使用包含Vue.js的Laravel 5.3全新安装并配置开箱即用:
this.$http.get(url)
返回错误:
TypeError:此$ 1. $ http未定义
用Vue.http.get(url)...
替换它会产生请求,但无法发送预检选项:
在CORS预检频道的CORS标题“Access-Control-Allow-Headers”中丢失标记'x-csrf-token'
app.js:
require('./bootstrap');
Vue.http.headers.common['X-CSRF-TOKEN'] = document.querySelector('#token').getAttribute('content');
let app = new Vue({
el: '#app',
mounted: () => {
navigator.geolocation.getCurrentPosition((position) => {
app.getZip(position);
});
},
methods: {
getZip: (position) => {
let lat = position.coords.latitude;
let long = position.coords.longitude;
let url = encodeURI(`https://maps.googleapis.com/maps/api/geocode/json?latlng=${lat},${long}&sensor=false`);
Vue.http.get(url).then((response) => {
let zip = response.body.results[0].address_components[5].short_name;
console.log(zip);
});
},
},
});
bootstrap.js:
window._ = require('lodash');
window.$ = window.jQuery = require('jquery');
require('bootstrap-sass');
window.Vue = require('vue');
require('vue-resource');
Vue.http.interceptors.push((request, next) => {
request.headers.set('X-CSRF-TOKEN', Laravel.csrfToken);
next();
});
相关的app.blade.php:
<meta id="token" name="csrf-token" content="{{ csrf_token() }}">
<script>
window.Laravel = <?php echo json_encode([
'csrfToken' => csrf_token(),
]); ?>
</script>
<script src="/js/app.js"></script>
gulpfile.js:
const elixir = require('laravel-elixir');
require('laravel-elixir-vue-2');
elixir(mix => {
mix.sass('app.scss')
.webpack('app.js');
});
如果我包含<script src="https://cdnjs.cloudflare.com/ajax/libs/vue-resource/1.0.3/vue-resource.min.js"></script>
,它将成功地同时发出请求:
Vue.http.get(url)
this.$http.get(url)
为什么这不适用于node_module?
require('vue-resource')
答案 0 :(得分:-1)
因为你正在使用require。如果你使用require,你需要一些像browserify或webpack这样的库,它允许我们使用node.js样式的模块进行编译,以便在浏览器中使用。
