How to send a array as a parameter to a web service using SOAP and objective C.
- by Alejandra Meraz
I'm working in a iPhone app that needs to send a array as a parameter using SOAP.
this is the current request and connection:
NSString *soapMessage = [NSString stringWithFormat:
@"<?xml version=\"1.0\" encoding=\"utf-8\"?>\n"
"<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/\">\n"
"<soap:Body>\n"
"<function xmlns=\"http://tempuri.org/\" />\n"
"</soap:Body>\n"
"</soap:Envelope>\n"];
NSURL *url = [NSURL URLWithString:@"http://myHost.com/myWebService/service.asmx"]; //the url to the WSDL
NsMutableURLRequest theRequest = [[NSMutableURLRequest alloc] initWithURL:url];
NSString *msgLength = [NSString stringWithFormat:@"%d",[soapMessage length]];
[theRequest addValue:@"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
[theRequest addValue:msgLength forHTTPHeaderField:@"Content-Lenght"];
[theRequest setHTTPMethod:@"POST"];
[theRequest addValue:@"myhost.com" forHTTPHeaderField:@"Host"];
[theRequest addValue:@"http://tempuri.org/function" forHTTPHeaderField:@"SOAPAction"];
[theRequest setHTTPBody:[soapMessage dataUsingEncoding:NSUTF8StringEncoding]];
theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
Now, to send parameters I looked at the WSDL of the function description for the input is like this:
<s:complexType name="ArrayOfDictionaryEntry">
<s:sequence>
<s:element minOccurs="0" maxOccurs="unbounded" name="DictionaryEntry" type="tns:DictionaryEntry" />
</s:sequence>
</s:complexType>
<s:complexType name="DictionaryEntry">
<s:sequence>
<s:element minOccurs="0" maxOccurs="1" name="Key" />
<s:element minOccurs="0" maxOccurs="1" name="Value" />
</s:sequence>
</s:complexType>
<s:element name="functionInput">
<s:complexType />
</s:element>
I guess then that I need to make a array of dictionary entries.
what I would like to send is something like this
[ location => USA,
module => DEVELOPMENT]
But I'm kind of confused.
the array is created outside the
SOAP, like an NSArray or inside the
SoapMessage?
if so... How is it done?
and the DictionaryEntry, should I
make a class?
thanks for your time n.n
