向 API 执行“获取”请求时出现 404 错误

Question

Trying to perform a "get" request to API. I know the API will return the data when I do the "get" from Postman. So I believe the problem is with my HTML.尝试对 API 执行“获取”请求。我知道当我从 Postman 执行“获取”时，API 将返回数据。所以我相信问题出在我的 HTML 上。

<!DOCTYPE html>
<html>
<body>
    <h1>My First Heading</h1>
    <p>My first paragraph.</p>

        <script>
            const Http = new XMLHttpRequest();
            const url='https://localhost:44369';
            Http.open("GET", url);
            Http.send();

            Http.onreadystatechange = (e) => {
            console.log(Http.responseText)
            }

        </script>
</body>
</html>

Here's the API method I'm trying to "get" from:这是我试图从中“获取”的 API 方法：

    //https://localhost:44369/api/Request
    [EnableCors("AllowLocalhostOrigins")]
    [HttpGet]
    public ActionResult GetText()
    {
       string a = "b";

        return Ok(a);
    }

Here's the error I'm getting: 404 Not Found这是我收到的错误： 404 Not Found

Answer 1

After doing some more reading, I see that it's a problem with the API and not the html code I posted this question about.在做了更多阅读之后，我发现这是 API 的问题，而不是我发布此问题的 html 代码。 The html code I posted works fine.我发布的 html 代码工作正常。
