微信公众号开发(三)

自定义菜单开发

根据微信自定义菜单文档，创建、删除自定义菜单只要向微信post一个请求就可以了

创建自定义菜单

请求的url: https://api.weixin.qq.com/cgi-bin/menu/create?access_token=ACCESS_TOKEN

请求参数(json格式):

{
 "button":[
 {    
      "type":"click",
      "name":"今日歌曲",
      "key":"feng_01"
  },
  {
       "name":"菜单",
       "sub_button":[
       {    
           "type":"view",
           "name":"搜索",
           "url":"http://www.baidu.com/"
        },
        {
           "type":"view",
           "name":"视频",
           "url":"http://v.qq.com/"
        },
        {
           "type":"click",
           "name":"赞一下我",
           "key":"feng_02"
        }]
   }]
}

这串json我是放在一个txt文件里，直接读取的。

发起请求:

public static void createWxMenu() {
    try {
        File file = new File("C:/Users/feng/Desktop/1.txt");
        if (file.isFile() && file.exists()) {
            FileInputStream in = new FileInputStream(file); 
            //微信只接受UTF-8的格式
            BufferedReader br = new BufferedReader(new InputStreamReader(in, "UTF-8"));
            StringBuffer sb = new StringBuffer();
            String lineTxt = null;
            while ((lineTxt = br.readLine()) != null) {
                sb.append(lineTxt); 
            }
            in.close();
            br.close();
            
            NetUtil.httpPost(action, sb.toString());
        } else {
            System.out.println("找不到指定的文件");
        }
    } catch (Exception e) {
        System.out.println("读取文件内容出错");
        e.printStackTrace();
    }
}

http方法

public static String httpPost(String reqUrl, String reqData){
    HttpURLConnection conn = null;
    OutputStream os = null;
    
    try {
        conn = (HttpURLConnection) new URL(reqUrl).openConnection();
        conn.setRequestMethod("POST");
        conn.setDoInput(true);
        conn.setDoOutput(true);
        conn.setReadTimeout(15*1000);
        conn.setConnectTimeout(5*1000);
        conn.setRequestProperty("accept", "*/*");
        conn.setRequestProperty("connection", "Keep-Alive");
        conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
        
        os = conn.getOutputStream();
        os.write(reqData.getBytes("UTF-8"));
        System.out.println("req:"+reqData);
        
        int responseCode = conn.getResponseCode();
        if(responseCode == HttpURLConnection.HTTP_OK){
            String resptxt = toString(conn.getInputStream());
            System.out.println(resptxt);
            return resptxt;
        }else{
            System.out.println("连接失败");
        }
    }catch(Exception e){
        System.out.println("连接异常:"+e.getMessage());
        e.printStackTrace();
    }finally{
        if (os != null)
            try {
                os.close();
            } catch (Exception e) {
            }

        if (conn != null)
            conn.disconnect();
    }
    return null;
}

调用结果：

查看微信, 没有问题

而菜单的详细设置请查看微信的文档，更改json就可以了，还有注意的一点就是这里的创建是以替换的形式执行的，它会把之前的菜单都去掉后再创建。

删除自定义菜单

请求url: https://api.weixin.qq.com/cgi-bin/menu/delete?access_token=ACCESS_TOKEN
