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;
} }
