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
