how to debug drogon web in vscode? Or, can you share other debugging methods

[an-tao]

You could run your web application in vscode debugging mode, set breakpoints and run it step by step as debugging any other c++ program. To make an HTTP request, you can use a browser or command-line tool (such as curl). And you could also set LogLevel to "Trace" to get more Drogon debug logs.

I'm using Visual Studio Code to debug my Drogon application on Linux.

Not sure what you're having trouble with, but here's how my application is set up:

• GCC flags for Drogon and all dependencies: -c -fvisibility=hidden -Wpedantic -Wall -Wextra -Wno-unknown-pragmas -shared-libgcc -fpic -funsafe-math-optimizations -std=c++17 -fvisibility-inlines-hidden -g3 -ggdb -fpie (the -g3 -ggdb are important to generate debug information in GDB format, using -Og actually made debugging worse)

• My Visual Studio Code project uses the following .vs/launch.json file:

{
  // Use IntelliSense to learn about possible attributes.
  // Hover to view descriptions of existing attributes.
  // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
  "version": "0.2.0",
  "configurations": [
    {
      "name": "(gdb) Launch",
      "type": "cppdbg",
      "request": "launch",
      "program": "${workspaceFolder}/bin/linux-gcc9.3-amd64-debug/NuclexAlexandriaNative",
      "args": [],
      "stopAtEntry": false,
      "cwd": "${workspaceFolder}",
      "environment": [],
      "externalConsole": false,
      "MIMode": "gdb",
      "setupCommands": [
        {
          "description": "Enable pretty-printing for gdb",
          "text": "-enable-pretty-printing",
          "ignoreFailures": true
        }
      ]
    }
  ]
}

And of course, GDB, the GNU Debugger, must be installed.

mac with apple silicon chip(m1) have not suport to GDB... I Think it work lldb
