                res.data
              )}`;
              console.log(authUrl);
              if (uni.getSystemInfoSync().platform == "ios") {
                authUrl = `alipay://platformapi/startapp?appId=20000067&url=${encodeURIComponent(
                  res.data
                )}`;
              }
              plus.runtime.openURL(authUrl, function (res) {
                uni.showToast({
                  icon: "none",
                  title: "请安装支付宝之后再进行支付！",
                });
              });
