小编Gre*_*reg的帖子

我已经浏览了多个博客等,试图找出如何使用Web API 2配置StructureMap,但没有一个实现对我有用.混淆似乎是围绕MVC使用的不同IDependency Resolver和Web API使用的IDependency Resolver.

首先,哪个是正确的Nuget包,其次,如何使用纯Web API 2项目进行配置？

谢谢

这就是我到目前为止所做的工作.它是否正确？

 public class StructureMapControllerActivator : IHttpControllerActivator
{
    private readonly IContainer _container;

    public StructureMapControllerActivator(IContainer container)
    {
        if (container == null) throw new ArgumentNullException("container");
        _container = container;
    }

    public IHttpController Create(HttpRequestMessage request, HttpControllerDescriptor controllerDescriptor, Type controllerType)
    {
        try
        {
            var scopedContainer = _container.GetNestedContainer();
            scopedContainer.Inject(typeof(HttpRequestMessage), request);
            request.RegisterForDispose(scopedContainer);
            return (IHttpController)scopedContainer.GetInstance(controllerType);
        }
        catch (Exception e)
        {
            // TODO : Logging
            throw e;
        }
    }
}

鉴于这个json？

[
 { 
  "CompanyId":20,
  "CompanyName":"Walmart",
  "CompanyContacts":[
                     {
                      "CompanyId":20,
                      "FirstName":"Bob",
                      "LastName":"Green",
                      "Email":"bob@test.com",
                      "Phone":"1234567",
                      "IsActive":false
                     }
                    ]
 }
]

我使用Angular前端连接到WEB API 2后端.失败的用例如下.当用户注册成功注册时,他们必须登录系统并重定向到新页面以收集更多信息.我正在使用TOKENS进行身份验证.

我在WebAPI配置中启用了CORS:

 var cors = new EnableCorsAttribute("http://localhost:7812", "*", "*");
        config.EnableCors(cors);   

注册请求成功,响应头具有所需的CORS头:

**Access-Control-Allow-Credentials:true
Access-Control-Allow-Origin:http://localhost:7812**
Content-Length:0
Date:Sun, 24 Aug 2014 09:31:55 GMT
Server:Microsoft-IIS/8.0
X-Powered-By:ASP.NET
X-SourceFiles:=?UTF-8?B?QzpcUHJvamVjdHNcVGVzdGluZ1xNYWx0QXBhcnRtZW50c1xNYWx0YXBhcnRtZW50cy5BUElcTWFsdGFwYXJ0bWVudHMuQVBJXGFwaVxhY2NvdW50XHJlZ2lzdGVy?=

在下一步中,我尝试将用户登录到系统.作为登录的一部分,前端从服务器请求TOKEN Request URL:http://localhost:7802/token.请求标头再次发送一个Origin标头,Origin:http://localhost:7812但这次我收到错误:XMLHttpRequest cannot load http://localhost:7802/token. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:7812' is therefore not allowed access.

有人有主意吗？

总 NOOB 问题。我已经使用新的 linqpad 大约 20 分钟了。伟大的！

但现在我想删除数据库中的一行。我使用的是 EF5.0 连接。我似乎无法在帮助文件或网络上找到任何内容。我唯一能找到的是 DeleteOnSubmit，它不适用于 EF（据我所知）。我也试过 DeleteObject 也不起作用。这是我尝试过的。

var co = Companies.First();
co.Dump();

Companies.DeleteObject(co);

我正在尝试使用Web API 2设置结构图ver 3.0.5.0.

我已经遵循了这个实现:使用ASP.NET Web API 2.1配置依赖注入

但是,在针对ComplexesController进行攻击时出现此错误:

尝试创建"ComplexesController"类型的控制器时发生错误.确保控制器具有无参数的公共构造函数.

谁能看到我的structuremap配置有什么问题？永远不会调用Create方法.

这是我的实施:

public class StructureMapControllerActivator : IHttpControllerActivator
{
    private readonly IContainer _container;

    public StructureMapControllerActivator(IContainer container)
    {
        if (container == null) throw new ArgumentNullException("container");
        _container = container;
    }

    public IHttpController Create(HttpRequestMessage request, HttpControllerDescriptor controllerDescriptor, Type controllerType)
    {
        try
        {                
            var scopedContainer = _container.GetNestedContainer();
            scopedContainer.Inject(typeof(HttpRequestMessage), request);
            request.RegisterForDispose(scopedContainer);
            return (IHttpController)scopedContainer.GetInstance(controllerType);
        }
        catch (Exception e)
        {
            // TODO : Logging
            throw e;
        }
    }
}

这个方法在我的创业公司......

public void InitializeContainer()
    {
        // STRUCTURE MAP …

我使用Kendo Grid进行内联编辑.当我单击"更新"按钮时,将使用此签名对我的控制器方法进行POST.控制器操作被命中,因此POST正在运行.

[HttpPost]
    public HttpResponseMessage SaveAccountAdmin(string jsonCompanyContacts)

但是,更新操作中的POST数据永远不会到达 - 它始终为null.

update: {
              url: "/Company/SaveAccountAdmin",
              contentType: "application/json; charset=utf-8",
              type: "POST",
              dataType: "json",
              data: {
                  jsonCompanyContacts: "John Doe"
              }
          },

这是完整的数据源代码.

var dataSource = new kendo.data.DataSource(
  {
      batch: false,
      pageSize: 10,

      transport: {
          create: {
              url: "/Company/SaveAccountAdmin",
              contentType: "application/json; charset=utf-8",
              type: "POST",
              dataType: "json"
          },

          read: {
              url: "/Company/ReadAccountAdmin"
          },

          update: {
              url: "/Company/SaveAccountAdmin",
              contentType: "application/json; charset=utf-8",
              type: "POST",
              dataType: "json",
              data: {
                  jsonCompanyContacts: "John Doe"
              }
          },
          //destroy: {},

          parameterMap: function …

我有2个阵列,我想要一个笛卡尔积.举个例子:

客户数组:

[10,A]
[11,B]

债务人数组:

[88,W]
[99,X]

我想生成一个新的customerDebtor数组:

[10,A,88,W]
[10,A,99,X]
[11,B,88,W]
[11,B,99,X]

我正在尝试使用此代码:

for (var i = 0; i < customerArray.length; i++) {
    for (var l = 0; l < debtorArray.length; l++) {
        $.each(customerArray[i], function (ndx, val) {
            //???? push values into customerDebtorMatrix array
        });
    }
}

我正在尝试使用Angular UI typeahead.我的问题是下拉列表没有显示.正确调用远程数据并返回数据...但下拉列表拒绝显示...

<td colspan="5">
   <pre>Model: {{selected| json}}</pre>
   <input id="AutoCompleteDebtor" 
          type="text" 
          data-ng-model="selected" 
          data-typeahead="debtor for debtor in Debtors($viewValue)" 
          class="form-control input-sm" 
          placeholder="Enter 3 letters of Debtor Name" />
</td>

更新:好的 - 它与字符串名称数组配合良好,但我如何使用对象？

<!DOCTYPE html>
<html data-ng-app="myApp">
<head>
<title>Angular Typeahead</title>
<link href="Content/bootstrap/bootstrap.min.css" rel="stylesheet" />
<script src="Scripts/angular.min.js"></script>
<script src="Scripts/ui-bootstrap-tpls-0.6.0.min.js"></script>
<script>
    angular.module('myApp', ['ui.bootstrap'])
    .controller('SimpleController', function ($scope) {
        $scope.people = [
            { name: 'Alan', age: 23 },
            { name: 'Bruce', age: 24 },
            { name: 'Celine', age: 53 },
            { name: 'Dan', age: 43 },
            { …

我想我可能有配置问题.循环遍历一个对象数组时出错.这是错误.正在将对象数组加载到视图中,它们看起来是正确的.它只是爆炸的"repeat.for".

视图 …

如在标题中,我如何防止2个列表之间的重复.我试图在#selected列表中停止重复.我怀疑它在接收事件中完成但我没有运气.

    $(function () {

    $("#options").sortable({
        connectWith: $("#selected"),
        helper: 'original',
        revert: true,
        tolerance: "pointer",
    });

    $("#selected").sortable({
        connectWith: $("#options"),
        helper: 'original',
        receive: function (event, ui) {            
        },
    });

    $("#options,#selected").disableSelection();

    $("#SkillGroups").change(function () {
        $.ajax({
            type: "POST",
            url: "/Contractor/Contractor/GetSkillsBySkillGroup",
            data: { skillGroupId: $("#SkillGroups").val() },
            success: function (result) {
                $loadList(result);
            }
        })
    });
});

我刚决定尝试Automapper.

我在我的项目中写了几个单元测试,当我"全部运行"时,它们都按预期通过.但是,当我运行单独的测试时,它们会失败...所以,是否有一些特殊的设置我错过了？

这是代码.当我全部运行时,这通过了测试.

 [TestMethod]
    public void Mappings_ConfigureMappings_pass()
    {           
        Mapper.CreateMap<Address, AddressDTO>();
        Mapper.AssertConfigurationIsValid();
    }

但是当我运行实际的映射测试时,测试失败了.

[TestMethod]
    public void Mappings_ViewModel_Address_ToDTO_pass()
    {

        var address = new Address()
        {
            Address1 = "Line1",
            Address2 = "Line2",
            Address3 = "Line3",
            Country = "ROI",
            County = "Co Dublin",
            PostCode = "ABC",
            TownOrCity = "Dublin"
        };

        AddressDTO addressDTO = Mapper.Map<Address, AddressDTO>(address);
        Assert.IsNotNull(addressDTO);
        Assert.AreEqual("ROI", addressDTO.Country);
        Assert.AreEqual("Dublin", addressDTO.TownOrCity);
    }

这里是相关的类......你可以看到它们是相同的,为什么测试失败？这是我在设置中遗漏的东西吗？

public class Address 
{
    public string Address1 { get; set; }
    public string Address2 { get; set; }
    public string Address3 …
