Uploading image to server with ASIFormDataRequest


Hi build a service for my iPhone app and need to have function that get image from the user: Until now i used to get only text with this method:

string input = null; using (StreamReader sr = new StreamReader(Request.InputStream)) { input = sr.ReadToEnd(); }

How should i get the image from the post?

This is how i send the image from the iphone app:

imageRequest = [ASIFormDataRequest requestWithURL:url]; [imageRequest addData:imageData withFileName:@"someFileName.jpeg" andContentType:@"image/jpeg" forKey:@"uploadedImage"]; [imageRequest setDelegate:self]; [imageRequest setRequestMethod:@"POST"]; [imageRequest startAsynchronous];


You cannot upload image by adding image with name. First convert UIImage object into Base64Encoding string and then send that string to server.

Download supporting files from the link <a href="http://iphonesdksnippets.com/?tag=/uiimage" rel="nofollow">enter link description here</a>

and the use these methods

- (NSString*) stringFromImage:(UIImage*)image { if(image){ NSData *dataObj = UIImagePNGRepresentation(image); return [dataObj base64Encoding]; } else { return @""; } } - (UIImage*) imageFromString:(NSString*)imageString { NSData* imageData =[NSData dataWithBase64EncodedString:imageString]; return [UIImage imageWithData: imageData]; }

Also check this link for Image to string and string to image in Base64 <a href="http://iphonesdksnippets.com/post/2010/03/14/Convert-image-tofrom-text-%28Base64%29.aspx" rel="nofollow">image conversion</a>
