## 微信发送模板消息与生成自己公众号二维码 ##

### 1 发送模板消息 ###

前置条件参考：  
①注册测试账号  
②开通自己的测试公众号  
③完成与微信互发消息  
④完成自定义菜单栏  
⑤获取自己的accessToken

#### 1.1 在公众号平台新增模板消息 ####

①需要查看模板消息运营规范：https://developers.weixin.qq.com/doc/offiaccount/Message\_Management/Template\_Message\_Operation\_Specifications.html

下载附件，在附件中找到允许的模板消息

> 下载附件之后，打开word可以知道支持的模板消息，此处我选择的是简历反馈

#### 1.2 设置所属的行业 ####

> 每次发送请求都需要携带accessToken

此处我使用实体类封装json数据  
AccessToken ：

@Data
    @NoArgsConstructor
    @AllArgsConstructor
    public class AccessToken {
        
    
        private String access_token;
    
        //过期时间
        private long expires_time;
    
        public AccessToken(String access_token, Integer expires_in){
        
            this.access_token = access_token;
            expires_time = System.currentTimeMillis() + expires_in * 1000;
        }
    
        public boolean isExpire(){
        
            return System.currentTimeMillis() > expires_time;
        }
    }

在service中获取accessToken：

/**
     * 获取accessToken
     *
     * @return
     */
    public AccessToken getAccessToken() {
        
        String APPID = wxConfig.getAppId();
        String SECRET = wxConfig.getSecret();
        //拼接url【传入appId和secret】
        url = url.replace("APPID", APPID).replace("APPSECRET", SECRET);
        OkHttpClient client = new OkHttpClient();
        //构建请求
        Request request = new Request.Builder().url(url).build();
        Call call = client.newCall(request);
        Response response = null;
        try {
        
            //获取响应体
            response = call.execute();
            //{"access_token":"ACCESS_TOKEN","expires_in":7200} 返回体类型
            if (response != null) {
        
                ResponseBody body = response.body();
                String bodyStr = body.string();
                JSONObject jsonObject = JSONObject.parseObject(bodyStr);
                //获取过期时间
                String access_token = (String) jsonObject.get("access_token");
                Integer expires_in = (Integer) jsonObject.get("expires_in");
                AccessToken accessToken = new AccessToken(access_token, expires_in);
                return accessToken;
            }
        } catch (IOException e) {
        
            e.printStackTrace();
        }
        return null;
    }

/**
     * 设置所属行业
     */
    @Test
    public void setIndustry() throws IOException {
        
        String url = "https://api.weixin.qq.com/cgi-bin/template/api_set_industry?access_token=ACCESS_TOKEN";
        //获取accessToken
        AccessToken accessToken = wxService.getAccessToken();
        String access_token = accessToken.getAccess_token();
        url = url.replaceAll("ACCESS_TOKEN", access_token);
        //设置五秒超时
        OkHttpClient client = new OkHttpClient.Builder().readTimeout(5, TimeUnit.SECONDS).build();
        String json = "{\n" +
                "    \"industry_id1\":\"1\",\n" +
                "    \"industry_id2\":\"2\"\n" +
                "}";
        //请求体【发送json数据】
        RequestBody body = RequestBody.create(MediaType.parse("application/json"), json);
        //构建请求
        Request request = new Request.Builder()
                .url(url)
                .post(body)
                .build();
        Call call = client.newCall(request);
        //发起请求
        Response response = call.execute();
        Assert.assertEquals(response.code(), 200);
    }

可以测试自己所设置的行业信息：

/**
     * 获取设置的行业信息
     */
    @Test
    public void getIndusInfo() throws IOException {
        
        String url = "https://api.weixin.qq.com/cgi-bin/template/get_industry?access_token=ACCESS_TOKEN";
        //获取accessToken
        AccessToken accessToken = wxService.getAccessToken();
        String access_token = accessToken.getAccess_token();
        url = url.replaceAll("ACCESS_TOKEN", access_token);
        OkHttpClient client = new OkHttpClient.Builder().readTimeout(5, TimeUnit.SECONDS).build();
        Request request = new Request.Builder()
                .url(url)
                .get()
                .build();
        //发起请求
        Call call = client.newCall(request);
        Response response = call.execute();
        String responseStr = response.body().string();
        System.out.println(responseStr);
        //{"primary_industry":{"first_class":"IT科技","second_class":"互联网|电子商务"},
        // "secondary_industry":{"first_class":"IT科技","second_class":"IT软件与服务"}}
    }

#### 1.3 发送模板消息 ####

> 注意，严格来说应该使用类来封装json数据，此处我为了简便，就没有封装

/**
     * 发送模板消息
     */
    @Test
    public void sendTemplateMsg() throws IOException {
        
        OkHttpClient client = new OkHttpClient.Builder().readTimeout(5, TimeUnit.SECONDS).build();
        String url = "https://api.weixin.qq.com/cgi-bin/message/template/send?access_token=ACCESS_TOKEN";
        AccessToken accessToken = wxService.getAccessToken();
        String access_token = accessToken.getAccess_token();
        url = url.replace("ACCESS_TOKEN", access_token);
        String json = "{\n" +
                "   \"touser\":\"oMKoX6L_Ee7Svjku5wSY4BhYQlk0\",\n" +

                "   }\n" +
                "}";
        RequestBody body = RequestBody.create(MediaType.parse("application/json"), json);
        //构建请求
        Request request = new Request.Builder()
                .url(url)
                .post(body)
                .build();
        Call call = client.newCall(request);
        Response response = call.execute();
        System.out.println(response.body().string());
    }

#### ①获取自己的ticket ####

直接在controller中编写逻辑

@PostMapping("/getQr")
    public String getQr(){
        
        String url = "https://api.weixin.qq.com/cgi-bin/qrcode/create?access_token=TOKEN";
        //获取accessToken
        AccessToken accessToken = wxService.getAccessToken();
        String access_token = accessToken.getAccess_token();
        url = url.replaceAll("TOKEN", access_token);
        OkHttpClient client = new OkHttpClient.Builder().readTimeout(5, TimeUnit.SECONDS).build();
        String json = "{\"expire_seconds\": 600, \"action_name\": \"QR_STR_SCENE\", \"action_info\": {\"scene\": {\"scene_str\": \"testQr\"}}}";
        RequestBody body = RequestBody.create(MediaType.parse("application"), json);
        Request request = new Request.Builder()
                .url(url)
                .post(body)
                .build();
        Call call = client.newCall(request);
        Response response = null;
        try {
        
            response = call.execute();
            String responseStr = response.body().string();
            JSONObject jsonObject = JSONObject.parseObject(responseStr);
            String ticket = (String) jsonObject.get("ticket");
            System.out.println("ticket:" + ticket);
            return ticket;
        } catch (IOException e) {
        
            e.printStackTrace();
        }
        return "";
    }

#### ②前端拼接显示 ####

<!DOCTYPE html>
    <html lang="en" xmlns:th="http://www.thymeleaf.org">
    <head>
        <meta charset="UTF-8">
        <title>Title</title>
    </head>
    <script src="jquery-3.4.1.min.js"></script>
    <script>
        function getQr(){
          
            var url = "getQr";
            $.post(url, function (ticket){
          
                var src = "https://mp.weixin.qq.com/cgi-bin/showqrcode?ticket="+ticket;
                $("img").attr("src", src);
            });
        }
    </script>
    <body>
        <button type="submit" onclick="getQr()">点击获取Qr</button>
        <img src="" alt="">
    </body>
    </html>
