1. 使用Lambda函数的内存来提高GetObject请求的性能。

示例代码：

exports.handler = async (event) => { const AWS = require('aws-sdk'); const s3 = new AWS.S3(); const params = { Bucket: "my-bucket", Key: "my-key" };

const response = await s3.getObject(params).promise(); //使用async/await模式来优化GetObject请求性能
console.log(response);

const responseBody = JSON.stringify(response.Body);
const responseCode = 200;

const responseObj = {
    statusCode: responseCode,
    body: responseBody
};

return responseObj;

};

2. 使用S3 Transfer Acceleration（S3传输加速）来提高Lambda函数中GetObject请求的性能。

示例代码：

exports.handler = async (event) => { const AWS = require('aws-sdk'); const s3 = new AWS.S3({useAccelerateEndpoint: true}); //使用S3传输加速 const params = { Bucket: "my-bucket", Key: "my-key" };

const response = await s3.getObject(params).promise(); //使用async/await模式来优化GetObject请求性能
console.log(response);

const responseBody = JSON.stringify(response.Body);
const responseCode = 200;

const responseObj = {
    statusCode: responseCode,
    body: responseBody
};

return responseObj;

};

以上两种方法可以帮助您在Lambda函数中提高GetObject请求的性能。
