ArticleContentController获取逛的详情内容

方法：getArticleContent() 请求参数

| 参数名称 | 参数类型 |  可否为空 | 示例 | 默认值 | 备注 | 
|:-------| -----:|-----:|-----:|-----:|----:| 
|article_id|string|否|5|0|文章id|
|client_type|string|否|h5|h5|客户端类型|

<table>
   <tr><th>参数名称</th><th>参数类型</th><th>可否为空</th><th>示例</th><th>默认值</th><th>备注</th></tr>
   <tr><td>article\_id</td><td>string</td><td>否</td><td>5</td><td>0</td><td>文章id</td></tr>
   <tr><td>client\_type</td><td>string</td><td>否</td><td>h5</td><td>h5</td><td>客户端类型</td></tr>
</table>

实现逻辑：

1、ArticleContentController.getArticleContent()方法中调用sns.guang.getArticleContent服务；

2、对参数article_id文章id是否为空或是否小于0进行验证，若为空则抛出文章id不能为空的异常或文章id错误异常；对参数client_type进行是否为空验证，若为空则设为默认值"h5";

3、根据article_id查询数据库表article_block获取该文章id对应的blocks信息，包括详情内容信息和内容键值等信息;

4、对blocks对象进行转换，返回封装的ArticleContentRspBO对象；

示例 请求：http://localhost:8080/gateway/guang/service/*/article/getArticleContent?article_id=5&client_type=h5&debug=XYZ

返回：
