问题描述

e.g. (?<age>\\d+)?

当 age 被标记为为可选的 name group 时，无法通过 @FilterValue 获取除去 String 以外其他类型。

复现方式

测试一

    @Listener
    @Filter("^test_1(\\s+(?<page>\\d+))?")
    suspend fun OneBotNormalGroupMessageEvent.test1(
        @FilterValue("page", false) page: Int = 1
    ) {
        println("[TEST-1] plain_text->'${messageContent.plainText}' ,page->$page")
    }

测试一：输入与输出

输入test_1 1

[TEST-1] plain_text->'test_1 1' ,page->1

输入test_1

java.lang.IllegalArgumentException: java.lang.NullPointerException: Cannot invoke "java.lang.Number.intValue()" because the return value of "sun.invoke.util.ValueConversions.primitiveConversion(sun.invoke.util.Wrapper, Object, boolean)" is null

测试二

    @Listener
    @Filter("^test_2(\\s+(?<page>\\d+))?")
    suspend fun OneBotNormalGroupMessageEvent.test2(
        @FilterValue("page") page: String?
    ) {
        println("[TEST-2] plain_text->'${messageContent.plainText}' ,page->$page")
    }

测试二：输入与输出

输入test_2 1

[TEST-2] plain_text->'test_2 1' ,page->1

输入test_2

love.forte.simbot.quantcat.common.binder.BindException: love.forte.simbot.quantcat.common.binder.BindException: Nothing binder success for listener KFunctionEventListener(caller=fun <packgae_name>.TestListeners.(love.forte.simbot.component.onebot.v11.core.event.message.OneBotNormalGroupMessageEvent.)test2(kotlin.String?): kotlin.Unit, attributes={Attribute(name=$$RAW_LISTEN_TARGET$)=class love.forte.simbot.component.onebot.v11.core.event.message.OneBotNormalGroupMessageEvent, Attribute(name=$$RAW_FUNCTION$)=fun <packgae_name>.TestListeners

/**
 * 指定一个参数，此参数为通过 [love.forte.simbot.quantcat.annotations.Filter]
 * 解析而得到的动态参数提取器中的内容。
 *
 * 参数提取格式基于正则匹配模式，参考 [Filter.value] 中的相关说明。
 *
 * @param value 所需动态参数的key。
 * @param required 对于参数绑定器来讲其是否为必须的。
 *  如果不是必须的，则在无法获取参数后传递null作为结果，否则将会抛出异常并交由后续绑定器处理。
 */

“如果不是必须的，则在无法获取参数后传递null作为结果”，也就是说在无法获取时是默认返回空值？

测试三(正常运行)

    @Listener
    @Filter("^test_3(\\s+(?<page>\\d+))?")
    suspend fun OneBotNormalGroupMessageEvent.test3(
        @FilterValue("page") page: String? = null
    ) {
        println("[TEST-3] plain_text->'${messageContent.plainText}' ,page->$page")
    }

测试三：输入与输出

输入 test-3 ，输出 [TEST-3] plain_text->'test_3' ,page->null
输入 test_3 1 , 输出 [TEST-3] plain_text->'test_3 1' ,page->1

“如果不是必须的，则在无法获取参数后传递null作为结果”

如此所述，当 FilterValue 取不到值且 required = false 时，向下传递 null 是预期内的行为，但是当参数不可为 null、且存在默认值时，理应使用默认值，这应该是下游参数绑定器的缺陷。
