ABP vNext V5 + VS2022+ .Net 6.0 学习笔记（3）--如何调试

实际上的Abp应用,大部分是前后端分离的. 对于自己开发的MVC的程序,大多数在controller里打断点, 单步调试就能找到问题了.

但ABP的程序,比如对数据库的查询都是用仓储类IRepository,

例如GetListAsync出错了

引用的dll出了错,没法单步调试

 public async Task<List<TodoItemDto>> GetListAsync()
        {
            var items = await _todoItemRepository.GetListAsync();
            //entity=> Dto
            return items.Select(item => new TodoItemDto
            {
                Id = item.Id,
                Text = item.Text
            }).ToList();
        }

应对方法:  浏览器F12开发者工具,看一下错误信息, 好像没帮助

 

直接访问 url 的Get方法, 错误信息隐藏起来了.

 

 查看服务端的log,  路径在HttpApi.Host\Logs

对应的log内容就很清晰了
