无法加载文件或程序集'System.Web.Http.Owin'

Question

我做了升级MVC5和Web Api 2.2,我创建了MVC Web应用程序.在其中,我添加了为我的主项目定义为子项的空Web API,我想要的是保护我的数据,路由运行良好.但有一些数据我想在我的上下文,当尝试进入localhost时:34862/api/account/test我收到错误

这是我在ApiController中的代码

[RoutePrefix("api/account")]
public class AccountController : ApiController
{
    private readonly IAccountUoW _iaUoW;

    public AccountController(IAccountUoW iaUoW)
    {
        _iaUoW = iaUoW;
    }

    [Route("")]
    [HttpGet]
    public string Get()
    {
        return "test";
    }

    [Authorize]
    [Route("test")]
    [HttpGet]
    public async Task<IHttpActionResult> GetTourInfos()
    {
        var ctx = (OwinContext)Request.GetOwinContext();
        ClaimsPrincipal user = ctx.Authentication.User;
        IEnumerable<Claim> claims = user.Claims;
        return Ok();
    }
}

我从NuGet添加的参考资料

• Microsoft ASP.NET Web API 2.2
• Owin
• Microsoft.Owin
• Microsoft.Owin.Host.SystemWeb
• Microsoft.Owin.Security.Cookies
• Microsoft.Owin.Security.OAuth

我还检查了我从我的主项目添加到我的子项目的引用,它与我的子项目具有相同的版本

这里来自子项目的packages.config

这是我的错误

无法加载文件或程序集'System.Web.Http.Owin,Version = 5.2.2.0,Culture = neutral,PublicKeyToken = 31bf3856ad364e35'或其依赖项之一.该系统找不到指定的文件.

从包管理器,我也运行Update-Package Microsoft.AspNet.WebApi -reinstall,但仍然有错误,我缺少什么？来人帮帮我？任何答案将不胜感激,提前谢谢.

Answer 1

问题可能是Web Api 2.2使用microsoft.owin 2.0.2版本.您可以在web.config中更改行为.

如果您的microsoft.owin版本是3.0.0,则在"bindingRedirect"行中,在"newVersion"中设置3.0.0

<runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="Microsoft.Owin" publicKeyToken="31bf3856ad364e35" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-2.0.2.0" newVersion="3.0.0" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>

看待,
