Crea un connettore personalizzato e una connessione
Questa pagina descrive come creare una specifica OpenAPI per un servizio web e poi creare un connettore personalizzato e una connessione per questo connettore.
Prima di creare un connettore personalizzato, devi creare una specifica OpenAPI per il servizio web.
Crea una specifica OpenAPI per il servizio web
I connettori personalizzati supportano OpenAPI 3.0. Puoi anche creare manualmente la specifica. Per informazioni sulle specifiche OpenAPI, consulta Specifiche OpenAPI.
Puoi anche generare automaticamente la specifica OpenAPI 2.0 utilizzando il middleware gin swagger. Per informazioni, vedi Gin Swagger. Devi convertire la specifica OpenAPI 2.0 in specifica OpenAPI v3.0 utilizzando Swagger Converter.
Specifica OpenAPI di esempio.
{"openapi":"3.0.0",
"info":{"title":"Go HTTPbin Proxy Service",
"description":"A simple Go service that proxies requests to httpbin.org, adding custom headers.",
"version":"1.0.0"},
"servers":[{"url":"http://localhost:8080"}],
"paths":{"/getData":{"get":{"summary":"Fetch data from httpbin.org/get",
"description":"Sends a GET request to httpbin.org/get, including any custom headers.",
"responses":{"200":{"description":"Successful response from httpbin.org",
"content":{"application/json":{"schema":{"type":"object"}}}}}}},
"/postData/{id}":{"post":{"summary":"Post data to httpbin.org/post",
"description":"Sends a POST request to httpbin.org/post with data, including any custom headers.",
"parameters":[{"in":"path",
"name":"id",
"required":true,
"schema":{"type":"string"}}],
"requestBody":{"content":{"application/json":{"schema":{"type":"object",
"properties":{"name":{"type":"string"},
"address":{"type":"string"},
"gender":{"type":"string"}},
"required":["name",
"address",
"gender"]}}}},
"responses":{"200":{"description":"Successful response from httpbin.org",
"content":{"application/json":{"schema":{"type":"object"}}}},
"400":{"description":"Bad Request - Invalid request body"}}}}}}
Crea un connettore personalizzato e convalida il servizio
Devi creare un connettore personalizzato e poi convalidare il servizio web utilizzandolo in una connessione in Application Integration.
Prima di iniziare
Configura Private Service Connect (PSC) per questa macchina virtuale, quindi crea un collegamento endpoint.
Crea un connettore personalizzato
Nella console, vai alla pagina
Connettori di integrazione > Connettori personalizzati,
quindi seleziona o crea un progetto Google Cloud .
Fai clic su Crea nuovo per aprire la pagina Crea connettore personalizzato.
Nella sezione Dettagli connettore, specifica i campi obbligatori, ad esempio Nome connettore e Nome visualizzato.Inoltre, inserisci i casi d'uso per il connettore nel campo Descrizione.
Configura la destinazione del connettore per l'accesso al backend: attiva questa opzione. Vengono visualizzate le sezioni di configurazione aggiuntive nella pagina.
Service account: seleziona un account di servizio con i ruoli richiesti.
Logo: carica un'immagine in un bucket Cloud Storage per utilizzarla come logo del connettore.
Nella sezione Connector Specification (Specifica del connettore), inserisci l'URL pubblico della specifica Open API o carica il file di specifica in un bucket Cloud Storage.
Nella sezione Destinazione connettore, aggiungi l'indirizzo IP dell'allegato dell'endpoint e la porta su cui è in esecuzione il servizio.
Nella sezione Autenticazione connettore, seleziona Nessuna autenticazione. I tipi di autenticazione non sono supportati per i connettori Marketplace.
Nella sezione Variabili di backend, aggiungi le variabili che vuoi utilizzare come input durante la creazione della connessione. Queste variabili vengono visualizzate nella pagina di creazione della connessione e vengono inviate a ogni chiamata API effettuata al servizio. I valori che non cambieranno con le API, come le credenziali di backend di terze parti, devono essere aggiunti in questa sezione.
Crea il connettore personalizzato. Assicurati di aver specificato un logo e descritto i casi d'uso per il connettore personalizzato.
Crea una connessione
Dopo aver creato il connettore personalizzato, crea la connessione per questo connettore.
Nella console Google Cloud, vai alla pagina Integration Connectors > Connessioni
e poi seleziona o crea un progetto Google Cloud.

You can also manually create the specification. For information about the OpenAPI specifications, see [OpenAPI specifications](https://swagger.io/specification/).\n\nYou can also autogenerate the OpenAPI 2.0 specification using gin swagger middleware. For information, see [Gin Swagger](https://github.com/swaggo/gin-swagger). You must convert the OpenAPI 2.0 specification to OpenAPI v3.0 specification by using [Swagger Converter](https://converter.swagger.io/).\nSample OpenAPI specification. \n\n```bash\n{\n \"openapi\": \"3.0.0\",\n \"info\": {\n \"title\": \"Go HTTPbin Proxy Service\",\n \"description\": \"A simple Go service that proxies requests to httpbin.org, adding custom headers.\",\n \"version\": \"1.0.0\"\n },\n \"servers\": [\n {\n \"url\": \"http://localhost:8080\"\n }\n ],\n \"paths\": {\n \"/getData\": {\n \"get\": {\n \"summary\": \"Fetch data from httpbin.org/get\",\n \"description\": \"Sends a GET request to httpbin.org/get, including any custom headers.\",\n \"responses\": {\n \"200\": {\n \"description\": \"Successful response from httpbin.org\",\n \"content\": {\n \"application/json\": {\n \"schema\": {\n \"type\": \"object\"\n }\n }\n }\n }\n }\n }\n },\n \"/postData/{id}\": {\n \"post\": {\n \"summary\": \"Post data to httpbin.org/post\",\n \"description\": \"Sends a POST request to httpbin.org/post with data, including any custom headers.\",\n \"parameters\": [\n {\n \"in\": \"path\",\n \"name\": \"id\",\n \"required\": true,\n \"schema\": {\n \"type\": \"string\"\n }\n }\n ],\n \"requestBody\": {\n \"content\": {\n \"application/json\": {\n \"schema\": {\n \"type\": \"object\",\n \"properties\": {\n \"name\": {\n \"type\": \"string\" \n\n },\n \"address\": {\n \"type\": \"string\"\n },\n \"gender\": {\n \"type\": \"string\" \n }\n },\n \"required\": [\n \"name\",\n \"address\",\n \"gender\"\n ]\n }\n }\n }\n },\n \"responses\": {\n \"200\": {\n \"description\": \"Successful response from httpbin.org\",\n \"content\": {\n \"application/json\": {\n \"schema\": {\n \"type\": \"object\"\n }\n }\n }\n },\n \"400\": {\n \"description\": \"Bad Request - Invalid request body\"\n }\n }\n }\n }\n }\n}\n```\n\nCreate a custom connector and validate the service\n--------------------------------------------------\n\nYou must create a custom connector and then validate the web service by using it in a connection in Application Integration.\n\n### Before you begin\n\nSet up [Private Service Connect](https://cloud.google.com/integration-connectors/docs/network-connectivity-private) (PSC) for this virtual machine and then create an endpoint attachment.\n\n### Create a custom connector\n\n1. In the [Console](https://console.cloud.google.com/), go to the **Integration Connectors \\\u003e Custom connectors** page, and then select or create a Google Cloud project.\n\n\n [Go to the Custom connectors page](https://console.cloud.google.com/connectors/custom-connectors)\n2. Click **Create new** to open the **Create custom connector** page.\n3. In the **Connector details** section, specify the required fields, such as **Connector name** and **Display name** .Also, enter the use cases for the connector in the **Description** field.\n4. **Configure connector destination for backend access**: Enable this option. This shows the additional configuration sections in the page.\n5. **Service account**: Select a service account that has the required roles.\n6. **Logo** : Upload an image to a Cloud Storage bucket to use it as the connector logo. **Note:** Ensure your Cloud Storage bucket has the [public access prevention](/storage/docs/using-public-access-prevention#console) disabled.\n7. In the **Connector Specification** section, either enter the public URL of your Open API specification or upload your specification file to a Cloud Storage bucket.\n8. In **Connector Destination** section, add the IP address of the endpoint attachment and the port on which service is running.\n9. In **Connector Authentication** section, select **No Authentication**. Authentication types are not supported for Marketplace connectors.\n10. In **Backend Variables** section, add the variables you want to take as input while creating the connection. These variables appear in the connection creation page and are sent on every API call made to the service. The values which will not change with APIs, such as third-party backend credentials must be added in this section.\n11. Create the custom connector. Ensure that you have specified a logo and described the use cases for the custom connector.\n\n### Create a connection\n\nAfter you create the custom connector, create the connection for this connector.\n\n1. In the [Cloud console](https://console.cloud.google.com), go to the **Integration Connectors \\\u003e Connections** page and then select or create a Google Cloud project.\n\n\n [Go to the Connections page](https://console.cloud.google.com/connectors/connections)\n2. Click **Create new** to open the **Create connection** page.\n3. Select the custom connector that you created.\n4. Add values for the connection fields that you had defined.\n5. Create the connection.\n\n### Validate the service\n\nTo validate the service, create a new integration.\n\n1. In the Google Cloud console, go to the **Application Integration** page and then create an integration.\n2. Add API trigger and the connector task.\n3. Configure the connector task to use the connection created in the earlier step. Add Data Mapper if required.\n4. Set up the connectorInputPayload for the connector as per the schema.\n5. Run the integration to verify that the connection is working.\n\nIf the Integration runs successfully and returns expected response, the web service is validated.\n\nWhat's next\n-----------\n\n- Learn how to [create a startup script for the web service](/integration-connectors/docs/marketplace/create-startup-script)."]]
