Applet page generation link sent by SMS

One 、 background

         There is an activity page that needs to send the page link through SMS , There is a official account QR code in the link , Users can scan the enterprise wechat QR code to add teachers to receive information .

Two 、 Implementation analysis

analysis ： Because it is an enterprise wechat QR code, you need to open it in wechat . After initial analysis, the implementation methods may include the following ：

1. Click the activity page link in the SMS and pull up wechat , Then open it on wechat H5 page . Put the enterprise wechat QR code in the page, and then long press the user to identify .
2. Click the link of the activity page in the SMS to pull up the wechat applet , You can jump in the applet h5, Then users can long press the QR code to identify enterprise wechat .

After analyzing the first method, no implementation scheme is found , The second kind of applet is officially given three implementation methods ：

adopt URL Scheme Realization

Through the server interface or in the background of applet management URL Scheme after , Self developed transit H5 page .

Will have transit H5 The linked SMS content is delivered through the developer's own SMS sending ability or the service provider's SMS service , Realize SMS open applet .

adopt URL Link Realization

Generate through the server interface URL Link.

Directly with URL Link The SMS content of is delivered through the developer's own SMS sending ability or the SMS service of the service provider , Realize SMS open applet .

Through cloud development static website

You can refer to 「 Development of cloud 」-「 Static website 」-「 SMS jump applet 」.

After analysis, it is decided to adopt pass url link To achieve .

3、 ... and 、 Business implementation

1. First, develop a H5 The page will contain the two-dimensional code of enterprise wechat on h5 On the page .

This page only needs to follow UI The design can be developed normally .

2. Put the page into the applet

Create a new page in the applet , And then use web-view Tag nesting h5 page

  At this time, the applet page is as follows ：

3. Generate the current applet page according to the document url link.

At this time, the page path is “pages/index/index”

Generate according to the official documentation URL Link

    public static String getAccessToken(String appId,String appSecret) {
        String token = null;
        Lock lock = new ReentrantLock();
        lock.lock();
        try {
            String requestTokenUrl = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=APPID&secret=SECRET";
            requestTokenUrl = requestTokenUrl.replace("APPID", appId);

            if(parse != null && StringUtils.isNotBlank(parse.getAccess_token())){

            }
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            lock.unlock();
        }
        return  token;
    }




public static void main(String[] args) {
        String accessToken = getAccessToken(WxtkConfig.LIVE_APP_ID, WxtkConfig.LIVE_APP_SECRET);
        String requestUrl = URL_LINK_GENE_URL.replace("ACCESS_TOKEN",accessToken);
        Map<String,Object> map = new HashMap<>();
        map.put("path","pages/index/index");
        map.put("query","");
        map.put("env_version","release");
        map.put("is_expire",true);
        map.put("expire_type",1);
        map.put("expire_interval",180);
        // Need to introduce hutool Package or package one by yourself http Request tool class is also ok 
        String post = HttpUtil.post(requestUrl, JsonUtils.serialize(map));
        System.out.println("post = " + post);
    }

After the request is successful, it will return url route , Then put the path into the SMS template and send it .

4. Put the... Of the applet page url link Put it in the SMS template , Then call the template to send .

OK. The above is the whole realization idea . Those who have better ideas or ideas can add wechat communication
