WEB API

Hi, anyone know how to make Input Validation in Web API? Data annotations do not work; I want to make it like in MVC [Required] or [RegularExpression] attributes. Any ideas?

I made something like this, but it's not working.

Hello, I have read this post Upload or Send File in Postman but now I want to add authorization token also, before sending request in Postman? So how can I add authorization header in postman? I have generated token using simply GET request.

I seriously ask this question.

Books for networking/security I purchased yesterday:

• Kurose Ross, top down approach
• Douglas Comer Internetworking with TCP/IP
• Udit Agrawal Computer Network

I'm planning to buy

• Fourouzan Networks
• Atul Kahate Network Security
• Fourouzan network security

I'm wondering what books/courses are actually good and worth purchasing? Please recommend. I'm a backend developer. I don't need language specific books. I love textbooks.
