本文介绍如何在iOS应用中调用.NET WebService，包括创建Soap请求、发送POST请求，以及使用GDataXML解析返回的Soap数据。同时，文章提供了文件上传的示例代码，涉及HttpFileCollection和HttpPostedFile接口的使用。

原理根据 WebService 提供的请求示例进行编写！

不多说直接放代码下面是关键的代码：

#define my_web_address @"http://192.168.1.133/"

#define my_web_service @"CatWebService/CatUserService.asmx"

#define my_web_namespace @"http://www.xxxx.com/"

//返回Soap Body

+(NSString *)getSoapBody:(NSString *)funcationName parameter:(NSString *)content

{

if(content == nil)

{

content = @"";

}

return [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=\"%@\">"

"%@"

"</%@>"

"</soap:Body></soap:Envelope>",funcationName,my_web_namespace,content,funcationName];

}

//返回SoapBody URL Request 信息

+(NSMutableURLRequest *)getRequest:(NSString *)funcationName parameter:(NSString *)pars

{

NSString* message = [self getSoapBody:funcationName parameter:pars];

NSString* mesLenth = [NSString stringWithFormat:@"%d",message.length];

NSString* funurl = [NSString stringWithFormat:@"%@%@",my_web_namespace,funcationName];

NSURL* url = [NSURL URLWithString:[self getWSDLURL]];

// NSLog(@"url is :%@",url);

// NSLog(@"SOAPAction is %@: ",funurl);

// NSLog(@"SoapBoay:%@",message);

NSMutableURLRequest* request = [NSMutableURLRequest requestWithURL:url];

[request addValue:@"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];

[request addValue:funurl forHTTPHeaderField:@"SOAPAction"];

[request addValue:mesLenth forHTTPHeaderField:@"Content-Length"];

[request setHTTPMethod:@"POST"];

[request setHTTPBody:[message dataUsingEncoding:NSUTF8StringEncoding]];

return request;

}

其实有了上面的两个方法差不多

用NSURLConnection 就可以访问 WebService 了

NSMutableURLRequest* request = [WebServiceHelper getRequest:funNameparameter:funpars];

[NSURLConnectionconnectionWithRequest:requestdelegate:self];

我自己写了个类只不多是对 NSUrlConnection 和对结果查询进行了封装下载地址: http://download.youkuaiyun.com/detail/li6185377/4345010

里面还附带了对文件的上传是别人写的我就合并了

因为返回的数据是Soap 数据所以我用GDataXml 对数据进行解析

如果你们要直接用我的文件的化记得加上GDATAXML

使用例子：

WebServiceHelper* service = [[[WebServiceHelper alloc]initWebService:@"login"] autorelease];

[service addParameterForString:@"username" value:txt_username.text];

[service addParameterForString:@"password" value:txt_password.text];

service.delegate = self;

[service startASynchronous];

要记得加上回调函数

-(void)requestFinished:(WebServiceHelper *)request

{

NSString* result = [request getSimpleResult];

NSArray *array = [result componentsSeparatedByString:@"{h}"];

NSString* code = [array objectAtIndex:0];

if(code.intValue == 1)

{

NSString* userinfo = [array objectAtIndex:1];

UserModel* model = [[UserModel alloc]initWithXmlData:userinfo];

[AppManager sharedManager].currentUserModel = model;

[model release];

[WToast showWithText:@"登陆成功！"];

[LoginController hideLoginController];

}

else if(code.intValue == -1)

{

[WToast showWithText:@"请核对账号密码后登陆。"];

}

else {

[WToast showWithText:@"系统繁忙！请稍后登陆。"];

}

-(void)requestFailed:(WebServiceHelper *)request

{

[WToast showWithText:@"系统繁忙！请稍后登陆。"];

NSLog(@"%@",request.error.debugDescription);

}

这是对应上传的 WebService 的方法

[WebMethod]
public string upload()
{
try
{
HttpFileCollection httpFiles = Context.Request.Files;
HttpPostedFile filePhoto = httpFiles["photo"];
string localPhotoFile = Server.MapPath(String.Format("imagefiles/{0}/{1}", "Food", filePhoto.FileName));
filePhoto.SaveAs(localPhotoFile);

NameValueCollection formVars = Context.Request.Form;
string Msg = formVars["message"];
File.WriteAllText("C:/sg.txt", Msg);
return "ok";
}
catch (System.Exception ex)
{
return "error " + ex.Message;
}
}
