下面是python的示例代码，

from boto3 import client as boto3_client
from datetime import datetime
import json

lambda_client = boto3_client('lambda')

def lambda_handler(event, context):
    msg = {"key":"new_invocation", "at": datetime.now()}
    invoke_response = lambda_client.invoke(FunctionName="another_lambda_",
                                           InvocationType='Event',
                                           Payload=json.dumps(msg))
    print(invoke_response)

顺便说一句，您还需要向您的lambda角色添加这样的策略

   {
        "Sid": "Stmt1234567890",
        "Effect": "Allow",
        "Action": [
            "lambda:InvokeFunction"
        ],
        "Resource": "*"
    }

你可能会使用Async.js的瀑布特性——参见本文档第3步大代码块底部的示例:

因为这个问题，亚马逊发布了Step Functions (https://aws.amazon.com/step-functions/)。

AWS Lambda背后的核心原则之一是，您可以更多地关注业务逻辑，而不是将它们联系在一起的应用程序逻辑。步骤函数允许您编排函数之间的复杂交互，而无需编写代码。

以下是如何在javascript/typescript中做到这一点，而无需安装完整的aws-sdk包。

import { InvokeCommand, LambdaClient, LogType } from "@aws-sdk/client-lambda";

const client = new LambdaClient({
    region: "US-EAST-1"
});

const payload = JSON.stringify({
  data: "your input"
})

const command = new InvokeCommand({
  FunctionName: "your function name",
  Payload: payload,
  LogType: LogType.Tail,
});

const { Payload } = await client.send(command);
const response: any = Payload;
const result = Buffer.from(response).toString();

return result;

一个AWS Lambda函数可以调用另一个吗 简单的c#代码——

InvokeRequest RebookingLambdalambda = new InvokeRequest
{
  FunctionName = "Name"
  InvocationType = InvocationType.RequestResponse,
  Payload = "Json Data"
};

下面是python的示例代码，

from boto3 import client as boto3_client
from datetime import datetime
import json

lambda_client = boto3_client('lambda')

def lambda_handler(event, context):
    msg = {"key":"new_invocation", "at": datetime.now()}
    invoke_response = lambda_client.invoke(FunctionName="another_lambda_",
                                           InvocationType='Event',
                                           Payload=json.dumps(msg))
    print(invoke_response)

顺便说一句，您还需要向您的lambda角色添加这样的策略

   {
        "Sid": "Stmt1234567890",
        "Effect": "Allow",
        "Action": [

        ],
        "Resource": "*"
    }
