1. 七牛地址javascript-sdk官方地址：https://developer.qiniu.com/kodo/sdk/1283/javascript
2. github中七牛sdk上传参考代码：https://github.com/qiniu/js-sdk
3. 上传过20M的相机高清图片，需要在图片后面添加后缀： +?'<span class="colour" style="color: rgb(137, 202, 120);">imageslim/3/h/136',</span>
<span class="colour" style="color: rgb(137, 202, 120);">这是图片处理的方法：</span>
<span class="colour" style="color: rgb(137, 202, 120);">https://developer.qiniu.com/dora/manual/1279/basic-processing-images-imageview2</span>
<span class="colour" style="color: rgb(0, 0, 0);">备注：七牛上传使用七牛sdk，图片展示时候被vue框架会自动压缩，上传成功后resolve()会返回两个参数：</span>hash、key, 使用返回的key字段与后台返回的七牛域名进行拼接，这就组成了新的图片地址，但是返回的key是没有类似 .jpg 后缀的，所以需要在上传前给 七牛sdk的key换成自己的标识
<span class="colour" style="color: rgb(55, 71, 79);">在Node安装运行七牛的包 npm</span> <span class="colour" style="color: rgb(55, 71, 79);">install qiniu-js</span>
4.具体代码参考七牛上传（如下）：
