如何在 AWS Lambda 节点 js 中发送 html 电子邮件，为 AWS API 网关返回格式正确的响应

Question

我需要创建一个通过 Amazon SES 发送 html 电子邮件的 API。 我正确地创建了我的 ses 凭证，我想在 javascript (nodejs( 中创建 AWS lambda。由于缺乏使用 javascript 发送电子邮件的良好 AWS 文档，我需要知道如何创建一个 lambda，用于发送电子邮件并使用适当的消息响应 AWS api 网关。

以下是用javascript编写的代码。在 AWS lambda 中完美运行，从 AWS API 网关调用时效果很好(没有格式不正确的消息错误(：

var aws = require("aws-sdk");
var ses = new aws.SES({
accessKeyId: "Your SES Access Key",
secretAccesskey: "Your Secret key",
region: "us-east-1" // CHANGE with the region where you configured SES
});
exports.handler = function(event, context, callback) {
var requestPath = JSON.parse(JSON.stringify(event.pathParameters));
var requestBody = JSON.parse(event.body);
var responseBody = {};
var response = {};
if (
requestBody &&
requestBody.emailFrom &&
requestBody.subject &&
requestBody.htmlBody
) {
var emailTo = requestPath.emailto;
var emailFrom = requestBody.emailFrom;
var subject = requestBody.subject;
var htmlBody = requestBody.htmlBody;
} else {
responseBody = {
result: "fail",
resultCode: 400,
description:
"Incorrect Parameters. Mandatory: emailFrom, subject and bodyHTML"
};
response = {
statusCode: 400,
headers: {
"Access-Control-Allow-Origin": "*"
},
body: JSON.stringify(responseBody),
isBase64Encoded: false
};
callback(null, response);
}
var emailParams = {
Destination: {
ToAddresses: [emailTo]
},
Message: {
Body: {
Html: {
Data: htmlBody
}
},
Subject: {
Data: subject
}
},
Source: emailFrom
};

var email = ses.sendEmail(emailParams, function(err, data) {
var resultCode = 200;
if (err) {
var responseBody = {
result: "FAIL",
resultCode: 500,
description: "Error sending email: " + err
};
resultCode = 500;
} else {
var responseBody = {
result: "OK",
resultCode: 200,
description: "Email sent successfully"
};
}

response = {
statusCode: resultCode,
headers: {
"Access-Control-Allow-Origin": "*"
},
body: JSON.stringify(responseBody),
isBase64Encoded: false
};
callback(null, response);
});
};
