identity

问题 I would like to limit the possibility of creating more than one account in a web application by a single person. How to do this? If you know how, you can directly answer this question. If you don't know or you don't understand the question, please read below where I try to give more information. The problem can be solved by assigning a unique persistent ID to each person registering in the application. If the person wants to set up another account, it won't be possible because he/she will

问题 I have been following the blog at http://hasini-gunasinghe.blogspot.com/2011/12/entitlement-service-xacml-pdp-as-web.html but I cannot connect to identity server, every time I try I get the following error: org.apache.axis2.AxisFault: Connection has been shutdown: javax.net.ssl.SSLException: java.lang.RuntimeException: Unexpected error: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty at org.apache.axis2.AxisFault.makeFault(AxisFault.java:430) at

问题 I want to generate a custom identity column related to type of product. Can this query guaranty the order of identity and resolve concurrency. This is a sample query: BEGIN TRAN INSERT INTO TBLKEY VALUES((SELECT 'A-' + CAST(MAX(CAST(ID AS INT)) + 1 AS NVARCHAR) FROM TBLKEY),'EHSAN') COMMIT 回答1: Try this: BEGIN TRAN INSERT INTO TBLKEY VALUES((SELECT MAX(ID) + 1 AS NVARCHAR) FROM TBLKEY WITH (UPDLOCK)),'EHSAN') COMMIT When selecting the max ID you acquire a U lock on the row. The U lock is

问题 As per the title I have attempted to setup a simple ASP.NET Core 2.2 Web API project (so nothing to do with MVC Razor Pages or an UI). I have been following this Microsoft guide Account confirmation and password recovery in ASP.NET Core but obviously adapted it for my Web API project which consists of the following four endpoints: CreateUserAsync ConfirmEmailAsync PasswordResetEmailAsync ResetPasswordAsync Names are pretty self-explanatory the first two endpoints deal with creating a user,

问题 I have a Seam application that have to use an external one to login. The logic is as follows: My app sends user to external SSO URL User does what it takes to authenticate there On success, the external app redirects user back to my app with a random token My code should contact the external app via HTTP with the passed token and get complete user information in return Pretty straightforward. But I'm stuck. The redirect is coming to /seam/resources/token. I intended to get Identity from the

问题 As a follow-up to a previous question where I asked for a solution to a broken problem, I'm trying to find a way to express an arbitrary identifier in a "readable" way. Context: we are working with entities (domain model objects from DDD), which have an identity . This identity (mapped to a database primary key) can be expressed as a string: '123' , 'ABC' . Some entities can have a compound identity , i.e. composed of two or more other entities' identity : array('123','ABC') . Sometimes, we

问题 I am using this code for login. How can I find a user role when user login? [HttpPost] [AllowAnonymous] [ValidateAntiForgeryToken] public async Task<ActionResult> Login(LoginViewModel model, string returnUrl) { if (!ModelState.IsValid) { return View(model); } var user = await UserManager.FindByNameAsync(model.Username); if (user != null) { if (!await UserManager.IsEmailConfirmedAsync(user.Id)) { ViewBag.errorMessage = "You must have a confirmed email to log on."; return View("Error"); } } var

问题 We have to modify our database and manage the IDENTITY column ourselves (rather than relying on an auto-inc field). Our solution is to have a "Generator" table, which has an auto-inc field. We insert to this table and then read the SCOPE_IDENTITY value to get our new ID, e.g. insert into NewIDEntity (CreationDate) select GetDate() select @EntityID = SCOPE_IDENTITY() We are mainly concerned with the following scenario: • Transaction 1 INSERTS into NewID and receives 101 as the new ID to insert

问题 We are building a web application and right now we are in the stage of deciding how to keep track of our users. Our default option is to maintain our own user registration system which is a lot of headache (user name uniqueness, registration process, etc...). As an alternative we can use people's Facebook identity, meaning they will log in to our system using their Facebook's email and password. Then our back-end will fetch the user's Facebook id (Graph id), and store it in the DB. Any data

问题 Given a table: CREATE TABLE [GENERIC_TABLE] ( [RECORD_ID] [int] IDENTITY(1,1) NOT NULL, [SHORT_DESC] [varchar] (50) NULL, CONSTRAINT [PK_GENERIC_TABLE] PRIMARY KEY CLUSTERED ... I want to INSERT a record and get the value of the new RECORD_ID into a ColdFusion variable. What should my CFQUERY look like? (Admittedly, this is probably an overly easy question. In my defense I am used to working with Oracle, not SQL Server.) This for ColdFusion 8, but version-neutral solutions are good. 回答1: If
