Background documentationChecking Input Values Locate this document in the navigation structure

 

By providing Web services you can publish and make externally available functions that until now have only been used internally.

If a user is able to make entries into their functions then to avoid unwanted results they must ensure that their input options are restricted to those values that they have predefined.

Multiple options are available to do this.

  • Check if input values exist and if they have a valid length.

  • Check if the input values have the predefined data type.

  • If there is an input interval, check if it is adhered to.

  • Predefine the permitted input value (white list filter).

  • If this is not possible, predefine which input values are not allowed (black list filter).
