Node.js Nodejs 从另一个 lambda 函数中调用 AWS.Lambda 函数

使用aws-sdk从另一个Lambda函数中调用Lambda函数非常简单，每个Lambda中都有aws-sdk.

I suggest starting with something simple first.
This is the "Hello World" of intra-lambda invocation:

Lambda_A invokes 兰巴达 with a Payload containing a single parameter name:'Alex'.
兰巴达 responds with Payload: "Hello Alex".

First create 兰巴达 which expects a name property on the event parameter
and responds to request with "Hello "+event.name:

兰巴达

exports.handler = function(event, context) {
  console.log('Lambda B Received event:', JSON.stringify(event, null, 2));
  context.succeed('Hello ' + event.name);
};

Ensure that you give 兰巴达 and Lambda_A the same role.
E.g: create a role called lambdaexecute which has AWSLambdaRole, AWSLambdaExecute and AWSLambdaBasicExecutionRole (All are required):

Lambda_A

var AWS = require('aws-sdk');
AWS.config.region = 'eu-west-1';
var lambda = new AWS.Lambda();

exports.handler = function(event, context) {
  var params = {
    FunctionName: '兰巴达', // the lambda function we are going to invoke
    InvocationType: 'RequestResponse',
    LogType: 'Tail',
    Payload: '{ "name" : "Alex" }'
  };

  lambda.invoke(params, function(err, data) {
    if (err) {
      context.fail(err);
    } else {
      context.succeed('兰巴达 said '+ data.Payload);
    }
  })
};

保存这两个Lambda函数后，测试运行Lambda_A:

一旦basic个内部Lambda调用开始工作，就可以轻松地扩展它，以调用更复杂的Lambda函数.

你要做的最重要的事情是remember到102.
