I'm experimenting with Blazor WebAssembley (.Net 5), calling my rest web api (built a while ago using .netcore 2.0.0).
I am running the code against a debug version of the web service hence the localhost url on port 51259.
When the code gets hit I get an exception that I cannot understand:
Unhandled exception rendering component: TypeError: Failed to fetch
System.Net.Http.HttpRequestException: TypeError: Failed to fetch
I have setup CORS on the web service in the form of:
public void ConfigureServices(IServiceCollection services)
{
services.AddMvc();
services.AddCors(c =>
{
c.AddPolicy("AllowOrigin", options => options.AllowAnyOrigin().AllowAnyHeader().WithMethods("GET, PATCH, DELETE, PUT, POST, OPTIONS"));
});
}
Client side Blazor WebAssembley
@code {
private Models.MyFooObject fooObject = new Models.MyFooObject();
private async Task UpdateDatatheme()
{
//ERROR HERE
fooObject = await Http.GetFromJsonAsync<Models.MyFooObject("http://localhost:51259/service/myfooObject/0001");
}
Can anyone help - I'm out of ideas.
