How to make a GET request via AFNetworking?

Question

I added the AFNetworking and UIKit+AFNetworking directories to the project UIKit+AFNetworking . I am using the latest library 3.0.4

After I imported the AFNetworking.h file into my .m class file. I found many examples of how to query the url, but the information is out of date.

How to make a GET request to a URL and get data from the server? AFHTTPRequestOperation has AFHTTPRequestOperation been removed.

This is the first time we are working with libraries in xcode, I am starting.

Answer 1

 AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:[NSURL URLWithString:@"http://google.com/"]]; NSMutableURLRequest *request = [httpClient requestWithMethod:@"GET" path:@"http://google.com/api/pigs/" parameters:nil]; AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request]; [httpClient registerHTTPOperationClass:[AFHTTPRequestOperation class]]; [operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) { // Print the response body in text NSLog(@"Response: %@", [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding]); } failure:^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"Error: %@", error); }]; [operation start]; 

===============================================

You can also use AFHTTPRequestOperation:

 NSOperationQueue *networkQueue = [[NSOperationQueue alloc] init]; networkQueue.maxConcurrentOperationCount = 5; NSURL *url = [NSURL URLWithString:@"https://example.com"]; NSURLRequest *request = [NSURLRequest requestWithURL:url]; AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request]; [operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) { NSString *string = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding]; NSLog(@"%@", string); } failure:^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"%s: AFHTTPRequestOperation error: %@", __FUNCTION__, error); }]; [networkQueue addOperation:operation];

For AFNetworking 3.x:

 AFHTTPSessionManager *manager = [AFHTTPSessionManager manager]; [manager GET:@"http://example.com/resources.json" parameters:nil progress:nil success:^(NSURLSessionTask *task, id responseObject) { NSLog(@"JSON: %@", responseObject); } failure:^(NSURLSessionTask *operation, NSError *error) { NSLog(@"Error: %@", error); }]; 

Answer 3

 please try below answer. +(void)callAFWS:(NSDictionary *)dict withURL:(NSString *)strUrl withToken:(NSString *)strToken withBlock:(dictionary)block { AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc]initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]]; [manager.requestSerializer setValue:strToken forHTTPHeaderField:@"Authorization"]; [manager GET:[NSString stringWithFormat:@"%@/%@",WebserviceUrl,strUrl] parameters:dict progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) { if (!responseObject) { NSMutableDictionary *dict = [[NSMutableDictionary alloc] init]; [dict setObject:ServerResponceError forKey:@"error"]; block(responseObject); return ; } block(responseObject); } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) { NSMutableDictionary *dict = [[NSMutableDictionary alloc] init]; [dict setObject:ServerResponceError forKey:@"error"]; block(dict); }]; } 

Answer 4

With AFNetworking 3.0 you need to make a request like:

 NSURL * urlStr = [NSURL URLWithString:strURL]; NSDictionary *dictParameters = @{@"user[height]": height,@"user[weight]": weight}; AFHTTPSessionManager * manager = [AFHTTPSessionManager manager]; [manager GET:url.absoluteString parameters:dictParameters success:^(NSURLSessionTask *task, id responseObject) { NSLog(@"PLIST: %@", responseObject); } failure:^(NSURLSessionTask *operation, NSError *error) { NSLog(@"Error: %@", error); }]; 

Answer 5

 (void)postDatabyAF{ NSString *url; NSDictionary *dict; AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; manager.responseSerializer = [AFJSONResponseSerializer serializer]; manager.responseSerializer = [AFJSONResponseSerializer serializerWithReadingOptions: NSJSONReadingAllowFragments]; [manager POST:url parameters:dict success:^(AFHTTPRequestOperation * _Nonnull operation, id _Nonnull responseObject) { NSLog(@" operation.responseData %@",operation.responseData); NSLog(@" operation.response %@",operation.response); NSLog(@"statusCode %ld",operation.response.statusCode); } failure:^(AFHTTPRequestOperation * _Nullable operation, NSError * _Nonnull error) { if (error) { } else{ } }];
