Lab #6 - Web services access using SOAP

CS 183 - Hypermedia and the Web

For this final lab assignment for the class you will be using a SOAP API in PHP to access an Internet accessible SOAP service. The service that you will contact is a simple one, a temperature service. The service

Your task is to write a PHP script that will receive input from this html page containing a simple form, and use the input data to contact the service for temperature information via the SOAP API. The script should then return an HTML page containing the result from the service in some clearly readable format.

To perform this lab assignment, you will need to do the following:

• Copy the following:
  /afs/cats.ucsc.edu/users/r/akames/courselocker/nusoap.php
  
  to your working web directory for this assignment.
• At the top of your php script you need to include the following statement:

  include_once('nusoap.php');

• Here is an example of a php script that uses the NuSoap API to contact Amazon, retrieving XML results similar to those used in labs #1 and #5.
• You should note that this example uses an array to handle multiple parameters to the request method (the name of this method you will need to change), and the response returns a large multidimensional array. For the assignment you only need to deal with a single parameter in the request and a single value in the response. As a result, do not use the $parameters array that was shown in class, and in the textbook's Amazon example (and in the example above). Instead, pass the zipcode directly as the single parameter for $soap_proxy->getTemp. The temperature will be returned as the return value of $soap_proxy->getTemp(), as in:
  
  $temp = $soap_proxy->getTemp($zipcode);
  
  
• The URL to the WSDL is: http://www.xmethods.net/sd/2001/TemperatureService.wsdl
• Here you may find SOAP Request and Response samples, in XML.

For submission please email Sasha [at] cse [dot] ucsc [dot] edu your PHP script and a URL to the script on a working webserver such as your user directory on the people.ucsc.edu servers.

NOTE: Please copy your php script file to a .txt file before you attach, so it is not filtered out by the email filters running on the campus network.
