How to use the functions in the aws-sdk-js-v3?
问题
我正在尝试使用@aws-sdk/lib-dynamodb文档中提供的一个函数。它被称为unmarshallOutput。
我如何在我的代码中使用这个函数？
import { DynamoDBClient, ScanCommand } from "@aws-sdk/client-dynamodb";
const client = new DynamoDBClient({ region: "us-east-1" });
export async function handler(event, context, callback) {
const params = {
TableName: "Amenities"
};
try {
const command = new ScanCommand(params);
const data = await client.send(command);
return data.Items;
} catch (err) {
return {
statusCode: 500,
body: JSON.stringify({
message: "从DynamoDB检索数据时出错"
})
};
}
}

有两个ScanCommands，一个在client-dynamodb中，另一个在lib-dynamodb中。你需要从lib-dynamodb中导入ScanCommand，而不是从client-dynamodb中。
英文:
There are two ScanCommands, one in client-dynamodb and one in lib-dynamodb. You need to import the ScanCommand from lib-dynamodb, not client-dynamodb.
