redirect after axios response with vue

Question

Ok, so i have the following method. Basically I am calling an API backend, posting username and password, and if those pass, in the response, the server sends me a 200 status. What I want to do, is in the response, after I get the status, run an if/else, so if the status is 200, redirect, else display an error message. every time i try to use 'this.$router.push('/any route here')',

I get an error: 'homepage.vue?3ec6:72 Uncaught (in promise) TypeError: Cannot read property '$router' of undefined'.

但是，如果我在axios调用之外的方法顶部使用相同的路由，则可以正常工作。

那我在这里想念什么？

                hero_login: function(event){
                  event.preventDefault();

                  axios.post('API call here', 
                    { 
                      service:'client',
                      user: this.user_email,
                      password: this.user_password,
                      json:true
                    })
                    .then(function(response){
                       const status = 
                         JSON.parse(response.data.response.status);
                         console.log(status);
                     })
                   }

您必须定义this外部axios方法，因为this内部axios指向axios对象，而不是vue组件：

hero_login: function(event) {
  let self = this;

  event.preventDefault();

  axios.post('API call here', 
    { 
      service:'client',
      user: this.user_email,
      password: this.user_password,
      json:true
    })
    .then(function(response){
      const status = 
        JSON.parse(response.data.response.status);

      //redirect logic
      if (status == '200') {
       self.$router.push('/any route here');
      }
    })
  }
}
