在iPhone上使用Objective-C使用WCF Web服务

Question

我很难在我的iPhone应用程序中使用非常简单的(Hello World)WCF Web服务.根据我的阅读,您必须手动创建请求消息,然后将其发送到Web服务URL.

我能够在.asmx Web服务上完成此任务,但不能使用WCF服务.

我如何知道请求SOAP消息的正确格式？

我试图访问的Web服务格式为:http://xxx.xxx.xxx.xxx: PORT/IService1 /(在VM中本地运行)

我为缺乏信息而道歉,我很遗憾.

任何和所有的帮助非常感谢.

感谢在这里帮助的每个人.我最终搞清楚了,并认为我会分享我的结果.我知道这不是一个全面的解决方案,所以如果您需要更多细节,请给我发消息或评论.

//Variables used
NSMutableData *webData;
NSMutableString *soapResults;
NSXMLParser *xmlParser;
BOOL recordResults;

//Web Service Call
NSString *soapMessage = [NSString stringWithFormat:
@"<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n"
"<SOAP-ENV:Envelope \n"
"xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" \n"
"xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" \n" 
"xmlns:SOAP-ENC=\"http://schemas.xmlsoap.org/soap/encoding/\" \n"
"SOAP-ENV:encodingStyle=\"http://schemas.xmlsoap.org/soap/encoding/\" \n"
"xmlns:SOAP-ENV=\"http://schemas.xmlsoap.org/soap/envelope/\"> \n"
"<SOAP-ENV:Body> \n"
"<Login xmlns=\"http://tempuri.org/\"><username>JACKSON</username><password>PASSWORD</password>"
"</Login> \n"
"</SOAP-ENV:Body> \n"
"</SOAP-ENV:Envelope>"];

NSURL *url = [NSURL URLWithString:@"http://172.16.0.142:8731/Service1/"];               
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url];             
NSString *msgLength = [NSString stringWithFormat:@"%d", [soapMessage length]];          
[theRequest addValue: @"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];       
[theRequest addValue: @"http://tempuri.org/IService1/Login" forHTTPHeaderField:@"Soapaction"];
[theRequest addValue: msgLength forHTTPHeaderField:@"Content-Length"];
[theRequest setHTTPMethod:@"POST"];     
[theRequest setHTTPBody: [soapMessage dataUsingEncoding:NSUTF8StringEncoding]];
NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];

if(theConnection) {
    webData = [[NSMutableData data] retain];
}
else {
    NSLog(@"theConnection is NULL");
}

//Implement the NSURL and XMLParser protocols
#pragma mark -
#pragma mark NSURLConnection methods

- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data

- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error

- (void)connectionDidFinishLoading:(NSURLConnection *)connection

#pragma mark -
#pragma mark XMLParser methods

-(void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName 
 namespaceURI:(NSString *)namespaceURI 
qualifiedName:(NSString *)qName
   attributes:(NSDictionary *)attributeDict 

-(void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string

-(void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName 
 namespaceURI:(NSString *)namespaceURI 
qualifiedName:(NSString *)qName

我个人建议为WCF服务添加一个基于REST的端点.您可以使用SOAP同时运行它,并且在iPhone端更容易使用它.
