WWSAPI to WCF interop 1: WSHttpBinding with no security

  • 發行項

WCF provides a number of standard bindings, each targeting a specific usage scenario. WSHttpBinding is for the mainline Internet web services scenario. It uses the newer SOAP version 1.2 and WS-Addressing version 1.0 and enables a wide range of security settings over the public http/https transport. WWSAPI does not have an equivalence of the WSHttpBinding (or any of the WCF standard bindings), but since its default SOAP version, WS-Addressing version and encoding format match those in WSHttpBinding, interoperating between WWSAPI and WSHttpBinding is straightforward. For example, to use service proxy to talk to a WSHttpBinding endpoint without security, you only need to write the code like following snippet (variable declaration and heap/error creation omitted). Notice that no channel properties or security description is specified at WsCreateServiceProxy.

// Create the proxy

hr = WsCreateServiceProxy(

WS_CHANNEL_TYPE_REQUEST,

WS_HTTP_CHANNEL_BINDING,

NULL, // security description

NULL, // proxy properties

0, // proxy property count

NULL, // channel properties

0, // channel property count

&proxy,

error);

if (FAILED(hr))

{

goto Exit;

}

hr = WsOpenServiceProxy(

proxy,

&address,

NULL,

error);

if (FAILED(hr))

{

goto Exit;

}

// make the call through the proxy

hr = WSHttpBinding_ICalculator_Add(

proxy,

1,

2,

&result,

heap,

NULL,

0,

NULL,

error);

if (FAILED(hr))

{

goto Exit;

}
