AFNetworking Json post image - ios

Question

I studied with objective C programming . I don't know how to post image from the library to the api json (I took the picture from library use UIImagePickerController) . Thanks!
My json api:
http://i.stack.imgur.com/DLKZG.png
- (IBAction)btnAddBook:(id)sender {
AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:[NSURL URLWithString:#"http://192.168.1.54"]];
NSData *imageData = UIImageJPEGRepresentation(self.ivPickedImage.image, 1);
NSMutableDictionary *params = [[NSMutableDictionary alloc]init];
[params setValue:self.tfTitle.text forKey:#"title"];
[params setValue:self.tfPrice.text forKey:#"price"];
[params setValue:self.tfProem.text forKey:#"proem"];
[params setValue:#"Vietnamese" forKey:#"language"];
AFHTTPRequestOperation *op = [manager POST:#"/api/books" parameters:params constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithFileData:imageData name:#"file" fileName:#"photo.jpg" mimeType:#"image/jpeg"];
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"Success: %# ***** %#", operation.responseString, responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %# ***** %#", operation.responseString, error);
}];
[op start];

Answer 1

Please use this below code:
NSDictionary *requestDictionary = [NSDictionary dictionaryWithObjectsAndKeys:abc.text, #"firstkey",xyz.text, #"secondkey" nil];
NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:#"POST" URLString:#"YOUR API URL" parameters:requestDictionary constructingBodyWithBlock:^(id<AFMultipartFormData> formData)
{ [formData appendPartWithFileData:imageData name:#"profile_pic" fileName:#"photo.jpg" mimeType:#"image/jpeg"];
}
} error:nil];
AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
NSProgress *progress = nil;
NSURLSessionUploadTask *uploadTask = [manager uploadTaskWithStreamedRequest:request progress:&progress completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) {
NSLog(#"%#", response);
if (error) {
} else {
}
}];
[uploadTask resume];
Hope this helps.

By using AFNetworking multipart request. you can post image as data. here are the completed block of how to post image as multipart using AFNetworking
NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:#"POST" URLString:#"http://example.com/upload" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithFileURL:[NSURL fileURLWithPath:#"file://path/to/image.jpg"] name:#"file" fileName:#"filename.jpg" mimeType:#"image/jpeg" error:nil];
} error:nil];
AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
NSURLSessionUploadTask *uploadTask;
uploadTask = [manager
uploadTaskWithStreamedRequest:request
progress:^(NSProgress * _Nonnull uploadProgress) {
// This is not called back on the main queue.
// You are responsible for dispatching to the main queue for UI updates
dispatch_async(dispatch_get_main_queue(), ^{
//Update the progress view
[progressView setProgress:uploadProgress.fractionCompleted];
});
}
completionHandler:^(NSURLResponse * _Nonnull response, id _Nullable responseObject, NSError * _Nullable error) {
if (error) {
NSLog(#"Error: %#", error);
} else {
NSLog(#"%# %#", response, responseObject);
}
}];
[uploadTask resume];
AFNetworking
Here your image is not passed as JSON. By using AFNetworking multipart request, all your request parameter passed as JSON and Image/Video that passed as NSData. where NSData is divided in multiple packets.
Thanks
