前期准备：
1.公司域名映射到本机ip
一、配置接收消息API
API配置.jpg
二、URL验证
需结合自身项目情况和官方的回调服务demo完成代码，以下仅供参考（项目未被拆分，只看wx服务器代码即可）
/**
* app服务器
* URL验证转发
* @return
*/
@ResponseBody
@RequestMapping("/message/callback")
public String getUrl(HttpServletRequest request,
@RequestParam("msg_signature")String signature,
@RequestParam("timestamp") String timestamp,
@RequestParam("nonce") String nonce,
@RequestParam("echostr") String echostr) {
String url=Const.getWechatServiceUrl()+"/wx/cp/portal/{agentId}";
System.out.println("pushErrorMessage url:"+url);
Map<String, String> params=new HashMap<String, String>();
params.put("msg_signature", signature);
params.put("timestamp", timestamp);
params.put("nonce", nonce);
params.put("echostr", echostr);
//調用公用微信消息發送接口（app服务器转发到wx服务器）
String result= HttpClientUtil.doGetURL(url, params);
System.out.println(result);
return result;
}
/**
* wx服务器
* Content-Type类型
* text/plain 文本格式
* application/json json数据格式
* application/xml xml数据格式
* */
@GetMapping(produces = "text/plain;charset=utf-8")
public String authGet(@PathVariable Integer agentId,
@RequestParam(name = "msg_signature", required = false) String signature,
@RequestParam(name = "timestamp", required = false) String timestamp,
@RequestParam(name = "nonce", required = false) String nonce,
@RequestParam(name = "echostr", required = false) String echostr) {
this.logger.info("\n接收到来自微信服务器的认证消息：signature = [{}], timestamp = [{}], nonce = [{}], echostr = [{}]",
signature, timestamp, nonce, echostr);
if (StringUtils.isAnyBlank(signature, timestamp, nonce, echostr)) {
throw new IllegalArgumentException("请求参数非法，请核实!");
}
final WxCpService wxCpService = WxCpConfiguration.getCpService(agentId);
if (wxCpService == null) {
throw new IllegalArgumentException(String.format("未找到对应agentId=[%d]的配置，请核实！", agentId));
}
if (wxCpService.checkSignature(signature, timestamp, nonce, echostr)) {
String sEchoStr = new WxCpCryptUtil(wxCpService.getWxCpConfigStorage()).decrypt(echostr);
this.logger.debug("\n返回的明文：{}",sEchoStr);
return sEchoStr;
}
return "非法请求";
}
利用官方调试工具验证URL是否配置成功

三、被动回复
需结合自身项目情况和官方的回调服务demo完成代码，以下仅供参考（项目未被拆分，只看wx服务器代码即可）
/**
* app服务器
* 转发用户回复的信息
* @return
*/
@ResponseBody
@PostMapping("/message/callback")
public String postMessage(@RequestBody String requestBody,
@RequestParam("msg_signature") String signature,
@RequestParam("timestamp") String timestamp,
@RequestParam("nonce") String nonce) {
String url=Const.getWechatServiceUrl()+"/wx/cp/portal/{agentId}";
//System.out.println("postMessage url:"+url);
Map<String, String> params=new HashMap<String, String>();
params.put("msg_signature", signature);
params.put("timestamp", timestamp);
params.put("nonce", nonce);
params.put("body", requestBody);
//調用公用微信消息發送接口
String result= HttpClientUtil.doPostMessage(url, params);
JSONObject object= JSONObject.parseObject(result);
//返回xml格式数据到企业微信
String xml = object.get("out").toString();
System.out.println(xml);
return xml;
}
/**
* wx服务器
* Content-Type类型
* text/plain 文本格式
* application/json json数据格式
* application/xml xml数据格式
* */
@PostMapping(produces = "application/json; charset=UTF-8")
public R post(@PathVariable Integer agentId,
@RequestParam("msg_signature") String signature,
@RequestParam("timestamp") String timestamp,
@RequestParam("nonce") String nonce,
@RequestParam("body") String requestBody) {
this.logger.info("\n接收微信请求：\n[signature=[{}],\n timestamp=[{}],\n nonce=[{}],\n requestBody=[\n{}\n] ",signature, timestamp, nonce, requestBody);
R r;
final WxCpService wxCpService = WxCpConfiguration.getCpService(agentId);
WxCpXmlMessage inMessage = WxCpXmlMessage.fromEncryptedXml(requestBody, wxCpService.getWxCpConfigStorage(),timestamp, nonce, signature);
this.logger.debug("\n消息解密后内容为：\n{} ", JsonUtils.toJson(inMessage));
//根据不同类型做出不同被动响应
if(inMessage.getMsgType().equals("text")){
WxCpXmlOutMessage text = WxCpXmlOutMessage
.TEXT()
.toUser(inMessage.getToUserName())
.fromUser(inMessage.getFromUserName())
.content("文本消息")
.build();
String out = text.toEncryptedXml(wxCpService.getWxCpConfigStorage());
r=R.ok("回复成功。");
r.put("out", out);
r.put("message", inMessage);
return r;
}
}
