The rail transit vehicle benchmarking intelligent detection system ...

APPLICATION-BASED DATA INTERACTION METHOD AND APPARATUS

Provided are an application-based data interaction method and apparatus. The method comprises: sending a data interaction request; choosing to create a first channel performing data interaction with a third party; establishing, by means of the third party and an application server, a second channel for data interaction; selectively opening the first channel and the second channel; and when both the first channel and the second channel are open, performing data interaction with the application server, so that when it is impossible to directly perform data interaction with the application server, data interaction with the application server can be indirectly performed by opening the first channel and the second channel, thereby improving the degree of usage satisfaction of data interaction of the application.
