アプリケーションからサーバーに情報、具体的にはテキスト形式のaとbを渡す必要があります。WCFサービスのコードは次のとおりです。
public class iOSService
{
// To use HTTP GET, add [WebGet] attribute. (Default ResponseFormat is WebMessageFormat.Json)
// To create an operation that returns XML,
// add [WebGet(ResponseFormat=WebMessageFo rmat.Xml)],
// and include the following line in the operation body:
// WebOperationContext.Current.Outgoin gResponse.ContentType = "text/xml";
[OperationContract]
public void DoWork()
{
// Add your operation implementation here
return;
}
// Add more operations here and mark them with [OperationContract]
[OperationContract]
public string iOSTest2(string a, string b)
{
string res = "";
try
{
res=(int.Parse(a) + int.Parse(b)).ToString();
}
catch (Exception exp)
{
res = "Not a number";
}
return res;
}
}
aとbを受信した後、サーバーはそれらを追加し、それらの合計を送り返します。
そして、iOSアプリケーションのサーバーにパラメーターを送信するための私のコードは次のとおりです。
- (IBAction)test:(id)sender {
NSArray *propertyNames = [NSArray arrayWithObjects:@"23", @"342", nil];
NSArray *propertyValues = [NSArray arrayWithObjects:@"a", @"b", nil];
NSDictionary *properties = [NSDictionary dictionaryWithObjects:propertyNames forKeys:propertyValues];
NSMutableArray * arr;
arr=[[NSMutableArray alloc]initWithObjects:properties, nil];
NSLog(@"%@",arr);
NSError * error;
NSData *jsonData2 = [NSJSONSerialization dataWithJSONObject:arr options:NSJSONWritingPrettyPrinted error:&error];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://www.mathforyou.net/iOSservice.svc/iOSTest2"]];
NSString *jsonString = [[NSString alloc] initWithData:jsonData2 encoding:NSUTF8StringEncoding];
[request setValue:@"appliction/json" forHTTPHeaderField:@"Content-Type"];
[request setHTTPMethod:@"POST"];
[request setHTTPBody:jsonData2];
NSLog(@"JSON String: %@",jsonString);
NSError *errorReturned = nil;
NSURLResponse *theResponse =[[NSURLResponse alloc]init];
NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:&theResponse error:&errorReturned];
if (errorReturned) {
//...handle the error
NSLog(@"error");
}
else {
NSString *retVal = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(@"%@",retVal);
}
}
しかし、サーバーは私に次のメッセージに答えます。
"ExceptionDetail":null,"ExceptionType":null,"Message":"The server was unable to process the request due to an internal error. For more information about the error, either turn on IncludeExceptionDetailInFaults (either from ServiceBehaviorAttribute or from the <serviceDebug> configuration behavior) on the server in order to send the exception information back to the client, or turn on tracing as per the Microsoft .NET Framework SDK documentation and inspect the server trace logs.","StackTrace":null
Xcodeからのログは次のとおりです。

PS私は友人に助けを求めましたが、彼はObjective-cがC ++専用のプログラムを作成し、コードが機能することを知らないため、サーバーに問題はありません。コードは次のとおりです。
string data = "{\"a\":\"560\",\"b\":\"90\"}";
byte[] bd = Encoding.UTF8.GetBytes(data);
HttpWebRequest wr = (HttpWebRequest)HttpWebRequest.Create("http://www.mathforyou.net/IOSService.svc/iOSTest2");
wr.ContentType = "application/json";
wr.Method = "POST";
wr.ContentLength = bd.Length;
Stream sw = wr.GetRequestStream();
sw.Write(bd, 0, bd.Length);
sw.Close();
HttpWebResponse resp = (HttpWebResponse)wr.GetResponse();
Stream s = resp.GetResponseStream();
byte[] bres = new byte[resp.ContentLength];
s.Read(bres, 0, bres.Length);
string ans = Encoding.UTF8.GetString(bres);
Console.WriteLine(ans);
助けてください、私は疲れています。
