当我使用这样的简单javascript请求时,我可以通过邮递员甚至通过我的应用程序发布一个基于64编码的图像:
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文件复制的简单代码上传时
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);
}
};
我得到一个跨域错误:
XMLHttpRequest无法加载"url"。跨源请求仅支持以下协议方案:http、data、chrome、chrome扩展、https、chrome资源扩展。
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。只有我或角度误差真的很令人沮丧,因为中间有这么多层。C#绝对不是那么难
好的,想明白了。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);
});
};
