为了满足以下要求，我需要解决我面临的一个问题：
要求：1.通过POST方法将HTML表单中的表单数据提交到lambda函数的API网关。电子邮件地址中的参数之一。2.将参数从POST请求传递到lambda函数。Lambda函数应通过SES向收件人发送电子邮件
问题：我可以通过POST调用来执行lambda函数，但无法传递变量。
测试用例：为了测试功能，我已经对收件人地址进行了硬编码，以便在lambda函数被点击时会收到一封电子邮件。我正在尝试传递“名称”参数，并让电子邮件的正文响应-嗨，“名称”。目前，我得到的答复是-Hi hi undefined。
下面是我正在使用的代码

var aws = require('aws-sdk');
var ses = new aws.SES({ region: 'us-west-2' });
exports.handler = (event, context, callback) => {
const emailbody = JSON.parse(event.body)
var params = {
Destination: {
ToAddresses:
},
Message: {
Body: {
Text: {
Data: "Hi" + JSON.stringify(emailbody.name)
}
},
Subject: {
Data: "Test Email from lambda"
}
},
Source: "[email protected]"
};
ses.sendEmail(params, function (err, data) {
callback(null, { err: err, data: data });
if (err) {
console.log(err);
context.fail(err);
} else {
console.log(data);
context.succeed(event);参考：https : //aws.amazon.com/premiumsupport/knowledge-center/lambda-send-email-ses/
我也尝试直接通过event.name传递变量，但没有成功插入变量。

};我对开发和API世界非常陌生。任何帮助，将不胜感激 ：）

您所拥有的是一个查询字符串。查询是字符串，是您将值传递为的位置key=value&key2=value2
从API网关进行测试时，应在称为的部分下添加查询字符串，Query Strings而不是Request Body
在您的情况下，查询字符串为：
name=Tera&email=aditya.prakash%40psyora.com
您应该在lambda内部以如下方式访问它event. queryStringParameters.name：
您event.body包含的值name=Tera&email=aditya.prakash%40psyora.com表示您的表单已过帐x-www-form-urlencoded。那就是从html表单提交表单的类型，因此，在您的情况下，您需要对lambda中的编码字符串进行解码。
const qs = require('querystring')
exports.handler = (event, context, callback) => {
const parsedQueryString = qs.parse(event.body)
const name = parsedQueryString.name
}
希望这可以帮助。
