Using Soap with iOS

I plan to use WSLD2OBJC in an enterprise application to use SOAP-based services. But the last update for wsdl2objc was in 2010.

  • Is wsdl2objc safe for use in a corporate application?
  • Are there any other reliable components for parsing soap?
  • or can I use a simple XML query with NSXMLParse for my needs?

First of all, WSLD2OBJC is too bloated to use

1) In general, SOAP itself is unsafe if the message is not encrypted. Given this SOAP body from someSOAPmethod , if you use the [WebMethod] attribute in .NET with SOAP v1.0:

 POST /WebService/Common.asmx HTTP/1.1 Host: localhost Content-Type: text/xml; charset=utf-8 Content-Length: length SOAPAction: "http://example.com/someSOAPmethod" <?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> <SomeSOAPmethod xmlns=\"http://example.com/\"> <encryptedMessage>%@</encryptedMessage> //<-- this is vary, depends on your parameter </SomeSOAPmethod> </soap:Body> </soap:Envelope>

% @ must pass with encrypted data to protect SOAP. You can use any type of encryption, but I prefer AES . To provide even greater addition of HTTPS connection (RSA encryption).

2) Instead, you can use your own parsing using WSLD2OBJC. From the example of someSOAPmethod .

 -(NSMutableURLRequest *)encapsulateSOAP:(NSString *)encryptedMessage withSoapMethod:(NSString *)soapMethod andBaseURL:(NSURL *)baseURL { NSString* soapMessage = [NSString stringWithFormat:@"<?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><%@ xmlns=\"http://example.com/\"><encryptedMessage>%@</encryptedMessage></%@></soap:Body></soap:Envelope>", soapMethod, encryptedMessage, soapMethod]; NSString* msgLength = [NSString stringWithFormat:@"%d", [soapMessage length]]; NSMutableURLRequest* theRequest = [NSMutableURLRequest requestWithURL:baseURLl]; [theRequest addValue:@"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"]; [theRequest addValue:[NSString stringWithFormat:@"%@%@", @"http://example.com/", soapMethod ] forHTTPHeaderField:@"SOAPAction"]; [theRequest setHTTPMethod:@"POST"]; [theRequest addValue:msgLength forHTTPHeaderField:@"Content-Length"]; [theRequest setHTTPBody: [soapMessage dataUsingEncoding:NSUTF8StringEncoding]]; [theRequest setTimeoutInterval:10]; return theRequest; }

How to use the above method:

  NSString *encryptedMessage = //some encrypted message NSString *soapMethod = @"someSOAPmethod"; NSURL *baseURL = [NSURL urlWithString:@"http://example.com"]; NSMutableURLRequest *requestQueue = [self encapsulateSOAPRequest:encryptedMessage withSoapMethod:soapMethod andBaseURL:baseURL]; //then request using AFNetworking, ASIHTTP or your own networking library

3) Yes, you can use NSXMLParse or any third-party library that you want to link to the SOAP request or cancel the SOAP response.
