Line 登入，出現 "由於無法取得官方帳號的資訊，因此無法新增好友。" 錯誤訊息。

Line 登入時，若是指定了 bot_prompt=aggressive ，但沒有在 Login Channel 指定相對應的 Official Account ，就會看到 "由於無法取得官方帳號的資訊，因此無法新增好友。" 的錯誤訊息，如下圖:

此時要去 Line Login Channel 的 Add friend option 中，指定 Linked LINE Official Account，如下圖:

可參考: https://developers.line.biz/en/docs/line-login/link-a-bot/#link-a-line-official-account

多專案的 swagger 設定 (swashbuckle.aspnetcore)

多專案(multiple projects)時，會產生多個 xml document, 叫用 IncludeXmlComments 時記得要把每個專案的 xml document 都載入，才能顯示不同專案中的註解和說明 (comment)。

範例如下:

builder.Services.AddSwaggerGen(options =>

{

    options.SwaggerDoc("v1", new OpenApiInfo { Title = "My API", Version = "v1" });



    //多個 Project, 每一個 xmldocument 都要載入

    List<string> xmlFiles = Directory.GetFiles(AppContext.BaseDirectory, "*.xml", SearchOption.TopDirectoryOnly).ToList();

    foreach (string fileName in xmlFiles)

    {

        string xmlFilePath = Path.Combine(AppContext.BaseDirectory, fileName);

        if (File.Exists(xmlFilePath))

            options.IncludeXmlComments(xmlFilePath, includeControllerXmlComments: true);

    }



    //防止 SchemaId 的錯誤

    options.CustomSchemaIds(type => type.ToString());

});
