小编and*_*dko的帖子

我正在使用自定义过滤器检查特定Action的用户访问权限,我有一个名为Admin的区域.当过滤器重定向未授权用户时,其重定向内部区域但不重定向到路径目录中的视图.
例如,当我访问http:// localhost/admin/roles时,我希望未经授权的用户将被重新安装到http:// localhost/authorized但不会被重新安装到http:// localhost/admin/authorized.
这是我如何使用过滤器:

   public override void OnAuthorization(AuthorizationContext filterContext)
        {
            DigitalHubOnlineStoreEntities db = new DigitalHubOnlineStoreEntities();
            RbacUser requestingUser = new RbacUser();
            var controllerid = RbacUser.GetControllerId(filterContext.ActionDescriptor.ControllerDescriptor.ControllerName);
            var actionid = RbacUser.GetActionId(filterContext.ActionDescriptor.ActionName, controllerid);          
            if (!requestingUser.GetUserPermission(HttpContext.Current.User.Identity.Name, actionid, controllerid))
            {
                filterContext.Result = new RedirectToRouteResult(new RouteValueDictionary { { "action", "Index" }, { "controller", "Unauthorized" } });
            }
        }

我正试图以这种方式POST到WebApi后端:

'use strict';
angular.module('auth', []).factory('authService', ['$http', '$q', '$localStorage', function ($http, $q, $localStorage) {

    var serviceBase = 'http://localhost:53432/api/';
    var authServiceFactory = {};

    var authentication = {
        isAuth: false,
        userName: ""
    };

    var saveRegistration = function (registration) {
        return $http.post(serviceBase + 'account/register', registration).then(function (response) {
            return response;
        });

    };

但我得到错误"message":"The origin 'http://evil.com/' is not allowed." 我明白这与CORS问题有关,所以我在模块中定义$sceDelegateProvider:

$sceDelegateProvider.resourceUrlWhitelist([
    'self',
    'http://localhost:53432' //This is webapi url
        ]);

但这也没有帮助.我该怎么解决这个问题？
在服务器端已启用CORS:

 [AllowAnonymous]
 [Route("Register")]
 [HttpPost]
 [EnableCors(origins: "http://localhost:8080", headers: "*", methods: "*")]
 public async Task<IHttpActionResult> Register(RegisterBindingModel …

据我所知,BEM根本不使用元素id.但是在这种情况下如何处理带有/ id的标签和输入？如果不使用id,使用屏幕阅读器的人将无法获得该标签用于该输入.我对吗？

当我尝试使用 Google Maps 加载组件时（props 已按预期传递给组件），我只是收到一条消息，说"Loading map..."但未加载带有标记的地图。控制台中也没有错误。这是组件。我在这里做错了什么？

import React, {Component} from 'react';
import {Map, InfoWindow, Marker, GoogleApiWrapper} from 'google-maps-react';
import { Constants } from './../../utils/constants';

export class MapContainer extends Component {

    state = {
        selectedPlace: ''
    }

    onMarkerClick = (e) => {
        this.setState({selectedPlace: e.Name});
    }

  render() {
    return (
      <Map 
        google={this.props.google}
        style={{width: '20vw', height: '45vh', 'top': '1.5rem'}}
        containerStyle={{width: '20vw', height: '30vh'}}
        initialCenter={{
          lat: this.props.lat,
          lng: this.props.lng
        }}
        zoom={15}>
        {this.props.markers.length > 0 && // Rendering multiple markers for 
          this.props.markers.map((m) => …

这里简单的linq到实体查询返回anonymous type.问题是其中一个int?值像参数一样用于获取另一个值int.

我知道的所有方法都不起作用.请告知如何解决这个问题.

public IQueryable<toursistdata> GetxTouristByCategory(string category)
        {
            var now = System.DateTime.MinValue;
            int i;
            switch (category)
            {
                case "arrival":
                    now = System.DateTime.Now.AddDays(-3);
                    var arrival = from a in db.xTourist
                                  where a.ArrDate >= now && a.Room == null
                                  select new toursistdata
                                  {
                                      kodt = a.Kod,
                                      name = a.Name,
                                      paxad = a.Paxad,
                                      paxch = a.Paxch,
                                      **//Here is h.Kod is int but KodH is int?**
                                      hotel = (from h in db.Address where h.Kod = (int)a.KodH.HasValue select h.NameC).FirstOrDefault(), …

我有点困惑,我应该如何实现多个异步任务的worklflow.例如 - Task1启动,当Task1完成,Task2启动,Task2完成启动TaskN等.
或者另一个词 - 异步任务如何通知"父"任务有关他的状态？我想可以在这里使用TaskStatus但不确定究竟如何.我在MSDN上搜索过,但没有这种模式的完整示例.
PS我编辑我的问题,以便专注于一个特定的问题.

我需要使用局部视图在Layout中渲染菜单（如果有更好的方法，请告诉我）。我这样做（在布局中）：

 @if (User.IsInRole("Admin"))
   {
      @Html.Partial("AdminMenu")
   }

这就是我在Controller中的称呼方式：

public ActionResult AdminMenu()
  {
      var am = _amr.GetAdminMenu();
      return PartialView(am);
  }

所以这是我的部分观点：

@model IEnumerable<DigitalHubOnlineStore.ViewModels.AdminMenuViewModel>

<div class="dropdown">
    <button class="btn btn-default dropdown-toggle" type="button" id="dropdownMenu1" data-toggle="dropdown" aria-haspopup="true" aria-expanded="true">
        Admin menu
        <span class="caret"></span>
    </button>
    <ul class="dropdown-menu" aria-labelledby="dropdownMenu1">
        @foreach (var item in Model)
        {
            <li><a href="@Html.DisplayFor(modelItem => item.MenuItemUrl)">@Html.DisplayFor(modelItem => item.MenuItemName)</a></li>
        }
    </ul>
</div>

Unfortunately it's not working.

我正在尝试Golang并尝试连接到 MS SQL。我正在使用github.com/denisenkom/go-mssqldbpackage 并sqlx用于此目的。但我收到错误：Unable to open tcp connection with host 'localhost:1433': dial tcp [::1]:1433: connectex: No connection could be made because the target machine actively refused it。
我完全确定数据库本身的一切，因为它与我的.Net 项目完美配合。这是代码：

package main

import (
    "database/sql"
    "fmt"
    "log"

    _ "github.com/denisenkom/go-mssqldb"
    "github.com/jmoiron/sqlx"
)

type Excursion struct {
    Id   int            `db:"id"`
    Name sql.NullString `db:"name"`
}

func main() {
    db, err := sqlx.Connect("sqlserver", "server=localhost;user id=DESKTOP-H74S9IT\\andrey.shedko;database=Flex;connection timeout=30;")
    if err := db.Ping(); err != nil {
        log.Fatal(err)
    }
    rows, …

我确实检查了这些多个问题，但到目前为止还没有答案。非常简单的正则表达式，在转义点附近给出错误“未终止的正则表达式文字”。正则表达式应该匹配./images/。

const regex = new RegExp(/\.\/images\/);
const options = {
    files: [
        './style/_styles.scss'
      ],
    from: [regex],
    to: ['./../dist/primeng-lib/images/']
  };

我使用该解决方案菲利普W¯¯从这里.对于单个文件,它可以正常工作.但对于多个文件我得到错误:NetworkError: 500 Internal Server Error.

        <input name="somefile" type="file" multiple />
        <input type="submit" value="Submit" />
    </form>
</body>

我怎样才能解决这个问题？

在我返回的服务方法中Observable,我试图通过Subject已完成的操作通知组件.

completed: Subject<boolean>

  constructor(private http: Http) {

  }

  loadItems(): Observable<FrontItemDto[]> {
    return this.http.get ( `${ServiceSettings.ApiUrl}/front` )
      .map ( res => {
        res.json ();
        if ( res.json () ) {
          this.completed.next ( true );
        }
      } )
      .catch ( (error: any) => Observable.throw ( error.json ().error || 'Server error' ) );
  }

这是组件监听的方式Subject:

ngOnInit(): void {
    this.getItems();
    this.sub = this.dataService.completed.subscribe(completed => {
      if (completed) {
        this.show = false;
      }
      });
  }

但我收到的错误是主题(已完成)未定义.我做错了什么？

我正在尝试从配置文件中进行简单的读取设置。这两个文件 - config.json 和 Settings.go，都在同一个文件夹中。但我总是得到"The system cannot find the file specified."我做错了什么？

func GetDbConnectionString() string {
    file, err := os.Open("config.json")
    if err != nil {
        log.Fatal(err)
    }
    decoder := json.NewDecoder(file)
    settings := Settings{}
    err1 := decoder.Decode(&settings)
    if err1 != nil {
        fmt.Println("error:", err1)
    }
    log.Print(&settings)
    return fmt.Sprintf("%s:%s@/%s", settings.login, settings.password, settings.database)
}
