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

While this library isGA, please note Google Cloud C++ client libraries donot followSemantic Versioning.

Quickstart

The following shows the code that you'll run in thegoogle/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 service as member functions of the class. This library groups multiple 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.
