Ⅰ. Issue Description

如果用户输入的内容是带 + 加号的，会出现往阿里内容安全服务那边走的时候，计算签名错误，导致“漏风”没有准确拦截。

Ⅱ. Describe what happened

Ⅲ. Describe what you expected to happen

正常处理特殊符号

Ⅳ. How to reproduce it (as minimally and precisely as possible)

直接用阿里内容安全官方的 SDK 示例代码测试“AA 事件”、“AA事件”、“AA+ 事件”均成功拦截

但是通过 Higress AI 内容安全插件“AA+ 事件”无法被拦截，从日志看出现下面截图的错误

Ⅴ. Anything else we need to know?

Ⅵ. Environment:

• Higress version:
• OS :
• Others:
