Question

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

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运行。

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中的 Debug 标签中单击start debugging按钮时，将得到以下信息：

-------------------------------------------------------------------
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APIGatewayEvents包来接受来自API网关的请求

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（vs代码创建的文件正在测试项目中）

"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：
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，发现几乎没有关于如何在VS Code中调试dotnet core 2.0功能的信息。

Answer 1

好，所以我发现了这一点，这表明目前尚不可能：

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：

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

如果/当点网核心发生变化时，将对此进行更新

Answer 2

processId，应将其设置为1，因为Docker将入口点可执行PID分配为1。它位于VS Code的launch.json中。
