我有一个问题.在我的网络应用程序中,我有一个页面,启动另一个线程,耗时的任务.在这个新线程中,我调用了一个我的架构方法(在另一个项目中 - 一个架构项目).问题是:在其中一种方法中,我访问了一个HttpContext.Current.Session字段.但是当我启动应用程序时,会抛出一个异常,说该对象(HttpContext.Current.Session)有一个空引用.我怎么能设置新线程的上下文与HttpApplication上下文相同才能访问HttpContext.Current.Session？
我分别通过npm install -g cordova和npm install -g phonegap安装了cordova e phonegap .然后我通过cordova创建了一个HelloWorld应用程序,创建了HelloWorld mynamespace.helloworld HelloWorld.它工作正常!然后我将我的工作目录更改为HelloWorld,我尝试通过cordova平台添加android -d为Android构建应用程序,但它无法正常工作.这是输出:
