Pass method parameters through the URL

Question

How do I capture the parameters requested by the URL in a webservice?

For example: I have the following webservice: http://localhost/teste/WebService1.asmx/Produto

How to pass method parameters Produto? So they’d look something like this:

http://localhost/teste/WebService1.asmx/Produto?a=sincroniza&dado=produto&id_vendedor=2666&id_grupo=1700&id_usuario=2925&id_empresa=2004

And how would I read it?

Answer 1

First of all, these parameters are called query string.

You can declare in your method for it to accept requests HTTP GET

[WebMethod]
[ScriptMethod(UseHttpGet=true)]
public string ConverterNumero(int param){ 
    ... 
}

And change in the archive web config.

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

After that, you can call your webservice thus

http://site.com/Servico.asmx/ConverterNumero?param=1

And your method ConverterNumero will be called with the value of param being 1.
