iOS - Increase timeout for AFHTTPRequestOperationManager

Question

I'm downloading JSON data from a very slow server. It takes about a minute to get a resoonse from the server. I use AFNetworking library and my code throws "The request timed out" error:

NSString *urlString = [NSString stringWithFormat:@"%@/account.do?JSON&sysparm_action=getRecords",baseUrlString];

    NSString *login = [[NSUserDefaults standardUserDefaults] objectForKey:@"login"];
    NSString *password = [[NSUserDefaults standardUserDefaults] objectForKey:@"password"];

    [manager setRequestSerializer:[AFHTTPRequestSerializer serializer]];
    [manager.requestSerializer setAuthorizationHeaderFieldWithUsername:login password:password];


    [manager GET:urlString parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
        NSLog(@"JSON: %@", responseObject);
        [self parseJsonWithAccountsData:responseObject];
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"Error: %@", operation.responseString);
        [self performSelectorOnMainThread:@selector(failedWithContactsDownload) withObject:nil waitUntilDone:YES];
    }];

Didn't find a way to set a timeout for AFHTTPRequestOperationManager. How can I do it?

Answer 1

Method 1.

I think the best way is to subclass AFHTTPRequestSerializer and override

- (NSMutableURLRequest *)requestWithMethod:(NSString *)method
                                 URLString:(NSString *)URLString
                                parameters:(NSDictionary *)parameters

like this:

- (NSMutableURLRequest *)requestWithMethod:(NSString *)method
                                 URLString:(NSString *)URLString
                                parameters:(NSDictionary *)parameters
{
    NSMutableURLRequest *request = [super requestWithMethod:method URLString:URLString parameters:parameters];
    [request setTimeoutInterval:YOUR_TIMEOUT_INTERVAL_HERE];

    return request;
}

and then

    NSString *urlString = [NSString stringWithFormat:@"%@/account.do?JSON&sysparm_action=getRecords",baseUrlString];

    NSString *login = [[NSUserDefaults standardUserDefaults] objectForKey:@"login"];
    NSString *password = [[NSUserDefaults standardUserDefaults] objectForKey:@"password"];

    [manager setRequestSerializer:YOUR_NEW_REQUEST_SERIALIZER_HERE];
    [manager.requestSerializer setAuthorizationHeaderFieldWithUsername:login password:password];


    [manager GET:urlString parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
        NSLog(@"JSON: %@", responseObject);
        [self parseJsonWithAccountsData:responseObject];
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"Error: %@", operation.responseString);
        [self performSelectorOnMainThread:@selector(failedWithContactsDownload) withObject:nil waitUntilDone:YES];
    }];

Method 2

NSString *urlString = [NSString stringWithFormat:@"%@/account.do?JSON&sysparm_action=getRecords",baseUrlString];

NSString *login = [[NSUserDefaults standardUserDefaults] objectForKey:@"login"];
NSString *password = [[NSUserDefaults standardUserDefaults] objectForKey:@"password"];

[manager setRequestSerializer:[AFHTTPRequestSerializer serializer]];
[manager.requestSerializer setAuthorizationHeaderFieldWithUsername:login password:password];

NSMutableURLRequest *request = [manager.requestSerializer requestWithMethod:@"GET" URLString:[[NSURL URLWithString:urlString relativeToURL:manager.baseURL] absoluteString] parameters:nil];
[request setTimeoutInterval:YOUR_TIMEOUT_INTERVAL_HERE];

AFHTTPRequestOperation *operation = [manager HTTPRequestOperationWithRequest:request success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"JSON: %@", responseObject);
    [self parseJsonWithAccountsData:responseObject];
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@", operation.responseString);
    [self performSelectorOnMainThread:@selector(failedWithContactsDownload) withObject:nil waitUntilDone:YES];
}];
[manager.operationQueue addOperation:operation];
