  1. FIREFOX OS 应用开发、发布

  2. 使用HTML5, CSS 和 JavaScript 建立Web应用.

  3. Web应用

  4. 使用标准Web技术和Web工具开发,在浏览器中运行使用标准Web技术和Web工具开发,在浏览器中运行 Web站点添加少量信息可以改造为Web应用。 运行于多种平台:桌面浏览器、移动设备。

  5. Web应用源码结构 HTML文件 JS文件 CSS、图像及其他资源 Manifest文件

  6. 步骤

  7. 1. 使用HTML5, CSS, & Javascript 开发web应用 2. 为应用创建manifest文件 3. 发布/安装应用

  8. 1. 使用HTML5, CSS, & Javascript 开发web应用

  9. 重用现有的网站/web应用,或者从头开发新的web应用。重用现有的网站/web应用,或者从头开发新的web应用。 利用HTML5的功能: 本地存储(Local Storage) 离线清单(Offline manifest) 索引型数据库(Indexed DB) Web API 设计要适应不同的屏幕分辨率和屏幕方向。

  10. 2. 为应用创建manifest文件

  11. 创建一个manifest.webapp描述文件

  12. {"version": "1.0","name": “My App","description": “Simple app description!","icons": {“60": "/img/icon-60.png" },"developer": {"name": "Mozilla Labs","url": "http://mozillalabs.com" }, “permissions": {“settings": {“access", “readwrite” },“camera": {} },"installs_allowed_from": ["*"],"appcache_path": "/cache.manifest","locales": {“en": { "name": “My App", "description": " Simple app description " },“zh-CN": { “name”: “My App”, “description”: “应用的简单描述。" } },"default_locale": "en"}

  13. 应用权限(Permission) 部分功能敏感的WebAPI使用前需要声明权限 声明格式 {权限名: {访问属性}} 示例 访问属性包括: read readwrite readcreate createonly "permissions": { "device-storage:pictures":{ "access": "readwrite" }, "device-storage:videos":{ "access": "readwrite" }, "settings":{ "access": "readonly" }, "camera":{} },

  14. CSP Content Security Policy 保证内容安全,防止跨站攻击等 Privileged App的默认CSP default-src *; script-src 'self'; object-src 'none'; style-src 'self' 'unsafe-inline' Apps CSP

  15. default-src *; //默认接受所有内容 script-src 'self'; //不允许使用其他域的js, 不允许使用内联js, 不允许eval object-src 'none';//不允许使用Plugin style-src 'self' 'unsafe-inline'//不允许使用其他域的css,但可使用内联css Privileged App的默认CSP

  16. 3. 发布/安装应用

  17. 两种方式 托管的应用(Hosted App) Web站点托管应用 独立域名或子域名 打包的应用(Packaged App) 所有资源和文件打包为一个zip压缩包

  18. 托管的应用服务器设置 让Web Server识别manifest.webapp文件, 添加Content-type/MIME type: application/x-web-app-manifest+json

  19. Apache - in mime.types:application/x-web-app-manifest+json webapp Apache - in .htaccess:AddType application/x-web-app-manifest+json webapp NGinx - in mime.types:types { text/html html htm shtml; text/css css; text/xml xml; application/x-web-app-manifest+json webapp;}

  20. IIS:In IIS Manager, right-click the local computer, and click Properties.Click the MIME Types button.Click New.In the Extension box, type the file name extension.In the MIME type box, type a description that exactly matches the file type defined on the computer.Click OK.

  21. 验证应用

  22. 在线安装托管应用

  23. var request =navigator.mozApps.install("http://mozillalabs.com/MozillaBall.webapp", { user_id: "some_user" });request.onsuccess=function(){// Success! Notification, launch page etc} request.onerror=function(){// Failed. this.error.name has details}

  24. Thank You!
