I am writing an iPhone app using Three20 framework, now I am using presigned url to upload images to S3, but haven't been successful.
The following is the code
- (void)uploadImage {
TTURLRequest *request = [TTURLRequest requestWithURL:_presignedUrl delegate:self];
request.httpMethod = @"POST";
request.cachePolicy = TTURLRequestCachePolicyNoCache;
request.cacheExpirationAge = TT_CACHE_EXPIRATION_AGE_NEVER;
// add the image file
[request addFile:UIImageJPEGRepresentation(_image, 1.0)
mimeType:@"image/jpeg"
fileName:_key];
[request setValue:@"MyApp/1.0" forHTTPHeaderField:@"User-Agent"];
[request setValue:@"image/jpeg" forHTTPHeaderField:@"Content-type"];
TTURLXMLResponse *response = [[TTURLXMLResponse alloc] init];
request.response = response;
[response release];
[request send];
}
The _key is the file name e.g. test.jpg
The _presignedUrl is something like the following
https://s3.amazonaws.com/<bucket name>/test.jpg?Expires=(expires)&AWSAccessKeyId= (AWSAccessKeyId)&Signature=(Signature)
And the presigned url is generated on Server side using AWS Java SDK by using GeneratePresignedUrlRequest with , test.jpg as key, and also POST as http method
Is there anything missing or wrong?
