创建 Lambda 函数，该函数将使用 SES 接收规则解析上传到 S3 的电子邮件

Question

我想创建 Lambda 函数来解析通过 SES 接收规则上传到 S3 存储桶的电子邮件。

通过 SES 接收规则上传到 S3 存储桶工作正常。所以，它已经经过测试并确认它可以正确上传文件。

我的 Amazon Lambda 函数：

var AWS = require('aws-sdk');
var s3 = new AWS.S3();

var bucketName = 'bucket_name/folder/destination';

exports.handler = function(event, context, callback) {
console.log('Process email');

var sesNotification = event.Records[0].ses;
console.log("SES Notification:\n", JSON.stringify(sesNotification, null, 2));

// Retrieve the email from your bucket
s3.getObject({
        Bucket: bucketName,
        Key: sesNotification.mail.messageId
    }, function(err, data) {
        if (err) {
            console.log(err, err.stack);
            callback(err);
        } else {
            console.log("Raw email:\n" + data.Body);

            // Custom email processing goes here

            callback(null, null);
        }
    });
};

上传文件时会触发 lambda，但我收到 [SignatureDoesNotMatch] 错误：

{ "errorMessage": "The request signature we calculated does not match the signature you provided. Check your key and signing method.", "errorType": "SignatureDoesNotMatch", "stackTrace": [ "Request.extractError (/var/runtime/node_modules/aws-sdk/lib/services/s3.js:524:35)", "Request.callListeners (/var/runtime/node_modules/aws-sdk/lib/sequential_executor.js:105:20)", "Request.emit (/var/runtime/node_modules/aws-sdk/lib/sequential_executor.js:77:10)", "Request.emit (/var/runtime/node_modules/aws-sdk/lib/request.js:615:14)", "Request.transition (/var/runtime/node_modules/aws-sdk/lib/request.js:22:10)", "AcceptorStateMachine.runTo (/var/runtime/node_modules/aws-sdk/lib/state_machine.js:14:12)", "/var/runtime/node_modules/aws-sdk/lib/state_machine.js:26:10", "Request. (/var/runtime/node_modules/aws-sdk/lib/request.js:38:9)", "Request. (/var/runtime/node_modules/aws-sdk/lib/request.js:617:12)", "Request.callListeners (/var/runtime/node_modules/aws-sdk/lib/sequential_executor.js:115:18)" ] }

如果有人能帮我解决这个问题，那就太好了！谢谢

好的，我解决了。 bucketName 应仅包含存储桶的名称。但是密钥可以包含到您文件的确切路径的其余部分 "directory".

所以，基本上 bucketName 不应该包含子文件夹，但 key 应该。

谢谢
