项目中嵌入Cognos，解决多值打开报表

cognos多个值URL传入

问题：Cognos报表有三个以上提示页面，想放在一个页面实现？

解决方案：

方案一：用get打开页面，在src中写入Congo是URL地址，局限性当多个值传入的时候长度会受到限制

方案二：用post打开页面，首先要明确Cognos多值是怎么传值的

p_VAR_CODE:<selectChoices><selectOption useValue="90552" displayValue="90552"/><selectOption useValue="90560" displayValue="90560"/><selectOption useValue="90561" displayValue="90561"/></selectChoices>
p_VAR_CODE_END:<selectChoices><selectOption useValue="90552,90560,90561," displayValue="90552,90560,90561,"/></selectChoices>

放到Java项目中
