Zoho Catalyst登出页面报错：ReferenceError: Catalyst未定义

部署在Zoho Catalyst上的网页实现登出功能时，出现如下错误：

ReferenceError: Catalyst is not defined at logout.html:17:24

用户的原代码如下：

<!DOCTYPE html>
<html lang="es">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Cierre de Sesión</title>
</head>
<body>
    <table>
        <tr>
            <td><a class="boton" id="cerrar-sesion" href="#">Cerrar Sesión</a></td>
        </tr>
    </table>

    <script src="https://static.zohocdn.com/catalyst/sdk/js/4.0.0/catalystWebSDK.js"></script>
    <script>
        var catalyst = new Catalyst({
            projectID: 'project_ID',
            clientID: 'Client_ID',
            clientSecret: 'Client_Secret'
        });

        catalyst.init();

        function cerrarSesion(event) {
            event.preventDefault();
            var redirectURL = "https://redirect-url.com/baas/logout?logout=true&PROJECT_ID=my_project_ID";
";
            catalyst.auth.signOut(redirectURL)
            .then(function() {
                console.log("Sesión cerrada correctamente");
                window.location.href = redirectURL;
            })
            .catch(function(error) {
                console.error("Error al cerrar sesión:", error);
            });
        }

        document.addEventListener("DOMContentLoaded", function() {
            document.getElementById("cerrar-sesion").addEventListener("click", cerrarSesion);
        });
    </script>
</body>
</html>

错误原因分析 #

• 构造函数名称错误：Zoho Catalyst Web SDK v4.x的全局构造函数是ZCatalyst，而非Catalyst，这是触发ReferenceError的核心原因。
• 语法错误：定义redirectURL时多了一行多余的";，会导致脚本解析中断。
• 安全隐患：Web端初始化SDK无需传入clientSecret，该密钥属于敏感信息，绝对不能暴露在前端代码中，官方Web SDK初始化仅需projectID和clientID。

修正后的代码 #

<!DOCTYPE html>
<html lang="es">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Cierre de Sesión</title>
</head>
<body>
    <table>
        <tr>
            <td><a class="boton" id="cerrar-sesion" href="#">Cerrar Sesión</a></td>
        </tr>
    </table>

    <script src="https://static.zohocdn.com/catalyst/sdk/js/4.0.0/catalystWebSDK.js"></script>
    <script>
        // 使用正确的ZCatalyst构造函数，移除敏感的clientSecret
        var catalyst = new ZCatalyst({
            projectID: 'project_ID',
            clientID: 'Client_ID'
        });

        catalyst.init();

        function cerrarSesion(event) {
            event.preventDefault();
            // 修复语法错误，移除多余的引号和分号
            var redirectURL = "https://redirect-url.com/baas/logout?logout=true&PROJECT_ID=my_project_ID";
            
            catalyst.auth.signOut(redirectURL)
            .then(function() {
                console.log("Sesión cerrada correctamente");
                window.location.href = redirectURL;
            })
            .catch(function(error) {
                console.error("Error al cerrar sesión:", error);
            });
        }

        document.addEventListener("DOMContentLoaded", function() {
            document.getElementById("cerrar-sesion").addEventListener("click", cerrarSesion);
        });
    </script>
</body>
</html>
