从AWS Lambda函数发送电子邮件

Question

我已经创建了一个基本的lambda函数，该函数应该从SES服务发送电子邮件，但是不起作用。

我已经遵循了本教程：here。我已经创建了正确的IAM策略并将其附加到功能上，但是我认为这不是问题。

我已经为函数创建了一个测试配置，并且控制流未到达sendEmail的内部，而且我不确定为什么。

const aws = require('aws-sdk')
const ses = new aws.SES({ region: 'us-east-1' });

exports.handler = async (event, context, callback) => {
  const printOut = JSON.stringify(event);
  console.log(`Received event: ${printOut}`);

  const params = {
    Destination: {
      ToAddresses: ["[email protected]"]
    },
    Message: {
      Body: {
        Text: {
          Data: event['desc']
        }
      },
      Subject: {
        Data: "Email from xxxxxxx Contact Us Form"
      }
    },
    Source: "[email protected]"
  };

  console.log(`sending: ${JSON.stringify(params)}`);

  ses.sendEmail(params, function (err, data) {
    callback(null, { err: err, data: data });
    if (err) {
      console.error(err);
      context.fail(err);
    } else {
      console.log(data);
      context.succeed(event);
    }

    console.log(`Done!`);
  });
};

这是我当前的输出：

Response:
null

Request ID:
"xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxxxx"

Function Logs:
START RequestId: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxxxx Version: $LATEST

如您所见，从不调用sendEmail函数内部的控制台中断/错误。不太确定为什么。

我确实确保验证正在测试的两个电子邮件地址，但没有骰子。

您必须使其非异步或将承诺返回给调用方（您可以将该承诺直接返回给运行时）。像这样：

const aws = require('aws-sdk')
const ses = new aws.SES({region: 'us-east-1'});

exports.handler = async (event, context, callback) => {
    const printOut = JSON.stringify(event);
    console.log(`Received event: ${printOut}`);

    const params = {
        Destination: {
            ToAddresses: ["[email protected]"]
        },
        Message: {
            Body: {
                Text: {
                    Data: event['desc']
                }
            },
            Subject: {
                Data: "Email from xxxxxxx Contact Us Form"
            }
        },
        Source: "[email protected]"
    };

    console.log(`sending: ${JSON.stringify(params)}`);

    return ses.sendEmail(params, null).promise();
};
