如何制作一个发布版的ionic应用?

 
阅读更多
如何为Android APK签名,已经在这里说过了。这里说说如何保护源代码,把Hybrid App(混合移动应用)工程变到发布的状态。对于Hybrid App,如果不做任何处理,把apk文件解压后在assets文件夹里就能看到所有的源代码。

以下通过gulp tasks和cordova hooks来保护你的源代码。
・gulp tasks - ionic serve时执行
・cordova hooks - ionic build/run时执行

(0)创建一个ionic工程
cordova@5.0.0
ionic@1.3.20

C:\>ionic start myApp tabs


首先编译一个调试用的apk,以后的发布版apk作对比。
C:\>cd myApp
C:\myApp>cordova plugin add https://github.com/apache/cordova-plugin-whitelist.git
C:\myApp>ionic platform add android
C:\myApp>ionic build android
生成C:\myApp\platforms\android\build\outputs\apk\android-debug.apk


(1)(cordova hook)JS代码的Lint
   混淆JS代码的前提要保准JS代码没有错误。

安装jshint
C:\myApp>npm install jshint --save-dev
C:\myApp>npm install async --save-dev


hook文件
C:\myApp\hooks\after_prepare\01_jshint.js


编译
C:\myApp>ionic build android


引用
Linting www/js/controllers.js
Errors in file www/js/controllers.js
9:4 -> Missing semicolon. ->   }


ionic的sample工程controllers.js有错误,第九行缺少分号。
修改错误提示,直到build成功。

(2)(gulp task)把html模板转换为angularjs模板

安装gulp-angular-templatecache
C:\myApp>npm install gulp-angular-templatecache --save-dev


修改gulpfile.js
var templateCache = require('gulp-angular-templatecache');
var paths = {
  sass: ['./scss/**/*.scss'],
  templatecache: ['./www/templates/**/*.html']
};
gulp.task('templatecache', function (done) {
  gulp.src('./www/templates/**/*.html')
    .pipe(templateCache({standalone:true}))
    .pipe(gulp.dest('./www/js'))
    .on('end', done);
});
gulp.task('default', ['sass', 'templatecache']);
gulp.task('watch', function() {
  gulp.watch(paths.sass, ['sass']);
  gulp.watch(paths.templatecache, ['templatecache']);
});


修改ionic.project
{
  "name": "myApp",
  "app_id": "",
  "gulpStartupTasks": [
    "sass",
    "templatecache",
    "watch"
  ]
}


修改app.js
angular.module('starter', ['ionic', 'starter.controllers', 'starter.services', 'templates'])


修改index.html
<script src="js/templates.js"></script>


C:\myApp>npm install
C:\myApp>ionic serve
  生成C:\myApp\www\js\templates.js


把templates.js里的templateUrl改成和app.js的templateUrl一致
C:\myApp\www\js\templates.js
$templateCache.put("tabs.html", ...
->
$templateCache.put("templates/tabs.html", ...

(3)(gulp task)开启ng-strict-di

安装gulp-ng-annotate
C:\myApp>npm install gulp-ng-annotate --save-dev


修改gulpfile.js
var ngAnnotate = require('gulp-ng-annotate');
var paths = {
  sass: ['./scss/**/*.scss'],
  templatecache: ['./www/templates/**/*.html'],
  ng_annotate: ['./www/js/*.js']
};
gulp.task('ng_annotate', function (done) {
  gulp.src('./www/js/*.js')
    .pipe(ngAnnotate({single_quotes: true}))
    .pipe(gulp.dest('./www/dist/dist_js/app'))
    .on('end', done);
});
gulp.task('default', ['sass', 'templatecache', 'ng_annotate']);
gulp.task('watch', function() {
  gulp.watch(paths.sass, ['sass']);
  gulp.watch(paths.templatecache, ['templatecache']);
  gulp.watch(paths.ng_annotate, ['ng_annotate']);
});


修改ionic.project
{
  "name": "myApp",
  "app_id": "",
  "gulpStartupTasks": [
    "sass",
    "templatecache",
    "ng_annotate",
    "watch"
  ]
}


修改index.html
<script src="dist/dist_js/app/app.js"></script>
<script src="dist/dist_js/controllers.js"></script>
<script src="dist/dist_js/services.js"></script>
<script src="dist/dist_js/templates.js"></script>

<body ng-app="starter" ng-strict-di>


C:\myApp>ionic serve


js会被重新生成到一下,并且严格符合注入标准
C:\myApp\www\dist\dist_js\app

(4)(gulp task)合并JS、CSS文件

安装gulp-useref
C:\myApp>npm install gulp-useref --save-dev


修改gulpfile.js
var useref = require('gulp-useref');
var paths = {
  sass: ['./scss/**/*.scss'],
  templatecache: ['./www/templates/**/*.html'],
  ng_annotate: ['./www/js/*.js'],
  useref: ['./www/*.html']
};
gulp.task('useref', function (done) {
  var assets = useref.assets();
  gulp.src('./www/*.html')
    .pipe(assets)
    .pipe(assets.restore())
    .pipe(useref())
    .pipe(gulp.dest('./www/dist'))
    .on('end', done);
});
gulp.task('default', ['sass', 'templatecache', 'ng_annotate', 'useref']);
gulp.task('watch', function() {
  gulp.watch(paths.sass, ['sass']);
  gulp.watch(paths.templatecache, ['templatecache']);
  gulp.watch(paths.ng_annotate, ['ng_annotate']);
  gulp.watch(paths.useref, ['useref']);
});


修改ionic.project
{
  "name": "myApp",
  "app_id": "",
  "gulpStartupTasks": [
    "sass",
    "templatecache",
    "ng_annotate",
    "useref",
    "watch"
  ]
}


修改index.html
<!-- build:css dist_css/styles.css -->
<link href="css/style.css" rel="stylesheet">
<link href="css/ionic.app.css" rel="stylesheet">
<!-- endbuild -->

<!-- build:js dist_js/app.js -->
<script src="dist/dist_js/app/app.js"></script>
<script src="dist/dist_js/app/controllers.js"></script>
<script src="dist/dist_js/app/services.js"></script>
<script src="dist/dist_js/app/templates.js"></script>
<!-- endbuild -->


C:\myApp>ionic serve


生成以下文件:
C:\myApp\www\dist\index.html
C:\myApp\www\dist\dist_css\styles.css
C:\myApp\www\dist\dist_js\app.js

(5)(cordova hook)混淆代码

安装cordova-uglify
C:\myApp>npm install cordova-uglify --save-dev
C:\myApp>npm instal mv --save-dev


C:\myApp\hooks\after_prepare
01_jshint.js
020_remove_sass_from_platforms.js
030_clean_dev_files_from_platforms.js
040_move_dist_files_to_platforms.js
050_clean_obfuscation.js
060_uglify.js
文件夹里已经有的uglify.js可以删掉。

C:\myApp>ionic build android
  发布版apk C:\myApp\platforms\android\build\outputs\apk\android-debug.apk


至此完成!完整的工程代码,点击下载

assert文件夹对比,经过处理后只剩下了styles.css、app.js、index.html:


index.html对比
