Service Interceptor Guide

Hi All,

Good day.

Is there any one have a clear ideas about how to set up the plugin configurations?

it is not hard to write .net code, it is not hard to test the .net code.

But finally when I put the custom plugins into the REST, it is very hard to figure out where when and what is happening.

from user point view, things are clear, like 1, if someone already had a mobile in the system, stop insert same mobile number, 2, or stop same email address entry.

The REST API document is missing the detail how client calls REST.

also there is something not in the document. what is RegEx? like this:

2014-12-09 16:30:44.3753|Debug|Verb and Placement matched but RegEx for URI match '^CRM/Constituents/[^/]*/Snapshot(/)?$' didn't match the actual URI 'ReferenceData/SystemDefaults/Summary'.

I can see the REST structure is very complicated.

is there some documents about this part of REST?

have fun

HI All,

Good day.

is there anyone can tell me why same codes worked with "POST" method (insert) didn't work with "PUT" method(update)?

is there something different inside REST between "POST" URI and "PUT" URI?

Thank you very much for your help.

have fun

Ben

Hi All,

Good day.

those are the code for my plugin.

LTR_ACCEPTABLE_DUP_EMAILS is a custom table keeping duplicated emails exceptions.

The plugin worked on POST method, but it never worked on PUT method.

Am I missing something?

have fun

Ben

Hi All,

Good day.

Patrick Drew from Sydney Theatre Company told me the trick.

if plugin uses PUT method, the config  should have a * included.

if plugin uses POST method, the config should not have a * included.

Here is an example from Patrick.

Normal 0 false false false EN-AU ZH-CN X-NONE MicrosoftInternetExplorer4

Thank you Patrcik.

Have fun.

Ben

Hi Ben,

We've lodged a TASK ticket for a very similar issue.  I don't think it's appearing in the Tessitura known defects list yet, but will be there soon as reference #71283.

The issue is that plugins fired from the General Tab are unable to return Validation Exception messages to the application and instead throw the errors you are seeing.  There is no fix at this point.

Cheers
