|
|
39 | # two URLs are required |
|
|
40 | # 1. $XML_URL http://test.webwork.maa.org/mod_xmlrpc |
|
|
41 | # points to the Webservice.pm and Webservice/RenderProblem modules |
|
|
42 | # Is used by the client to send the original XML request to the webservice |
|
|
43 | # |
|
|
44 | # 2. $FORM_ACTION_URL http:http://test.webwork.maa.org/webwork2/html2xml |
|
|
45 | # points to the renderViaXMLRPC.pm module. |
|
|
46 | # |
|
|
47 | # This url is placed as form action url when the rendered HTML from the original |
|
|
48 | # request is returned to the client from Webservice/RenderProblem. The client |
|
|
49 | # reorganizes the XML it receives into an HTML page (with a WeBWorK form) and |
|
|
50 | # pipes it through a local browser. |
|
|
51 | # |
|
|
52 | # The browser uses this url to resubmit the problem (with answers) via the standard |
|
|
53 | # HTML webform used by WeBWorK to the renderViaXMLRPC.pm handler. |
|
|
54 | # |
|
|
55 | # This renderViaXMLRPC.pm handler acts as an intermediary between the browser |
|
|
56 | # and the webservice. It interprets the HTML form sent by the browser, |
|
|
57 | # rewrites the form data in XML format, submits it to the WebworkWebservice.pm |
|
|
58 | # which processes it and sends the the resulting HTML back to renderViaXMLRPC.pm |
|
|
59 | # which in turn passes it back to the browser. |
|
|
60 | # 3. The second time a problem is submitted renderViaXMLRPC.pm receives the WeBWorK form |
|
|
61 | # submitted directly by the browser. |
|
|
62 | # The renderViaXMLRPC.pm translates the WeBWorK form, has it processes by the webservice |
|
|
63 | # and returns the result to the browser. |
|
|
64 | # The The client renderProblem.pl script is no longer involved. |
|
|
65 | # 4. Summary: renderProblem.pl is only involved in the first round trip |
|
|
66 | # of the submitted problem. After that the communication is between the browser and |
|
|
67 | # renderViaXMLRPC using HTML forms and between renderViaXMLRPC and the WebworkWebservice.pm |
|
|
68 | # module using XML_RPC. |
