## Configura un'API ottimizzata per l'edge PetStore
In questo tutorial, i comandi di esempio utilizzano valori segnaposto per valori IDs come l'ID API e l'ID della risorsa. Una volta completato il tutorial, sostituisci questi valori con valori personalizzati.
**Per configurare un'API ottimizzata per i bordi utilizzando PetStore AWS SDKs**
1. Utilizza il seguente esempio per creare un'entità `RestApi`:
------
#### [ JavaScript v3 ]
```
import {APIGatewayClient, CreateRestApiCommand} from "@aws-sdk/client-api-gateway";
(async function (){
const apig = new APIGatewayClient({region:"us-east-1"});
const command = new CreateRestApiCommand({
name: "Simple PetStore (JavaScript v3 SDK)",
description: "Demo API created using the AWS SDK for JavaScript v3",
version: "0.00.001",
binaryMediaTypes: [
'*']
});
try {
const results = await apig.send(command)
console.log(results)
} catch (err) {
console.error(Couldn't create API:\n", err)
}
})();
```
Una chiamata riuscita restituisce l'ID API e l'ID risorsa root dell'API in un output simile al seguente:
```
{
id: 'abc1234',
name: 'PetStore (JavaScript v3 SDK)',
description: 'Demo API created using the AWS SDK for node.js',
createdDate: 2017-09-05T19:32:35.000Z,
version: '0.00.001',
rootResourceId: 'efg567'
binaryMediaTypes: [ '*' ]
}
```
------
#### [ Python ]
```
import botocore
import boto3
import logging
logger = logging.getLogger()
apig = boto3.client('apigateway')
try:
result = apig.create_rest_api(
name='Simple PetStore (Python SDK)',
description='Demo API created using the AWS SDK for Python',
version='0.00.001',
binaryMediaTypes=[
'*'
]
)
except botocore.exceptions.ClientError as error:
logger.exception("Couldn't create REST API %s.", error)
raise
attribute=["id","name","description","createdDate","version","binaryMediaTypes","apiKeySource","endpointConfiguration","disableExecuteApiEndpoint","rootResourceId"]
filtered_result ={key:result[key] for key in attribute}
print(filtered_result)
```
Una chiamata riuscita restituisce l'ID API e l'ID risorsa root dell'API in un output simile al seguente:
```
{'id': 'abc1234', 'name': 'Simple PetStore (Python SDK)', 'description': 'Demo API created using the AWS SDK for Python', 'createdDate': datetime.datetime(2024, 4, 3, 14, 31, 39, tzinfo=tzlocal()), 'version': '0.00.001', 'binaryMediaTypes': ['*'], 'apiKeySource': 'HEADER', 'endpointConfiguration': {'types': ['EDGE']}, 'disableExecuteApiEndpoint': False, 'rootResourceId': 'efg567'}
```
------
#### [ AWS CLI ]
```
aws apigateway create-rest-api --name 'Simple PetStore (AWS CLI)' --region us-west-2
```
L'output di questo comando è il seguente:
```
{
"id": "abcd1234",
"name": "Simple PetStore (AWS CLI)",
"createdDate": "2022-12-15T08:07:04-08:00",
"apiKeySource": "HEADER",
"endpointConfiguration": {
"types": [
"EDGE"
]
},
"disableExecuteApiEndpoint": false,
"rootResourceId": "efg567"
}
```
------
L'API creata ha un ID API che corrisponde a `abcd1234` e un ID risorsa root che corrisponde a `efg567`. Questi valori vengono utilizzati nella configurazione dell'API.
1. Quindi, viene aggiunta una risorsa figlio sotto la risorsa root e specificato il valore `RootResourceId` come valore della proprietà `parentId`. Nel seguente esempio si crea una risorsa `/pets` per l’API:
------
#### [ JavaScript v3 ]
```
import {APIGatewayClient, CreateResourceCommand } from "@aws-sdk/client-api-gateway";
(async function (){
const apig = new APIGatewayClient({region:"us-east-1"});
const command = new CreateResourceCommand({
restApiId: 'abcd1234',
parentId: 'efg567',
pathPart: 'pets'
});
try {
const results = await apig.send(command)
console.log(results)
} catch (err) {
console.log("The '/pets' resource setup failed:\n", err)
}
})();
```
Una chiamata riuscita restituisce informazioni sulla risorsa in un output simile al seguente:
```
{
"path": "/pets",
"pathPart": "pets",
"id": "aaa111",
"parentId": "efg567'"
}
```
------
#### [ Python ]
```
import botocore
import boto3
import logging
logger = logging.getLogger()
apig = boto3.client('apigateway')
try:
result = apig.create_resource(
restApiId='abcd1234',
parentId='efg567',
pathPart='pets'
)
except botocore.exceptions.ClientError as error:
logger.exception("The '/pets' resource setup failed: %s.", error)
raise
attribute=["id","parentId", "pathPart", "path",]
filtered_result ={key:result[key] for key in attribute}
print(filtered_result)
```
Una chiamata riuscita restituisce informazioni sulla risorsa in un output simile al seguente:
```
{'id': 'aaa111', 'parentId': 'efg567', 'pathPart': 'pets', 'path': '/pets'}
```
------
#### [ AWS CLI ]
```
aws apigateway create-resource --rest-api-id abcd1234 \
--region us-west-2 \
--parent-id efg567 \
--path-part pets
```
L'output di questo comando è il seguente:
```
{
"id": "aaa111",
"parentId": "efg567",
"pathPart": "pets",
"path": "/pets"
}
```
------
La risorsa `/pets` creata ha un ID risorsa che corrisponde a `aaa111`. Questo valore viene utilizzato nella configurazione dell'API.
1. Quindi, viene aggiunta una risorsa figlio sotto la risorsa `/pets`. Questa risorsa `/{petId}` ha un parametro di percorso per `{petId}`. Per fare di una parte di percorso un parametro di percorso, racchiudila tra parentesi graffe, `{ }`. Nel seguente esempio si crea una risorsa `/pets/{petId}` per l’API:
------
#### [ JavaScript v3 ]
```
import {APIGatewayClient, CreateResourceCommand } from "@aws-sdk/client-api-gateway";
(async function (){
const apig = new APIGatewayClient({region:"us-east-1"});
const command = new CreateResourceCommand({
restApiId: 'abcd1234',
parentId: 'aaa111',
pathPart: '{petId}'
});
try {
const results = await apig.send(command)
console.log(results)
} catch (err) {
console.log("The '/pets/{petId}' resource setup failed:\n", err)
}
})();
```
Una chiamata riuscita restituisce informazioni sulla risorsa in un output simile al seguente:
```
{
"path": "/pets/{petId}",
"pathPart": "{petId}",
"id": "bbb222",
"parentId": "aaa111'"
}
```
------
#### [ Python ]
```
import botocore
import boto3
import logging
logger = logging.getLogger()
apig = boto3.client('apigateway')
try:
result = apig.create_resource(
restApiId='abcd1234',
parentId='aaa111',
pathPart='{petId}'
)
except botocore.exceptions.ClientError as error:
logger.exception("The '/pets/{petId}' resource setup failed: %s.", error)
raise
attribute=["id","parentId", "pathPart", "path",]
filtered_result ={key:result[key] for key in attribute}
print(filtered_result)
```
Una chiamata riuscita restituisce informazioni sulla risorsa in un output simile al seguente:
```
{'id': 'bbb222', 'parentId': 'aaa111', 'pathPart': '{petId}', 'path': '/pets/{petId}'}
```
------
#### [ AWS CLI ]
```
aws apigateway create-resource --rest-api-id abcd1234 \
--region us-west-2 \
--parent-id aaa111 \
--path-part '{petId}'
```
L'output di questo comando è il seguente:
```
{
"id": "bbb222",
"parentId": "aaa111",
"path": "/pets/{petId}",
"pathPart": "{petId}"
}
```
------
La risorsa `/pets/{petId}` creata ha un ID risorsa che corrisponde a `bbb222`. Questo valore viene utilizzato nella configurazione dell'API.
1. Nei due passaggi seguenti, vengono aggiunti metodi HTTP alle risorse. In questo tutorial, vengono impostati i metodi per avere accesso aperto impostando `authorization-type` su `NONE`. Per consentire solo agli utenti autenticati di chiamare il metodo, puoi utilizzare i ruoli e le policy IAM, un'autorizzazione Lambda (nota in precedenza come autorizzazioni ad hoc) o un pool di utenti di Amazon Cognito. Per ulteriori informazioni, consulta [Controlla e gestisci l'accesso a REST APIs in API Gateway](apigateway-control-access-to-api.md).
Nel seguente esempio si aggiunge il metodo HTTP `GET` per la risorsa `/pets`:
------
#### [ JavaScript v3 ]
```
import {APIGatewayClient, PutMethodCommand } from "@aws-sdk/client-api-gateway";
(async function (){
const apig = new APIGatewayClient({region:"us-east-1"});
const command = new PutMethodCommand({
restApiId: 'abcd1234',
resourceId: 'aaa111',
httpMethod: 'GET',
authorizationType: 'NONE'
});
try {
const results = await apig.send(command)
console.log(results)
} catch (err) {
console.log("The 'GET /pets' method setup failed:\n", err)
}
})();
```
In caso di esito positivo, la chiamata restituisce il seguente output:
```
{
"apiKeyRequired": false,
"httpMethod": "GET",
"authorizationType": "NONE"
}
```
------
#### [ Python ]
```
import botocore
import boto3
import logging
logger = logging.getLogger()
apig = boto3.client('apigateway')
try:
result = apig.put_method(
restApiId='abcd1234',
resourceId='aaa111',
httpMethod='GET',
authorizationType='NONE'
)
except botocore.exceptions.ClientError as error:
logger.exception("The 'GET /pets' method setup failed: %s", error)
raise
attribute=["httpMethod","authorizationType","apiKeyRequired"]
filtered_result ={key:result[key] for key in attribute}
print(filtered_result)
```
In caso di esito positivo, la chiamata restituisce il seguente output:
```
{'httpMethod': 'GET', 'authorizationType': 'NONE', 'apiKeyRequired': False}
```
------
#### [ AWS CLI ]
```
aws apigateway put-method --rest-api-id abcd1234 \
--resource-id aaa111 \
--http-method GET \
--authorization-type "NONE" \
--region us-west-2
```
L'output di questo comando è il seguente:
```
{
"httpMethod": "GET",
"authorizationType": "NONE",
"apiKeyRequired": false
}
```
------
1. Nel seguente esempio si aggiunge il metodo HTTP `GET` alla risorsa `/pets/{petId}` e si imposta la proprietà `requestParameters` per passare il valore `petId` fornito dal client al backend:
------
#### [ JavaScript v3 ]
```
import {APIGatewayClient, PutMethodCommand } from "@aws-sdk/client-api-gateway";
(async function (){
const apig = new APIGatewayClient({region:"us-east-1"});
const command = new PutMethodCommand({
restApiId: 'abcd1234',
resourceId: 'bbb222',
httpMethod: 'GET',
authorizationType: 'NONE'
requestParameters: {
"method.request.path.petId" : true
}
});
try {
const results = await apig.send(command)
console.log(results)
} catch (err) {
console.log("The 'GET /pets/{petId}' method setup failed:\n", err)
}
})();
```
In caso di esito positivo, la chiamata restituisce il seguente output:
```
{
"apiKeyRequired": false,
"httpMethod": "GET",
"authorizationType": "NONE",
"requestParameters": {
"method.request.path.petId": true
}
}
```
------
#### [ Python ]
```
import botocore
import boto3
import logging
logger = logging.getLogger()
apig = boto3.client('apigateway')
try:
result = apig.put_method(
restApiId='abcd1234',
resourceId='bbb222',
httpMethod='GET',
authorizationType='NONE',
requestParameters={
"method.request.path.petId": True
}
)
except botocore.exceptions.ClientError as error:
logger.exception("The 'GET /pets/{petId}' method setup failed: %s", error)
raise
attribute=["httpMethod","authorizationType","apiKeyRequired", "requestParameters" ]
filtered_result ={key:result[key] for key in attribute}
print(filtered_result)
```
In caso di esito positivo, la chiamata restituisce il seguente output:
```
{'httpMethod': 'GET', 'authorizationType': 'NONE', 'apiKeyRequired': False, 'requestParameters': {'method.request.path.petId': True}}
```
------
#### [ AWS CLI ]
```
aws apigateway put-method --rest-api-id abcd1234 \
--resource-id bbb222 --http-method GET \
--authorization-type "NONE" \
--region us-west-2 \
--request-parameters method.request.path.petId=true
```
L'output di questo comando è il seguente:
```
{
"httpMethod": "GET",
"authorizationType": "NONE",
"apiKeyRequired": false,
"requestParameters": {
"method.request.path.petId": true
}
}
```
------
1. Utilizza l'esempio seguente per aggiungere la risposta del metodo 200 OK per il metodo `GET /pets`:
------
#### [ JavaScript v3 ]
```
import {APIGatewayClient, PutMethodResponseCommand } from "@aws-sdk/client-api-gateway";
(async function (){

Dopo aver creato la risposta di integrazione, l'API può interrogare gli animali domestici disponibili sul PetStore sito Web e visualizzare un singolo animale domestico con un identificatore specificato. Affinché l'API possa essere chiamata dai clienti, devi implementarla. Ti consigliamo di testare l'API prima di implementarla.
1. Nel seguente esempio si testa il metodo `GET /pets`:
------
#### [ JavaScript v3 ]
```
import {APIGatewayClient, TestInvokeMethodCommand } from "@aws-sdk/client-api-gateway";
(async function (){
const apig = new APIGatewayClient({region:"us-east-1"});
const command = new TestInvokeMethodCommand({
restApiId: 'abcd1234',
resourceId: 'aaa111',
httpMethod: 'GET',
pathWithQueryString: '/',
});
try {
const results = await apig.send(command)
console.log(results)
} catch (err) {
console.log("The test on 'GET /pets' method failed:\n", err)
}
})();
```
------
#### [ Python ]
```
import botocore
import boto3
import logging
logger = logging.getLogger()
apig = boto3.client('apigateway')
try:
result = apig.test_invoke_method(
restApiId='abcd1234',
resourceId='aaa111',
httpMethod='GET',
pathWithQueryString='/',
)
except botocore.exceptions.ClientError as error:
logger.exception("Test invoke method on 'GET /pets' failed: %s", error)
raise
print(result)
```
------
#### [ AWS CLI ]
```
aws apigateway test-invoke-method --rest-api-id abcd1234 /
--resource-id aaa111 /
--http-method GET /
--path-with-query-string '/'
```
------
1. Nel seguente esempio si testa il metodo `GET /pets/{petId}` con un valore `petId` che corrisponde a 3:
------
#### [ JavaScript v3 ]
```
import {APIGatewayClient, TestInvokeMethodCommand } from "@aws-sdk/client-api-gateway";
(async function (){
const apig = new APIGatewayClient({region:"us-east-1"});
const command = new TestInvokeMethodCommand({
restApiId: 'abcd1234',
resourceId: 'bbb222',
httpMethod: 'GET',
pathWithQueryString: '/pets/3',
});
try {
const results = await apig.send(command)
console.log(results)
} catch (err) {
console.log("The test on 'GET /pets/{petId}' method failed:\n", err)
}
})();
```
------
#### [ Python ]
```
import botocore
import boto3
import logging
logger = logging.getLogger()
apig = boto3.client('apigateway')
try:
result = apig.test_invoke_method(
restApiId='abcd1234',
resourceId='bbb222',
httpMethod='GET',
pathWithQueryString='/pets/3',
)
except botocore.exceptions.ClientError as error:
logger.exception("Test invoke method on 'GET /pets/{petId}' failed: %s", error)
raise
print(result)
```
------
#### [ AWS CLI ]
```
aws apigateway test-invoke-method --rest-api-id abcd1234 /
--resource-id bbb222 /
--http-method GET /
--path-with-query-string '/pets/3'
```
------
Dopo aver testato l'API correttamente, puoi implementarla in una fase.
1. Nel seguente esempio si implementa l’API in una fase denominata `test`. Quando implementi l'API in una fase, i chiamanti dell'API possono invocare l'API.
------
#### [ JavaScript v3 ]
```
import {APIGatewayClient, CreateDeploymentCommand } from "@aws-sdk/client-api-gateway";
(async function (){
const apig = new APIGatewayClient({region:"us-east-1"});
const command = new CreateDeploymentCommand({
restApiId: 'abcd1234',
stageName: 'test',
stageDescription: 'test deployment'
});
try {
const results = await apig.send(command)
console.log("Deploying API succeeded\n", results)
} catch (err) {
console.log("Deploying API failed:\n", err)
}
})();
```
------
#### [ Python ]
```
import botocore
import boto3
import logging
logger = logging.getLogger()
apig = boto3.client('apigateway')
try:
result = apig.create_deployment(
restApiId='ieps9b05sf',
stageName='test',
stageDescription='my test stage',
)
except botocore.exceptions.ClientError as error:
logger.exception("Error deploying stage %s.", error)
raise
print('Deploying API succeeded')
print(result)
```
------
#### [ AWS CLI ]
```
aws apigateway create-deployment --rest-api-id abcd1234 \
--region us-west-2 \
--stage-name test \
--stage-description 'Test stage' \
--description 'First deployment'
```
L'output di questo comando è il seguente:
```
{
"id": "ab1c1d",
"description": "First deployment",
"createdDate": "2022-12-15T08:44:13-08:00"
}
```
------
L'API può ora essere chiamata dai clienti. Puoi testare l'API inserendo l'URL `https://abcd1234.execute-api.us-west-2.amazonaws.com/test/pets` in un browser e sostituendo `abcd1234` con l'identificativo dell'API.
Per altri esempi su come creare o aggiornare un'API utilizzando AWS SDKs o AWS CLI, consulta [Azioni per l'utilizzo di API Gateway AWS SDKs](https://docs.aws.amazon.com/code-library/latest/ug/api-gateway_code_examples_actions.html).
## Automatizzazione della configurazione di un'API
Invece di creare la tua API step-by-step, puoi automatizzare la creazione e la pulizia delle AWS risorse utilizzando OpenAPI o Terraform per creare CloudFormation la tua API.
### Definizione di OpenAPI 3.0
Puoi importare una definizione OpenAPI in Gateway API. Per ulteriori informazioni, consulta [Sviluppa REST APIs utilizzando OpenAPI in API Gateway](api-gateway-import-api.md).
