ng-file-upload 跨域错误

Question

当我使用简单的 javascript 请求时，我可以通过 postman 甚至通过我的应用程序 post base 64 编码图像：

var data=       "userPhoto=data%3Aimage%2Fjpeg%3Bbase64%2C%2F9j%2F4AAQSkZJRgABAQEAS ................(image data) Rd1bbfc2B%2FdDXGWxWHtA2N6NrL%2BLNf6wIa92a5m5v2s0c7tObhgdJMdV6Rm4mt7YkqukTMsv2vVsgl5j73tQasFOHYMP3nqf%2F%2FZ";
var xhr = new XMLHttpRequest();
xhr.withCredentials = true;
xhr.addEventListener("readystatechange", function () {
  if (this.readyState === 4) {
  console.log(this.responseText);
 }
});

xhr.open("POST", "http://localhost:8000/test2");
xhr.setRequestHeader("cache-control", "no-cache");
xhr.setRequestHeader("postman-token", "b98cbdf1-8918-b8fb-6b50- a626c301cffc");
xhr.setRequestHeader("content-type", "application/x-www-form-urlencoded");
xhr.send(data);

但是当我使用从ng-file-upload

复制的简单代码时

HTML:

  <div class="button" ngf-select ng-model="file" name="file" ngf-pattern="'image/*'" ngf-accept="'image/*'" ngf-max-size="20MB" ngf-min-height="100" ngf-resize="{width: 100, height: 100}">Select</div>

脚本：

var app = angular.module('fileUpload', ['ngFileUpload']);
app.controller('MyCtrl', ['$scope', 'Upload', function ($scope, Upload) {
// upload later on form submit or something similar
$scope.submit = function() {
  if ($scope.form.file.$valid && $scope.file) {
    $scope.upload($scope.file);
  }
};

我遇到跨域错误：

XMLHttpRequest cannot load 'url'. Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https, chrome-extension-resource.

基本上我已经尝试了所有不同的组合，从实际场景到简化版本再到网站上最基本的用例。这只是我或 angular 错误真的很令人沮丧，因为中间有很多层。 C# 绝对没那么难

好的，明白了。在上传功能中，我使用了整个 URL http://localhost:8000/test1，但我应该只使用 /test1

$scope.upload = function (file) {
    Upload.upload({
        url: '/test1',
        data: {'userPhoto':file}
    }).then(function (resp) {
        console.log('Success ' + resp.config.data.file.name + 'uploaded.    Response: ' + resp.data);
    }, function (resp) {
        console.log('Error status: ' + resp.status);
    });
};
