Dialogflow ES API C++ Client Library

An idiomatic C++ client library for the Dialogflow ES API, a service to build conversational interfaces (for example, chatbots, and voice-powered apps and devices). There are two editions of Dialogflow, this library supports the ES edition.

While this library is GA, please note Google Cloud C++ client libraries do not follow Semantic Versioning.

Quickstart

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

#include "google/cloud/dialogflow_es/agents_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 dialogflow_es = ::google::cloud::dialogflow_es;
  auto client =
      dialogflow_es::AgentsClient(dialogflow_es::MakeAgentsConnection());

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

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

Main classes

This library offers multiple *Client classes, which are listed below. Each one of these classes exposes all the RPCs for a gRPC service as member functions of the class. This library groups multiple gRPC services because they are part of the same product or are often used together. A typical example may be the administrative and data plane operations for a single product.

The library also has other classes that provide helpers, configuration parameters, and infrastructure to mock the *Client classes when testing your application.
