Abstract
With the rapid developing of mobile networking, social applications, the major users of which are college students, have already occupied an indispensable position on the internet. At present, however, most of such social applications for campus are only implemented with the function of virtual social intercourse. Seldom model has been designed and implemented for real name registration and O2O serices. Besides, it is difficult to get in time response from others when various problems appeared or helps needed . Hence, the application provides a O2O service platform, which can response immediately.
Therefore, the application was designed by using the technology of Node.js + Express + MongoDB + Json to establish the Server, data transmission and data interaction. The function of instant response was implemented by using NotificationManager in Android SDK. A better performance is realized by using these technology, and better user experience is provided at the same time.
