使用VS Code(C#)调试dotnet core 2.0 AWS Lambda函数 [英] Debug dotnet core 2.0 AWS Lambda Functions in VS Code (C#)

问题描述

我正在使用VS Code通过dotnet core 2.0 CLI编写Lambda函数.

I'm using VS Code to write Lambda functions using the dotnet core 2.0 CLI.

• VS代码v1.24.1
• dotnet Core CLI v2.1.200

问题
我无法使用在VS Code中编写的功能来使调试器在本地使用.

Problem
I can't get the debugger to work locally with the function I've written in VS Code.

我在var body = request?.Body;行上放置了一个断点(请参见下面的Function.cs代码块).然后，当我在VS Code的 Debug 选项卡中单击start debugging按钮时，我得到以下信息:

I place a breakpoint on the line var body = request?.Body; (See Function.cs code block below). When I then click the start debugging button in the Debug tab in VS Code, I get the following:

-------------------------------------------------------------------
You may only use the Microsoft .NET Core Debugger (vsdbg) with
Visual Studio Code, Visual Studio or Visual Studio for Mac software
to help you develop and test your applications.
-------------------------------------------------------------------
Loaded 'C:\Program Files\dotnet\shared\Microsoft.NETCore.App\2.0.7\System.Private.CoreLib.dll'. Skipped loading symbols. Module is optimized and the debugger option 'Just My Code' is enabled.

The program '[49584] ClientManagement.TestAsyncFunction.Tests.dll' has exited with code 0 (0x0).

Function.cs

Lambda函数使用API​​GatewayEvents包来接受来自API网关的请求

The Lambda Function uses the APIGatewayEvents package to accept a request from the API Gateway

public async Task<APIGatewayProxyResponse> FunctionHandler(APIGatewayProxyRequest request, ILambdaContext context)
{
    var body = request?.Body;

    // do something asynchronously

    return new APIGatewayProxyResponse()
    {
        Body = JsonConvert.SerializeObject(body),
        StatusCode = 200,
        Headers = new Dictionary<string, string>{ {"Content-Type", "application/json"} }
    };
}

launch.json

我已将其配置为使用Function.cs dll(由vs代码创建的文件正在测试项目中)

I've configured this to use the Function.cs dll's (The file that was created by vs code was hitting the test project)

"version": "0.2.0",
"configurations": [
    {
        "name": ".NET Core Launch (lambda)",
        "type": "coreclr",
        "request": "launch",
        "preLaunchTask": "build",
        "program": "${workspaceFolder}/src/ClientManagement.TestAsyncFunction/bin/Debug/netcoreapp2.0/ClientManagement.TestAsyncFunction.dll",
        "args": [],
        "cwd": "${workspaceFolder}/src/ClientManagement.TestAsyncFunction",
        "console": "internalConsole",
        "stopAtEntry": false,
        "internalConsoleOptions": "openOnSessionStart"
    },
    {
        "name": ".NET Core Attach",
        "type": "coreclr",
        "request": "attach",
        "processId": "${command:pickProcess}"
    }
}

我在这里看过这篇文章:

I've seen this post here:
https://cloudncode.blog/2017/01/24/getting-started-with-writing-and-debugging-aws-lambda-function-with-visual-studio-code/

但是我认为这种方法不适用于dotnet core 2.0.我也做了很多谷歌搜索，几乎没有发现有关如何在VS Code中调试dotnet core 2.0功能的信息.

But I don't think this method will work for dotnet core 2.0. I've also done a lot of googling and have found almost no information on how to debug dotnet core 2.0 functions in VS Code.

推荐答案

好，所以我发现了这一点，这表明目前尚不可能:

OK so I found this, which says it's not possible at the moment:

https://github.com/aws/aws-lambda-dotnet/issues/246

现在转移到NodeJs和Serverless软件包以进行此操作:

Am moving to NodeJs and the Serverless package to do this for now:

https://www.npmjs.com/package/serverless

如果/当dotnet核心发生变化时，将更新此内容

Will update this if / when things change for dotnet core
