Librerie e strumenti
I framework Cloud Endpoints per l'ambiente standard di App Engine
forniscono le seguenti librerie e strumenti:
Endpoints Frameworks è disponibile nel
Maven Central Repository
nel gruppo com.google.endpoints. Il file .jar di base obbligatorio si trova nell'elemento endpoints-framework. Per maggiori dettagli, consulta la documentazione Javadoc dell'API.
Lo strumento a riga di comando endpoints (per Linux) o endpoints.cmd (per Windows) che puoi utilizzare per generare bundle di librerie client e documenti di rilevamento, che consentono alle app per Android e ad altri tipi di applicazioni client di accedere alla tua API.
Scrivi l'applicazione client utilizzando la libreria client quando effettui chiamate
all'API.
Per iniziare
Per iniziare, segui il
tutorial
per configurare, eseguire il deployment e inviare richieste a un'API di esempio. Poi, torna a questa sezione per consultare le informazioni necessarie per configurare, eseguire il deployment e testare la tua API.
Migrazione dalla versione 1.0 di Endpoints
Se hai già sviluppato un backend API utilizzando la versione precedente di Endpoints, segui la guida alla migrazione per spostare la tua app alla versione 2.0 di Endpoints.

See\n[About Endpoints Frameworks](/endpoints/docs/frameworks/about-cloud-endpoints-frameworks)\nfor an architectural overview of Endpoints Frameworks.\n\nLibraries and tools\n-------------------\n\nCloud Endpoints Frameworks for the App Engine standard environment\nprovides the following libraries and tools:\n\n\n- The Endpoints Frameworks is available in the [Maven Central Repository](http://search.maven.org/) in the group `com.google.endpoints`. The base required `.jar` file is in the `endpoints-framework` artifact. See [API Javadoc](/endpoints/docs/frameworks/java/javadoc) for details.\n- The [`endpoints`](/endpoints/docs/frameworks/java/endpoints_tool) command-line tool (for Linux), or `endpoints.cmd` (for Windows) that you can use to generate client library bundles and [Discovery documents](https://developers.google.com/discovery/v1/reference/apis), which allow Android apps and other types of client applications to access your API.\n- The [Endpoints Frameworks Maven plugin](/endpoints/docs/frameworks/java/maven-endpoints-frameworks-plugin) and the [Endpoints Frameworks Gradle plugin](/endpoints/docs/frameworks/java/gradle-endpoints-frameworks-plugin), which you use to generate the following:\n - Client library bundles and Discovery documents.\n - [OpenAPI configuration files](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/2.0.md), which you use if you want [API management](/endpoints/docs/frameworks/java/adding-api-management) functionality such as monitoring, logging, and API key validation.\n\n| **Note:** Because the API backend is an App Engine application, developers can use services and features available in the App Engine standard environment, such as [Datastore](/appengine/docs/java/datastore) , [Cloud Storage](https://cloud.google.com/storage/docs/overview) , [Mail](/appengine/docs/java/mail) , [Url fetch](/appengine/docs/java/urlfetch) , [Task queues](/appengine/docs/java/taskqueue) , and so forth. And finally, by using App Engine for the backend, developers are freed from system admin work, load balancing, scaling, and server maintenance.\n\nRequirements\n------------\n\nTo use Endpoints Frameworks, follow the process shown in the\n[Tutorial](/endpoints/docs/frameworks/java/get-started-frameworks-java).\n\nYou need to know how to develop the client of your choice, such as JavaScript\nweb clients, or mobile clients, such as Android.\n| **Note:** You cannot call a Cloud Endpoints API directly from a [push task queue](/appengine/docs/standard/java/taskqueue#push_queues) or a [cron job](/appengine/docs/standard/java/config/cron#Java_calling_google_cloud_endpoints).\n\nDevelopment process\n-------------------\n\nThe general workflow for developing an application using\nEndpoints Frameworks is:\n\n1. Create your API project, and then write your API code.\n2. [Annotate](/endpoints/docs/frameworks/java/annotate-code) your API, so classes and client libraries are generated from it.\n3. Generate the OpenAPI configuration file and deploy it as described in the [Tutorial](/endpoints/docs/frameworks/java/get-started-frameworks-java).\n4. Optionally, [test your API locally](/endpoints/docs/frameworks/java/test-deploy#running_and_testing_api_backends_locally).\n5. [Deploy the API](/endpoints/docs/frameworks/java/test-deploy).\n6. [Generate the client library](/endpoints/docs/frameworks/java/gen_clients).\n7. Write your client application by using the client library when making calls to the API.\n\nGetting started\n---------------\n\nTo get started, follow the\n\n\n[Tutorial](/endpoints/docs/frameworks/java/get-started-frameworks-java)\n\nto configure, deploy, and send requests to a sample API. Then come back to this\nsection for the information you need to configure, deploy, and test your own\nAPI.\n\nMigrating from Endpoints version 1.0\n------------------------------------\n\nIf you've already developed an API backend using the previous version of\nEndpoints, follow the\n\n[Migration guide](/endpoints/docs/frameworks/java/migrating)\n\nto move your app to Endpoints version 2.0."]]
