# print

> `print`函数: 方便在调试场景下打印信息

## 函数说明

新增print函数，支持在脚本所有cel语法位置进行调用，用于插件调试用途

* 仅在命令行增加-debug的情况下打印内容，默认不打印
* print固定返回true, 便于以&&逻辑嵌入cel中
* 最大支持传入10个参数
* 每个参数将以一条日志独立打印
* `[]byte` 内容会以base64编码进行打印

## 函数原型

`print(...any) bool`

## 举例

```yaml theme={null}
expression: print(response.status) && response.status==200
```

```bash theme={null}
[INF] 24-07-18 13:35:25 poc:poc-test: [int64]  200 [gamma.go:162]
```

结合cel宏使用：

逐行打印response.headers中的每个key value对

```yaml theme={null}
expression: |
      response.headers.all(x,print(x+": "+response.headers[x])) && response.status == 200
```
