Description
Technical Field
The invention belongs to the technical field of mobile communication, and particularly relates to a method for starting an external application program by a browser through an intermediate device.
Background
When a user displays a local application program in user equipment through a web browser, an external application program cannot be directly operated in a browser web page, because the browser does not have an interface for starting the application program; on the other hand, even if the external application program required by the user is installed locally on the user equipment, when the user needs to run the local external application program while browsing the website, the user cannot acquire the complete path of the application program. The external application is directed to the browser program, and other applications which interact with the browser besides the browser program can be referred to as external applications of the browser.
The reason why the browser cannot start the external application program is mainly two-way: on one hand, the browser and the webpage can not start the external application program because the browser has no complete path of the external application program; another aspect is because the browser does not have an API interface to launch the application. Due to security policies in a general browser, although an < input file = type > tag can select a certain file in a local computer and read data therein, a final webpage cannot read a complete path where the file is located through an interface provided by the browser, and cannot run the read data as an application program.
