上一节,我们启用服务器配置的时候,填写了一个服务器地址(url),如下图,这个url就是回调url,是开发者用来接收微信消息和事件的接口URL 。也就是说,用户在微信公众号中发送的消息会被推送到这个回调url,而我们可以接收用户的消息,并进行回复。
官方文档:
我们在上一节中设置的消息加解密方式是安全模式。因此在用户发给公众号的消息(接收消息)以及公众号被动回复用户消息(回复消息)都会加密,
流程:
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。
接收消息:需先从request请求对象的输入流中获取请求参数和已加密的请求消息,再对已加密的请求消息进行解密操作,即可获得明文。
然后就行对明文消息的业务处理了。
回复消息:封装好回复消息后,需先对回复消息进行加密,获得已已加密消息,然后再通过http请求调用被动回复消息的接口,来发送消息。
(1)从请求的输入流中获取加密的请求消息
//1.获取加密的请求消息:使用输入流获得加密请求消息postData ServletInputStream in = request.getInputStream(); BufferedReader reader =new BufferedReader(new InputStreamReader(in)); String tempStr=""; //作为输出字符串的临时串,用于判断是否读取完毕 while(null!=(tempStr=reader.readLine())){ postData+=tempStr; } logger.info("postData:"+postData);
(2)对加密的请求消息进行解密获得明文
WXBizMsgCrypt wxcpt = new WXBizMsgCrypt(Env.TOKEN,Env.ENCODING_AES_KEY,Env.APP_ID); result=wxcpt.DecryptMsg(msgSignature, timeStamp, nonce, postData);
(3)解密算法
直接调用微信官方的 WXBizMsgCrypt 类的 DecryptMsg(String, String, String, String) 方法即可。
直接用官方加解密工具类。
wxcpt = new WXBizMsgCrypt(Env.TOKEN,Env.ENCODING_AES_KEY,Env.APP_ID); replyMsg=wxcpt.EncryptMsg(replyMsg, timeStamp, nonce);
根据官方文档消息的xml传输格式,我们可以将消息封装成对象。请参见后面的代码实现部分
根据官方文档,数据是以XML数据包的形式进行传输的。因此,我们需要
(1)解析微信发来的请求(xmlStr),从xml字符串中获取需要的信息
(2)回复消息时,将消息对象转成xml字符串。
我们是使用dom4j,xstream来进行这个转换的,因此需要导入jar包,maven依赖如下:
<!-- 7.XML解析 --> <dependency> <groupId>dom4j</groupId> <artifactId>dom4j</artifactId> <version>1.6.1</version> </dependency> <dependency> <groupId>com.thoughtworks.xstream</groupId> <artifactId>xstream</artifactId> <version>1.4.10</version> </dependency>
具体请参见代码实现的 MessageUtil 部分。
/** * @desc :1.解析微信发来的请求(XML),获取请求参数 * * @param request * @return * @throws Exception Map<String,String> */ public static Map<String, String> parseXml(HttpServletRequest request) throws Exception { // 将解析结果存储在HashMap中 Map<String, String> map = new HashMap<String, String>(); // 从request中取得输入流 InputStream inputStream = request.getInputStream(); // 读取输入流 SAXReader reader = new SAXReader(); Document document = reader.read(inputStream); // 得到xml根元素 Element root = document.getRootElement(); // 得到根元素的所有子节点 List<Element> elementList = root.elements(); // 遍历所有子节点 for (Element e : elementList) map.put(e.getName(), e.getText()); // 释放资源 inputStream.close(); inputStream = null; return map; }
/** * 2.文本消息对象转换成xml * * @param textMessage 文本消息对象 * @return xml */ public static String textMessageToXml(TextMessage textMessage) { xstream.alias("xml", textMessage.getClass()); return xstream.toXML(textMessage); }
