我已经使用Node/Express创建了一个小API,并试图使用Angularjs拉数据,但由于我的html页面在localhost:8888和节点API在端口3000上监听下运行,我得到了No 'Access-Control-Allow-Origin'。我尝试使用node-http-proxy和Vhosts Apache,但没有太多成功,请参阅下面的完整错误和代码。
XMLHttpRequest无法加载localhost:3000。被请求的资源上没有'Access-Control-Allow-Origin'标头。因此,不允许访问Origin 'localhost:8888'。”
// Api Using Node/Express
var express = require('express');
var app = express();
var contractors = [
{
"id": "1",
"name": "Joe Blogg",
"Weeks": 3,
"Photo": "1.png"
}
];
app.use(express.bodyParser());
app.get('/', function(req, res) {
res.json(contractors);
});
app.listen(process.env.PORT || 3000);
console.log('Server is running on Port 3000')
角码
angular.module('contractorsApp', [])
.controller('ContractorsCtrl', function($scope, $http,$routeParams) {
$http.get('localhost:3000').then(function(response) {
var data = response.data;
$scope.contractors = data;
})
HTML
<body ng-app="contractorsApp">
<div ng-controller="ContractorsCtrl">
<ul>
<li ng-repeat="person in contractors">{{person.name}}</li>
</ul>
</div>
</body>
