the signal and slot mechanism is the core mechanism of QT . Signals and slots are an advanced interface that is applied to communication between objects, which is the core feature of Qt and is also an important part of QT's differentiation from other toolkits. Signals and slots are a communication mechanism defined by QT itself, independent of the standard C/s + + language, so proper processing of signals and slots requires the use of a QT tool called the MOC (Meta Object Compiler) , which is a

The most recent project in the front and back is completely decoupled, with grunt management of the project. This can lead to a problem: cross-domain issues occur when the front-end interface is not on a server because it is being called at development time. However, it is not possible to implement a true cross-domain in either JSONP or Cros, as the project is actually published under the same server.At this time our grunt-connect-proxy on the stage,
