Stored procedures
Builds the HTTP request to call a function of a Webservice. This request can be modified to adapt it to the expectations of the Webservice, if necessary. It can then be sent using HTTPSend.
// Standard call that is using the full call to a WebService method
stParam1 is Param1
stParam1.String = "a string"
stParam1.Int = 2
stRet is MyResult
stRet = MyFunction(stParam1)
// Retrieve the Buffer for the call using SoapRunXML
stParam1 is Param1
stParam1.String = "a string"
stParam1.Int = 2
cMyRequest is httpRequest = SOAPToHTTP(MyFunction, stParam1)
WSRequest is wsRequest
AnHTTPRequest is httpRequest
AnHTTPResponse is httpResponse
BaseWS.Address = ...
AnHTTPRequest = SOAPToHTTP(BaseWS._Return__2_Param_type_string,
WSRequest, "MyString1", "MyString2"
IF NOT ErrorOccurred() THEN
AnHTTPResponse is HTTPSend(AnHTTPRequest)
IF NOT ErrorOccurred() THEN
Info("HTTPSend(AnHTTPRequest) = '" + AnHTTPResponse.Content + "'")
Error("HTTPSend(AnHTTPRequest).'" + ErrorInfo() + "'")
Error("SOAPToHTTP().'" + ErrorInfo() + "'")
<Result> = SOAPToHTTP(<Function> [, <HTTP request to use>] [, <Parameter 1> [... [, <Parameter N>]]])
<Result>: httpRequest variable
httpRequest variable corresponding to the generated HTTP request.
<Function>: Character string
Name of the function for which the SOAP request must be built. This function is a WDSL function of the Webservice previously imported into the project.
<HTTP request to use>: Optional wsRequest variable
Name of the variable of type wsRequest that corresponds to an HTTP request with the additional information to be used.
<Parameter 1>: Optional variant
First parameter expected by the function.
<Parameter N>: Optional variant
Nth parameter expected by the function.
Webservices have a very wide spectrum and not all of them comply with the standard. The ease of use of a third-party Webservice in an application or site depends on its designer. This function makes it possible to retrieve the content of the HTTP request that is sent to the third-party Webservice server. It is possible to modify the XML content, to adapt it to the expectations of the Webservice.
