• 使用的是angular-file-upload

• angular页面将图片上传到图片服务器，出现了跨域问题

//angular页面所在的域名是：http://dev.1-1dr.com
var testObj = angular.module('testApp',['angularFileUpload']);
testObj.controller("testCtr",function($scope,$upload){
    $scope.title = "测试文件上传";
        $scope.fileInfo = file;
        $upload.upload({
            //服务端接收
            url: 'http://upload.1-1dr.com/fileupload',
            //上传的同时带的参数
            data: { 'username': 'test'},
            file: file
        }).success(function (data) {
            //上传成功
            console.info(JSON.stringify(data));
        }).error(function (data, status, headers, config) {
            //上传失败
            console.log('error status: ' + status);
        });
    }
});

XMLHttpRequest cannot load http://upload.1-1dr.com/fileupload. Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://dev.1-1dr.com' is therefore not allowed access.

• 按照CORS的解决方法，服务器端响应添加了Access-Control-Allow-Origin头，但问题还是没解决。

• 想问，是不是angular在上传文件的请求中，也需要带一些参数，才能解决跨域问题？
