(Mono C#) Making SOAP Requests using the REST APIThere's no reason a SOAP request cannot be sent using the REST API. It's only a matter of adding a SOAP specific header, and providing the SOAP XML request body. The response body is the SOAP response XML. This example sends a request to ws.cdyne.com to get city weather by zip code.
// Demonstrates how to do a SOAP request using the REST API. // This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. // -------------------------------------------------------------------------------- // Also see Chilkat's Online WSDL Code Generator // to generate code and SOAP Request and Response XML for each operation in a WSDL. // -------------------------------------------------------------------------------- Chilkat.Rest rest = new Chilkat.Rest(); // This is the request to be sent: // POST /WeatherWS/Weather.asmx HTTP/1.1 // Host: wsf.cdyne.com // Content-Type: text/xml; charset=utf-8 // Content-Length: length // SOAPAction: "http://ws.cdyne.com/WeatherWS/GetCityWeatherByZIP" // // <?xml version="1.0" encoding="utf-8"?> // <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> // <soap:Body> // <GetCityWeatherByZIP xmlns="http://ws.cdyne.com/WeatherWS/"> // <ZIP>string</ZIP> // </GetCityWeatherByZIP> // </soap:Body> // </soap:Envelope> // Note: The application does not need to set the Host or Content-Length headers. // Chilkat will automatically add these headers. // Make the initial connection (without sending a request yet). bool bTls = false; int port = 80; bool bAutoReconnect = true; // In this particular case, it is important to connect to "wsf.cdyne.com", not "ws.cdyne.com"... bool success = rest.Connect("wsf.cdyne.com",port,bTls,bAutoReconnect); if (success != true) { Debug.WriteLine(rest.LastErrorText); return; } // Add request headers: success = rest.AddHeader("Content-Type","text/xml; charset=utf-8"); success = rest.AddHeader("SOAPAction","http://ws.cdyne.com/WeatherWS/GetCityWeatherByZIP"); // Build the SOAP XML request body.
