Part of: Pams

NuGet package dependency

System.Web.Http.Cors is a NuGet package dependency for the legacy ASP.NET Web API project in Pams.API. It enables the API to apply Cross-Origin Resource Sharing policies so browser clients from allowed origins can call HTTP endpoints.

Usage

ts
const response = await fetch("https://api.example.com/api/patients", {
  method: "GET",
  headers: {
    Accept: "application/json",
  },
});

if (!response.ok) {
  throw new Error(`API request failed: ${response.status}`);
}

const patients = await response.json();
console.log(patients);

AI Coding Instructions

• Treat System.Web.Http.Cors as a server-side dependency; browser code only sends requests with an Origin header.
• Configure allowed origins, methods, and headers in the ASP.NET Web API startup or route configuration.
• Keep CORS policy changes aligned with the client application's actual API origin.
• Check preflight OPTIONS requests when adding custom request headers or non-simple HTTP methods.
