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

Question

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

使用cURL之类的库（或其他许多可用的库）来获取URL，然后将结果存储在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.
