Hello, guys,

I want to get content from a website, like:

https://example.com/data.txt

And let's say, data.txt has the following data:

data.txt

Hello, world!

And notice these lines from here:

oscfg.hpp

71] else if (cmd == "[login]") {
72] // Later...
73] } else {

Instead of that comment "Later...", I would like to insert code, which would cout out the contents of https://example.com/data.txt‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎

What I have tried:

You first need to download the data into a local file. It is then a simple matter to read and display the contents.

Depends on what C++ framework you are using: if it's a .NET project, then there is the WebClient Class (System.Net) | Microsoft Docs[^] which includes the WebClient.DownloadFile Method (System.Net) | Microsoft Docs[^] which does it all for you in two lines of code.

I use Replit. So what is the correct software for that? ( Well I know that Replit's PC is Linux, because that's how bash works. )

( Also not download a page, but cout out the contents ( I mean, store the HTML into a variable, and then use cout << html to cout ou the variable, in which the HTML is stored. ) )

Did you look at the class methods available?
DownloadString for example? Or DownloadData?
:sigh:

I think you're telling me how to do that in C#, if so, this is C++

You do realize that C++ can use .NET as well? Just change the code sample language in the documentation ...

You can find C++ sample at below location that is doing most of the job.

Simple C, C++ Program to download a file from internet URL | This is a ten line C, C++ program that connects to the internet and downloads the html source of a web page. The given program supports both http and https requests and works even if there [^]

Now, all you have to do is read the file in a buffer and cout it

Solution 3

You need to create a socket connection to the server, and use a GET request as described at HTTP Tutorial[^].
