日常记录

使用到了apex_json方式接收

、、、1
首先，接口通过body传递过来，成功接收到， 数据格式为 JSON_OBJECT_T
l_json := JSON_OBJECT_T.parse(:body);  
这里我用参数接收到 
然后 里面是包含了 "data"
我用 继续接收到这个
l_data            := l_json.get_object('data');、、、2
但是有个问题，如果是使用系统原始的 get_array('persons')  之类的，始终是报错 
我只能将代码转成clob格式存放到系统的参数中
V_JSON_DATA := l_data.To_Clob;、、、3apex_json.parse(V_JSON_DATA);
apex_json.parse函数来解析JSON字符串使用 apex_json.parse(V_JSON_DATA); 将 CLOB 类型的 JSON 数据解析为 APEX 的 JSON 对象。
然后，尝试使用 apex_json.get_varchar2 函数来访问解析后的 JSON 数据。
apex_json.get_varchar2 函数是线程安全的，这意味着同一时间的多个请求不会互相影响。
每个 APEX 应用程序实例（即每个用户会话）都有自己的内存空间，
因此一个会话中的 apex_json.get_varchar2 调用不会影响另一个会话中的调用。
