Triggers class

container: Container

属性值

创建触发器。

Azure Cosmos DB 支持在创建、更新和删除时执行的 JavaScript 中定义的预先和发布触发器。

有关更多详细信息，请参阅服务器端 JavaScript API 文档。

示例

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);

function create(body: TriggerDefinition, options?: RequestOptions): Promise<TriggerResponse>

参数

返回

查询所有触发器。

function query(query: SqlQuerySpec, options?: FeedOptions): QueryIterator<any>

参数

返回

查询所有触发器。

示例

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();

function query<T>(query: SqlQuerySpec, options?: FeedOptions): QueryIterator<T>

参数

返回

读取所有触发器。

示例

读取数组的所有触发器。

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();

function readAll(options?: FeedOptions): QueryIterator<TriggerDefinition & Resource>

参数

返回
