AFNetworking 3.x post request with data and image - ios

Question

I want to send a post request to my backend that contains some data and an UIImage as NSData Object. Problem is, I have no idea how to to that with AFNetworking 3.0.
My code so far:
NSString *url = [NSString stringWithFormat:#"%#%#", baseURL, #"/postProjectNote"];
NSMutableDictionary *dic = [[NSMutableDictionary alloc]init];
[dic setObject:session forKey:#"session"];
[dic setObject:timestamp forKey:#"timestamp"];
[dic setObject:project_id forKey:#"project_id"];
[dic setObject:type forKey:#"type"];
NSData imagedata = UIImageJPEGRepresentation(myUIImage, 0.8);
I don't need any sort of progress bar. I just need an result if the request was successful or not. The backend (Laravel 5) gives me a json string. I need to sent it with form-data.
Can you help me getting started?

Answer 1

Use this code to post an image using AFNetworking:
AFHTTPRequestOperationManager* manager = [[AFHTTPRequestOperationManager alloc] init];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:#"application/json"];
NSData *imageData = UIImageJPEGRepresentation(image, 0.5);
NSMutableDictionary *paramDict = [NSMutableDictionary new]; // Add additional parameters here
AFHTTPRequestOperation *op = [manager POST:UPDATE_PROFILE_IMAGE parameters:paramDict constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithFileData:imageData name:#"file" fileName:#"filename" mimeType:#"image/jpeg"];
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
if (success) {
// Success
}
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
// Failure
}];
[op start];

NSData *imageData = UIImageJPEGRepresentation(image, 0.5);
AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc]initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
[manager.requestSerializer setValue:token forHTTPHeaderField:#"Authorization"];
[manager.requestSerializer setCachePolicy:NSURLRequestReloadIgnoringLocalCacheData];
manager.responseSerializer.acceptableContentTypes =[NSSet setWithObjects:#"text/html",#"application/json",nil];
[manager POST:encoded parameters:"the params you want to pass" constructingBodyWithBlock:^(id<AFMultipartFormData> _Nonnull formData) {
[formData appendPartWithFileData:imageData
name:"image name with timestamp"
fileName:#"image_upload_file"
mimeType:[NSString mimeTypeForImageData:data]];
} progress:^(NSProgress * _Nonnull uploadProgress) {
//DLog(#"Progress = %#",uploadProgress);
} success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
//DLog(#"Response = %#",responseObject);
completion(YES,responseObject,nil);
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
completion(NO,nil,error);
//DLog(#"Error: %#", error);
}];
