Return a JSON string explicitly from Asp.net WEBAPI?

Question

In Some cases I have NewtonSoft JSON.NET and in my controller I just return the Jobject from my controller and all is good.

But I have a case where I get some raw JS

Answer 1

This works for me in .NET Core 3.1.

private async Task ChannelCosmicRaysAsync(HttpRequestMessage request)
{
    // client is HttpClient
    using var response = await client.SendAsync(request).ConfigureAwait(false); 

    var responseContentString = await response.Content.ReadAsStringAsync().ConfigureAwait(false);

    Response.StatusCode = (int)response.StatusCode;
    return Content(responseContentString, "application/json");
}

public Task X()
{
    var request = new HttpRequestMessage(HttpMethod.Post, url);
    (...)

    return ChannelCosmicRaysAsync(request);
}

ContentResult is Microsoft.AspNetCore.Mvc.ContentResult.

Please note this doesn't channel headers, but in my case this is what I need.
