首先配置天翼云，如下操作

1、要求

在使用 OOS 之前，首先需要在 www.ctyun.cn 注册一个账号（Account）。 创建 AccessKeyId 和 AccessSecretKey。AccessKeyId 和 AccessSecretKey 是您访 问 OOS 的密钥，OOS 会通过它来验证您的资源请求，请妥善保管

2 使用方式

<!—引入本地资源-->
<script src="./oos-sdk-x.x.x.min.js"></script> 

使用 new OOS 创建 oos 对象 OOS JS-SDK 目前只支持异步请求方式，通过 callback 方式处理，对于 err 处理，非 err 显示处理结果。下图示例初始化到返回结果流程：

var client = new OOS.S3({...});
var params;
client.listObjects(params, function (err, data) {
if (err) console.log(err, err.stack); // an error occurred
else console.log(data); // successful response
});

3 CORS 配置

从浏览器中直接访问 OOS 需要开通 Bucket 的 CORS：

• 将 来源（*）设置成: *

• 将允许的方法（*）设置成: PUT, GET, POST, DELETE, HEAD

• 将允许的 Headers 设置成: *

• 将暴露的 Headers：设置成: ETag 注意：请将该条 CORS 规则设置成所有 CORS 规则的第一条

 

由于浏览器的同源策略，在浏览器里调用 JS-SDK 时, 部分功能无法实现，包括 Service 的 操作，Bucket 的新建，AccessKey 以及 SecretKey 的操作

4、options配置项

OOS options介绍

封装上传组件如下：

<template>
  <div :class="{exceed: isExceed}">
    <el-upload ref="upload" action="#" :http-request="httpRequest" :before-upload="beforeUpload"
      list-type="picture-card" :on-preview="handlePictureCardPreview" :file-list="fileList" :on-remove="handleRemove"
      v-bind="$attrs" :on-exceed="handleOnExceed" :on-success="handleOnSuccess" :on-change="onChangeFile">
