This is a refined and focused question that I asked last week about a project I am working on to use the web service http://www.upcdatabase.com via xml-rpc .net. I am working in c#. The request requires a named method (“lookup”) as well as 2 named parameters (“rpc_key”) and (“upc”), both types are stings. My initial thought was to create an interface like this:
[XmlRpcUrl("http://www.upcdatabase.com/xmlrpc")]
public interface UPChelp : IXmlRpcProxy
[XmlRpcMethod("lookup")]
upcLookupValues lookupUPC(string rpc_key, string upc);
upcLookupValues is a struct that is returned defined as:
public struct upcLookupValues
{
public string upc;
public int pendingUpdates;
public string status;
public string ean;
public string issureCountryCode;
public bool found;
public string description;
public string message;
public string size;
public string issureCountry;
public string noCacheAfterUTC;
public string lastModifiedUTC;
}
The proxy generation I have been working with is
UPChelp upcObj = XmlRpcProxyGen.Create<UPChelp>();
upcLookupValues myLookup = upcObj.lookupUPC("000000000000000000000000000000000000000000”, "639382000393");
I get a response of invalid parameters.. So while reading the xml-rpc faq I came across:
“2.20 How do I call an XML-RPC method with a variable number of parameters? The params keyword can be used to call an XML-RPC method which take a variable number of parameters. For example, if an XML-RPC method takes a variable number number of integer parameters it could be defined like this: [XmlRpcUrl("http://www.cookcomputing.com/notimpl.rem")] public interface IParams : IXmlRpcProxy { [XmlRpcMethod]
int UseNumbers(params int[] numbers); } And called like this: IFoo proxy = (IFoo)XmlRpcProxyGen.Create(typeof(IFoo)); proxy.SendMultipleParameters(1); proxy.SendMultipleParameters(1, 2, 3);”Alternatively the parameters in this example can be supplied as an array of type int[]: in开发者_运维百科t[] parameters = new int[] { 1, 2, 3 }; proxy.SendMultipleParameters(parameters);"
My problem is I don’t understand how to apply this concept to my project, (I am a newbie), I tried upcLookupValues[] parameters = new string[] { "rpc_key", "upc" }; But I get a cant implicitly convert string[] to readUPC.upcLookupvalues[]. I also don’t understand how to define the new proxy for submission. My fingers are crossed this post makes sense. I am sure you C# xml-rpc folks are laughing right now.
