问题

以下是翻译好的部分：

"I have made a api that should get a user by their email but I get an error."
我创建了一个API，应该通过电子邮件获取用户，但是我遇到了错误。

"I have similar api that just works, I think it goes wrong when I send it to the controller."
我有一个类似的API，它正常工作，我认为问题出在将它发送到控制器时。

"The error:"

"Resolved [org.springframework.web.bind.MissingServletRequestParameterException: Required request parameter 'email' for method parameter type String is not present]"
已解决 [org.springframework.web.bind.MissingServletRequestParameterException: 方法参数类型为String的必需请求参数 'email' 不存在]

得分: 1

不确定在Vue上下文中api是什么，但我猜你需要将Authservice更改为：

getUserByEmail(email) {
    return api.get("/auth/get?email=" + email);
}

getUserByEmail(email) {
    return api.get("/auth/get?email=" + email)
  }
