speaking, you can think of the original HTTP request to the server as an API request). The sort of "API" request you presumably mean, however, is not made in this general case just described. Those requests happens when the JavaScript executing on the page makes an Ajax HTTP request (XmlHttpRequest) to the web server to carry out some operation.
I am not sure about IE8, but the "developer tools" feature of most modern browsers (including IE9 and IE10), would let you see the Ajax HTTP requests that the webpage made as it carried out different operations.
Hope this helps.
IE uses Microsoft's WinSock library API to interact with web servers.
You may want to look for a network monitoring/sniffing API, which you could use to examine HTTP requests, and determine the URLs the browser is using.
I am sending get httpwebrequests to the facebook graph api and all was working fine till I deployed to production server and now module that expects html/xml response is not working and when tested url in internet explorer, the save file dialog pops up and the file needs to be saved.
Other modules also send requests to the facebook graph but just differ in the form of requests so not sure what is going on here.
Any ideas appreciated
Edit:
Let me try and rephrase this. On my production server the httpwebrequest was not returning the correct result. So to Test it I copied the url http://graph.facebook.com/pepsi which is an example, should return the profile info viewable in the browser. The server has internet explorer v8 and I am not sure why it tries to download the file instead of displaying it in the browser. this is what is happening in my code and when I make a request to a different part of the api, then it works in my app but not in the browser
Your question is not very clear. From what I gather, you want the display the JSON response in a browser. Instead, you are being asked to download a file by the browser.
Well, this is normal behaviour. The response you get from Facebook would most likely have a MIME type of application/json. Most newer web browsers display the text in the browser itself. Some browsers, however don't know how to handle this content type and just ask you to download the file.
You mentioned that your module expects an html/xml response. Try changing this to application/json.
You also said that it works in your app but not in your browser. I don't know what you're making, but generally you wouldn't show raw json to the user in a browser, right?
