使用WCF的简单REST服务

Question

I'm trying to make a simple REST service in VS2010 (.NET 4) with one method that receives three string parameters. I want it to be accessed using both GET and POST (because 3'rd param could be quite big sometimes)

In class MyREST.cs I have this code

    [WebGet(UriTemplate = "s={s}&sp={sp}&p={p}")]
    public string Process(string s, string sp, string p)
    {
        // some processing
        return result;
    }

Same for POST

When I try to access the service with an url like

http://localhost:57129/OneTestREST/s=str1&sp=str2&p=str3

I get error

Exception Details: System.Web.HttpException: A potentially dangerous Request.Path value was detected from the client (&).

If I change the attribute to

[WebGet(UriTemplate = "/{s}/{sp}/{p}")]

It works ok. But I would like to access it with first syntax

Any idea why is this happening?

Thank you

Answer 1

[WebGet]
public string Process(string s, string sp, string p)
{
    // some processing
    return result;
}

then

http://localhost:57129/OneTestREST/?s=str1&sp=str2&p=str3
