json to std::string in c++ from an URL.

Question

Hello all,

I want to implement something where I will get an URL which will be a link to JSON db, now I need to get the json from this URL and convert it to std:string in a c++ file. Is there any easy way to do this.

Answer 1

Use a library such as cURL (or one of many others available) to fetch the URL, and then store the result in an std::string.

Answer 2

If you are on Windows then there is no need to use cURL library - try the api call URLOpenBlockingStream. It is not hard to use and will download the JSON response from the server. JSON can be thought of as XML - it is structurally similar although there are noticeable syntactical differences. That said, it shouldn't be too hard to write a simple parser.
