1.JSPatch 准备
地址:https://github.com/bang590/JSPatch
框架:libz.1.tbd , JavaScriptCore.framework
2.cocospod(可得到的三个文件)
JPEngine.h,JPEngine.m,JSPatch.js
3.Demo(重要的三个文件夹)
Extensions,JSPatch,Loader
＊＊＊＊＊＊＊＊测试＊＊＊＊＊＊＊＊
1.在本地生成一个main.js文件
require('SecondViewController')
defineClass('ViewController',{
rightClick:function(sender){
var vc = SecondViewController.alloc().init()
self.navigationController().pushViewController_animated(vc,YES)
}
})
2.JSPatchDemo
2.1 ViewController
@interface ViewController ()
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"right" style:(UIBarButtonItemStylePlain) target:self action:@selector(rightClick:)];
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
// [SecondViewController setGlBlock:^(NSString *) {
//
// }];
}
#pragma mark - click
- (IBAction)rightClick:(id)sender{
NSLog(@"某某某");
}
@end
2.2 AppDelegate (执行main.js)
2.2.1 使用JPEngine (点击ViewController的rightNavigationItem 会跳转SecondViewController)
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
[JPEngine startEngine];
NSString *sourcePath = [[NSBundle mainBundle] pathForResource:@"main" ofType:@"js"];
NSString *script = [NSString stringWithContentsOfFile:sourcePath encoding:NSUTF8StringEncoding error:NULL];
[JPEngine evaluateScript:script];
return YES;
}
2.2.2 使用JPLoader(5s前点击ViewController的rightNavigationItem 会打印'某某某',5s后会跳转SecondViewController)
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(5.0 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
[JPLoader runTestScriptInBundle]; //5.0秒之前执行 本来就有的方法，5.0秒之后执行js里面的方法
[JPLoader setLogger:^(NSString *log) {
NSLog(@"hgl say:\"%@\"",log);
}];
});
return YES;
}
＊＊＊＊＊＊＊＊＊线上＊＊＊＊＊＊＊＊＊＊＊
1.服务端
文件管理 baseURL/version/v2.zip (version:app版本号,v2:js版本号)
接口需求(request: {version:当前版本号,index:js版本号(为空是表示未下载过js.main)},
response:{state:状态码,update:是否需要下载,operate:是否需要执行当前js})
2.打包main.js
$php pack.php main.js -o v2 (pack.php 存在于Loader文件夹中,pack.php需要RSA私钥)
使用RSA加密验证 (只是为了验证，无法避免转包。如若需要可使用https协议)
*生成RSA公钥私钥
1.安装openssl
sudo apt-get install openssl
2.生成RSA私钥 //该命令会生成1024位的私钥
openssl genrsa -out rsa_private_key.pem 1024
3.把RSA私钥转换成PKCS8格式
openssl pkcs8 -topk8 -inform PEM -in rsa_private_key.pem -outform PEM –nocrypt
4.生成公钥
openssl rsa -in rsa_private_key.pem -out rsa_public_key.pem -pubout
3.客户端
3.1 请示是否需要下载js，是否需要执行js
3.2 下载main.js
[JPLoader updateToVersion: callback:^(NSError *error) {
}];
3.3 下载完成之后执行main.js
[JPLoader updateToVersion: callback:^(NSError *error) {
[JPLoader run];
}];
*注:1.JPLoader中需要放入RSA的公钥
2. updateToVersion方法会下载zip包，zip解压-> RSA验证 ->成功 -> 回调

注：2017-03 苹果官网 已经不允许app 动态修改一些东西，上App Store的应用最好先别使用这个东西。企业版app 还是可以用的。
