Question

我需要创建一个通过Amazon SES发送html电子邮件的api。我已正确创建了ses凭证，并且想在javascript（nodejs）中创建一个AWS lambda。由于缺乏良好的AWS文档来使用javascript发送电子邮件，我需要知道如何创建一个lambda来发送电子邮件并以适当的消息响应到AWS api网关。

以下是用javascript编写的代码。在AWS Lambda上运行完美，并且在从AWS Api网关调用时运行良好（没有格式错误的消息错误）：

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);
});
};
