Node.js 在NodeJS服务器上，当验证作业运行时（需要半个小时），在这段时间内，整个应用程序停止工作
我正在使用MEAN stack开发我的应用程序。我的服务器有三个客户端app 1。iOS应用程序2。Android应用程序和3。基于浏览器的应用程序。所有应用程序均由单一服务器提供。当我运行一些长时间的数据处理工作时，我面临着这个问题。这项工作需要半小时才能完成一项处理。由于Nodejs的单线程模式，当这个作业开始运行时，在这半个小时内，三个应用程序都停止工作，因为服务器没有及时响应。以下是我的工作代码Node.js 在NodeJS服务器上，当验证作业运行时（需要半个小时），在这段时间内，整个应用程序停止工作,node.js,Node.js,我正在使用MEAN stack开发我的应用程序。我的服务器有三个客户端app 1。iOS应用程序2。Android应用程序和3。基于浏览器的应用程序。所有应用程序均由单一服务器提供。当我运行一些长时间的数据处理工作时，我面临着这个问题。这项工作需要半小时才能完成一项处理。由于Nodejs的单线程模式，当这个作业开始运行时，在这半个小时内，三个应用程序都停止工作，因为服务器没有及时响应。以下是我的工作代码 1.

1。调用此处理的API
//API来验证所有可能的组合
app.get（'/api/validateworkout/：clubid'，SecurityService.isRestAPIRequestSecure，workoutValidateService.validateGeneratedWorkouts）；
2.以下是validateGeneratedWorkouts函数的代码
