iOS - Increase timeout for AFHTTPRequestOperationManager - ios

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

In AFNetworking 2 library there is method in AFHTTPRequestSerializer set the request time out interval directly.
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.requestSerializer setTimeoutInterval:TIME_OUT_INTERVAL];
[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];
}];
You don't need to override the class to set the request time out interval.

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];

I'm a bit lazy to categorize or subclass. You can access the manager's request serializer directly:
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.requestSerializer.timeoutInterval = INTERNET_TIMEOUT;
manager.requestSerializer.cachePolicy = NSURLRequestReloadIgnoringLocalAndRemoteCacheData;

Answer 4

Create a subclass
self.requestOperationManager.requestSerializer = [[TimeoutAFHTTPRequestSerializer alloc] initWithTimeout:30];
TimeoutAFHTTPRequestSerializer.h
#import "AFURLRequestSerialization.h"
#interface TimeoutAFHTTPRequestSerializer : AFHTTPRequestSerializer
#property (nonatomic, assign) NSTimeInterval timeout;
- (id)initWithTimeout:(NSTimeInterval)timeout;
#end
TimeoutAFHTTPRequestSerializer.m
#import "TimeoutAFHTTPRequestSerializer.h"
#implementation TimeoutAFHTTPRequestSerializer
- (id)initWithTimeout:(NSTimeInterval)timeout {
self = [super init];
if (self) {
self.timeout = timeout;
}
return self;
}
- (NSMutableURLRequest *)requestWithMethod:(NSString *)method
URLString:(NSString *)URLString
parameters:(NSDictionary *)parameters
error:(NSError *__autoreleasing *)error
{
NSMutableURLRequest *request = [super requestWithMethod:method URLString:URLString parameters:parameters error:error];
if (self.timeout > 0) {
[request setTimeoutInterval:self.timeout];
}
return request;
}
#end

Actually, the value of timeoutInterval property is ignored - I've checked by debugging the method requestWithMethod:URLString:parameters:error:
I managed to subclass and override the method (Swift)
class RequestSerializer: AFHTTPRequestSerializer {
override func requestWithMethod(method: String!, URLString: String!, parameters:AnyObject!, error: NSErrorPointer) -> NSMutableURLRequest {
var req = super.requestWithMethod(method, URLString: URLString, parameters: parameters, error: error)
req.timeoutInterval = self.timeoutInterval
return req
}
}
