Question

我正在尝试设置一个api网关，只需通过lambda发送和发送电子邮件，而且是ses。

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


exports.handler = function(event, context) {
    var output = querystring.parse(event);
    console.log("Incoming: ", output["email"]);
    email=output["email"]

    console.log("Incoming: ", email);
    var eParams = {
        Destination: {
            ToAddresses: [email]
        },
        Message: {
            Body: {
                Text: {
                    Data: "some trial text"
                }
            },
            Subject: {
                Data: "Email Subject!!!"
            }
        },
        Source: "info@ayyy.com"
    };

    console.log('===SENDING EMAIL===');
    var email = ses.sendEmail(eParams, function(err, data){
        if(err) console.log(err);
        else {
            console.log("===EMAIL SENT===");
            console.log(data);


            console.log("EMAIL CODE END");
            console.log('EMAIL: ', email);
            context.succeed(event);

        }
    });

};

Lambda代码看起来像这样。如何从api传递事件数据？

控制台日志如下所示：

Answer 1

Log the event and see how it is structured. Your function fails from the start as the email is undefined. In API Gateway, if you defined LAMBDA PROXY INTEGRATION, your event body will be structured like this:

{
  "message": "Good day, John of Seattle. Happy Friday!",
  "input": {
    "resource": "/{proxy+}",
    "path": "/Seattle",
    "httpMethod": "POST",
    "headers": {
      "day": "Friday"
    },
    "queryStringParameters": {
      "time": "morning"
    },
    "pathParameters": {
      "proxy": "Seattle"
    },
    "stageVariables": null,
    "requestContext": {
      "path": "/{proxy+}",
      "accountId": "123456789012",
      "resourceId": "nl9h80",
      "stage": "test-invoke-stage",
      "requestId": "test-invoke-request",
       ... 
      },
      "resourcePath": "/{proxy+}",
      "httpMethod": "POST",
      "apiId": "r275xc9bmd"
    },
    "body": "{ \"callerName\": \"John\" }",
    "isBase64Encoded": false
  }
}

You want to read the queryStringParameters Object.

确定。我解决了这个问题。需要用JSON.parse解析JSOn然后它工作。

为什么我不能将api params传递给lambda函数？
