Java发送企业微信应用消息

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

 1  
 2 /**
 3  * 消息基类(企业号 -> 普通用户) 
 4  * @author hh
 5  *
 6  */
 7 public class BaseMessage {  
 8     // 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
 9     private String touser;  
10     // 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
11     private String toparty;  
12     // 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
13     private String totag;  
14     // 是 消息类型 
15     private String msgtype; 
16     // 是 企业应用的id,整型。可在应用的设置页面查看
17     private int agentid;
18     
19     
20     public String getTouser() {
21         return touser;
22     }
23     public void setTouser(String touser) {
24         this.touser = touser;
25     }
26     public String getToparty() {
27         return toparty;
28     }
29     public void setToparty(String toparty) {
30         this.toparty = toparty;
31     }
32     public String getTotag() {
33         return totag;
34     }
35     public void setTotag(String totag) {
36         this.totag = totag;
37     }
38     public String getMsgtype() {
39         return msgtype;
40     }
41     public void setMsgtype(String msgtype) {
42         this.msgtype = msgtype;
43     }
44     public int getAgentid() {
45         return agentid;
46     }
47     public void setAgentid(int agentid) {
48         this.agentid = agentid;
49     }
50 }
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

 1 {
 2    "touser" : "UserID1|UserID2|UserID3",
 3    "toparty" : " PartyID1|PartyID2 ",
 4    "totag" : " TagID1 | TagID2 ",
 5    "msgtype" : "text",
 6    "agentid" : 1,
 7    "text" : {
 8        "content" : "你的快递已到,请携带工卡前往邮件中心领取。\n出发前可查看邮件中心视频实况,聪明避开排队。"
 9    },
10    "safe":0
11 }
View Code

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

 1 /**
 2  * 文本
 3  * @author hh
 4  *
 5  */
 6 public class Text {
 7     //是    消息内容,最长不超过2048个字节
 8     private String content;
 9 
10     public String getContent() {
11         return content;
12     }
13 
14     public void setContent(String content) {
15         this.content = content;
16     }
17 }
View Code

 

TextMessage.java

 1 /**
 2  * 文本消息
 3  * @author hh
 4  *
 5  */
 6 public class TextMessage extends BaseMessage {  
 7     //文本
 8     private Text text;
 9     //否     表示是否是保密消息,0表示否,1表示是,默认0
10     private int safe;
11     
12     public Text getText() {
13         return text;
14     }
15     public void setText(Text text) {
16         this.text = text;
17     }
18     public int getSafe() {
19         return safe;
20     }
21     public void setSafe(int safe) {
22         this.safe = safe;
23     }
24 }
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

 

 1 /**
 2  * 图片、语音、文件
 3  * @author hh
 4  *
 5  */
 6 public class Media {
 7     //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
 8     private String media_id;
 9 
10     public String getMedia_id() {
11         return media_id;
12     }
13 
14     public void setMedia_id(String media_id) {
15         this.media_id = media_id;
16     }    
17 }
View Code

 

1.3.1 图片消息——ImgMessage

 1 /**
 2  * 图片消息
 3  * @author hh
 4  *
 5  */
 6 public class ImgMessage extends BaseMessage {  
 7     //图片
 8     private Media image ;
 9     //否     表示是否是保密消息,0表示否,1表示是,默认0
10     private int safe;
11     
12     public Media getImage() {
13         return image;
14     }
15     public void setImage(Media image) {
16         this.image = image;
17     }
18     public int getSafe() {
19         return safe;
20     }
21     public void setSafe(int safe) {
22         this.safe = safe;
23     }  
24 }

1.3.2 语音消息——VoiceMessage

 1 /**

 3  * @author hh

 6 public class VoiceMessage extends BaseMessage {  
 7     //语音
 8     private Media voice ;
 9     //否     表示是否是保密消息,0表示否,1表示是,默认0
10     private int safe;
11     
12     public Media getVoice() {
13         return voice;
14     }
15     public void setVoice(Media voice) {
16         this.voice = voice;
17     }
18     public int getSafe() {
19         return safe;
20     }

22         this.safe = safe;

1.3.3 文件消息——FileMessage

 1 /**

 6 public class FileMessage extends BaseMessage {  
 7     //文件
 8     private Media file ;
 9     //否     表示是否是保密消息,0表示否,1表示是,默认0
10     private int safe;
11    
12     public Media getFile() {
13         return file;
14     }
15     public void setFile(Media file) {
16         this.file = file;

 7     //是     视频媒体文件id,可以调用上传临时素材接口获取

1.5 文本卡片消息——Textcard、TextcardMessage

Textcard.java

 1 /**
 2  * 文本卡片
 3  * @author hh
 4  *
 5  */
 6 public class Textcard {
 7     //是 标题,不超过128个字节,超过会自动截断
 8     private String title;    
 9     //是    描述,不超过512个字节,超过会自动截断
10     private String description;    
11     //是    点击后跳转的链接。
12     private String url;
13     public String getTitle() {
14         return title;
15     }
16     public void setTitle(String title) {
17         this.title = title;
18     }

22     public void setDescription(String description) {
23         this.description = description;
24     }
25     public String getUrl() {
26         return url;
27     }
28     public void setUrl(String url) {
29         this.url = 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 articles(即Article数组),于是得到以下实体类。

Article.java

 1 /**
 2  * 文章
 3  * @author hh
 4  *
 5  */
 6 public class Article {
 7     //是    标题,不超过128个字节,超过会自动截断
 8     private String title;    
 9     //否    描述,不超过512个字节,超过会自动截断
10     private String description;    
11     //是    点击后跳转的链接。
12     private String url;    
13     //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。
14     private String picurl;
15     public String getTitle() {
16         return title;
17     }
18     public void setTitle(String title) {
19         this.title = title;
20     }
21     public String getDescription() {
22         return description;
23     }
24     public void setDescription(String description) {
25         this.description = description;
26     }
27     public String getUrl() {
28         return url;
29     }
30     public void setUrl(String url) {
31         this.url = url;
32     }
33     public String getPicurl() {
34         return picurl;
35     }
36     public void setPicurl(String picurl) {
37         this.picurl = picurl;
