Convert a long number to a string when serialized to JSON

Since all the digits in JavaScript are 64-bit floating-point numbers, integers can only accurately represent 53bit long numbers.

In JSON data obtained from the server, there is an ID that is a long integer type, and the link generated by the client based on this ID is inaccurate.

Method 1 is that the ID in the backend ViewModel is changed to string type, but this method will require a lot of conversion in the background, not very convenient.

Method 2: When the MVC action is JSON output, the long type property is output directly to a string.
