How to send form data to php file using vue-resource?

Question

Vue.js

I have the following Vue.js code (vue-resource plugin included), what should I write in the mail.php file so that the file accepts the data entered in the form?

<template>
  <div id="app">
    <div class="editor">
      <form @submit.prevent="savePost()">
        <input type="text" placeholder="Заголовок" v-model="post.a">
        <textarea placeholder="Текст" v-model="post.b"></textarea>
        <button>Опубликовать</button>
      </form>
    </div>
  </div>
</template>

<script>
export default {
  name: 'App',
  data () {
    return {
      endpoint: 'mail.php',
      posts: [],
      post: {}
    }
  },
  computed: {
     resource() {
            return this.$resource('mail.php')
        }
  },
     methods: {
        savePost() {

            this.resource.save(this.post)

        },
        getSinglePost() {

            this.resource.get().then(function(response) {

                this.post = response.data

            })

        }
    }
}
</script>

VUE-resource is no longer relevant. Even developers advise using axios.
You must send a POST request to a PHP file with JS. In a PHP file, you have to accept $_POST['value'] data and process it already.
