1.嵌入H5頁面，需要采用web-view標簽，如下：
<web-view src="/hybrid/html/index.html" @message="handleMessage"></web-view>
注意：
- h5頁面必須在項目目錄：/hybrid/html/下面，因為這樣uni-app才不會進行編譯
- @message事件是h5頁面向應用發送數據的回調
2.h5頁面代碼：
-
<!DOCTYPE html>
<html lang="zh">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>上傳文件</title>
