Hi
If developing a app at times you are required to upload files. As i got stuck many times so i thought about writing most common way of uploading.
UpDate for AFNetworking 3.0
AFNetworking 3.0 is NSURLSession based.
NSMutableURLRequest *upload_request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:@"<path_URL>" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithFileData:data name:@"upload_file" fileName:@"<your_filename>" mimeType:@"text/plain"] // you file to upload
/*appendPartWithFileURL used if you want to upload large saved files and not data*/
} error:nil];
AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
NSURLSessionUploadTask *uploadFileTask;
uploadFileTask = [manager
uploadTaskWithStreamedRequest:upload_request
progress:^(NSProgress * _Nonnull uploadProgress) {
dispatch_async(dispatch_get_main_queue(), ^{
//since the call back is not on main queue we get the main queue ourself
NSLog(@"%d",uploadProgress.fractionCompleted);//Log the progress or pass it to progressview
});
}
completionHandler:^(NSURLResponse * _Nonnull response, id _Nullable responseObject, NSError * _Nullable error) {
if (error) {
NSLog(@"OOPS!!!! %@", error);
} else {
NSLog(@"%@ %@", response, responseObject);
}
}];
[uploadFileTask resume];

UpDate For AFHTTPSessionManager
_WEAKREF(self);
AFHTTPSessionManager *manager2 = [AFHTTPSessionManager manager];
manager2.requestSerializer = [AFHTTPRequestSerializer serializer];
[ manager2.requestSerializer setValue:@"multipart/form-data; boundary=0484d4db-ff8e-4ea4-a401-4589fd5a16a7" forHTTPHeaderField:@"Content-Type"];
[ manager2.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Accept"];
[ manager2.requestSerializer setValue:@"gzip" forHTTPHeaderField:@"Accept-Encoding"];
manager2.responseSerializer = [AFHTTPResponseSerializer serializer];
manager2.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"application/hal+json"];
[manager2 POST:@"http://path" parameters:idVal constructingBodyWithBlock:^(id<AFMultipartFormData> _Nonnull formData) {
_STRONGREF(strongSelf);
//for loop is for multiple images
for (NSUInteger i=0;i<strongSelf->arrayOfFiles.count;i++) {
NSString *path= <your path>
NSString *name=[NSString stringWithFormat:@"images[%d]",(uint)i];
//using appending with file URL to upload from memory
[formData appendPartWithFileURL:[NSURL fileURLWithPath:path] name:name fileName:[strongSelf-> arrayOfFiles objectAtIndex:i] mimeType:@"image/png" error:nil];//
}
} progress:^(NSProgress * _Nonnull uploadProgress) {
dispatch_async(dispatch_get_main_queue(), ^{
NSLog(@"Error: %@", uploadProgress);
});
} success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
NSLog(@"%@ ", responseObject);
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
NSLog(@"Error: %@", error);
}];
In the above code _WEAKREF(self); and _STRONGREF(strongSelf); are macros to pass weak ref of self inside block
Prerequisites :-
1. Get latest AFNetworking library Link
Suggestion:- I very strongly recommend that you first check the post service using a good REST client from Firefox or Chrome. You don’t want to bang your head over a nonworking API.
Now once you have tested your API using any REST client i suppose you have
1. Base URL e.g http:// <your domain>.com
2.Path eg /first/second
3.Header field key value pair e.g. “Source” : “web”
4.Parameter key value pair e.g. “action_name” :”postimage”
now here is a simple function just go through it and understand.
-(void)call
{
//the image name is Denise.jpg i have used image you can use any file
//just convert it to NSData in an appropriate way
UIImage *image= [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"Denise" ofType:@"jpg"]];
// getting data from image
NSData *photoData= UIImagePNGRepresentation(image);
// making AFHttpClient
AFHTTPClient *client= [AFHTTPClient clientWithBaseURL:[NSURL URLWithString:@"http://<your domain>.com/"]];
//setting headers
[client setDefaultHeader:@"multipart/form-data; charset=utf-8; boundary=0xKhTmLbOuNdArY" value:@"Content-Type"];
[client setDefaultHeader:@"source" value:@"web"];
NSMutableURLRequest *request1 = [client multipartFormRequestWithMethod:@"POST" path:@"application/uploadfile" parameters:nil constructingBodyWithBlock: ^(id <AFMultipartFormData>formData) {
//setting body
[formData appendPartWithFormData:[[NSString stringWithFormat:@"signup"] dataUsingEncoding:NSUTF8StringEncoding] name:@"action_name"];
[formData appendPartWithFormData:[[NSString stringWithFormat:@"28"] dataUsingEncoding:NSUTF8StringEncoding] name:@"id"];
[formData appendPartWithFileData:photoData name:@"file_data" fileName:@"file.png" mimeType:@"image/png"];
}];
[request1 setTimeoutInterval:180];
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request1];
[operation setUploadProgressBlock:^(NSUInteger bytesWritten, long long totalBytesWritten, long long totalBytesExpectedToWrite) {
NSLog(@"Sent %lld of %lld bytes", totalBytesWritten, totalBytesExpectedToWrite);
float progress = totalBytesWritten / (float)totalBytesExpectedToWrite;
// use this float value to set progress bar.
}];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject)
{
NSDictionary *jsons = [NSJSONSerialization JSONObjectWithData:responseObject options:kNilOptions error:nil];
NSLog(@"%@",responseObject);
NSLog(@"response headers: %@", [[operation response] allHeaderFields]);
