Multiple methods with different parameters WCF REST -


i've been given task implement following using wcf rest:

 resource       post                          put                  delete /device        create new device   list devices  bulk update devices  delete devices

this isn't problem per-se, problem these functions need different parameters. example, post method takes wsdevice, while method takes wscollectionquery parameter (used querying .. collections). 4 methods take different parameters, have accessible through /device uri.

this should possible in rest (according http://pages.apigee.com/web-api-design-ebook-thank-you-download.html?aliid=1911411 , got table in first place. see page 7).

what have:

[operationcontract, webinvoke(method = "post",     responseformat = webmessageformat.json,     bodystyle = webmessagebodystyle.wrapped,     uritemplate = "/v" + rest_api_version + "/device/?device={device}")] wsresult devicepost(string sessionkey, wsdevice device);  [operationcontract, webinvoke(method = "get",     responseformat = webmessageformat.json,     bodystyle = webmessagebodystyle.wrapped,     uritemplate = "/v" + rest_api_version + "/device/?collectionquery={collectionquery}")] wsresult deviceget(string sessionkey, wscollectionquery collectionquery);  [operationcontract, webinvoke(method = "put",     responseformat = webmessageformat.json,     bodystyle = webmessagebodystyle.wrapped,     uritemplate = "/v" + rest_api_version + "/device/?devices={devices}")] wsresult deviceput(string sessionkey, wsdevice[] devices);  [operationcontract, webinvoke(method = "delete",     responseformat = webmessageformat.json,     bodystyle = webmessagebodystyle.wrapped,     uritemplate = "/v" + rest_api_version + "/device/")] wsresult devicedelete(string sessionkey);

so i'd have same uritemplate, different outcome depending on passed parameters in message body. know added parameters above in uri, attempt differentiate between uri.

the error i'm getting following: 

uritemplatetable not support multiple templates have equivalent path template '/v1/device/?device={device}' have different query strings, query strings cannot disambiguated via literal values. see documentation uritemplatetable more detail.

i know why i'm receiving error. i'd know how else solve problem? i've looked @ having 1 function taking method = "*" works, can't access parameters other 1 passed in function.

if knows solution or can it's not possible if isn't, it'd much, appreciated!

edit: know can't pass complex types in get, that's issue can worked around.

probably best solution in case use same uritemplate 4 methods:

uritemplate = "/v" + rest_api_version + "/device/?device={device}&collectionquery={collectionquery}&devices={devices}"

then can check necessary parameter in each case.

quite why doesn't throw ambiguous exception beats me however.
