通过MonkeyDev加载网络或者自己的cy脚本

前言

一开始想到这个功能的时候是因为Hank老师在我的微信公众号(alonemonkey)里面问了一个问题:

越狱设备

在越狱设备上面，可以将自己的脚本放到/usr/lib/cycript0.9/下面，然后通过@import xxx来导入即可使用自定义脚本里面封装的一些函数，极为方便。比如其自带的/usr/lib/cycript0.9/com/saurik/substrate/MS.cy就可以通过@import com.saurik.substrate.MS来导入这个模块，同样也可以放入一些自己的脚本来导入。那么在非越狱环境怎么去解决使用自定义脚本的问题呢？

非越狱设备

其实非越狱设备实现这个很简单，只要让cycript能找到我们自己的脚本所在的位置就行了，修改libcycript.cy文件的require.resolve函数，使其从当前应用目录或者沙盒目录里面去查找脚本，然后程序从网络下载脚本保存到沙盒目录就可以了，修改部分如下:

require.resolve = function(name) {
	......
	let library = GetLibraryPath();
    let path = ResolveFile(true, library + "/" + name + ".cy");
    if (path != null)
        return path;

    let document = GetDocumentPath();
    path = ResolveFile(true, document + "/cycript/" + name + ".cy");
    if (path != null)
        return path;
    ......

然后笔者在MonkeyDev的模块中增加了一个文件用于配置下载脚本的名字以及url:

key是脚本导入时候的名字，value是脚本所在的url，程序启动会自动下载脚本保存在Document的目录下面，然后在终端通过如下方式导入使用即可:
