前端代码


Page({
  data: {
  },
  onLoad: function () {
    console.log('Welcome to Mini Code')
  },
  pay() {
    tt.request({
      url: "http://127.0.0.1:8080/preorder",
      success: (res) => {
        console.log(res.data)
        let order_id = res.data.data.order_id
        let order_token = res.data.data.order_token
        tt.pay({
          orderInfo: {
            order_id: order_id,
            order_token: order_token,
          },
          service: 5,
          success(res1) {
            if (res1.code == 0) {
              // 支付成功处理逻辑，只有res.code=0时，才表示支付成功
              // 但是最终状态要以商户后端结果为准

              tt.showToast({
                title: '支付成功',
              });
            }
          },
          fail(res1) {
            // 调起收银台失败处理逻辑
          },
        });
      }
    });
  }
})

使用

paramsMap := map[string]interface{}{
			"app_id":       "ttb905cfb8263a12dc01",
			"out_order_no": "noncestr" + timestamp,
			"total_amount": 1,
			"subject":      "抖音商品",
			"body":         "抖音商品",
			"valid_time":   300,
			"notify_url":   "https://app.mujuapi.cn/api/pay/notify",
		}

替换 app_id notify_url为自己的
