我正在使用的业务应用程序angularJS.我的一个服务方法返回我byte[](包括PDF文件内容)现在我需要下载此文件作为PDF客户端机器使用JavaScript.

如何使用HTML5 Apis或任何JavaScript API？

我用过 window.atob(base64String)

我正在使用Web Api和Angular JS开发单页应用程序.我想抓住一个伟大的水疗应用程序的所有最佳实践.

我想知道这是将Web Api项目作为单独项目托管的最佳实践,或者只是与您的spa一起包含在同一个项目中.

谢谢

我正在使用WebApi和AngularJS开发应用程序.我花了一些时间申请后得到这个例外.我在这个应用程序中使用EntityFramework.

我的MVC应用程序面临一个奇怪的问题,一切正常,我不知道现在这个应用程序发生了什么.我只是更新所有的nuget包.得到以下错误

我想在我的MVC项目中添加SignalR.我需要从类库中调用SignalR客户端方法.我做了以下代码

public class CommomHubManager : ICommomHubManager
    {
        readonly IHubContext Context;
        public CommomHubManager()
        {
            Context = Helpers.Providers.HubContextProvider<Hubs.Notifications>.HubContext;
        }
        public Task AddUserToGroup(string groupName)
        {
            return Task.Factory.StartNew(() => {
                Context.Clients.All.addUserToGroup(groupName);
            });
        }
    }

它不起作用,但是当我尝试从WebApi调用另一个Hub类方法时,它的工作正常.我想知道可以从普通的C#类调用SignalR Client方法吗？
