Calling a WebService through HTTP GET ? (HELP!)

[Benne Smith]

Hi,

I have a simple webservice, with one function on the following local path :

http://localhost/testws/tester.asmx

I would like to call it, using HTTP GET (or some form of simple, url with
all the parameters in), like this;

http://localhost/testws/tester.asmx/myfunction?param1=hello&param2=world

But it does not work ? It comes with the following error;

Thanks,

Benne

Re: Calling a WebService through HTTP GET ? (HELP!)

There is a subtle difference between .NET Framework 1.0 and 1.1 regarding
the 'protocols' that are permitted to communicate with a WebService.

By default, you can use SOAP, GET or POST method to communicate with a
WebService running on 1.0. But in version 1.1, only SOAP is enabled by
default.

You have to add the following settings to you Web.config file to re-enable
GET/POST methods.

Example:

<configuratio n>
<system.web>
<webServices>
<protocols>
<add name="HttpGet" />
<add name="HttpPost" />
</protocols>
</webServices>
