常用方法

uniapp base64

//base64加密
export const encrypt = (str) => {

获取导航栏等信息

export const getEquipmentInformation = () => {

      if (e.platform === "android") {
        this.$store.commit("SET_SYSTEM_IOSANDROID", false);
        customBar = e.statusBarHeight + 50;
      }
      // #endif
      // #ifdef MP-WEIXIN
      statusBar = e.statusBarHeight;
      const custom = wx.getMenuButtonBoundingClientRect();
      customBar = custom.bottom + custom.top - e.statusBarHeight;
      navbar = (custom.top - e.statusBarHeight) * 2 + custom.height;
      // #endif
      // #ifdef MP-ALIPAY
      statusBar = e.statusBarHeight;
      customBar = e.statusBarHeight + e.titleBarHeight;
      // #endif
      // #ifdef APP-PLUS
      console.log("app-plus", e);
      statusBar = e.statusBarHeight;
      customBar = e.statusBarHeight + 45;
      // #endif
      // #ifdef H5
      statusBar = 0;
      customBar = e.statusBarHeight + 45;
      // #endif
    },
  });

数字转成汉字

/**
 * @params num === 要转换的数字
 * @return 汉字

获取年月日

export const transitionTime = (timestamp) => {
  let date = new Date(parseInt(timestamp));
  let Year = date.getFullYear();
  let Moth = date.getMonth() + 1 < 10 ? "0" + (date.getMonth() + 1): date.getMonth() + 1;

  let Sechond = date.getSeconds() < 10 ? "0" + date.getSeconds() : date.getSeconds();
  let GMT = Year + "-" + Moth + "-" + Day + "   " + Hour + ":" + Minute + ":" + Sechond;
  return GMT; // 2022-09-07 15:56:07
};

字符串转时间戳

/**
   * 字符串转时间戳
   * @param {Object} expiresTime
   */
export const strTotime(expiresTime){

    expires_time = expires_time.replace(/-/g, '/');
    return Math.round(new Date(expires_time).getTime() / 1000);
  }

获取当前时间戳

export const time() {
   return Math.round(new Date() / 1000);
  }
