调用接口之后发现返回只有openid，是不是要这样理解，只有用户在之前 统一账户下的其他小程序~公众号授权之后，新的小程序公众号才会通过code2Session返回unionid呢？

各位前辈好，我个人理解的navigateTo的成功后回调应该是先运行回调，再跳转页面，在真机使用中（开发工具正常）发生了navigateTo跳转的页面Onload先与组件的success回调触发 我本是想跳转成功会改变全局变量，跳转的页面在onload里面再使用这个全局变量的 [图片] [图片] [图片]

navigateTo 在真机测试中 success回调函数会慢于所跳转的页面的onload触发 这是为啥呢 要怎么避免呢
