wx.addcard段代码

let cardExt={

        timestamp:timestamp,

        nonce_str:nonce_str,

        signature:signature,

        api_ticket:e.data.ticket

      }

      console.log(JSON.stringify(cardExt))

      wx.addCard({

        cardList: [{

          cardId: cardId,

          cardExt: JSON.stringify(cardExt)

        }],

        success: function (res) {

          var cardList = res.cardList; // 添加的卡券列表信息

          console.log(123)

          console.log(cardList)

                   },

        fail(res){

          console.log(res)

        },

        complete(res){

          console.log(res)

          console.log(123)

        }

      })

不论success fail complete 都不报返回

上边提示签名错误 可是签名跟测试的是一致的 请问怎么解决呀
