Vue上传阿里云OSS(STS方式)

一、准备工作

1. 开通阿里云OSS服务，从控制台上获取AccessKeyId和AccessKeySecret。

2. 创建Bucket，并登录OSS控制台

3. 配置Bucket (很重要)

*  将allowed origins（来源）设置成 \*
 *  将allowed methods（允许methods）设置成 PUT, GET, POST, DELETE, HEAD
 *  将allowed headers（允许headers）设置成 \*
 *  将expose headers（暴露headers）设置成 ETag   （这里需要换行）  x-oss-request-id

可参考阿里官方文档：[https://help.aliyun.com/docum...][https_help.aliyun.com_docum...]

二、引入ali-oss

有两种方式：

1. 在HTML文件的<head>中包含如下标签：

2. 项目中安装ali-oss

npm install ali-oss --save

可参考阿里官方文档：[https://github.com/ali-sdk/al...][https_github.com_ali-sdk_al...]

这里使用第二种。

三、使用OSS

关于直传，阿里官方给了三种方案：

1.  客户端 JavaScript 签名后直传；
2.  客户端申请服务端签名，然后打包上传；
3.  客户端申请服务端签名，打包上传OSS后回调服务端。

这里使用第一种。

vue中使用步骤：

1.  在src目录中创建utils文件夹
2.  utils文件夹中创建Client.js
3.  在组件中创建testUpload.vue文件

//Client.js 
    const OSS = require('ali-oss');
    
    export default function Client(data) {
        //后端提供数据
        return new OSS({
            region: data.region,  //oss-cn-beijing-internal.aliyuncs.com
            accessKeyId: data.accessKeyId,
            accessKeySecret: data.accessKeySecret,
            stsToken: data.stsToken,
            bucket: data.bucket
        })
    }

//testUpload.vue 
    <template>
        
        <div>
            <el-upload
                    class="upload-demo"
                    ref="upload"
                    drag
                    :before-upload="beforeUpload"
                    :on-success="handleSuccess"
                    :http-request="handleHttpRequest"
                    :headers="uploadHeaders"
                    :limit="files"
                    :disabled="disabled"
                    multiple
                    action=""
                    :file-list="fileList">
                <i class="el-icon-upload"></i>
                <div class="el-upload__text">将文件拖到此处，或<em>点击上传</em></div>
                <div slot="tip" class="el-upload__tip">上传文件大小不能超过 1G</div>
            </el-upload>
        </div>
    </template>
    
    <script type="text/ecmascript-6">
