5. 微信服务端繁忙自动重试的功能
|
||||
6. 提供微信错误信息的异常处理机制
|
||||
|
||||
## 微信消息路由器
|
||||
# Quickstart
|
||||
|
||||
你可以使用``WxMessageRouter``来对微信推送过来的消息、事件进行路由，交给的``WxMessageHandler``处理。
|
||||
## 打包
|
||||
|
||||
使用方法：
|
||||
|
||||
```java
|
||||
WxMessageRouter router = new WxMessageRouter();
|
||||
router
|
||||
.rule()
|
||||
.msgType("MSG_TYPE")
|
||||
.event("EVENT")
|
||||
.eventKey("EVENT_KEY")
|
||||
.content("CONTENT")
|
||||
.interceptor(interceptor).handler(handler)
|
||||
.end()
|
||||
.rule()
|
||||
.msgType("MSG_TYPE")
|
||||
.handler(handler)
|
||||
.end()
|
||||
;
|
||||
|
||||
// 将WxXmlMessage交给消息路由器
|
||||
WxXmlMessage message = WxXmlMessage.fromXml(xml);
|
||||
router.route(message);
|
||||
如果你可以跳过单元测试直接打包：
|
||||
```bash
|
||||
mvn clean install -Dmaven.test.skip=true
|
||||
```
|
||||
|
||||
1. 开发人员需实现自己的``WxMessageHandler``和``WxMessageInterceptor``
|
||||
1. 配置路由规则时要按照从细到粗的原则，否则可能消息可能会被提前处理
|
||||
2. 默认情况下消息只会被处理一次，除非使用 ``Rule.next()``
|
||||
3. 规则的结束必须用``Rule.end()``或者``Rule.next()``，否则不会生效
|
||||
4. 具体使用可以看源代码中的``WxMessageRouterTest``单元测试，或者查看Javadoc
|
||||
|
||||
### 同步回复
|
||||
|
||||
``WxMessageRouter``默认使用异步的方式处理消息，如果要使用同步的方式处理消息，那么可以这样：
|
||||
|
||||
```java
|
||||
router
|
||||
.rule()
|
||||
.async(false)
|
||||
.handler(handler)
|
||||
.end()
|
||||
;
|
||||
|
||||
WxXmlMessage message = WxXmlMessage.fromXml(xml);
|
||||
// 获得同步的返回结果
|
||||
WxXmlMessage res = router.route(message);
|
||||
String xml = res.toXml();
|
||||
// ... 将xml写入HttpServletResponse
|
||||
```
|
||||
|
||||
|
||||
## 微信Java API
|
||||
|
||||
使用``WxService``可以调用微信API。目前已实现除“微信小店”以外的所有功能。
|
||||
|
||||
### 构造WxService
|
||||
|
||||
``WxService``依赖于``WxConfigStorage``，``WxConfigStorage``是微信客户端配置所存储的地方，本工具提供了默认基于内存的实现：``WxInMemoryConfigStorage``。您可能在实际使用时需要提供自己的实现，比如在集群环境下存储到数据库中。
|
||||
|
||||
|
||||
```java
|
||||
WxConfigStorage config = new WxInMemoryConfigStorage();
|
||||
config.setAppId(...);
|
||||
config.setSecret(...);
|
||||
config.setToken(...);
|
||||
WxServiceImpl wxService = new WxServiceImpl();
|
||||
wxService.setWxConfigStorage(config);
|
||||
```
|
||||
|
||||
### 验证消息
|
||||
|
||||
```java
|
||||
if(!wxService.checkSignature(timestamp, nonce, signature)) {
|
||||
// 验证失败
|
||||
}
|
||||
```
|
||||
|
||||
### 刷新access_token
|
||||
|
||||
```java
|
||||
wxService.accessTokenRefresh();
|
||||
```
|
||||
|
||||
刷新后的accessToken存在WxConfigStorage中。
|
||||
|
||||
### 多媒体文件
|
||||
|
||||
#### 上传多媒体文件
|
||||
```java
|
||||
InputStream inputStream = ...;
|
||||
File file = ...;
|
||||
WxMediaUploadResult res = wxService.mediaUpload(mediaType, fileType, inputStream);
|
||||
// 或者
|
||||
res = wxService.mediaUpload(mediaType, file);
|
||||
res.getType();
|
||||
res.getCreated_at();
|
||||
res.getMedia_id();
|
||||
res.getThumb_media_id();
|
||||
```
|
||||
|
||||
#### 下载多媒体文件
|
||||
```java
|
||||
// 获得一个在系统临时目录的文件
|
||||
File file = wxService.mediaDownload(media_id);
|
||||
```
|
||||
|
||||
### 分组管理
|
||||
|
||||
#### 创建分组
|
||||
```java
|
||||
WxGroup res = wxService.groupCreate("测试分组1");
|
||||
```
|
||||
|
||||
#### 获得分组列表
|
||||
```java
|
||||
List<WxGroup> groupList = wxService.groupGet();
|
||||
```
|
||||
|
||||
#### 更新分组名
|
||||
```java
|
||||
WxGroup g = new WxGroup();
|
||||
g.setId(...);
|
||||
g.setName(...);
|
||||
wxService.groupUpdate(group);
|
||||
```
|
||||
|
||||
### 用户管理
|
||||
|
||||
#### 更新用户备注名
|
||||
```java
|
||||
wxService.userUpdateRemark(openid, "测试备注名");
|
||||
```
|
||||
|
||||
#### 获得用户信息
|
||||
```java
|
||||
String lang = "zh_CN"; //语言
|
||||
WxUser user = wxService.userInfo(openid, lang);
|
||||
```
|
||||
|
||||
#### 获得用户列表
|
||||
```java
|
||||
WxUserList wxUserList = wxService.userList(next_openid);
|
||||
```
|
||||
|
||||
#### 查询用户所在分组
|
||||
```java
|
||||
long groupid = wxService.userGetGroup(openid);
|
||||
```
|
||||
|
||||
#### 将用户移到分组
|
||||
```java
|
||||
wxService.userUpdateGroup(openid, to_groupid);
|
||||
```
|
||||
|
||||
### 发送客服消息
|
||||
|
||||
```java
|
||||
WxCustomMessage message = new WxCustomMessage();
|
||||
// 设置消息的内容等信息
|
||||
wxService.customMessageSend(message);
|
||||
```
|
||||
|
||||
### 群发消息
|
||||
|
||||
下面用用户列表群发（``WxMassOpenIdsMessage``）做例子，如果要使用分组群发，则使用``WxMassGroupMessage``即可。
|
||||
|
||||
#### 文本消息
|
||||
```java
|
||||
WxMassOpenIdsMessage massMessage = new WxMassOpenIdsMessage();
|
||||
massMessage.setMsgtype(WxConsts.MASS_MSG_TEXT);
|
||||
massMessage.setContent("消息内容");
|
||||
massMessage.getTouser().add(openid);
|
||||
|
||||
WxMassSendResult massResult = wxService.massOpenIdsMessageSend(massMessage);
|
||||
```
|
||||
|
||||
#### 视频消息
|
||||
```java
|
||||
WxMediaUploadResult uploadMediaRes = wxService.mediaUpload(WxConsts.MEDIA_VIDEO, WxConsts.FILE_MP4, inputStream);
|
||||
|
||||
// 把视频变成可被群发的媒体
|
||||
WxMassVideo video = new WxMassVideo();
|
||||
video.setTitle("测试标题");
|
||||
video.setDescription("测试描述");
|
||||
video.setMedia_id(uploadMediaRes.getMedia_id());
|
||||
WxMassUploadResult uploadResult = wxService.massVideoUpload(video);
|
||||
|
||||
WxMassOpenIdsMessage massMessage = new WxMassOpenIdsMessage();
|
||||
massMessage.setMsgtype(WxConsts.MASS_MSG_VIDEO);
|
||||
massMessage.setMedia_id(uploadResult.getMedia_id());
|
||||
massMessage.getTouser().add(openid);
|
||||
|
||||
WxMassSendResult massResult = wxService.massOpenIdsMessageSend(massMessage);
|
||||
```
|
||||
|
||||
#### 图片消息
|
||||
```java
|
||||
WxMediaUploadResult uploadMediaRes = wxService.mediaUpload(WxConsts.MEDIA_IMAGE, WxConsts.FILE_JPG, inputStream);
|
||||
|
||||
WxMassOpenIdsMessage massMessage = new WxMassOpenIdsMessage();
|
||||
massMessage.setMsgtype(WxConsts.MASS_MSG_IMAGE);
|
||||
massMessage.setMedia_id(uploadMediaRes.getMedia_id());
|
||||
massMessage.getTouser().add(openid);
|
||||
|
||||
WxMassSendResult massResult = wxService.massOpenIdsMessageSend(massMessage);
|
||||
```
|
||||
|
||||
#### 语音消息
|
||||
```java
|
||||
WxMediaUploadResult uploadMediaRes = wxService.mediaUpload(WxConsts.MEDIA_VOICE, WxConsts.FILE_MP3, inputStream);
|
||||
|
||||
WxMassOpenIdsMessage massMessage = new WxMassOpenIdsMessage();
|
||||
massMessage.setMsgtype(WxConsts.MASS_MSG_VOICE);
|
||||
massMessage.setMedia_id(uploadMediaRes.getMedia_id());
|
||||
massMessage.getTouser().add(openid);
|
||||
|
||||
WxMassSendResult massResult = wxService.massOpenIdsMessageSend(massMessage);
|
||||
```
|
||||
|
||||
#### 图文消息
|
||||
```java
|
||||
// 先上传图文消息里需要的图片
|
||||
WxMediaUploadResult uploadMediaRes = wxService.mediaUpload(WxConsts.MEDIA_IMAGE, WxConsts.FILE_JPG, inputStream);
|
||||
|
||||
WxMassNews news = new WxMassNews();
|
||||
WxMassNewsArticle article1 = new WxMassNewsArticle();
|
||||
article1.setTitle("标题1");
|
||||
article1.setContent("内容1");
|
||||
article1.setThumb_media_id(uploadMediaRes.getMedia_id());
|
||||
news.addArticle(article1);
|
||||
|
||||
WxMassNewsArticle article2 = new WxMassNewsArticle();
|
||||
article2.setTitle("标题2");
|
||||
article2.setContent("内容2");
|
||||
article2.setThumb_media_id(uploadMediaRes.getMedia_id());
|
||||
article2.setShow_cover_pic(true);
|
||||
article2.setAuthor("作者2");
|
||||
article2.setContent_source_url("www.baidu.com");
|
||||
article2.setDigest("摘要2");
|
||||
news.addArticle(article2);
|
||||
|
||||
WxMassUploadResult massUploadResult = wxService.massNewsUpload(news);
|
||||
|
||||
WxMassOpenIdsMessage massMessage = new WxMassOpenIdsMessage();
|
||||
massMessage.setMsgtype(WxConsts.MASS_MSG_NEWS);
|
||||
massMessage.setMedia_id(uploadResult.getMedia_id());
|
||||
massMessage.getTouser().add(openid);
|
||||
|
||||
WxMassSendResult massResult = wxService.massOpenIdsMessageSend(massMessage);
|
||||
```
|
||||
|
||||
### 自定义菜单

## 如何执行单元测试
|
||||
将 ``src/test/resources/test-config.sample.xml`` 改成 ``test-config.xml`` 设置appId, secret, accessToken(可选), openId
|
||||
如果你需要执行本项目的单元测试代码，那么你需要将 ``src/test/resources/test-config.sample.xml`` 改成 ``test-config.xml`` ，并设置appId, secret, accessToken(可选), openId，然后执行：
|
||||
|
||||
```bash
|
||||
mvn clean test
|
||||
mvn clean install
|
||||
```
|
||||
|
||||
在你的maven项目中添加：
|
||||
```xml
|
||||
<dependency>
|
||||
<groupId>chanjarster.weixin</groupId>
|
||||
<artifactId>weixin-java-tools</artifactId>
|
||||
<version>1.0.0-SNAPSHOT</version>
|
||||
</dependency>
|
||||
```
|
||||
|
||||
## Hello World
|
||||
```java
|
||||
WxConfigStorage config = new WxInMemoryConfigStorage();
|
||||
config.setAppId(...); // 设置微信公众号的appid
|
||||
config.setSecret(...); // 设置微信公众号的app secret
|
||||
config.setToken(...); // 设置微信公众号的token
|
||||
|
||||
WxServiceImpl wxService = new WxServiceImpl();
|
||||
wxService.setWxConfigStorage(config);
|
||||
|
||||
// 用户的openid在下面地址获得
|
||||
// https://mp.weixin.qq.com/debug/cgi-bin/apiinfo?t=index&type=用户管理&form=获取关注者列表接口%20/user/get
|
||||
String openid = ...;
|
||||
WxCustomMessage message = WxCustomMessage.TEXT().toUser(openid).content("Hello World").build();
|
||||
wxService.customMessageSend(message);
|
||||
```
|
||||
