我无法连接到SQL Server,我的项目的连接字符串是:

<add name="Teleport_DEVEntities" connectionString="metadata=res://*/Data.Model.AdvertisingModel.csdl|res://*/Data.Model.AdvertisingModel.ssdl|res://*/Data.Model.AdvertisingModel.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=*****;initial catalog=****;integrated security=True;MultipleActiveResultSets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" />

我收到此错误:

不支持关键字:'元数据'

我该如何解决这个错误？

我在我的项目中使用webapi上传文件.我正在和邮递员一起测试.但是,Request.Content.IsMimeMultipartContent()始终返回false.

邮差截图:

FileUploadController代码:

public async Task<HttpResponseMessage> UserImageUpload()
    {
        try
        {
            if (!Request.Content.IsMimeMultipartContent())
            {
                throw new HttpResponseException(HttpStatusCode.UnsupportedMediaType);
            }

            var userImageUploadPath = HttpContext.Current.Server.MapPath(CommonParameters.UserProfileImageServerPath);
            var streamProvider = new CustomMultipartFormDataStreamProvider(userImageUploadPath);
            await Request.Content.ReadAsMultipartAsync(streamProvider);

            var files = new List<string>();
            foreach (MultipartFileData file in streamProvider.FileData)
            {
                files.Add(Path.GetFileName(file.LocalFileName));
            }

            return Request.CreateResponse(HttpStatusCode.OK, files);
        }
        catch (Exception exception)
        {
            logger.ErrorFormat("An error occured in UserImageUpload() Method - Class:FileUploadController - Message:{0}", exception);
            return Request.CreateResponse(HttpStatusCode.BadRequest);
        }
    }

我在项目中使用基于OAuth Bearer令牌的身份验证.成功登录请求后,我收到以下json.

{"access_token":"some token","token_type":"bearer","expires_in":1232}

我想在json下面发送更多信息数据.我创建了身份验证票证并添加了authenticationproperties.但它并没有起作用.

GrantResourceOwnerCredentials方法代码:

public override async Task GrantResourceOwnerCredentials(OAuthGrantResourceOwnerCredentialsContext context)
    {
        try
        {
            context.OwinContext.Response.Headers.Add("Access-Control-Allow-Origin", new[] { "*" });
            var schoolId = context.UserName;
            var password = context.Password;
            logger.InfoFormat(CommonConstants.LoginInfoLogMessageFormat, schoolId);
            var loginOperator = new LoginManager();
            var result = loginOperator.IsUser(schoolId, password);
            if (result)
            {
                var identity = new ClaimsIdentity(context.Options.AuthenticationType);
                identity.AddClaim(new Claim("sub", context.UserName));
                identity.AddClaim(new Claim("role", "user"));
                var authenticationProperties = GetUserAuthenticationProperties();
                var authenticationTicket = new AuthenticationTicket(identity, authenticationProperties);
                context.Validated(authenticationTicket);
            }
            else
            {
                context.SetError("invalid_grant", "Kullan?c? ad? veya ?ifre yanl??.");
            }
        }
        catch (Exception exception)
        { …
