uniapp 获取appid

根据提供的引用内容，可以使用uni.login()接口来获取uniapp的appid。在uni.login()的成功回调函数中，可以通过res.code获取到用户的code值。然后可以将code值传递给后端接口，以获取openid。具体代码如下所示：

uni.login({
  provider: 'weixin',
  success: function (res) {
    let code = res.code;
    // 将code值传递给后端接口，以获取openid
    // 调用后端接口的方法可以根据实际情况进行修改
    appService.getOpenid({ code: code }).then((res) => {
      console.log(res); // 这里的res就是openid
    });
  }
});

请注意，以上代码仅为示例，具体的后端接口调用方法需要根据实际情况进行修改。
