用帝国cms系统怎么做网站详情页页面页面

使用网页配置订阅

1. 创建主题>使用标准>自定义名称>其他默认 点击创建即可

2. 创建订阅
   

3. 订阅策略配置（不配置，会推送给多个人，除非你每个都创建主题）
   注意： 可以你可以随便写，后面的值只能是对象，不然会报错

4. 创建好订阅，会给你配置的链接推送请求（post请求，text/plain 格式）

body参数如下：

{Type: 'SubscriptionConfirmation',MessageId: 'e67f028f-3392-4f8e-871e-d5f6c1de7256',Token:'***',TopicArn: 'arn:aws:sns:us-west-1:180656209983:klover-test-topic',Message:'***',SubscribeURL:'https://sns.us-west-1.amazonaws.com/?***',SignatureVersion: '1',Signature:'***',SigningCertURL: '***',
};

5. 确认订阅
   （1）使用浏览器直接访问 SubscribeURL（第四步返回的url）
   （2）使用页面订阅 在下面输入框输入 SubscribeURL（第四步返回的url）

6. 如果没有接收到确认订阅 可以选择再次发送

安装java jar包

        <dependency><groupId>software.amazon.awssdk</groupId><artifactId>sns</artifactId><version>2.16.60</version></dependency>

使用

        // 推送String message = "{\"test\":1,\"name\":\"klover\"}";Sns.pubTopic(message); // 使用代码订阅Sns.subscribe("https://www.xxx.cn/api", "https");
