VaultClient

The VaultClient object is the main object for this library. After it is constructed, it is provided to the various backends to complete requests. The constructor accepts the following options:

Name	Type	Description
config	VaultConfig&	Configuration
authentication strategy	AuthenticationStrategy&	Method for Vault authentication
http error callback	HttpErrorCallback	Callback for CURL errors

The caller must provide the config and authentication strategy. The http error callback is optional. The following example demonstrates how to properly construct the object:

HttpErrorCallback httpErrorCallback = [&](std::string err) {
  std::cout << err << std::endl;
};

auto config = VaultConfig::make().getConfig();
auto authStrategy = AppRole("role_id_guid", "secret_id_guid");
auto vaultClient = VaultClient(config, authStrategy, httpErrorCallback);
