419（未知状态）使用AXIOS和Laravel的POST请求出错

Question

Sorry to bother all of you. I have searched many times. I tried the probable solution too. I have set the csrf_token using meta tag

  <meta name="csrf-token" content="{{ csrf_token() }}">

My POST request is like the below

tryAuth () {

  if (this.$refs.form.validate()) {

    let _this = this

    axios.post('/trylogin',_this.loginInfo, {
      headers: {
        //'X-CSRF-TOKEN': document.querySelector('meta[name="csrf-token"]').getAttribute('content')
      },
      //withCredentials: true
    }).then(function(response){

      console.log(response.data)

    })
    .catch(function(error){

    })

  }

I have tried both using with and without the headers. Sometimes the response is okay but sometimes it shows 419 error response.

I am using Laravel 5.5 and AXIOS latest version. Any help would be appreciated. I have found some solution and tried but didn't work for me.

Thanks :)
