除非我重新登录，否则不会显示对用户的更改
除非我重新登录，否则不会显示对用户的更改
提问于 2019-06-11 02:58:36
我有一个用户网页，有不同的信息，如用户名，个人资料，个人资料图片等。
我已经创建了不同的按钮，可以让我更改信息并将更改保存到数据库中，但在更改个人资料图片后，例如，即使我重新加载页面，也没有显示任何内容，但如果重新登录到该用户帐户，更改最终会出现，这是不方便的实时。
我的html代码：

如下所示更改您的editINFO方法，以便在编辑完信息后更新本地存储，假设您返回了在登录时获得的更新后的用户信息实例。：
editINFO() {
this.service.editUser(this.infoForm.value, this.loginUser.token).subscribe(res => {
localStorage.setItem('currentUser', res ); // Provided you are returning the user info
on update.
location.reload();
});
