我想知道是否有可能让Busboy分别解析字段和文件.(我已经删除了,bodyParser因为你可以很容易地用临时文件填充硬盘驱动器.)

例如 - 解析器发布字段的中间件(用于所有POST请求)

if (req.method === 'POST') {
    var form = new busboy({ headers: req.headers, limit: { files: 0 } });

    form.on('field', function (fieldname, val, valTruncated, keyTruncated) {
        req.params.body[fieldname] = val;
    });
    form.on('finish', function () {
        next();
    });
    return req.pipe(form);

} else { next(); }

然后在上传页面上使用以下内容,它使用Busboy来获取发布的文件.

app.post('/fm/file/upload/:folder', function (req, res) {
    var isFrame = helpers.toBool(req.param('frame'), false),
        uploadService = fmUploadService.create(),
        userId = res.locals.info.User.Id,
        folder = helpers.toInt(req.param('folder', 0));

uploadService.processUploads(userId, folder, req, res, function (uploadError, allowedAccess, files) {
        if (uploadError) …

我有一个查询,使用公用表表达式检索页面的所有模块和子模块.是否可以多次使用cte的结果？

例

WITH top_level_modules (
[AppContentModuleID]
,[SortIndex]
,[ContentHolderName]
,[OwnerType]
,[AppContentModuleGuid]
,[parent_AppContentModuleID]
,[ModuleID]
,[RenderIDTag]
,[WrapperType]
,[Level]
)
AS
( 
SELECT amcp.[AppContentModuleID]
    ,amcp.[SortIndex]
    ,amcp.[ContentHolderName]
    ,1
    ,amc.[AppContentModuleGuid]
    ,amc.[parent_AppContentModuleID]
    ,amc.[ModuleID]
    ,amc.[RenderIDTag]
    ,amc.[WrapperType]
    ,0 AS [Level]
FROM [dbo].[application_module_content_page] amcp
INNER JOIN [dbo].[application_module_content] amc on amcp.[AppContentModuleID] = amc.[AppContentModuleID]
WHERE amcp.[PageID] = @PageID
UNION
SELECT amcm.[AppContentModuleID]
    ,amcm.[SortIndex]
    ,amcm.[ContentHolderName]
    ,2
    ,amc.[AppContentModuleGuid]
    ,amc.[parent_AppContentModuleID]
    ,amc.[ModuleID]
    ,amc.[RenderIDTag]
    ,amc.[WrapperType]
    ,0
FROM [dbo].[application_module_content_masterpage] amcm
INNER JOIN [dbo].[application_module_content] amc on amcm.[AppContentModuleID] = amc.[AppContentModuleID]
WHERE amcm.[AppMasterPageID] = @MasterPageID
),
child_modules AS 
(
SELECT tlm.[AppContentModuleID]
    ,tlm.[SortIndex] …

如果我有一个类接受从IUser派生的泛型类型,我该如何避免此错误消息

无法隐式转换ElimCMS.Service.Users.someclass<ElimCMS.DataModel.Users.User>为ElimCMS.Service.Users.Isomeclass<ElimCMS.DataModel.Users.IUser>.存在显式转换(您是否错过了演员？)

例

   public interface Isomeclass<TUser>
   where TUser : class, IUser
   {

    string test(TUser user);
    TUser returnUser();
   }

   public class someclass<TUser> : Isomeclass<TUser>
   where TUser : class, IUser, new()
   {
    public string test(TUser user)
    {
        string email = user.EMail;
        user.EMail = "changed:" + email;

        return email;
    }


    public TUser returnUser()
    {
        throw new NotImplementedException();
    }
}

 Isomeclass<ElimCMS.DataModel.Users.IUser> servicetest = new someclass<ElimCMS.DataModel.Users.User>();
