How to implement user subscription and push functions of the website through Webman

Webman is a powerful Web development framework that provides a wealth of functions and components, making We can build all types of websites and applications with ease. One of the important functions is the user subscription and push function. Through this function, we can send notifications, news, activities and other information to users to improve user stickiness and user experience.

This article will introduce how to implement the user subscription and push functions of the website through Webman, and attach the corresponding code examples.

First, we need to create a user subscription interface to receive user subscription requests. In the Webman framework, we can use the @Post annotation to create an interface. The sample code is as follows:

@Post("/subscribe")
public Result subscribe(@Body SubscriptionRequest request) {
    // 处理用户的订阅请求
    // 将用户信息保存到数据库或者推送服务商的平台上
    // 返回订阅成功的结果
    return Results.ok("订阅成功");
}

In the above code, we use the @Post annotation to An interface for POST requests is created with the path /subscribe. The parameter of the interface is a SubscriptionRequest object, used to receive the user's subscription information. According to actual needs, we can save the user's subscription information in the database or directly call the push service provider's interface to add the user to the subscription list.

Next, we need to create a push interface to send information to subscribed users. In the Webman framework, we can use the @Get annotation to create an interface. The sample code is as follows:

@Get("/push")
public Result push() {
    // 查询已经订阅的用户列表
    List<User> userList = userService.getAllSubscribedUsers();

    // 遍历用户列表，向每个用户发送推送消息
    for (User user : userList) {
        pushService.pushMessage(user, "这是一条推送消息");
    }

    // 返回推送成功的结果
    return Results.ok("推送成功");
}

In the above code, we use the @Get annotation to An interface for GET requests is created with the path /push. In the interface, we first query the subscribed user list, then traverse the user list, and call the pushMessage method of pushService to send push messages to each user.

In actual use, we can use a third-party push service provider to push messages. In this sample code, we assume that pushService is a tool class that encapsulates a third-party push service provider. You can select an appropriate push service provider based on specific needs and configurations.

Finally, we need to provide the user's subscription entrance and push button on the front-end page. In the Webman framework, we can use the Thymeleaf template engine to quickly build pages. The sample code is as follows:

<html>
<head>
    <script src="http://cdn.bootcss.com/jquery/2.1.4/jquery.min.js"></script>
</head>
<body>
    <h1>用户订阅和推送功能演示</h1>
    <form id="subscribeForm" action="/subscribe" method="post">
        <input type="email" name="email" placeholder="请输入邮箱">
        <button type="submit">订阅</button>
    </form>
    <button id="pushBtn">推送</button>
    
    <script type="text/javascript">
        $(document).ready(function() {
            // 监听订阅表单的提交事件
            $("#subscribeForm").submit(function(e) {
                e.preventDefault();

                // 发送订阅请求
                $.ajax({
                    url: "/subscribe",
                    type: "POST",
                    data: $("#subscribeForm").serialize(),
                    success: function(data) {
                        alert(data);
                    }
                });
            });

            // 监听推送按钮的点击事件
            $("#pushBtn").click(function() {
                // 发送推送请求
                $.ajax({
                    url: "/push",
                    type: "GET",
                    success: function(data) {
                        alert(data);
                    }
                });
            });
        });
    </script>
</body>
</html>

In the above code, we use the jQuery library to simplify front-end development. When the user clicks the subscribe button, a POST request will be sent to the /subscribe interface, and the data in the form will be serialized as the requested data. When the user clicks the push button, a GET request will be sent to the /push interface. In the success callback of the request, we use the alert method to display the returned result.

Through the above code examples, we can easily implement the user subscription and push functions of the website through Webman. Users can subscribe to the website by filling in their email address, and then we can send push messages to already subscribed users by clicking the push button. This function can be used to push news, events, offers and other information to improve user stickiness and user experience.
