Can't change content type of PUT file from octet/stream to image/jpeg about afamazons3manager HOT 4 CLOSED

Content-Type is a header, not a parameter. The correct MIME type should be automatically provided if the file extension is .jpg or .jpeg. If not, the request serializer can override this.

You are sure this is the case for PUT, not POST? The code in AFAmazonS3Manager is this:

 NSData *data = [NSURLConnection sendSynchronousRequest:fileRequest returningResponse:&response error:&fileError];

If I log the mimetype:

NSLog(@"mimetype is %@", [response MIMEType]); // for me this shows "image/jpeg" for the local file

then POST OR PUT:

POST uses

[formData appendPartWithFileData:data name:@"file" 
fileName:[filePath lastPathComponent] mimeType:[response MIMEType]];

but PUT does

request = [self.requestSerializer requestWithMethod:method URLString:[[self.baseURL URLByAppendingPathComponent:destinationPath] absoluteString] parameters:nil error:nil];

    // S3 expects parameters as headers for PUT requests
    if (parameters != nil) {
        for (id key in parameters) {
            [request setValue:[parameters objectForKey:key] forHTTPHeaderField:key];
        }
    }

    request.HTTPBody = data;

The ".jpg" is at the end of destinationPath...is that how the request serializer is supposed to figure out the mime type? A custom request serializer is required here?

This seems like a bug or a lack of functionality. putObject doesn't allow for setting headers that factor into the auth signature because the headers (passed as parameters) are set on the request after the auth signature is generated. This leads to a 403 from S3.

You can subclass the request serializer but it ends up duplicating code. Even then you can only set headers that are derived from information that's in the request like Content-Type from file extension or an MD5 hash. You can't specify 'x-amz-acl' header for instance.

Would love for this to be fixed.
