将图像上传到WCF服务抛出iPhone xCode [英] Upload Image to WCF service throw iPhone xCode

问题描述

大家好，





希望它回答问题的正确位置，它在.Net和xCode编程之间混合。





我发布了使用iphone上传图片投放网络服务的问题。





我已经完成了从asp.net到WCF的纯粹调用。

我需要从iPhone完成它到wcf



我的工作样本



WCF：

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:

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;
           }
       }

从ASP.NET调用：

Calling from ASP.NET :

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();
    }
}

我已经完成搜索从xCode做同样的事情

该文件已上传，但文件不正确，尺寸为differanet



以下我做过的样本

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

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);

希望有帮助

感谢所有

Hope that help
thanks all

推荐答案

您可以配置对IIS Express的远程访问

我搜索它：

http：//开发人员.xamarin.com / guides / cross-platform / application_fundamentals / web_services / walkthrough_working_with_WCF / [ ^ ]

you can Configuring Remote Access to IIS Express
I search it:
