When I try to fetch data from the UserController I get returned Html for some reason. It is the index.html file under the React > Public folder. It should be returning the Users from the UserController.

I have a React frontend app which I have added ASP.NET Core Web API backend.

============================Update===================================

Follow the tutorial you provide, and do the first 3 steps :

Then I get a solution within 2 projects(one react and one asp.net core 6 web api project)

Adding a controller with your code then I can access the api with url https://localhost:7119/api/user in the browser.

Modify the App.js file in the react project, adding the fetch method in the componentDidMount() function. Then start both the project.

CodePudding user response：

just fix your action route, API controller doesn't support any REST

[Route("~/api/user/getList")]
public ActionResult<IEnumerable<User>> List()

and make the same fetch route

htt.../api/user/getList
