用了七牛的表单上传，在本地可以成功实现，但是部署上线后，因为服务器设置为https的网址，所以被chrome浏览器禁止了向upload.qiniu.com发送post请求的动作，有哪些办法可以解决？
错误信息：
Mixed Content: The page at 'https://my-app-url' was loaded over HTTPS, but requested an insecure XMLHttpRequest endpoint 'http://upload.qiniu.com/'. This request has been blocked; the content must be served over HTTPS.
