原标题：Serverless 应用开发指南： Node.js 编程返回动态 HTML
在我们进行 Serverless + SPA 应用开发之前，先看看官方的相应 DEMO。
serverless install -u https://github.com/serverless/examples/tree/master/aws-node-serve-dynamic-html-via-http-endpoint -n node-serve-html
然后执行部署
serverless deploy
serverless.yml 文件，如下：
# Serving HTML through API Gateway for AWS Lambdaservice: node-serve-htmlframeworkVersion: ">=1.1.0 <2.0.0"provider: name: aws runtime: nodejs4.3functions: landingPage: handler: handler.landingPage events: - http: method: get path: landing-page
对应的，我们的 handler.js 文件：
'use strict';module.exports.landingPage = (event, context, callback) => { let dynamicHtml = '<p>Hey Unknown!</p>'; // check for GET params and use if available if (event.queryStringParameters && event.queryStringParameters.name) {
dynamicHtml = `<p>Hey ${event.queryStringParameters.name}!</p>`;
} const html = `
<html> <style>
h1 { color: #73757d; }
</style>
<body>
<h1>Landing Page</h1>
${dynamicHtml} </body>
</html>`; const response = { statusCode: 200, headers: { 'Content-Type': 'text/html',
}, body: html,
}; // callback is sending HTML back
callback(null, response);
};上面的代码所做的就是，当我们对 landing-page 发出请求的时候，便执行上面的 landingPage 代码。然后返回对应的 HTML body、statusCode、headers。
相应的部署日志如下：

然后我们访问：https://uocym5fe3m.execute-api.us-east-1.amazonaws.com/dev/landing-page，就会返回对应的 HTML，即：
Landing Page Hey phodal!
