  • Java企业微信开发_04_消息推送之发送消息(主动)

     源码请见: Java企业微信开发_00_源码及资源汇总贴

    一、本节要点

    1.发送消息与被动回复消息

    (1)流程不同:发送消息是第三方服务器主动通知微信服务器向用户发消息。而被动回复消息是 用户发送消息之后,微信服务器将消息传递给 第三方服务器,第三方服务器接收到消息后,再对消息做出相应的回复消息。

    (2)消息是否加密:在发送消息的流程中,对封装好的回复消息(json字符串)是不进行AES加密的。

                                      而在被动回复消息的流程中,第三方服务器接收消息时,需要先解密微信发过来的消息,在最后发送回复消息前,需要先加密(AES)回复消息。

    (3)数据交换的格式不同:在发送消息的流程中,第三方服务器将消息(json字符串格式)发送给微信服务器

                                                 而在被动回复消息的过程中,第三方服务器接收的消息和被动回复的消息都是以xml字符串格式的。

    二、代码实现

    1.实体类

    1.1 消息基类(企业号 -> 普通用户) ——BaseMessage

    package com.ray.pojo.message.send;  
      
    /**
     * 消息基类(企业号 -> 普通用户) 
     * @author shirayner
     *
     */
    public class BaseMessage {  
        // 否 成员ID列表(消息接收者,多个接收者用‘|’分隔,最多支持1000个)。特殊情况:指定为@all,则向该企业应用的全部成员发送
        private String touser;  
        // 否 部门ID列表,多个接收者用‘|’分隔,最多支持100个。当touser为@all时忽略本参数
        private String toparty;  
        // 否 标签ID列表,多个接收者用‘|’分隔,最多支持100个。当touser为@all时忽略本参数
        private String totag;  
        // 是 消息类型 
        private String msgtype; 
        // 是 企业应用的id,整型。可在应用的设置页面查看
        private int agentid;
        
        
        public String getTouser() {
            return touser;
        }
        public void setTouser(String touser) {
            this.touser = touser;
        }
        public String getToparty() {
            return toparty;
        }
        public void setToparty(String toparty) {
            this.toparty = toparty;
        }
        public String getTotag() {
            return totag;
        }
        public void setTotag(String totag) {
            this.totag = totag;
        }
        public String getMsgtype() {
            return msgtype;
        }
        public void setMsgtype(String msgtype) {
            this.msgtype = msgtype;
        }
        public int getAgentid() {
            return agentid;
        }
        public void setAgentid(int agentid) {
            this.agentid = agentid;
        }
    
        
     
        
        
    }  
    View Code

    1.2 文本消息——Text、TextMessage

    企业微信官方文档中关于文本消息请求包的说明

    {
       "touser" : "UserID1|UserID2|UserID3",
       "toparty" : " PartyID1|PartyID2 ",
       "totag" : " TagID1 | TagID2 ",
       "msgtype" : "text",
       "agentid" : 1,
       "text" : {
           "content" : "你的快递已到,请携带工卡前往邮件中心领取。
    出发前可查看<a href="http://work.weixin.qq.com">邮件中心视频实况</a>,聪明避开排队。"
       },
       "safe":0
    }

    可把整个json对象看做一个java对象,而在这个json对象中又包含一个text对象。(json中的对象用{ }包裹起来,json中的数组用[  ] 包裹起来

    需注意agentid、safe为int型。于是可以把text看做一个java对象,这样TextMessage类组合了Text类,转json字符串的时候,就可以直接使用 String jsonTextMessage=gson.toJson(textMessage).

    于是,我们开始对文本消息进行封装

    Text.java

    package com.ray.pojo.message.send;
    
    /**
     * 文本
     * @author shirayner
     *
     */
    public class Text {
        //是    消息内容,最长不超过2048个字节
        private String content;
    
        public String getContent() {
            return content;
        }
    
        public void setContent(String content) {
            this.content = content;
        }
    
    
    
    }
    View Code

    TextMessage.java

    package com.ray.pojo.message.send;  
      
    /**
     * 文本消息
     * @author shirayner
     *
     */
    public class TextMessage extends BaseMessage {  
        //文本
        private Text text;
        //否     表示是否是保密消息,0表示否,1表示是,默认0
        private int safe;
        
        public Text getText() {
            return text;
        }
        public void setText(Text text) {
            this.text = text;
        }
        public int getSafe() {
            return safe;
        }
        public void setSafe(int safe) {
            this.safe = safe;
        }
        
        
      
       
    }  
    View Code

    1.3 图片类、语音类、文件类——Media

    通过对微信官方文档的仔细阅读,可以看到图片消息、语音消息、文件消息中的的json对象都内含同一个Jason对象(media_id),于是我们根据这个对象封装Media.java

    package com.ray.pojo.message.send;
    
    /**
     * 图片、语音、文件
     * @author shirayner
     *
     */
    public class Media {
        //是     图片/语音/文件 媒体文件id,可以调用上传临时素材接口获取
        private String media_id;
    
        public String getMedia_id() {
            return media_id;
        }
    
        public void setMedia_id(String media_id) {
            this.media_id = media_id;
        }    
        
        
    }
    View Code

    public class ImgMessage extends BaseMessage {  
        //图片
        private Media image ;
        //否     表示是否是保密消息,0表示否,1表示是,默认0
        private int safe;
        
        public Media getImage() {
            return image;
        }
        public void setImage(Media image) {
            this.image = image;
        }
        public int getSafe() {
            return safe;
        }
        public void setSafe(int safe) {
            this.safe = safe;
        }
    
       
    }  
    View Code

    1.3.2 语音消息——VoiceMessage

    package com.ray.pojo.message.send;  
      
    /**
     * 语音消息
     * @author shirayner
     *
     */
    public class VoiceMessage extends BaseMessage {  
        //语音
        private Media voice ;
        //否     表示是否是保密消息,0表示否,1表示是,默认0
        private int safe;
        
        public Media getVoice() {
            return voice;
        }
        public void setVoice(Media voice) {
            this.voice = voice;
        }
        public int getSafe() {
            return safe;
        }
        public void setSafe(int safe) {
            this.safe = safe;

            return file;
        }
        public void setFile(Media file) {
            this.file = file;
        }
        public int getSafe() {

        }
       
        
    
       
    }

    1.4  视频消息——Video、VideoMessage

    Video.java

    package com.ray.pojo.message.send;
    
    /**
     * 视频
     * @author shirayner

     */
    public class Video {

    1.5 文本卡片消息——Textcard、TextcardMessage

        //是    点击后跳转的链接。
        private String url;
        public String getTitle() {
            return title;
        }
        public void setTitle(String title) {
            this.title = title;
        }
        public String getDescription() {
            return description;
        }
        public void setDescription(String description) {
            this.description = description;
        }
        public String getUrl() {
            return url;

    1.6 图文消息——Article、News、NewsMessage

    企业微信官方文档中关于图文消息请求包的说明:

    {
       "touser" : "UserID1|UserID2|UserID3",
       "toparty" : " PartyID1 | PartyID2 ",
       "totag" : " TagID1 | TagID2 ",
       "msgtype" : "news",
       "agentid" : 1,
       "news" : {
           "articles" : [
               {
                   "title" : "中秋节礼品领取",
                   "description" : "今年中秋节公司有豪礼相送",
                   "url" : "URL",
                   "picurl" : "http://res.mail.qq.com/node/ww/wwopenmng/images/independent/doc/test_pic_msg1.png"
               }
            ]
       }
    }

    可以看到NewsMessage类组合了News类,News类组合了List<Aticle> articles(即Article数组),于是得到以下实体类。

    Article.java

    package com.ray.pojo.message.send;
    
    /**
     * 文章
     * @author shirayner
     *

    public class Article {
        //是    标题,不超过128个字节,超过会自动截断
        private String title;    
        //否    描述,不超过512个字节,超过会自动截断
        private String description;    
        //是    点击后跳转的链接。
        private String url;    
        //否    图文消息的图片链接,支持JPG、PNG格式,较好的效果为大图640320,小图8080。
        private String picurl;
        public String getTitle() {
            return title;
        }
        public void setTitle(String title) {
            this.title = title;
        }
        public String getDescription() {
            return description;
        }
        public void setDescription(String description) {
            this.description = description;
        }
        public String getUrl() {
            return url;
        }
        public void setUrl(String url) {
            this.url = url;
        }
        public String getPicurl() {
            return picurl;
        }
        public void setPicurl(String picurl) {
            this.picurl = picurl;
