If by that you mean sending the attributes of a unique parameter in the
body, yet you can but you have to tell it to expose first :

@[ws]expose(ReturnType, body=InputDataType)
def yourfunction(self, inputdata):
pass

This is a recent addition and it has not been properly documented yet
(it is, but on the FunctionArgument which is not a public api, and with
a different name).


Cheers,

Christophe

I had a look at your code, you only have to replace __body__ with body.

The '__body__' name is used when calling a rest function, to pass the request body as a GET parameter.

Ok, now I tested it. See the updated version at the same thing but now I get server side:

}

Also I looked a bit at the code and it seems that the pecan.py is missing a thing like: 

args_from_body(funcdef, request.body, request.content_type)

Can this be something that can make trouble?

Endre.

Hi,

Sorry we did not update the group thread, but the problem was solved in the repository.

If you still have the issue, please give us details: the framework you use, some code samples or any thing that will help to understand what is going on.

Have someone tried to solve this problem? Server is returning the same error (list index out of range) when im trying to pass a json body (also post request). Does not work with xml body as well. Is there any fix or solution?

Im using WSME 0.5b1 and Pecan framework. I want to make HTTP POST call e.g. http://127.0.0.1/test so i have defined method for that call with @wsexpose(Test, body=Test):

@wsexpose(Test, body=Test)

def post(self, input):

     test = Test()

     test.name = input.name

     test.id = input.id

     return test

and Test class is:

class Test():

     name = text

     id = int

JSON which im passing in request:

{ "name"="testName",

  "id" = 1}

With standarad pecan expose (@expose) it is working correctly, but @wsexpose gives me "list index out of range". Cant find solution for that.

I have solved my problem. The point is that the newest version of WSME installed by easy_install is 0.5b1 and this version does not contain changes from February, when bug was submitted.
