element-ui中的upload組件帶token的兩種方法

方法1(默認方式)：

<el-upload
  action="http://irhfuwu.com:5566/OE/UploadFile/AttachUpload";
  multiple
  :limit="3"
  :headers="myHeaders"    //注：此處也能夠使用computed來傳動態值
  :on-success="sucH">
  <el-button size="small" type="primary">點擊上傳1</el-button>
</el-upload>

...

data: {
  myHeaders: {
      token: "324234234234324343pz9cvbg3Rw="
  }
},

方法2（不用action，改用自寫ajax方式）：

<el-upload
  action="#"
  :before-upload="beforeUpload"
  multiple
  :limit="3"
  :on-success="sucH">
  <el-button size="small" type="primary">beforeUpload方式上傳</el-button>
</el-upload>

....

beforeUpload:function (file) {
    var fd = new window.FormData();
    fd.append('key', file, 'fileName')
    axios.post("http://irhfuwu.com:5566/OE/UploadFile/AttachUpload";, fd, {
        headers: {
            token: "456436523YZgX6PXALReS5l51QwzVf0eQnYvDJJBKxG91Wpz9cvbg3Rw="
        }
    }).then(function (res) {
      console.log(res);
    });
    return false // 返回false不會自動上傳
}
