Iphone 如何让iOS与.NET web服务对话

我在连接此Web服务时遇到问题，是否知道我做错了什么

- (void)startRetrievingHotels 
{    
    //Create the web service URL
    NSURL *url = [NSURL URLWithString:@"https://www.stratexlive.com/tenants/commercialbank/_vti_bin/stratexws.asmx"];

    //Create the web service request
    ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];

    NSString *requestString = [self buildHotelListRequest];
    NSLog(@"%@", requestString );

    [request setDelegate:self]; 
    [request setUsername:@"asdfasdf@asdfasdf.com"];
    [request setPassword:@"asdfasdfasdfasdf$"];
    [request appendPostData:[[self buildHotelListRequest] dataUsingEncoding:NSUTF8StringEncoding]]; //Set the xml request
    [request startAsynchronous];
}

- (NSString *)buildHotelListRequest
{


    NSString *result = [NSString stringWithFormat: @"<?xml version=\"1.0\"?>"
    @"<GetUserName xmlns=\"https://www.sdf.com/\" />"];

    NSLog(@"HOTEL LIST REQUEST: %@", result);

    return result;
}

-（无效）StartrevingHotels
{    
//创建web服务URL
NSURL*url=[NSURL URLWithString:@”https://www.stratexlive.com/tenants/commercialbank/_vti_bin/stratexws.asmx"];
//创建web服务请求
ASIHTTPRequest*request=[AsiHttpRequestWithURL:url]；
NSString*requestString=[self-buildHotelListRequest]；
NSLog（@“%@”，requestString）；
[请求setDelegate:self]；
[请求设置用户名：@”asdfasdf@asdfasdf.com"];
[请求设置密码：@“asdfasdfasdfasdf$”；
[request appendPostData:[[self-buildHotelListRequest]dataUsingEncoding:NSUTF8StringEncoding]；//设置xml请求
[请求启动同步]；
}
-（NSString*）buildHotelListRequest
{
NSString*结果=[NSString stringWithFormat:@“”
@""];
NSLog（@“酒店列表请求：%@”，结果）；
返回结果；
}

这是我得到的答复：

我读了有关soap的文章，发现您缺少了一些内容。
这里有一些信息，但我不确定用户名和密码放在哪里。
希望你能弄明白

NSString *soapMessage = @"<?xml version=\"1.0\" encoding=\"utf-8\"?>\

<soap:Body>\
<GetUserName xmlns=\"https://www.stratexsystems.com/\" />\
</soap:Body>\
</soap:Envelope>";
NSURL *url = [NSURL URLWithString:@"https://www.stratexlive.com/tenants/commercialbank/_vti_bin/stratexws.asmx"];
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url];
NSString *msgLength = [NSString stringWithFormat:@"%d", [soapMessage length]];
[theRequest addValue: @"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
[theRequest addValue: @"https://www.stratexsystems.com/GetUserName" forHTTPHeaderField:@"SOAPAction"];
[theRequest addValue: msgLength forHTTPHeaderField:@"Content-Length"];
[theRequest setHTTPMethod:@"POST"];
[theRequest setHTTPBody: [soapMessage dataUsingEncoding:NSUTF8StringEncoding]];

NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];

[TheRequestSetHttpMethod:@“POST”]；
[TheRequestSetHttpBody:[soapMessage数据使用编码：NSUTF8StringEncoding]；
NSURLConnection*连接=[[NSURLConnection alloc]initWithRequest:theRequest委托：self]；

您不能使用NSURLConnection吗？@H2CO3已更新问题。Inder-我的请求将变得更加复杂，因此我更熟悉ASIHTTREQUESTAnd，现在我厌倦了水平滚动100k XML响应。请缩进。这是一个soap web服务，我对此不太了解。。sorry@TheLearnerWeb服务似乎需要某种版本信息，但您没有将其包含在请求中。医生提到了吗？你说得对。潜在的问题是必须构造整个SOAP消息，包括信封。OP的要求只包括尸体。对于复杂的请求，我不能强调ObjC中手工构建和手工解码SOAP有多痛苦。如果切换到REST是不可能的，那么我建议使用gsoap而不是手工构建这些东西。
