标签: javascript angularjs cross-domain ng-file-upload

当我使用简单的javascript请求时,我可以通过邮递员甚至通过我的应用程序发布基本64位编码图像:

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);
  }
}; 

我收到了跨域错误:

  

XMLHttpRequest无法加载“url”。交叉源请求仅支持协议方案:http,数据,chrome,chrome-extension,https,chrome-extension-resource。

基本上我已经尝试了从实际场景到简化版本到网站上最基本用例的所有不同组合。它只是我或角度误差真的令人沮丧,因为它们之间有这么多层。 C#绝对不是那么难

好的想通了。在上传功能中,我使用的是整个网址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);
    });
};
