tls的key_share和浏览器的不太一样

[tocha688]

这是chrome浏览器的

这是火狐浏览器的

下面是模拟请求的，ja3和h2都是设置的浏览器的

        ]
      }

有没有办法设置成一样的字段

[tocha688]

加了一段修复代码

func ja3_extension[V1 utls.TLSExtension](ja3s ja3.Ja3Spec) (V1, int) {
    for i, k := range ja3s.Extensions {
        // 尝试将k断言为指向V1类型的指针
        if n, isok := k.(V1); isok {
            return n, i
        }
    }
    var zero V1
    return zero, -1
}

// ja3 修补程序
func ja3_repair(p *RestyRequest, ja3s ja3.Ja3Spec) ja3.Ja3Spec {
    if p.IsChrome() {
        //修补 KeyShare
        tks, index := ja3_extension[*utls.KeyShareExtension](ja3s)
        if index != -1 {
            tks.KeyShares = []utls.KeyShare{
                {Group: utls.CurveID(utls.GREASE_PLACEHOLDER), Data: []byte{0}},

            }
        }
    }
    return ja3s
