Hi
Is there a recommended or a built in way to implement a REST interface in IIB9 ? The intent is to expose conventional URI's such as
GET /classes
GET /students
GET /class/:id
GET /student/:id
PUT /class/new
and so on.. for the class and student entity.
The responses are easy to create with a mapping node (and a db:select) or a MQ exchange with the host system. I am wondering about how to process the requests ( parse URL's , calling appropriate mapping nodes or MQ sub flows ) .. |

Hi
I have been able to figure out how to use the QueryString and how to specify a model for the HTTP POST (in case it contains an XML).
I need advice on how to model the REST resource conventions. For example, i need to support a dynamic URL such as the following
| Code: |
/find_account/:type/:key.xml
|
Sample URI's
| Code: |
/find_account/RET/100011.xml
/find_account/CRP/100022.xml
|
As you can see, there is no QueryString, & I need to parse the RequestURI to get the value of :type & :key variables and then use them in by Mapping Node/ESQL.
Is there a way to model these in IIB9 (or the upcoming IIB10?) ? Or should I just go ahead and parse the URI?

Have you looked at the trace node output for
${Root}
and
${LocalEnvironment}
for your test messages? some of what you want may already be there.

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions. |

Hi
Yes , the RequestURI contains the path which can be tokenised by splitting on the '/' separator.. but this code can quickly get complicated if I need to handle nested resources and id's ... I was looking for some pattern / available convention / code to do this .. Have started wiring it up myself for the moment, will share the code on github shortly , in case anyone needs it..
