我以前从未遇到过这个问题,但有时当我从服务器请求数据时(大约 10% 的时间),我从未收到响应(甚至没有标题!)并且请求超时。我使用networkQueue,它的设置是这样的

    //when initializing
    networkQueue = [[ASINetworkQueue queue] retain];
    networkQueue.maxConcurrentOperationCount = 5;
    networkQueue.delegate = self;
    networkQueue.requestDidReceiveResponseHeadersSelector = @selector(request:DidReceiveHeaders:);
    networkQueue.requestDidFinishSelector = @selector(NetworkQueueRouter:);
    networkQueue.requestDidFailSelector = @selector(requestDidFail:);

我用这个方法初始化请求

-(void)sendRequest:(NSURL *)url withParams:(NSDictionary *)params andUserInfo:(NSDictionary *)info{
    ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
    request.delegate = self;
    NSString *jsonString = [params yajl_JSONString];
    [request setPostValue:jsonString forKey:@"json"];
    request.timeOutSeconds = 30;
    if (info != nil)    request.userInfo = info;
    [networkQueue addOperation:request];
    [networkQueue go];
}

我只有在使用 iPhone 或 iPhone Simulator 时才会遇到这个问题。有时,当请求一直持续时,我会用相同的请求检查我的浏览器,当 iPhone 仍在请求时,我会立即从浏览器中获得响应。

有谁之前经历过这个吗?
