Asp.net core webapi server to configure cross-origin instances, corewebapi
In the frontend and backend separation development, the server only provides api interfaces for the frontend, And the frontend and backend are usually deployed separately. In this case, cross-origin browser issues may occur. Asp.net core provides simple and elegant solutions.
Add the following code to Configure in the startup File (replace "http: // localhost: 8080" with your frontend deployment address. The frontend address tested here is the local port 8080)
Note: The nuget package must be installed below asp.net core2.0: Microsoft. AspNetCore. Cors
App. UseCors (builder ==>{ builder. AllowAnyHeader (); builder. AllowAnyMethod (); builder. WithOrigins ("http: // localhost: 8080 ");});
If you only need to replace builder in the development environment. withOrigins ("http: // localhost: 8080") is builder. allowAnyOrigins () allows cross-origin access from any source address (not recommended in the production environment)
