用于发布订阅无法找到谷歌API客户端话题

我试图使用java发布 - 订阅客户端得到一个名为话题：用于发布订阅无法找到谷歌API客户端话题

@Value("projects/${pubsub.projectId}/topics/${environment}-events") 
String topic; 

Pubsub client = PubsubUtils.getClient(); 
     if (enabled) { 
      logger.info("PubSub event logging: enabled"); 
      Topic t = null; 
      try { 
       t = client.projects().topics().get(topic).execute(); 
       if (t != null) { 
        logger.info("PubSub topic {} already exists. Continuing ...", topic); 
        return client; 
       } 
      } catch (Exception ex) { 
       logger.info("Failed to get topic: {}", topic, ex); 
      } 

      // create topic 
      if (t == null) { 
       createTopic(client); 
      } 
     } else { 
      logger.info("PubSub event logging: disabled"); 
     }

不幸的是，当我跑这跟

String topic = "projects/projectid/topics/topicid";

我不断地得到回404响应：

从它的外观来看，客户端库似乎是url转义主题名称在网址和谷歌服务器失败。

有没有办法解决这个问题或者更好的方法来让谷歌API客户端不逃避主题名称。

编辑按照要求，这是完整的源代码：

@Value("projects/${pubsub.projectId}/topics/${environment}-events") 
String topic; 

Pubsub getPublisher() throws Exception { 
    Pubsub client = PubsubUtils.getClient(); 
    if (enabled) { 
     logger.info("PubSub event logging: enabled"); 
     Topic t = null; 
     try { 
      t = client.projects().topics().get(topic).execute(); 
      if (t != null) { 
       logger.info("PubSub topic {} already exists. Continuing ...", topic); 
       return client; 
      } 
     } catch (Exception ex) { 
      logger.info("Failed to get topic: {}", topic, ex); 
     } 

     // create topic 
     if (t == null) { 
      createTopic(client); 
     } 
    } else { 
     logger.info("PubSub event logging: disabled"); 
    } 
    return client; 
} 

Topic createTopic(Pubsub client) throws IOException { 
    return client.projects().topics().create(topic, new Topic().setName(topic)).execute(); 
}

您使用的是哪个版本的客户端库？ –

另外，它似乎在createTopic失败，没有得到。你可以显示createTopic的代码吗？ –

用完整的源代码更新了问题。 –

有没有在你的项目中使用的任何其他谷歌API？我刚刚解决了这个问题。我使用Google DataStore API和jar google-http-client 1.15将主题从'/'编码为'％2F'，这是不正确的。您可以排除谷歌-HTTP客户端1.15从其他谷歌的API

Maven code: 
    <exclusion> 
     <groupId>com.google.http-client</groupId> 
     <artifactId>google-http-client</artifactId> 
    </exclusion>

请使用1.20或更高版本！正确的主题如下。

<code>/v1/projects/brightcove-rna-master/topics/dev_achauhan-events</code>
