我是Laravel和Lumen框架的新手。我正在使用流明做我的第一個項目。我想創建一個API從角預檢反應無效（重定向）錯誤
這裏打電話是我角代碼：
app.controller('ListCtrl', ['$scope', '$http', '$location', '$window', function($scope, $http, $location, $window) {
$scope.data = {};
$scope.getdata = function() {
$scope.datas = [];
$headers = {
'Access-Control-Allow-Origin' : '*',
'Access-Control-Allow-Methods' : 'POST, GET, OPTIONS, PUT',
'Content-Type': 'application/json',
'Accept': 'application/json'
};
$http({
url: "http://localhost/service/public/getdata/",
method: "GET",
params: {'place':$scope.data.place,'pincode':$scope.data.pincode},
headers: $headers
})
.success(function(data,status,headers,config) {
$scope.datas=JSON.stringify(data);
console.log($scope.datas);
$scope.navig('/show.html');
})
.error(function(){
alert("failed");
});
};
$scope.navig = function(url) {
$window.location.href = url;
};
}]);
，這裏是我的流明route.php：
<?php
header("Access-Control-Allow-Origin: *");
header("Access-Control-Allow-Headers: Content-Type");
$app->get('/', function() use ($app) {
return $app->version();
});
$app->get('getdata','App\Http\Controllers\[email protected]');
這裏是PlaceController.php
<?php
namespace App\Http\Controllers;
use App\Places;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
class PlaceController extends Controller
{
public function __construct()
{
header("Access-Control-Allow-Origin: *");
header("Access-Control-Allow-Headers: Content-Type");
//header("Access-Control-Allow-Origin: http://localhost:8100");
}
public function index()
{
$places = Place::all();
return response()->json($places);
}
}
但它顯示「XMLHttpRequest無法加載http://localhost/service/public/getdata/?place=sdfs。預檢響應無效在執行console.log（重定向）」的錯誤。
我用Google搜索了兩天，但不能找到一個解決方案。
請幫
