And when the character strings are all correct, judging the accessed extended function module to be a legal module. And when any relevant field is incorrect, judging that the accessed extended function module is an illegal module.
In the embodiment of the invention, when the extended function module is determined to be an illegal module, the error information is uploaded.
Specifically, when the extended function module is determined to be an illegal module, the error information is uploaded, and the access to the illegal extended function module is prompted. Further specifically, when the content of a certain relevant field is judged to be incorrect, the judgment of other fields is interrupted, and the uploaded and accessed extended function module is an illegal module. Or when the content of a certain relevant field is judged to be incorrect, other fields are continuously judged, the incorrect field is uploaded, and the access to the illegal extended function module is prompted.
