Triggers class

Paket:
@azure/cosmos

Operasi untuk membuat, meningkatkan, mengkueri, dan membaca semua pemicu.

Gunakan container.triggers untuk membaca, mengganti, atau menghapus Pemicu.

Properti

container

Metode

create(TriggerDefinition, RequestOptions)

Buat pemicu.

Azure Cosmos DB mendukung pemicu pra dan pasca yang ditentukan dalam JavaScript untuk dijalankan pada pembuatan, pembaruan, dan penghapusan.

Untuk detail tambahan, lihat dokumentasi JAVAScript API sisi server.

Contoh

import { CosmosClient, TriggerDefinition, TriggerType, TriggerOperation } from "@azure/cosmos";

const endpoint = "https://your-account.documents.azure.com";
const key = "<database account masterkey>";
const client = new CosmosClient({ endpoint, key });
const { database } = await client.databases.createIfNotExists({ id: "Test Database" });
const { container } = await database.containers.createIfNotExists({ id: "Test Container" });

const triggerDefinition: TriggerDefinition = {
  id: "sample trigger",
  body: "serverScript() { var x = 10; }",
  triggerType: TriggerType.Pre,
  triggerOperation: TriggerOperation.All,
};

const { resource: trigger } = await container.scripts.triggers.create(triggerDefinition);
query(SqlQuerySpec, FeedOptions)

Mengkueri semua Pemicu.
query<T>(SqlQuerySpec, FeedOptions)

Mengkueri semua Pemicu.

Contoh

import { CosmosClient } from "@azure/cosmos";

const endpoint = "https://your-account.documents.azure.com";
const key = "<database account masterkey>";
const client = new CosmosClient({ endpoint, key });
const { database } = await client.databases.createIfNotExists({ id: "Test Database" });
const { container } = await database.containers.createIfNotExists({ id: "Test Container" });

const querySpec = {
  query: "SELECT * FROM root r WHERE r.id=@id",
  parameters: [
    {
      name: "@id",
      value: "<trigger-id>",
    },
  ],
};
const { resources: results } = await container.scripts.triggers.query(querySpec).fetchAll();
readAll(FeedOptions)

Membaca semua Pemicu.

Contoh

Membaca semua pemicu ke array.

import { CosmosClient } from "@azure/cosmos";

const endpoint = "https://your-account.documents.azure.com";
const key = "<database account masterkey>";
const client = new CosmosClient({ endpoint, key });

const { database } = await client.databases.createIfNotExists({ id: "Test Database" });

const { container } = await database.containers.createIfNotExists({ id: "Test Container" });

const { resources: triggerList } = await container.scripts.triggers.readAll().fetchAll();
