wsResponse (Type of variable)

In french: wsRéponse

The wsResponse type is used to get:

the XML source code of the Webservice response.
the value of the different parts of the Webservice response (for the Webservices returning several responses).

The characteristics of this type can be defined and modified by several WLanguage properties.

Note: See Declaring a variable for more details.

Example

For a Webservice that returns 2 responses (and not a structured response)

wsResp is wsResponse = WSProcedure()
Trace(wsResp["part1"].subElement1)
Trace(wsResp["part2"].subElement2)

For a Webservice for which we want to retrieve the entire response XML (and the XML sent)

// WSDL of Webservice:
// http://www.webservicex.net/globalweather.asmx?WSDL

// Variable of parameter type of the Webservice function
paramGetWeather is GlobalWeather.GetWeather
paramGetWeather.CityName = "Paris-Charles De Gaulle Airport"
paramGetWeather.CountryName = "France"

// Variable of return type of the Webservice function
resGetWeatherResponse is GetWeatherResponse
// Instead of:
// resGetWeatherResponse = GetWeather(paramGetWeather)
// Use a "wsResponse" variable to get the entire XML result and
// a "wsRequest" variable to retrieve everything that was sent to the Webservice function
wsResp is wsResponse
wsReq is wsRequest
// Ability to force the HTTP time-out of the request: example HTTPTimeOut(10*1000)
wsResp = GlobalWeather.GetWeather(wsReq,paramGetWeather)
IF ErrorOccurred THEN
// Ability to get the entire XML returned with: wsResp.SourceXML
Error(ErrorInfo(), ...
"---------------------------------- Details of the XML request sent: ", wsReq.SourceXML, ...
"---------------------------------- Details of the XML response received: ", wsResp.SourceXML)

ELSE
// Then, assign the return type of the Webservice function to the variable
resGetWeatherResponse=wsResp.Value
// If the result is not the expected one,
// you have the ability to get the entire result XML with wsResp.SourceXML
//trace(resGetWeatherResponse.GetWeatherResult..Value)

xmlWeather is xmlDocument=XMLOpen(resGetWeatherResponse.GetWeatherResult..Value, ...
fromString)
IF ErrorOccurred THEN
Error(ErrorInfo())
ELSE
IF xmlWeather.CurrentWeather.Status..Text~="Success" THEN
Info("City: " + xmlWeather.CurrentWeather.Location, ...
"Time: " + xmlWeather.CurrentWeather.Time, ...
"Wind: " + xmlWeather.CurrentWeather.Wind, ...
"Visibility: " + xmlWeather.CurrentWeather.Visibility, ...
"Temperature: " + xmlWeather.CurrentWeather.Temperature, ...
"Dew point: " + xmlWeather.CurrentWeather.DewPoint, ...
"Humidity: " + xmlWeather.CurrentWeather.RelativeHumidity, ...
"Pressure: " + xmlWeather.CurrentWeather.Pressure)
ELSE
Error(resGetWeatherResponse.GetWeatherResult, ...
"---------------------------------- Details of the XML response received:", wsResp.SourceXML)
END
END
END

Remarks

Properties specific to the description of wsResponse variables

The following properties can be used to handle a wsResponse variable:

Property name	Type used	Effect

ResponsePart	Array	Used to get the XML code corresponding to the specified response. You also have the ability to use the following notation: Name_wsResponse_Variable["Response_name"] This property is available in read-only.
XMLSource	Binary/Buffer	XML source received from the server. This property is available in read-only.
Value	Character string	Returns the XML code corresponding to the first part of the response. This property is available in read-only.

Caution: If the Webservice ne returns a single response, we recommend that you keep the following syntax:

res is ReturnType = WSProcedure()

Note: These properties can be used with one of the following syntaxes:

<Variable name>..<Property name>
<Variable name>.<Property name>

Operating mode

The wsResponse type is used to get the XML source of the request sent for the consumption of the Webservice.

SOAPPrepare already gives the information for the general case but not when the Webservice requires:

specific data in its header (SOAPAddHeader),
an assertion (SOAPAddSAMLAssertion) in case of Sesam Vitale for example.

Practically, the standard call to a function:

WebserviceResponse = WebserviceFunction(Param1, Param2)

can be replaced by:

MyRequest is wsRequest
WebserviceResponse = WebserviceFunction(MyRequest, Param1, Param2)

The entire XML source of request can be included in a buffer via the following code:

MyRequest..XMLSource

This feature may be useful during the design step and it is required to get some certifications.
