aspnetcore: Error when trying get data from real server

Hello,

I have issue with this code from demo:

@page "/fetchdata"
@inject HttpClient Http

@if (door == null)
{
    <p><em>Loading...</em></p>
}
else
{
    <table class='table'>
        <thead>
            <tr>
                <th>Id</th>
                <th>Name</th>
                <th>Version</th>
            </tr>
        </thead>
        <tbody>
            <tr>
                <td>@door.id</td>
                <td>@door.name</td>
                <td>@door.version</td>
            </tr>
        </tbody>
    </table>
}

@functions {
    Door door;

    protected override async Task OnInitAsync()
    {
        door = await Http.GetJsonAsync<Door>("http://localhost:58009/api/locations/1/doors/2");
    }

    class Door
    {
        public int id { get; set; }
        public int? locationId { get; set; }
        public string name { get; set; }
        public int strikeTime { get; set; }
        public int extendedAccessTime { get; set; }
        public int heldOpenTime { get; set; }
        public string version { get; set; }
    }
}

I’m getting error in browser console window:

SEC7120: Origin http://localhost:5375 not found in Access-Control-Allow-Origin header.

WASM: [System.Net.Http.HttpRequestException] TypeError: Failed to fetch

4 WASM: — End of stack trace from previous location where exception was thrown —

If I just simply request if in browser => “http://localhost:58009/api/locations/1/doors/2”, I get this json response: { “id”:2, “locationId”:1, “name”:“216office”, “strikeTime”:3, “extendedAccessTime”:6, “heldOpenTime”:10, “version”:“AAAAAAAAKMw=” }

It is possible that need setup header content type to “application/json”?
