Detailed Description

Simplifies obtaining an OAuth 2.0 Bearer Access Token.

Create an Instance() and initialize this class with it.
Call step_1() to get the URI your user has to visit.
Get the authorization code from your user.
Call step_2() with the code.

Example:

mastodonpp::Instance instance{"example.com", {}};
mastodonpp::Instance::ObtainToken token{instance};
auto answer{token.step1("Good program", "read:blocks read:mutes", "")};
if (answer)
{
    std::cout << "Please visit " << answer << "\nand paste the code: ";
    std::string code;
    std::cin >> code;
    answer = access_token{token.step2(code)};
    if (answer)
    {
        std::cout << "Success!\n";
    }
}

Member Function Documentation

◆ step_1()

answer_type mastodonpp::Instance::ObtainToken::step_1	(	string_view	client_name,
		string_view	scopes,
