I've never built a ff extension before and before I start I want some feedback on my idea to make sure its possible.
I want a firefox extension that allows me to supply a url with parameters in GET format, the extension would take the url, parse it, and submit the request as POST rather than GET.
Is this possible? and could someone give me some advice on how to start designing an extension? or point me at a tutorial?
You definitely can! Parsing the URL's can be done with any javascript library you can find such as parseUri or you can do it with the mozilla component nsIURLParser.
After that it is only a matter of actually executing the POST request with a XMLHttpRequest. I think that should be the easy part to do. The hard part will be getting up to speed with Firefox extension development. The Add-on Builder can set you with with a minimal Firefox extension as a building block.
Good Luck!
I don't know for sure, but as the Tamper Data plugin is able to manipulate HTTP request, it should be possible.
Have a look at the source code of the plugin to get some ideas.

I like that in Clojure I can read a webpage with (slurp url) the same way I read files stored on the local machine. But as soon as the URL contains a question mark followed by paramethers (https://www.google.ru/search?q=clojure) slurp returns error 400. Do I have to use another function? What is the simplest way?
I think you'll need to encode the = yourself. try this:
(slurp "https://google.ru/search?q%3Dclojure")
Also note there have been encoding issues with the underlying clojure.java.io/reader (what slurp is using under the covers) in the past so check your clojure version as well.
It is worth noting however that slurp is pretty basic and I wouldn't recommend relying on it for anything other than really basic stuff or as a convenience for working with URL's. If you need to pull information from URL's in actual code, I would suggest you look at clj-http, which is a full-featured http client library which will give you much more control than slurp.
I know that someone mean will probably close this question for being opinion, but the truth is, I'm not after opinion as such, but actual facts about the correct way and how to do this.
I've been searching around for quite a time and I'm still unclear as to what direction to take. It seems there are a billion* libraries that I could use, but I want to know what would be the correct, proper supported method of achieving this.
Essentially, I have a very simple requirement to list and download files from Sites on our Office 365 subscription to an iOS application.
Initially, I looked at the REST interface for Sharepoint and, from a browser, was able to easily perform a GET to our site and receive and receie a response with meta data about the file, for example:
https://mytenantid.sharepoint.com/_api/web/getfilebyserverrelativeurl('/MyFile/Here/Document.txt')
I could also retrieve JSON output instead of XML by specifying an Accept header of application/json using the POSTMAN REST client for Chrome.
So far, so easy. Just the authentication to do outside of the browser and that's it.
Phew!!
I started by looking at Basic authentication, but wasn't sure if this is the right way to do it and even if it would work?
On looking further, it seems that actually, using OAuth might be the way to go. Apparently, you can either do this yourself (no idea how), or use a library (ADAL?) from Microsoft? Unfortunately, this all looks half baked will very little documentation that seems to work. It also requires the use of CocoaPods and workspaces and isn't just a simple library that I can copy to my project and start using (a la SwiftyJSON). There also seems to be a lot of other libraries around too.
I should mention that I'm using Swift, so I've tried converting code from Objective C to Swift (unsuccessfully) too. Apparently I can't use "readWithCallback" with an argument list that the code tells me I should actually use -- even a sample application I downloaded had the same issue.
I've also tried using node.js with a script (not a Web Application) and the documentation and number of libraries available for that is almost worse.
Any assistance to achieve this really simple capability would be hugely appreciated -- it's been driving me nuts.
Many thanks,
D.
*this might be a slight exaggeration.
Office 365 has a RESTful API that you can use any programming language to authentication and integrate in your app.
Here is a simple example for iOS connected app to office 365. The sample shows how to do this in Objective C and SWIFT.

Enjoy :)
I have added the two lines of code to my project as described in this blog post.
However, as nothing different happens in the app itself, is there a way to test this behaviour and check it is working as expected? Is there a profile in instruments? Is there something I can print to the log in Xcode when a response is cached/cached response is used?
It just seems so simple to implement, I want to make sure it is actually having an effect on my app and that I won't have to implement a caching system myself.
Many thanks,
Sam
go offline right after you got the page and then reload the web view. the caching should take effect and the page should load I'd think
You can make sure so by analyzing HTTP traffic through a third party software like Charles.
Whenever app will make a request, HTTP Analyzer will pick the request made. If it is using cache, then same will be reflected in it.
(Check the contents of response to confirm the same)
Im trying to send some data to a form on a site were im a member using cURL, but when i look at the headers being sent, they seem to have been encrypted.
Is there a way i can get around this by making the computer / server visit the site and actual add the data to the inputs on the form and then hit submit, so that it would generate the correct data and post the form ?
You have got a few options:
reverse engineer the JavaScript that does the encryption (or possibly just encoding) process
get a browser engine (e.g. the Gecko engine), and add some scripting to it to fill in the forms and push the submit button - of course you would need JavaScript support within the page itself
parse the HTML using an HTML parser, feed the JavaScript in it to a JavaScript runtime with the correct libraries, fill in the "form" and hit the submit button
It's probably easiest to go for the first option. The JavaScript must be in the open to be able to be executed in the browser. But it may take some time to reverse-engineer as it is likely obfuscated.
You can use a framework to automate user interaction on the web pages, like Selenium.
This would enable you to not bother reverse engineering anything.
Selenium has binding in various languages, including Python and java.
Provided the javascript is visible on the website in question, you should be able to simply copy and paste their encryption routines to prepare the headers exactly as they do
A hacky fix if you can isolate the function that encodes the data you type in the form - is to use something like PyV8 to execute the JS inside python.
Use AutoHotKeyIt and actually have it use the Browser Normally. It can read from files, and do repetitive tasks infinitely. Also you can push a flag to make it only happen within that application, which means you can have it minimized and yet still preform the action.
You seem to be having issues with the problem of them encrypting the headers and such, so why not simply use that too your advantage? Your still pushing the same data in, but now your working around their system. With little to no side effect too you.
I've looked around but wasn't able to find what I was looking for. I'm looking for a way to automatically create short URLs displayed in the browser, not using a URL shortener. Basically I would like to re-create something like this:
idzr.org/1ptb
I upload screenshots to my server with "GrabUp" on a regular basis but it creates rather long URLs for example:
/2523e3c90d60f08e952215424e7c5d99.png
It's a bit annoying having to shorten them each time.
I have seen this method a lot lately with pretty much any file including html files. If this has been discussed already I'm sorry I'm posting it again. I just seem to be stuck.
Thanks in advance for any help & advice!
I don't know, what webserver do you use.
You write rule for rewrite
-- htaccess for Apache or equivalent for IIS
You push content to user thru your code, because browser doesn't know what content get from web server
-- use http header - MIME type
