Javascript 登录失败和授权错误，REST在环回中

javascript node.js rest loopbackjs

Javascript 登录失败和授权错误，REST在环回中,javascript,node.js,rest,loopbackjs,strongloop,Javascript,Node.js,Rest,Loopbackjs,Strongloop,我正在尝试为我的loopback node.js应用程序创建一个默认的引导时管理员，该应用程序使用cloudant作为数据库。但每次我启动应用程序时，默认管理员创建的登录都会失败。代码是否有问题，导致数据没有存储在cloudant数据库或其他什么地方 另外，如果我手动创建管理员，授权的REST任务将无法工作，而是引发401 Authorization required错误 common/models/user.json如下所示： { "name": "user", "ba

您只需要检查管理员帐户是否存在。没有必要破坏任何东西

//server/boot/admin.js

'use strict';

var async = require('async');

module.exports = function(app, cb) {
  /*
   * Adding necessary admin `User`s to database.
   */

  var User = app.models.User;
  var Role = app.models.Role;
  var RoleMapping = app.models.RoleMapping;

  var admin = {
    username: 'admin',
    email: 'admin@admin.com',
    password: '123456'
  };

  User.count({email: admin.email}, function(err, count) {
    if (err) return cb(err);
    if (count > 0) return cb(null);
    User.create(admin, adminHandler);
  });

  var adminHandler = function(err, user) {
    if (err) return cb(err);

    async.waterfall([
      function(callback) {
        Role.findOne({where: {name: 'ADMIN'}}, function(err, role) {
          if (err) return callback(err);
          if (role) return callback(null, role);
          Role.create({name: 'ADMIN'}, callback);
        });
      },
      function(role, callback) {
        role.principals.create({
          principalType: RoleMapping.User,
          principalId: user.id
        }, callback);
      }
    ], function(err, result) {
      if (err) return cb(err);
      cb(null);
    });
  };

您忘记了异步调用方法
destroyAll
，
find
是异步的，您可以像同步方法一样调用。使用
async
模块同步所有订单，以便在两次呼叫之间保持订单。请详细说明？？？完成，但仍不起作用。我不知道，但不知怎的，启动文件夹中的script.js文件在应用程序启动时没有执行。
