如何使用 axios (put) 更新变量？我的函数不更新模板

Question

我希望我的变量（行：{{user.email}}在我发送表单时更新。

我在我的页面上创建了一个表单，以便用户可以更新他们的数据。在后端一切正常，我用 Postman 进行了模拟。

在前端，我使用 vuejs 和 axios。我创建了一个带有输入和按钮的表单来提交我的更新请求。新邮件已在我的数据库中注册（mysql sequelize），但是当我刷新页面时没有任何变化。除非我注销，否则令牌不会更新。我认为问题是令牌仍然包含用户切换之前的旧邮件，因此页面上没有跟随信息。

如何进行动态刷新以便更新我的 user.email 变量？

在 put 响应中，您应该更新本地状态。

this.user.email = response.data.email
