codeigniter 404(页面未找到)

我正在集成Google Drive API，用于将文件从HTML表单上传到Google云端硬盘。当我在CorePHP中实现代码（ AJAX 和jQuery）时，它工作正常，但在CodeIgniter 4中不工作。问题是由于URL吗？
Web浏览器的控制台显示错误：
404upload.html?code=4/0AX4XfWgb3ql4RL2FfY7RdaL7jgyDOYT3CztsruXIbiLNdziDJKZ_UWFNK3qNzEgdcZrMFQ&scope=https://www.googleapis.com/auth/drive（页面未找到）
文件 index.html（用于登录Google帐户）：

<!DOCTYPE html>

<head>
    <meta charset="utf-8" />
    <meta http-equiv="X-UA-Compatible" content="IE=edge">

   <div>
       <button id="login">
           Upload Files to Drive
       </button>
   </div>
</body>
</html>

文件 main.js（重定向到 upload.html 以将文件上传到Google云端硬盘）：

$(document).ready(function() {

    // Client id of the project
    var clientId = "";

    // redirect_uri of the project
    var redirect_uri = "http://localhost:8080/upload.html";

    // Scope of the project
    var scope = "https://www.googleapis.com/auth/drive";

    // The URL to which the user is redirected to
    var url = "";

    // This is event click listener for the button
    $("#login").click(function() {

        // This is the method which will be invoked it takes four parameters

        signIn(clientId, redirect_uri, scope, url);
    });

    function signIn(clientId, redirect_uri, scope, url) {

        // The actual URL to which the user is redirected to
        url = "https://accounts.google.com/o/oauth2/v2/auth?redirect_uri=" + redirect_uri +
        "&prompt=consent&response_type=code&client_id=" + clientId + "&scope=" + scope +
        "&access_type=offline";T

        // This line makes the user redirected to the URL
        window.location = url;
    }
});

我是新来的代码点火器4。

如果服务器无法找到请求的资源，通常会收到 404 Not Found 响应。
HTTP 404
HTTP 404，404 not found，404，404 error，page not found or file not found错误消息是计算机网络通信中的一个超文本传输协议（HTTP）标准响应代码，用于指示浏览器能够与给定服务器通信，但服务器无法找到所请求的内容。
在您的特定情况下，redirect_uri指向的GET /upload.html在您的路由文件（app\Config\Routes.php）中没有明确定义。

溶液

在路线文件中定义路线。即：
$routes->get("upload.html", "Home::upload");
其中第一个参数表示 URI，第二个参数表示响应的***Controller***：：方法。
您可以使用以下命令获取 * 控制器方法 * 中的查询参数：

// Sample route: http://localhost:8080/upload.html?code=4/0AX4XfWgb3ql4RL2FfY7RdaL7jgyDOYT3CztsruXIbiLNdziDJKZ_UWFNK3qNzEgdcZrMFQ&scope=https://www.googleapis.com/auth/drive

$params = $this->request->getGet();

/*
* Output.

[
  "code" => "4/0AX4XfWgb3ql4RL2FfY7RdaL7jgyDOYT3CztsruXIbiLNdziDJKZ_UWFNK3qNzEgdcZrMFQ",
 "scope" => "https://www.googleapis.com/auth/drive"
