General Usage of AFNetworking and afnetworking

AFNetworking is a powerful network library for iOS, macOS, watchOS, and tvOS. It is built on the base URL loading system, extends the powerful advanced network abstraction, and builds it into Cocoa. It has a modular architecture, well-designed and powerful api

Introduction Using CocoaPods

pod 'AFNetworking', '~> 3.0'

• Create a download task

NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];NSURL *URL = [NSURL URLWithString:@"http://example.com/download.zip"];NSURLRequest *request = [NSURLRequest requestWithURL:URL];NSURLSessionDownloadTask *downloadTask = [manager downloadTaskWithRequest:request progress:nil destination:^NSURL *(NSURL *targetPath, NSURLResponse *response) {    NSURL *documentsDirectoryURL = [[NSFileManager defaultManager] URLForDirectory:NSDocumentDirectory inDomain:NSUserDomainMask appropriateForURL:nil create:NO error:nil];    return [documentsDirectoryURL URLByAppendingPathComponent:[response suggestedFilename]];} completionHandler:^(NSURLResponse *response, NSURL *filePath, NSError *error) {    NSLog(@"File downloaded to: %@", filePath);}];[downloadTask resume];

• Create an upload task

NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];NSURL *URL = [NSURL URLWithString:@"http://example.com/upload"];NSURLRequest *request = [NSURLRequest requestWithURL:URL];NSURL *filePath = [NSURL fileURLWithPath:@"file://path/to/image.png"];NSURLSessionUploadTask *uploadTask = [manager uploadTaskWithRequest:request fromFile:filePath progress:nil completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) {    if (error) {        NSLog(@"Error: %@", error);    } else {        NSLog(@"Success: %@ %@", response, responseObject);    }}];[uploadTask resume];

• Create an upload task and obtain the current upload progress

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];

• Create a data task

NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];NSURL *URL = [NSURL URLWithString:@"http://httpbin.org/get"];NSURLRequest *request = [NSURLRequest requestWithURL:URL];NSURLSessionDataTask *dataTask = [manager dataTaskWithRequest:request completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) {    if (error) {        NSLog(@"Error: %@", error);    } else {        NSLog(@"%@ %@", response, responseObject);    }}];[dataTask resume];

• Normal Data Request

NSString *URLString = @"http://example.com";NSDictionary *parameters = @{@"foo": @"bar", @"baz": @[@1, @2, @3]};[[AFHTTPRequestSerializer serializer] requestWithMethod:@"GET" URLString:URLString parameters:parameters error:nil];/** GET http://example.com?foo=bar&baz[]=1&baz[]=2&baz[]=3 */[[AFHTTPRequestSerializer serializer] requestWithMethod:@"POST" URLString:URLString parameters:parameters error:nil];/**POST http://example.com/Content-Type: application/x-www-form-urlencodedfoo=bar&baz[]=1&baz[]=2&baz[]=3*/

• Monitor network status

 

[[AFNetworkReachabilityManager sharedManager] setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {    NSLog(@"Reachability: %@", AFStringFromNetworkReachabilityStatus(status));}];[[AFNetworkReachabilityManager sharedManager] startMonitoring];

 

• Invalid SSL Certificate

 

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];manager.securityPolicy.allowInvalidCertificates = YES; // not recommended for production
