AngularJs 文件上传（实现Multipart/form-data 文件的上传）

<!-- 上传yml文件 -->
<div class="blackBoard" ng-show="vm.showUpop==true"></div>
<div class="updaYMLpop" ng-show="vm.showUpop==true">
    <div class="title">新建服务容器<span ng-click="vm.showUpop=false">×</span></div>
    <ul>
        <li>选择节点：<select ng-model="nodeInf" ng-options="n.addr for n in vm.nodeInf" ng-change="vm.nodeSele=nodeInf">
        </select></li>
        <li>指定路径：<input type="text" placeholder="请输入路径信息" class="ymLJ"></li>
        <li>选择文件：<a href="javascript:;" class="file">文件
        <input type="file" name="" id="" onchange="angular.element(this).scope().uploadDoc(this.files)">
        </a></li>
    </ul>
    <div class="upbtn">

代码略粗糙，标红处比较要紧。
