Cancel All Operations + Afnetworking 3.0

Cancel Post request in Afnetworking 2.0

POST method return the AFHTTPRequestOperation operation. You can cancel it by calling cancel.

AFHTTPRequestOperation *post =[manager POST:nil parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
  //doing something
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
   // error handling.
}];

//Cancel operation
[post cancel];

How to immediately force cancel an NSOperation with AFNetworking?

After a full morning of digging through AFNetworking source code, it turns out that the reason my operations weren't canceling had nothing to do with the operations themselves, but rather because I've been starting the operations incorrectly all this time. I've been using

[NSOperation start];

when I should have been adding it to my HTTPRequestSingleton's operation queue:

[[[HTTPRequestSingleton sharedClient] operationQueue] addOperation:NSOperation];

Adding it to the queue allows it to be canceled properly without having to check the isCancelled property.

AFHTTPRequestOperation Cancel Request

You can use:

[operation cancel];

This is an NSOperation method that's implemented by AFNetworking.

AFNetworking 2: How to cancel a AFHTTPRequestOperationManager request?

Objective-C

[manager.operationQueue cancelAllOperations];

Swift

manager.operationQueue.cancelAllOperations()

How can I migrate in AFNetworking 3.0?

NSURL *url = [NSURL URLWithString:@"https://example.com/"];

AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:url];

NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:

                        height, @"user[height]",

                        weight, @"user[weight]",

                        nil];

[httpClient postPath:@"/myobject" parameters:params 
success:^(AFHTTPRequestOperation *operation, id responseObject) {

    NSString *responseStr = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];

    NSLog(@"Request Successful, response '%@'", responseStr);

} failure:^(AFHTTPRequestOperation *operation, NSError *error) {

    NSLog(@"[HTTPClient Error]: %@", error.localizedDescription);
}];

afnetworking 3.0 Migration: how to POST with headers and HTTP Body

I was able to figure this out myself.

Here's the solution.

First, you need to create the NSMutableURLRequest from AFJSONRequestSerializer first where you can set the method type to POST.

On this request, you get to setHTTPBody after you have set your HTTPHeaderFields. Make sure to set the body after you have set the Header fields for content-type, or else the api will give a 400 error.

Then on the manager create a dataTaskWithRequest using the above NSMutableURLRequest. Don't forget to resume the dataTask at the very end or else nothing will get sent yet. Here's my solution code, hopefully someone gets to use this successfully:

NSDictionary *body = @{@"snippet": @{@"topLevelComment":@{@"snippet":@{@"textOriginal":self.commentToPost.text}},@"videoId":self.videoIdPostingOn}};
NSError *error;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:body options:0 error:&error];
NSString *jsonString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];

AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];

NSMutableURLRequest *req = [[AFJSONRequestSerializer serializer] requestWithMethod:@"POST" URLString:[NSString stringWithFormat:@"https://www.googleapis.com/youtube/v3/commentThreads?part=snippet&access_token=%@",[[LoginSingleton sharedInstance] getaccesstoken]] parameters:nil error:nil];

req.timeoutInterval= [[[NSUserDefaults standardUserDefaults] valueForKey:@"timeoutInterval"] longValue];
[req setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[req setValue:@"application/json" forHTTPHeaderField:@"Accept"];
[req setHTTPBody:[jsonString dataUsingEncoding:NSUTF8StringEncoding]];

[[manager dataTaskWithRequest:req completionHandler:^(NSURLResponse * _Nonnull response, id  _Nullable responseObject, NSError * _Nullable error) {

    if (!error) {
        NSLog(@"Reply JSON: %@", responseObject);

        if ([responseObject isKindOfClass:[NSDictionary class]]) {
              //blah blah
        }
    } else {
        NSLog(@"Error: %@, %@, %@", error, response, responseObject);
    }
}] resume];

[[httpClient operationQueue] cancelAllOperations];

AFNetworking 3.0 migration for redirect block

Use setTaskWillPerformHTTPRedirectionBlock on AFHTTPSessionManager. The block set will be called if the initial URL request redirects. You have the option to follow the redirect, or stop the redirect in the block.

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
[manager setTaskWillPerformHTTPRedirectionBlock:^NSURLRequest * _Nonnull(NSURLSession * _Nonnull session, NSURLSessionTask * _Nonnull task, NSURLResponse * _Nonnull response, NSURLRequest * _Nonnull request) {
    NSLog(@"%@", request.URL);
    // This will be called if the URL redirects
    return request; // return request to follow the redirect, or return nil to stop the redirect
}];
[manager GET:_URLString parameters:nil progress:nil success:^(NSURLSessionTask *task, id responseObject) {
    NSLog(@"Response: %@", responseObject);
} failure:^(NSURLSessionTask *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}];

I would recommend you read through the AFNetworking 3.0 Migration Guide.
