RMQClient（RabbitMQ）獲得握手超時錯誤

Question

我使用pod RMQClient和pod install在我的項目中安裝RMQClient。然後我import <RMQClient/RMQClient.h>在ViewController。 根據官方指導，我編寫了一些代碼，但是當我運行這個項目時，我得到握手超時錯誤。

完全錯誤：

我的代碼：

- (void)viewDidLoad { 
    [super viewDidLoad]; 
    // Do any additional setup after loading the view, typically from a nib. 
    [self send]; 
    [self receive]; 
} 
- (void)send 
{ 
    RMQConnection * conn = [[RMQConnection alloc] initWithUri:@"amqps://username:password@192.168.x.x:5672" delegate:[RMQConnectionDelegateLogger new]]; 
    [conn start]; 
    id<RMQChannel>channel = [conn createChannel]; 
    RMQQueue * queue = [channel queue:@"hello"]; 
    [channel.defaultExchange publish:[@"hello world" dataUsingEncoding:NSUTF8StringEncoding] routingKey:queue.name]; 
    [conn close]; 
} 
- (void)receive 
{ 
    RMQConnection * conn = [[RMQConnection alloc] initWithUri:@"amqps://username:password@192.168.x.x:5672" delegate:[RMQConnectionDelegateLogger new]]; 
    [conn start]; 
    id<RMQChannel>channel = [conn createChannel]; 
    RMQQueue * queue = [channel queue:@"hello"]; 
    [queue subscribe:^(RMQMessage * _Nonnull message) { 
     NSLog(@"message:%@",[[NSString alloc] initWithData:message.body encoding:NSUTF8StringEncoding]); 
    }]; 
    [conn close]; 
} 

如何解決這個問題呢？如何使用這個框架？

我檢查你的代碼，它是相同的網站上的演示代碼。

從錯誤信息中可以看出，創建CFStream時出現錯誤。根據錯誤代碼-9847，也許該服務現在不工作，請先檢查服務狀態！

This tutorial assumes RabbitMQ is installed and running on localhost on standard port (5672). In case you use a different host, port or credentials, connections settings would require adjusting.
