Recently, I was working on a project for a customer. The user asked the website to enable single-point login for domain users, instead of entering the user name and password for login. Obviously, the traditional website is set as a basic identity authentication (domain authentication), and the cancellation of anonymous authentication cannot meet the requirements.

To solve this problem we allow the user to set a expire value to avoid the problem of nonce authentication.3.

Four authentication programming methods of ASP. net mvc, asp. netmvc
We can use four different programming modes to verify the binding parameters.
1. Manually verify the bound parameters
When defining specific Action methods, manual verification of successfully bound parameters is undoubtedly the most direct programming method, next, we will use a simple example
Four authentication programming methods under ASP. net mvc, asp. netmvc
ASP. net mvc uses Model binding to generate a list of corresponding parameters for the target Action. However, before the actual execution of the target Action method, it is necessary to verify the bound parameters to ensure their effectiveness, we will verify the parameters as Model binding. In general, we can use four different progra

greatest impact on programming, not from the code, but from the ideological change, the "master-slave transposition" has occurred. The application was originally the boss, to get what resources are active attack, but in Ioc/di thought, the application becomes passive, passively wait for the Ioc/di container to create and inject the resources she needs. This action effectively separates the object from the external resources she needs, makes them loosely coupled, facilitates functional reuse, an
