我正在使用Xcode 6.1,iOS 8.1中的应用程序; 应用程序工作完全正常,直到2天,但今天我执行它时,我在Web服务中出错,错误打印在下面.

错误:错误域= NSURLErrorDomain代码= -1001"请求超时." UserInfo = 0x7c6899b0 {NSErrorFailingURLStringKey =,NSErrorFailingURLKey =,NSLocalizedDescription =请求超时.,NSUnderlyingError = 0x7c688f60"请求超时."}

我曾使用AFNetworking 2.x和以下代码片段进行网络呼叫:

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
manager.responseSerializer.acceptableContentTypes=[manager.responseSerializer.acceptableContentTypes setByAddingObject:@"text/html"];

[manager POST:<URL>
   parameters:<parameters>
      success:^(AFHTTPRequestOperation *operation, id responseObject) {

          NSLog(@"JSON: %@", responseObject);
          NSError *error = nil;
          NSDictionary *JSON = [NSJSONSerialization JSONObjectWithData:responseObject options:NSJSONReadingAllowFragments error:&error];
          if (error) {
              NSLog(@"Error serializing %@", error);
          }
          NSLog(@"Dictionary %@", JSON);
          NSLog(@"Success");
      }
      failure:^(AFHTTPRequestOperation *operation, NSError *error) {
          NSLog(@"Error: %@", error);
      }]; 
}

更新:我已经退出/重新启动了iOS …

我使用下面的代码将文件发送到服务器:

NSString *urlString = [NSString stringWithFormat:@"%@%@",[LIUtility sharedUtility].uploadConnectionURL,BR_SERVER_UPLOAD_ADDRESS_FILE];

self.request =[[NSMutableURLRequest alloc] init];
[self.request setURL:[NSURL URLWithString:urlString]];
[self.request setHTTPMethod:@"POST"];

PKMultipartInputStream *body = [[PKMultipartInputStream alloc] init];

NSString *requestString =[self getRequestStringForRange:range andExtension:fileName];
NSData *requestData = [requestString dataUsingEncoding:NSUTF8StringEncoding];

NSString *jsonLengthString = [NSString stringWithFormat:@"%04lu",(unsigned long)requestData.length];
NSData *jsonLengthData = [jsonLengthString dataUsingEncoding:NSUTF8StringEncoding];

[body addPartWithName:@"jsonLength" data:jsonLengthData];
[body addPartWithName:@"json" data:requestData];
[body addPartWithName:@"separator" string:@"\r\n"];
[body addPartWithName:@"fileData" filename:fileName stream:dataStream streamLength:streamSize];

[self.request setHTTPBodyStream:body];
[self.request setTimeoutInterval:60];
NSString *contentType = LI_CONNECTION_CONTENTTYPE;
[self.request addValue:contentType forHTTPHeaderField: @"Content-Type"];

self.connection = [[NSURLConnection alloc] initWithRequest:self.request delegate:self];
_responseData = [NSMutableData data];
[self.connection …
