Answer 1

在原生层面window对象不支持

Answer 2

找到答案了 是在页面跳转时获取页面uri阶段出问题了 使用了window.location.host andorid 这边不认识这个window

exports.getBaseUrl = function (bundleUrl, isnav) {

bundleUrl = new String(bundleUrl);
var nativeBase;
var isAndroidAssets = bundleUrl.indexOf('file://assets/') >= 0;

var isiOSAssets = bundleUrl.indexOf('file:///') >= 0 && bundleUrl.indexOf('WeexDemo.app') > 0;
if (isAndroidAssets) {
    nativeBase = 'file://assets/dist/';
}
else if (isiOSAssets) {
    nativeBase = bundleUrl.substring(0, bundleUrl.lastIndexOf('/') + 1);
}
else {
    // var host = window.location.host;  这个在浏览器中可以用 
    var host;
    var matches = /\/\/([^\/]+?)\//.exec(bundleUrl);
    if (matches && matches.length >= 2) {
        host = matches[1];
    }
    // alert("er:::"+host);
    //此处需注意一下,tabbar 用的直接是jsbundle 的路径,但是navigator是直接跳转到新页面上的.
    // if (typeof window === 'object') {
    //     nativeBase = isnav ? 'http://' + host + '/index.html?page=./dist/' : '/dist/';
    // } else {
    //     nativeBase = 'http://' + host + '/dist/';
    // }
}
// alert("nativeBase:  "+nativeBase);
nativeBase="http://"+host+"/dist/";
return nativeBase;

};
