Troubleshooting
Ok Response arrives but content is missing
Problem
We try to consume a value from a Web API method from Blazor. The Response has the Ok status, but the content is always null even though we are sure that we are indeed sending a content back.
Here is an example of such a scenario (of course there are many ways Blazor can consume a Web API):
Lets say we want to get a result of the following type from a Web API method:
public class SomeClass
{
public string Content;
}
Our Web API method which we want to consume from the Blazor side looks something like this:
[HttpGet]
[Route("SomeMethod")]
public ActionResult<SomeClass> SomeMethod()
{
var pi= new SomeClass{ Content = "Some content to be consumed." };
return Ok(pi);
}
And on the Blazor side we want to consume that Web API with a call like this:
var someObject = await Http.GetFromJsonAsync<SomeClass>("/api/SomeController/SomeMethod");
The result is received normally but for some reason the Content-Property is always null.
Potential Resolution
The class of the returned result must have its properties declared properly!
public class SomeClass
{
public string Content {get; set;}
}
