如何在JS中传递C#变量

// Controllers/MyController.cs
[HttpGet("api/data")]
public IActionResult GetData()
{
    string myVariable = "Hello from C#!";
    return Ok(myVariable);
}

fetch('/api/data')
    .then(response => response.json())
    .then(data => {
        console.log(data); // 输出: Hello from C#!
    });

@{
    string myVariable = "Hello from C#!";
}

<script>
    var jsVariable = '@myVariable';
    console.log(jsVariable); // 输出: Hello from C#!
</script>

// Hubs/DataHub.cs
public class DataHub : Hub
{
    public string GetData()
    {
        return "Hello from C#!";
    }
}

const connection = new signalR.HubConnectionBuilder()
    .withUrl("/dataHub")
    .build();

connection.start().then(() => {
    connection.invoke("GetData").then(data => {
        console.log(data); // 输出: Hello from C#!
    });
});
