使用

wx.launchMiniProgram({
                    appId:"wxc708236add8cf9bb",
                    userName:"gh_e57764e1e6ba",
                    path:"",
                    miniprogramType:0
                });

wx.js

function launchMiniProgram(obj){
    var siteinfo = weex.requireModule('siteinfo');
    //miniprogramType
    //0表示正式版,1表示开发版,2表示体验版
    var data = {
        appId:obj.appId,
        userName:obj.userName,
        path:obj.path,
        miniprogramType:obj.miniprogramType != undefined ? obj.miniprogramType : 0
    }
   var result = siteinfo.launchMiniProgram(data);
    if(result == "ok"){
        if(obj.success){
            obj.success();
        }
    }else{
        if(obj.fail){
            obj.fail(result);
        }
    }

}
