Angularjs 带有角度错误的post：可能未处理的拒绝

我刚刚设法让我的$http帖子在Angular.com上运行，其中管理员只能对数据进行编辑，例如授予用户成为管理员或阻止用户的权限，并更新用户的描述。我写下我学到的每一件事，但当我在命令提示符下发布数据时，它会给我以下错误：

错误： {密码： {MongooseError:密码应包含#$@！大小写，并且应介于6到8个字符之间 at validator错误（C:\jobapp\node\u modules\mongoose\lib\error\validator.js:24:11） 验证时（C:\jobapp\node\u modules\mongoose\lib\schematype.js:732:13） 位于C:\jobapp\node\u modules\mongoose\lib\schematype.js:802:5 在model.validator（C:\jobapp\node\u modules\mongoose validator\lib\mongoose validator.js:55:16） 异步验证时（C:\jobapp\node\u modules\mongoose\lib\schematype.js:791:29） 不推荐使用时（内部/util.js:41:15） 在C:\jobapp\node\u modules\mongoose\lib\schematype.js:760:9 at Array.forEach（本机） 在SchemaString.SchemaType.doValidate（C:\jobapp\node\u modules\mongoose\lib\SchemaType.js:738:19） 在C:\jobapp\node\u modules\mongoose\lib\document.js:1479:9 at _combinedTickCallback（内部/流程/下一步_tick.js:73:7） 在进程中。_tick回调（内部/process/next_tick.js:104:9） 消息：“密码应包含#$@！大小写，并且应在6到8个字符之间”，名称：“ValidatorError”， 属性：[对象]， 种类：'用户定义'， 路径：“密码”， 价值：‘$2a$10$cNJ6jAYs8bLZy5qE4RSMoeKbvz1PFZPRkK8T1ODxnD5QNRFxCrH5K’， 原因：未定义}}， 消息：“用户验证失败”， 名称：'ValidationError'} {MongooseError:用户验证失败 在ValidationError}

当我刷新页面时，我在控制台中遇到了以下错误：

angular.js:14525可能未经处理的拒绝：{“数据”：null，“状态”：-1，“配置”：{“方法”：“PUT”，“transformRequest”：[null]，“transformResponse”：[null]，“jsonpCallbackParam”：“回调”，“url”：“/sign/edit/”，“数据”：{“\u id”：“590470c0d9f3c1187002431c”，“aboutme”：“dsdjksjkdjk”，“标头”：{“接受”：“应用程序/json，文本/plain，/”，“内容类型”：“application/json；charset=utf-8”，“x-access-token”

我的服务器中的代码在Express.js中调用我的MongoDB：

    //insert new value
    rout.put('/edit', function(req, res){
        var editUser = req.body._id;
        if(req.body.permission) var newPermission = req.body.permission;

        if(req.body.aboutme) var newAbout = req.body.aboutme;
        User.findOne({username: req.decoded.username},function(err,mainUser){
    if(err) throw err;
    if(!mainUser){
    res.json({success:false, message: 'no User found'});
    }else{

我在这些错误中坚持了两天多，所以有人知道为什么会发生这种情况吗？我必须做什么？我肯定有错误，但我不知道-1的状态在哪里通常表示CORS问题。浏览器因为违规而阻止了请求，服务器无法授权。@georgeawg感谢它帮助我解决了这个问题o解决此问题//如果密码未更改或是新的，则忽略中间件如果（！user.isModified（'password'））返回下一步（）；//如果密码未更改或是新的，则忽略中间件会导致密码在每次编辑过程中都在更改，并且可能超过passeord验证的长度
