Question

我一直在尝试使用肥皂和肥皂12，但错误似乎总是出现。我一直在这里寻找帮助，我“完全”像他们说我应该这样做，但它对我不起作用。我想如果有人能读我的代码。我刚开始使用objective-c所以请详细解释。谢谢！

问题：

什么都没发生，一切都停在：“收到的字节：0
服务器无法为请求提供服务，因为我不支持该媒体

我的代码如下：

#import "ViewController.h"


@interface ViewController () {

}

@end

@implementation ViewController

@synthesize username, password, conWebData, soapResults, xmlParser;


- (IBAction)Login:(UIButton *)sender {


    NSString *soapMessage = [NSString stringWithFormat:

我的网络服务：zermattproject.azurewebsites.net/WebService1.asmx?op=Login

有什么问题？每次我尝试解决问题时，会出现另一个问题。谁能明白为什么？

此方法将创建用于发送服务并获得响应的参数

- (void)sendRequest
{
    // Create Paramters to Send
    NSDictionary *dictParams = [NSDictionary dictionaryWithObjectsAndKeys:@"Shree",@"UserName",@"s123",@"Password", nil];

    // Create SOAP Message by calling method with action name
    NSString *reqSOAPmsg = [self createSoapMesssageFrom:dictParams andAction:@"Login"];

    NSURL *url = [NSURL URLWithString:@"http://www.zermattproject.azurewebsites.net/WebService1.asmx"]; // write your webservice domain address upto .asmx file

    NSURLRequest *soap_request = [NSMutableURLRequest requestWithURL:url];
    NSString *msgLength = [NSString stringWithFormat:@"%d", [reqSOAPmsg length]];

    [soap_request addValue: @"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
    [soap_request addValue: [NSString stringWithFormat:@"%@/%@",TEMP_URL,self.currentAction] forHTTPHeaderField:@"SOAPAction"];
    [soap_request addValue: msgLength forHTTPHeaderField:@"Content-Length"];
    [soap_request setHTTPMethod:@"POST"];
    [soap_request setHTTPBody: [reqSOAPmsg dataUsingEncoding:NSUTF8StringEncoding]];

    NSError *error;
    NSURLResponse *response;
    NSData *urlData=[NSURLConnection sendSynchronousRequest:soap_request returningResponse:&response error:&error];
    NSString *data=[[NSString alloc]initWithData:urlData encoding:NSUTF8StringEncoding];
    NSLog(@"RESPONSE : %@",data);
}

Foloowing Method使用Paramter Dictionary

创建SOAP消息

-(NSString *)createSoapMesssageFrom:(NSDictionary *)requestParam andAction:(NSString *)action
{
    NSMutableString *soapMessage = [[NSMutableString alloc] init];

    [soapMessage appendFormat:@"<?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"
     "<%@ xmlns=\"http://tempuri.org/\">\n",action];

    for(NSString *key in requestParam)
    {
        [soapMessage appendFormat:@"<%@>%@</%@>\n",key,[requestParam valueForKey:key],key];
    }
    [soapMessage appendFormat:@"</%@>\n"
     "</soap:Body>\n"
     "</soap:Envelope>",self.currentAction];

    NSLog(@"%@",soapMessage);
    return soapMessage;
}

我希望它会在我使用它的时候做好工作。祝你好运
