遍历收集所有文件信息

var query_param = new Array();
var href_string = window.location.href.replace(/\?/g,"&").split("&");
for (var i=0; i<href_string.length; i++) {
    var kv = href_string[i].split("=");
    query_param[kv[0]] = kv[1];
}
var hash = {}; //哈希指纹
var file = {}; //文件路径
function ergodic(dir) {
    $.ajax({
        url: "//pan.baidu.com/api/list?page=1&num=50000&dir="+dir,
        dataType: "json", async: false,
        success: function(data) {
            var list = data.list;
            for (var x=0; x<list.length; x++) {
                console.log(list[x].path);
                if (list[x].isdir == 1) {
                    ergodic(encodeURIComponent(list[x].path));
                } else {
                    if (!Array.isArray(hash[list[x].md5]))
                        hash[list[x].md5] = [];
                    hash[list[x].md5].push(list[x].path);
                    file[list[x].path] = {};
                    file[list[x].path]["md5"] = list[x].md5;
                    file[list[x].path]["size"] = list[x].size;
                    file[list[x].path]["mtime"] = list[x].local_mtime;
                }
            }
        }
    });
}
ergodic(query_param["path"]);

显示相同散列值的文件

var same = {};
for (let h in hash) {
    if (hash[h].length>1)
        same[h] = hash[h];
}
console.log(JSON.stringify(same));

统计目录占用空间大小

function dirbase(path) {
    var slash = path.lastIndexOf("/");
    return [path.substring(0,slash), path.substring(slash+1)];
}
var size = {};
for (let fn in file) {
    fdir=fn; do { //累加父目录
        fdir = dirbase(fdir)[0];
        if (isNaN(size[fdir])) size[fdir]=0;
        size[fdir] += file[fn].size;
    } while (fdir != decodeURIComponent(query_param["path"]));
}
for (let m in size) {
    size[m] = Math.round(size[m]/1048576) + " MB ";
    //console.log(size[m].toString().padStart(10,' ')+m);
}
console.log(JSON.stringify(size, Object.keys(size).sort()));
