// Unknown indicates got some error which is not defined
var Unknown = DefineCode(5000001, "error", "Unknown", fmt.Sprintf(`
Unknown error code. Usually you will see this code in three cases:
1. You forget to define Code or function DefineCode not being executed;
2. This is not Beego's error but you call FromError();
3. Beego got unexpected error and don't know how to handle it, and then return Unknown error

A common practice to DefineCode looks like:
%s

In this way, you may forget to import this package, and got Unknown error. 

Sometimes, you believe you got Beego error, but actually you don't, and then you call FromError(err)
