Hello guys,


Hope it correct place to answer question,it mix between .Net and xCode programming.


I have issue of upload image throw web service using iphone.


I have done it with pure calling from asp.net to WCF.
I need to done it from iPhone to wcf

my sample of work

WCF:
C#
public class TestService : ITestService
   {
       [WebInvoke(Method = "POST", UriTemplate = "UploadFile?fileName={fileName}")]
       public string UploadFile(string fileName, Stream fileContents)
       {
           //save file
           string absFileName = "";
           try
           {
                 absFileName = string.Format("{0}\\FileUpload\\{1}"
                                       , AppDomain.CurrentDomain.BaseDirectory
                                       , Guid.NewGuid().ToString().Substring(0,6)  + ".jpg");

              // string fld = @"h:\root\home\amrmk185-001\www\publish\WCFService\FileUpload\" + fileName;
               //System.IO.File.Create(absFileName);
                 using (FileStream fs = new FileStream(absFileName, FileMode.Create))
               {
                   fileContents.CopyTo(fs);
                   fileContents.Close();
               }
               return "Upload OK";
           }
           catch(Exception ex)
           {
               return "FAIL ==> " + ex.Message + "   " + absFileName;
           }
       }





Calling from ASP.NET :


C#
private string UploadFileToService(HttpPostedFileBase file)
{
    //specify the url with fileName parameter
   // string url = @"http://localhost:8080/TestService.svc/REST/UploadFile?fileName=" + file.FileName;
    string url = @" http://192.168.2.3/UploadImage/TestService.svc/REST/UploadFile?fileName=" + file.FileName;

   //  string url = @"http://amrmk185-001-site1.smarterasp.net/UploadMe/TestService.svc/REST/UploadFile?fileName=" + file.FileName;
    var uri = new Uri(url);



    //create HttpWebRequest
    var request = (HttpWebRequest) WebRequest.Create(uri);
    request.ContentType = "application/octet-stream";
    request.Method = WebRequestMethods.Http.Post;

    //set request stream (Content)
    using (var requestStream = request.GetRequestStream())
    {
        byte[] fileDataInByte = null;
        using (BinaryReader binaryReader = new BinaryReader(file.InputStream))
        {
            fileDataInByte = binaryReader.ReadBytes(file.ContentLength);
        }
        requestStream.Write(fileDataInByte, 0, fileDataInByte.Length);
    }

    //Call REST and get a response back
    using (var response = request.GetResponse())
    {
        StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.UTF8);
        return reader.ReadToEnd();
    }
}





I have done search to do same from xCode
The file is uploaded ,but not correct file,size is differanet

Following sample of I Have done

CSS
UIImage * img = [UIImage imageNamed:@"Stonehenge.jpg"];

    NSData *imageData = UIImageJPEGRepresentation(img,0.2);









    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://xxxxt/UploadMe/TestService.svc/REST/UploadFile?fileName=ffff.jpg"]];

    [request setHTTPMethod:@"POST"];



    NSString *boundary = @"xxxxBoundaryStringxxxx";



    NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@", boundary];

    [request addValue:contentType forHTTPHeaderField:@"Content-Type"];



    NSMutableData *body = [NSMutableData data];

    [body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];

    [body appendData:[@"Content-Disposition: form-data; name=\"userfile\"; filename=\"iphoneimage.jpg\"\r\n" dataUsingEncoding:NSUTF8StringEncoding]];

    [body appendData:[@"Content-Type: application/octet-stream\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];

    [body appendData:[NSData dataWithData:imageData]];

    [body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];

    [request setHTTPBody:body];

    [request addValue:[NSString stringWithFormat:@"%d", [imageData length]] forHTTPHeaderField:@"Content-Length"];



    NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];

    NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];

    NSLog(@"%@", returnString);

Hello Amr,

Did you manage to solve your problem? I have encountered the same problem as yours. The file copied is corrupted.
