[英]No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8100' is therefore not allowed access
server.js我已经声明了权限
app.use(function(req, res, next) {
res.header("Access-Control-Allow-Origin", "*");
res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
next();
});
app.js
angular.module('app', ['ionic', 'ui.router'])
.config(('$urlRouterProvider', '$stateProvider', function($urlRouterProvider,$stateProvider){
$urlRouterProvider.otherwise('/');
$stateProvider
.state('view',{
url:'/',
templateUrl:'js/components/view/view.html',
controller:'viewCtrl'
})
}))
view.js
.controller('viewCtrl',['$scope','$state','$http',function($scope,$state,$http)
{
$scope.pics=[];
$http.get('http://localhost:8080/getNewPhoto').then(function(response){
$scope.pics=response.data;
},function(err)
{
console.error("There's an error"+err);
})
}])
请帮助我解决这个问题我已经尝试了所有可能的解决方案,但问题仍然存在
只需使用快递的cors模块 ,您就可以了:
var express = require('express')
var cors = require('cors')
var app = express()
app.use(cors())
您必须添加一个重要的标题。 将该行添加到服务器脚本:
res.header('Access-Control-Allow-Methods','POST, GET, OPTIONS, PUT');
