#pragma mark - 使用ASIHTTPRequest，block请求方式
- (void) requestUseASIHTTP2{
    __block ASIHTTPRequest *blockRequest = [ASIHTTPRequest requestWithURL:[self generateURL]];
    blockRequest.requestMethod = @"POST";

    }];
    [blockRequest setFailedBlock:^{
        NSError *error = [blockRequest error];
        NSLog(@"Error:%@",error.userInfo);
    }];
    [blockRequest startAsynchronous];//发送异步请求
