我一直在努力在服务器上上传图片。我在前端使用ngFileUpload。但我总是得到
“对预检请求的响应未通过访问控制检查:请求的资源上没有'Access-Control-Allow-Origin'标头”
文件上传的角色代码:
var uploadFile = function (file) {
if (file) {
if (!file.$error) {
Upload.upload({
url: baseUrl+'upload',
file: file
}).progress(function (evt) {
var progressPercentage = parseInt(100.0 * evt.loaded / evt.total);
//console.log(evt.total);
}).success(function (data, status, headers, config) {
$timeout(function() {
console.log(data);
console.log(status);
if(status==200)
{
logo_path = data.logo_path;
}
});
});
}
}
};
在Laravel上我已经像这样配置了CORS:
public function handle($request, Closure $next)
{
header("Access-Control-Allow-Origin: http://localhost:8001/");
// ALLOW OPTIONS METHOD
$headers = [
'Access-Control-Allow-Methods'=> 'POST, GET, OPTIONS, PUT, DELETE',
'Access-Control-Allow-Headers'=> 'Content-Type, X-Auth-Token, Origin'
];
if($request->getMethod() == "OPTIONS") {
// The client-side application can set only headers allowed in Access-Control-Allow-Headers
return Response::make('OK', 200, $headers);
}
$response = $next($request);
foreach($headers as $key => $value)
$response->header($key, $value);
return $response;
}
普通跨域POST请求正常。即$ http.post()。我在角度上尝试了许多不同的标题变体但没有帮助。此外,OPTIONS请求返回200 OK,但仍显示预检响应失败消息。任何人都可以帮我解决这个问题的进一步调试吗?
答案 0 :(得分:8)
尝试添加:
header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Headers: Origin, Content-Type');
header('Access-Control-Allow-Methods: POST, GET, OPTIONS, PUT, DELETE');
在bootstrap / app.php中 您也可以在此处插入访问控制所需的任何其他标头。
