Quickstart

The following shows the code that you'll run in the google/cloud/recaptchaenterprise/quickstart/ directory, which should give you a taste of the reCAPTCHA Enterprise API C++ client library API.

 #include "google/cloud/recaptchaenterprise/v1/recaptcha_enterprise_client.h"
#include "google/cloud/project.h"
#include <iostream>

int main(int argc, char* argv[]) try {
  if (argc != 2) {
    std::cerr << "Usage: " << argv[0] << " project-id\n";
    return 1;
  }

  namespace recaptchaenterprise = ::google::cloud::recaptchaenterprise_v1;
  auto client = recaptchaenterprise::RecaptchaEnterpriseServiceClient(
      recaptchaenterprise::MakeRecaptchaEnterpriseServiceConnection());

  auto const project = google::cloud::Project(argv[1]);
  for (auto r : client.ListKeys(project.FullName())) {
    if (!r) throw std::move(r).status();
    std::cout << r->DebugString() << "\n";
  }

  return 0;
} catch (google::cloud::Status const& status) {
  std::cerr << "google::cloud::Status thrown: " << status << "\n";
  return 1;
}
