我创建了一个项目，以下载解决方案中的多个文档。 而且它在我的本地IIS上运行良好，但是我陷入了一个奇怪的情况，我已经将该应用程序发布到了生产服务器，现在却出现以下错误：

Web Api控制器

public class DocumentController : BaseApiController
{
    private readonly Lazy<ICoreDataContext> _CoreDataContext;
    private readonly IDocumentsService _documentsService;
    protected ICoreDataContext CoreDataContext { get { return _CoreDataContext.Value; } }

    public DocumentController(IContextFactory contextFactory, IDocumentsService documentsService, IAppLog appLog) : base(appLog, contextFactory.Tenant)
    {
        _CoreDataContext = new Lazy<ICoreDataContext>(contextFactory.GetCoreContext);
        _documentsService = documentsService;
    }

    [HttpGet]
    [Route("MultiDocuments")]
    public async Task<HttpResponseMessage> DownloadMultiDocument(string documentIds)
    {
        try
        {
            var user = GetAuthenticatedUser();

            return await _documentsService.DownloadMultiDocumentAsync(user, documentIds);
        }
        catch (Exception e)
        {
            throw HttpError(e);
        }
    }
}

从以下DocumentsService类中，我像下面这样调用新创建的项目的DocumentService类，

  public class DocumentsService : CoreDataService, IDocumentsService
{
    private readonly IProjectsService _projectsService;
    private Dictionary<long, bool> projectAvailibility;
    private Dictionary<long, bool> projectDocumentTypeIdValidity;
    private readonly Services.IDocumentsService _documentService;

    public DocumentsService(IProjectsService projectsService, IContextFactory contextFactory, IAppLog appLog, IPermissionService permissionService,Services.IDocumentsService documentService): base(contextFactory, appLog, permissionService)
    {
        _projectsService = projectsService;
        _documentService = documentService;
    }

    public async Task<HttpResponseMessage> DownloadMultiDocumentAsync(IClaimedUser user, string documentIds)
    {
        return await _documentService.DownloadMultiDocumentAsync(user, documentIds);
    }
}

还有我新项目的服务类

public class DocumentService : IDocumentsService
{
    private readonly TenantInfo tenantInfo;
    private readonly ICoreDataContext coreDataContext;
    private readonly IPermissionService permissionService;

    public DocumentService(TenantInfo tenant, ICoreDataContext coreDataContext, IAppLog log, IPermissionService permissionService)
    {
        tenantInfo = tenant;
        this.coreDataContext = coreDataContext;
        this.coreDataContext.LazyLoadingEnabled = false;
       this.permissionService = permissionService;
    }

    public async Task<HttpResponseMessage> DownloadMultiDocumentAsync(IClaimedUser user, string documentId)
    {
       ...
       return ...;
    }
}

答案 0 :(得分：0)

抱歉，我犯了一个错误，但我们没有将新的项目引用包含在Web Api Controller项目中。
