iOS JSON与ASPNET Web服务

任何人都可以帮我吗？我长期困扰这个问题。iOS JSON与ASPNET Web服务

我正在开发一个IOS来将JSON引入Web服务以便插入到数据库中。但未能做到。

IOS源代码

-(IBAction)signup{ 

    NSMutableDictionary * dic = [NSMutableDictionary dictionary]; 
    [dic setObject:@"0" forKey:@"account_id"]; 
    [dic setObject:@"Jin" forKey:@"first_name"]; 
    [dic setObject:@"Lim" forKey:@"last_name"]; 
    [dic setObject:@"1987-12-02" forKey:@"date_of_birth"]; 
    [dic setObject:@"M" forKey:@"account_gender"]; 
    [dic setObject:@"65" forKey:@"phone_country_id"]; 
    [dic setObject:@"123456" forKey:@"account_phone"]; 
    [dic setObject:@"[email protected]" forKey:@"account_login"]; 

    [svc execMethod:dic]; 
}

然后

-(void) execMethod:(NSMutableDictionary *)dic{ 

    NSURL * url = [NSURL URLWithString:@"http://test.biz/AccountInfo.asmx/insert_account"]; 

    //Request 
    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url]; 
    NSData* requestData = [NSJSONSerialization dataWithJSONObject:dic options:NSJSONWritingPrettyPrinted error:nil]; 

    //prepare http body 
    [request setHTTPMethod:@"POST"]; 
    [request setValue:[NSString stringWithFormat:@"%d",[requestData length]] forHTTPHeaderField:@"Content-Length"]; 
    [request setValue:@"application/json" forHTTPHeaderField:@"Accept"]; 
    [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"]; 
    [request setHTTPBody:requestData]; 

    urlConnection = [[NSURLConnection alloc]initWithRequest:request delegate:self startImmediately:YES]; 

    UIApplication *app = [UIApplication sharedApplication]; 
    app.networkActivityIndicatorVisible = YES; 
}

Web服务

{WebMethod()} _ 
{ScriptMethod(ResponseFormat:=ResponseFormat.Json, UseHttpGet:=False)}_ 
Public Function insert_account(ByVal result As Account) As String 

    Dim account As New Account 
    account = result 
    Dim msg As String 

    **Processing Result*** 

    Return "msg:'OK'" 

End Function

P/S：我用{}来代替> <为web服务方法

错误的NSLog

2012-02-02 16:25:11.433 test.biz[10642:f803] System.InvalidOperationException: insert_account Web Service method name is not valid. 
    at System.Web.Services.Protocols.HttpServerProtocol.Initialize() 
    at System.Web.Services.Protocols.ServerProtocol.SetContext(Type type, HttpContext context, HttpRequest request, HttpResponse response) 
    at System.Web.Services.Protocols.ServerProtocolFactory.Create(Type type, HttpContext context, HttpRequest request, HttpResponse response, Boolean& abortProcessing)

烦请告诉我，我有什么错完成，感谢您的帮助:)

你能从浏览器访问网页方法吗？ – AnthonyBlake 2012-02-02 11:51:47

也是，你使用的是什么版本的.net？ – AnthonyBlake 2012-02-02 11:55:24

你测试过你的网络服务吗？我的猜测是，您没有正确配置Web服务，无论是在web.config文件中还是使用注释（例如''）。我暂时把XCode项目放在一边，启动Fiddler，在那里建立请求并用它测试Web服务。 – Codo 2012-02-02 12:27:40

我找到了解决办法：

-(IBAction)signup{ 

    NSMutableDictionary * dic = [NSMutableDictionary dictionary]; 
    [dic setObject:@"0" forKey:@"account_id"]; 
    [dic setObject:@"Jin" forKey:@"first_name"]; 
    [dic setObject:@"Lim" forKey:@"last_name"]; 
    [dic setObject:@"1987-12-02" forKey:@"date_of_birth"]; 
    [dic setObject:@"M" forKey:@"account_gender"]; 
    [dic setObject:@"65" forKey:@"phone_country_id"]; 
    [dic setObject:@"123456" forKey:@"account_phone"]; 
    [dic setObject:@"[email protected]" forKey:@"account_login"]; 

    NSMutableDictionary * result = [NSMutableDictionary dictionary]; 
    [result setObject:dic forKey:@"result"]; 

    NSURL * url = [NSURL URLWithString:@"http://test.biz/AccountInfo.asmx/insert_account"]; 

    svc = [[JSONRPCService alloc] initWithURL:url]; 

    [svc execMethod:result]; 
}

只需要为JSON添加标头。
