I know this may seem specific to the issue at hand, however, this is me trying to avoid the horrible UploadCare usage of cocoa pods which contains a significant (and rather outdated) amount of dependencies, to JUST upload a file (and subsequently download it at a later date).
I'm struggling to translate the '-F' options in the cURL command. I understand that they specify HTTP multipart POST data, but converting this into NSMutableData with the picture file attached is difficult. I keep receiving a 403 status code.
The cURL command is:
curl -F "UPLOADCARE_PUB_KEY=e84a031b3da1g560d56d" \
-F "UPLOADCARE_STORE=1" \
-F "[email protected]" https://upload.uploadcare.com/base/
My current attempt is:
NSMutableData *body = [NSMutableData data];
NSData *imageData = UIImageJPEGRepresentation(image, 0.6);
if (imageData) {
[body appendData:[@"UPLOADCARE_PUB_KEY=e84a031b3da1g560d56d" dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[@"UPLOADCARE_STORE=1" dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"file="] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:imageData];
}
NSURLSessionConfiguration *sessionConfiguration = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *session = [NSURLSession sessionWithConfiguration:sessionConfiguration delegate:self delegateQueue:nil];
NSURL *url = [NSURL URLWithString:baseUrl];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
request.HTTPMethod = @"POST";
request.HTTPBody = imageData;
NSURLSessionDataTask *uploadTask = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
NSLog(@"%@",response);
}];
[uploadTask resume];
What am I doing wrong with the NSMutableData?
A second, and related question is: Is it worth using an objective-C lib curl wrapper at all?
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:@"https://upload.uploadcare.com/base/"]];
UIImage *image = [UIImage imageNamed:@"image.jpg"];
NSData *imageData = UIImageJPEGRepresentation(image, 1.0);
[request setHTTPMethod:@"POST"];
NSString *boundary = @"unique-consistent-string";
// set Content-Type in HTTP header
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@", boundary];
[request setValue:contentType forHTTPHeaderField: @"Content-Type"];
// post body
NSMutableData *body = [NSMutableData data];
// add params (all params are strings)
[body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=%@\r\n\r\n", @"UPLOADCARE_PUB_KEY"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"%@\r\n", @"demopublickey"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=%@\r\n\r\n", @"UPLOADCARE_STORE"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"%@\r\n", @"1"] dataUsingEncoding:NSUTF8StringEncoding]];
// add image data
if (imageData) {
[body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=file; filename=image.jpg\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[@"Content-Type: image/jpeg\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:imageData];
[body appendData:[[NSString stringWithFormat:@"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
}
[body appendData:[[NSString stringWithFormat:@"--%@--\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
// setting the body of the post to the reqeust
[request setHTTPBody:body];
// set the content-length
NSString *postLength = [NSString stringWithFormat:@"%d", [body length]];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[NSURLConnection sendAsynchronousRequest:request
queue:[NSOperationQueue currentQueue]
completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) {
if (data.length > 0) {
NSLog(@"%@", [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]);
}
}];
