cpr library-Introduction


cpr is a modern HTTP library for C++, built for people.It is a simple wrapper around libcurl inspired by the python requests project.

Despite its name, libcurl's easy interface is anything but making mistakes misusing it is a common source of error which can be frustrating. Using the more expressive language facilities of C++11, this library captures the essence of making network calls into a few concise idioms.

C++ Requests is designed to be as simple and pleasant to use as possible. HTTP method through the primary API are for limited time and stateless.On the other hand,this library firmly believes that Resource Acquisition Is Initialization. Cleanup is as easy and intuitive as letting an object fall out of scope. You would not find any init() or close() methods here, and proper use of this library requires neither delete nor free.

Example of GET request:

Without using it can be more complicated and also less functional.
