iOS中的Soap请求

主要就是封装soap请求消息，然后解析返回的xml，具体的实现请参考附件，下面只列出soap请求的核心代码。

 

- (void)getOffesetUTCTimeSOAP {
	recordResults = NO;
	//封装soap请求消息
	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"
							 "<getOffesetUTCTime xmlns=\"http://www.Nanonull.com/TimeService\">\n"
							 "<hoursOffset>%@</hoursOffset>\n"
							 "</getOffesetUTCTime>\n"
							 "</soap:Body>\n"
							 "</soap:Envelope>\n", nameInput.text
							 ];
	//请求发送到的URL
	NSURL *url = [NSURL URLWithString:@"http://www.nanonull.com/TimeService/TimeService.asmx"];
	NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url];
	NSString *msgLength = [NSString stringWithFormat:@"%d", [soapMessage length]];
	
	//对请求信息添加属性,这是必有的，第五句是soap信息。
	[theRequest addValue: @"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
	[theRequest addValue: @"http://www.Nanonull.com/TimeService/getOffesetUTCTime" forHTTPHeaderField:@"SOAPAction"];
	
	[theRequest addValue: msgLength forHTTPHeaderField:@"Content-Length"];
	[theRequest setHTTPMethod:@"POST"];
	[theRequest setHTTPBody: [soapMessage dataUsingEncoding:NSUTF8StringEncoding]];
	
	//请求
	NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
	
	if(!theConnection)
		NSLog(@"theConnection is NULL");	
}
