NSMutableURLRequest超时时间间隔不考虑POST请求(NSMutableURLReq

我有以下问题。 上的NSMutableURLRequest使用HTTP方法POST超时间隔设定为连接被忽略。 如果网络连接有问题（错误的代理，坏DNS）约2-4分钟后URL请求失败，但是不能与NSLocalizedDescription = "timed out";

NSUnderlyingError = Error Domain=kCFErrorDomainCFNetwork Code=-1001 UserInfo=0x139580 "The request timed out.

如果http使用的方法是GET ，它工作正常。 连接是async过https 。

    NSURL *url = [NSURL URLWithString:urlString];
    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];    

    [request setTimeoutInterval:10];

    //Set the request method to post
    [request setHTTPMethod:@"POST"];

    if (body != nil) {
        [request setHTTPBody:body];
    }

    // Add general parameters to the request
    if (authorization){
        [request addValue: authorization forHTTPHeaderField:@"Authorization"];
    }
    [request addValue: WS_HOST forHTTPHeaderField:@"Host"];
    [request addValue:@"text/xml" forHTTPHeaderField:@"Content-Type"];

    [[NSURLCache sharedURLCache] setDiskCapacity:0];

    [self addToQueueRequest:request withDelegate:delegate];

根据对苹果开发者论坛一个帖子，对POST最小超时间隔为240秒。 比任何较短的超时间隔将被忽略。

如果您需要更短的超时时间间隔，使用异步请求与定时器一起，并呼吁根据需要在NSURLConnection的取消。

iOS 6中已经修复了这个问题。

NSMutableURLRequest *request = [NSMutableURLRequest 
                                requestWithURL:[NSURL URLWithString:url] 
cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:20];

[request setHTTPMethod:method];
[request setHTTPBody:requestBody];
NSLog(@"%f", [request timeoutInterval]); 
//20.0 in iOS 6
//240.0 in iOS 4.3, 5.0, 5.1

修正了克莱钱伯斯的建议：用自定义定时器的子类中增加了一个计时器NSURLConnection

if (needsSeparateTimeout){

    SEL sel = @selector(customCancel);

    NSMethodSignature* sig = [self methodSignatureForSelector:sel];

    NSInvocation* invocation = [NSInvocation invocationWithMethodSignature:sig];

    [invocation setTarget:self];

    [invocation setSelector:sel];

    NSTimer *timer = [NSTimer timerWithTimeInterval:WS_REQUEST_TIMEOUT_INTERVAL invocation:invocation repeats:NO];

    [[NSRunLoop mainRunLoop] addTimer:timer forMode:NSDefaultRunLoopMode];

}

在自定义取消方法的连接被取消

[super cancel];

它看起来像这里所描述的问题仍然面临的iOS 7.1（或重新出现）。 幸好它看起来像设置timeoutIntervalForResource上的配置属性NSURLSession可以解决这个问题。

根据@XiOS观察这个工程的超时比（约）2分钟以下。

如果你的意思是如何处理超时错误，我想没有人回答这个问题还没有

让我写我的代码PICE解释说点

// replace "arg" with your argument you want send to your site 
 NSString * param = [NSString stringWithFormat:@"arg"];

    NSData *Postdata = [param dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];
    NSString *postLength = [NSString stringWithFormat:@"%lu",(unsigned long)[Postdata length]];
    NSMutableURLRequest *request = [[NSMutableURLRequest alloc]init];
// replace "yoursite" with url of site you want post to 
    [request setURL:[NSURL URLWithString:[NSString stringWithFormat:@"http//yoursite"]]];
// set what ever time you want in seconds 120 mean 2 min , 240 mean 4 min 
    [request setTimeoutInterval:120];
    [request setHTTPMethod:@"POST"];
    [request setValue:postLength forHTTPHeaderField:@"Content-Length"];
    [request setValue:@"application/x-www-form-urlencoded"  forHTTPHeaderField:@"Current-Type"];

    [request setHTTPBody:Postdata];
    NSURLConnection * connection = [[NSURLConnection alloc]initWithRequest:request delegate:self];

// if request time out without response from server error will occurred 

-(void) connection:(NSURLConnection * ) connection didFailWithError:(NSError *)error {    
    if (error.code == NSURLErrorTimedOut) 
        // handle error as you want 
        NSLog(@"Request time out , Please try again later");
}

我希望这帮助任何一个询问如何处理超时错误
