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;
    }

}  

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。\n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;
    }

}

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;
    }

}  

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;
    }    

}

1.3.1 图片消息——ImgMessage

package com.ray.pojo.message.send;  

/**
 * 图片消息
 * @author shirayner
 *
 */
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;
    }

}  

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;
    }

}  

1.3.3 文件消息——FileMessage

package com.ray.pojo.message.send;  

/**
 * 文件消息
 * @author shirayner
 *
 */
public class FileMessage extends BaseMessage {
    //文件
    private Media file ;
    //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 getFile() {
        return file;
    }
    public void setFile(Media file) {
        this.file = file;
    }
    public int getSafe() {
        return safe;
    }
    public void setSafe(int safe) {
        this.safe = safe;
    }

}  

1.4  视频消息——Video、VideoMessage

Video.java

package com.ray.pojo.message.send;

/**
 * 视频
 * @author shirayner
 *
 */
public class Video {
    //是     视频媒体文件id，可以调用上传临时素材接口获取
    private String media_id;
    //否     视频消息的标题，不超过128个字节，超过会自动截断
    private String title;
    //否     视频消息的描述，不超过512个字节，超过会自动截断
    private String description;

    public String getMedia_id() {
        return media_id;
    }
    public void setMedia_id(String media_id) {
        this.media_id = media_id;
    }
    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;
    }    

}

VideoMessage.java

package com.ray.pojo.message.send;  

/**
 * 视频消息
 * @author shirayner
 *
 */
public class VideoMessage extends BaseMessage {
    //视频
    private Video video ;
    //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 Video getVideo() {
        return video;
    }
    public void setVideo(Video video) {
        this.video = video;
    }
    public int getSafe() {
        return safe;
    }
    public void setSafe(int safe) {
        this.safe = safe;
    }

}  

1.5 文本卡片消息——Textcard、TextcardMessage

Textcard.java

package com.ray.pojo.message.send;

/**
 * 文本卡片
 * @author shirayner
 *
 */
public class Textcard {
    //是 标题，不超过128个字节，超过会自动截断
    private String title;
    //是    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;
    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;
    }    

}

TextcardMessage.java

package com.ray.pojo.message.send;  

/**
 * 文本卡片消息
 * @author shirayner
 *
 */
public class TextcardMessage extends BaseMessage {
    //文本
    private Textcard textcard;

    //btntxt    否    按钮文字。 默认为“详情”， 不超过4个文字，超过自动截断。

    public Textcard getTextcard() {
        return textcard;
    }

    public void setTextcard(Textcard textcard) {
        this.textcard = textcard;
    }

}  

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;
    }    

}

News.java

package com.ray.pojo.message.send;

import java.util.List;

/**
 * 图文
 * @author shirayner
 *
 */
public class News {
     //文章列表
     private List<Article> articles;

    public List<Article> getArticles() {
        return articles;
    }

    public void setArticles(List<Article> articles) {
        this.articles = articles;
    }

}

NewsMessage.java

package com.ray.pojo.message.send;  

/**
 * 图文消息
 * @author shirayner
 *
 */
public class NewsMessage extends BaseMessage {
    //图文
    private News news;

    public News getNews() {
        return news;
    }

    public void setNews(News news) {
        this.news = news;
    }

}
