制作iPhone的SOAP应用的详细教程

核心提示：//封装soap请求消息 5. NSString *soapMessage = [NSString stringWithFormat: 6. @"n" 7. "n" 8. "n" 9. "n" 10. "%@n" 11.

//封装soap请求消息 5. NSString *soapMessage = [NSString stringWithFormat: 6. @"n" 7. "n" 8. "n" 9. "n" 10. "%@n" 11. "n" 12. "n" 13. "n",nameInput.text 14. ]; 15. NSLog(soapMessage); 16. //请求发送到的路径 17. NSURL *url = [NSURL URLWithString:@"http://www.nanonull.com/TimeService/TimeService.asmx"]; 18. NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url]; 19. NSString *msgLength = [NSString stringWithFormat:@"%d", [soapMessage length]]; 20. 21. // 以下对请求信息添加属性前四句是必有的，第五句是soap信息。 22. [theRequest addValue: @"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"]; 23. [theRequest addValue: @"http://www.Nanonull.com/TimeService/getOffesetUTCTime" forHTTPHeaderField:@"SOAPAction"]; 24. 25. [theRequest addValue: msgLength forHTTPHeaderField:@"Content-Length"]; 26. [theRequest setHTTPMethod:@"POST"]; 27. [theRequest setHTTPBody: [soapMessage dataUsingEncoding:NSUTF8StringEncoding]]; 28. 29. // 请求 30. NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; 31. 32. // 如果连接已经建好，则初始化data 33. if( theConnection ) 34. { 35. webData = [[NSMutableData data] retain]; 36. } 37. else 38. { 39. NSLog(@"theConnection is NULL"); 40. } 41. 42. 43. }

这个方法作用就是封装soap请求,并向服务器发送请求.

代码有注释.不重复讲解.soap并不难,难的是没有案例告诉我们怎么把其它平台的 soap移植过来,这里我给出了代码,我相信对iphone开发人员的话应该能看懂了.我在下面会把此案例的源代码附上.如果自己做不出来再看我的代码. 如果我这样讲您觉得不够细,那说明您的iphone开发还不是太深入,那么您应该用不到soap技术.可以飘过了.

下面的代码是接收信息并解析, 显示到用户界面

代码

1. -(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response 2. { 3. [webData setLength: 0]; 4. NSLog(@"connection: didReceiveResponse:1"); 5. } 6. -(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data 7.
