您可以通过电子邮件发送Amazon Lambda错误日志吗

Question

是否可以通过电子邮件发送与Cloudwatch中出现的Lambda函数相同的错误日志？

Answer 1

要交付日志，您可以创建cloudwatch订阅过滤器，可以单击日志组，然后在AWS lambda上单击流并选择lambda函数。

日志将以gzip格式提供，您可以使用以下代码将其解压缩

var AWS = require('aws-sdk');
var zlib = require('zlib');
// Set the region 
AWS.config.update({region: 'REGION'});

// Create sendTemplatedEmail params 
var params = {
  Destination: { /* required */
    CcAddresses: [
      'EMAIL_ADDRESS',
      /* more CC email addresses */
    ],
    ToAddresses: [
      'EMAIL_ADDRESS',
      /* more To email addresses */
    ]
  },
  Source: 'EMAIL_ADDRESS', /* required */
  Template: 'TEMPLATE_NAME', /* required */
  TemplateData: '{ \"REPLACEMENT_TAG_NAME\":\"REPLACEMENT_VALUE\" }', /* required */
  ReplyToAddresses: [
      'EMAIL_ADDRESS',
  ],
};

exports.handler = function(input, context) {
    var payload = new Buffer(input.awslogs.data, 'base64');
    zlib.gunzip(payload, function(e, result) {
        if (e) { 
            context.fail(e);
        } else {
            result = JSON.parse(result.toString('ascii'));
            console.log("Event Data:", JSON.stringify(result, null, 2));
           var sendPromise = new AWS.SES({apiVersion: '2010-12- 
           01'}).sendTemplatedEmail(params).promise();

          // Handle promise's fulfilled/rejected states
           sendPromise.then(
             function(data) {
               console.log(data);
             }).catch(
                 function(err) {
                   console.error(err, err.stack);
             });  
           context.succeed();
        }
    });
};

此代码基本上是获取日志，将其解压缩并使用AWS SES通过电子邮件发送 要获取更多信息，请点击sdk。
