Get Game Score

When the "Send" button is clicked, the webpage will perform basic validation,

then use the given details to call the API, with service name "getGameScore".

If there are no errors with the information provided, the webpage will proceed to

parse a JSON string from "getGameScore" into "responseObj"

We will be able to import useful data from these 3 sources, and to call a function and store the user ID and PIN.

Put the value of getUserID() into the value of userID.
Put the value of getPIN() into the value of PIN.

getUserID&getPIN

This code required data variable from Jsp, please refer to getUserID&getPIN above.

The serviceName is getGameScore.

And the userID and PIN are equal to the values which the user entered.

Once the "Send" button is clicked, it will set service header values.

And it will get and validate from these values.

If the GameID is equal to to nothing, the error will be displayed: Game ID cannot be blank.

If the startDate is equal to to nothing, the error will be displayed: Start Date cannot be blank.

If the endDate is equal to to nothing, the error will be displayed: End Date cannot be blank.
