第一步：获取微信推送component_verify_ticket
try {WXBizMsgCrypt wxBizMsgCrypt = new WXBizMsgCrypt(MyApp.token,MyApp.encodingAesKey, MyApp.OpenAppId);String postData = GetPostData(request);String msgSignature = request.getParameter("msg_signature");String timeStamp = request.getParameter("timestamp");String nonce = request.getParameter("nonce");String ret = wxBizMsgCrypt.decryptMsg(msgSignature, timeStamp,nonce, postData);// 得到component_verify_ticketDocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();DocumentBuilder db = dbf.newDocumentBuilder();StringReader sr = new StringReader(ret);InputSource is = new InputSource(sr);Document document = db.parse(is);Element root = document.getDocumentElement();NodeList nodelist1 = root.getElementsByTagName("ComponentVerifyTicket");if (nodelist1.item(0) != null) { // 因为全网发布的时候，传过来的xml不含有ComponentVerifyTicket字段，直接使用会造成空指针MyApp.component_verify_ticket = nodelist1.item(0).getTextContent(); // 有效时间10分钟}setPreState("component_verify_ticket",MyApp.component_verify_ticket); // 保存到文件中} catch (Exception e) {e.printStackTrace();}response.setContentType("text/plain; charset=utf-8");response.setHeader("Pragma", "no-cache");response.addHeader("Cache-Control", "must-revalidate");response.addHeader("Cache-Control", "no-cache");response.addHeader("Cache-Control", "no-store");response.setDateHeader("Expires", 0);response.setCharacterEncoding("utf-8");PrintWriter out = response.getWriter();out.print("success");out.flush();out.close();第二步：获取第三方平台component_access_token
String component_aceess_token_url = getComponentAccessTokenUrl;JSONObject jsonObject = new JSONObject();jsonObject.put("component_appid", MyApp.OpenAppId);jsonObject.put("component_appsecret", MyApp.OpenAppSecret);jsonObject.put("component_verify_ticket", MyApp.component_verify_ticket);String jsonStr = jsonObject.toString();System.out.println("提交给微信获取component_access_token的JSON:" + jsonStr);MyResponse myResponse = HttpUtil.request(component_aceess_token_url, false, jsonStr.getBytes("UTF-8"), true);第三步：获取预授权码pre_auth_codeString pre_auth_code_url = getpreauthcodeUrl;pre_auth_code_url = pre_auth_code_url.replace("ACCESSTOKEN",componentAccessToken);JSONObject jsonObject = new JSONObject();jsonObject.put("component_appid", MyApp.OpenAppId);String jsonStr = jsonObject.toString();MyResponse myResponse = HttpUtil.request(pre_auth_code_url, false,jsonStr.getBytes("UTF-8"), true);String PreAuthCodeStr = myResponse.getString();JSONObject PreAuthCodeJson = JSONObject.fromObject(PreAuthCodeStr);value = PreAuthCodeJson.getString("pre_auth_code");System.out.println("预授权码：:" + value);第四步：使用授权码换取公众号的接口调用凭据和授权信息 和
获取授权方的公众号帐号基本信息
//授权后回调URI，得到授权码（authorization_code）和过期时间 //获取（刷新）授权公众号的接口调用凭据（令牌） String schoolId = request.getParameter("schoolId");String auth_code = request.getParameter("auth_code"); //授权码 有效期10分钟String authorization_info_url = getauthorization_info;authorization_info_url = authorization_info_url.replace("ACCESSTOKEN", GetPreAuthCode.getComponentAccessToken());JSONObject jsonObject = new JSONObject();jsonObject.put("component_appid", OpenAppId);jsonObject.put("authorization_code",auth_code);String jsonStr = jsonObject.toString();MyResponse myResponse = HttpUtil.request(authorization_info_url, false , jsonStr.getBytes("UTF-8"), true);String authorization_info = myResponse.getString();JSONObject object = JSONObject.parseObject(authorization_info);System.out.println("授权信息："+object);object = object.getJSONObject("authorization_info");String authorizer_appid = object.getString("authorizer_appid");//授权方appidString authorizer_refresh_token = object.getString("authorizer_refresh_token");//接口调用凭据刷新令牌//获取授权方的公众号帐号基本信息System.out.println("获取公众号基本信息。。。。。。");String getauthorization_info_url = get_authorizer_info;authorization_info_url = getauthorization_info_url.replace("ACCESSTOKEN", GetPreAuthCode.getComponentAccessToken());JSONObject jsonObject2 = new JSONObject();jsonObject2.put("component_appid", OpenAppId);jsonObject2.put("authorizer_appid",authorizer_appid);String jsonStr2 = jsonObject2.toString();MyResponse myResponse2 = HttpUtil.request(authorization_info_url, false , jsonStr2.getBytes("UTF-8"), true);String authorizer_info = myResponse2.getString();JSONObject object2 = JSONObject.parseObject(authorizer_info);System.out.println("公众号基本信息："+object2)其让接口尚未使用，所以这里不作说明。全网发布：if (("gh_3c884a361561").equals(toUserName)) { if(nodelist6.item(0)!= null){ content = nodelist6.item(0).getTextContent(); } if(("event").equals(msgType)){ //事件消息 System.out.println("进去了吗。。。。。。。。"); textMessage.setContent("LOCATION" + "from_callback"); String respMessage = MessageUtil .textMessageToXml(textMessage); String result = wxBizMsgCrypt.encryptMsg(respMessage, timeStamp, nonce); respXml = result; }else if(("text").equals(msgType)){ //普通文本消息 if (content.contains("TESTCOMPONENT_MSG_TYPE_TEXT")) { content = "TESTCOMPONENT_MSG_TYPE_TEXT_callback"; textMessage.setContent(content); String respMessage = MessageUtil .textMessageToXml(textMessage); String result = wxBizMsgCrypt.encryptMsg(respMessage, timeStamp, nonce); respXml = result; }else if(content.contains("QUERY_AUTH_CODE")){ //返回api文本消息 response.getWriter().print(""); content = content.substring(content.indexOf(":") + 1); System.out.println(content); String authorization_info_url = "https://api.weixin.qq.com/cgi-bin/component/api_query_auth?component_access_token=ACCESSTOKEN"; authorization_info_url = authorization_info_url .replace("ACCESSTOKEN", GetPreAuthCode .getComponentAccessToken()); JSONObject jsonObject = new JSONObject(); jsonObject.put("component_appid", MyApp.OpenAppId); jsonObject.put("authorization_code", content); String jsonStr = jsonObject.toString(); MyResponse myResponse = HttpUtil.request( authorization_info_url, false, jsonStr .getBytes("UTF-8"), true); String authorization_info = myResponse.getString(); JSONObject object = JSONObject .parseObject(authorization_info); System.out.println("授权信息：" + object); object = object.getJSONObject("authorization_info"); String accssToken = object .getString("authorizer_access_token"); System.out.println("accsstoken:" + accssToken); String url22 = "https://api.weixin.qq.com/cgi-bin/message/custom/send?access_token=ACCESS_TOKEN"; String dataMessage = ""; dataMessage += "{"; dataMessage += "\"touser\":\"" + fromUserName + "\","; dataMessage += "\"msgtype\":\"text\","; dataMessage += "\"text\":"; dataMessage += "{"; dataMessage += "\"content\":\"" + content + "_from_api" + "\""; dataMessage += "}"; dataMessage += "}"; url22 = url22.replace("ACCESS_TOKEN", accssToken); MyResponse mString = HttpUtil.request(url22, false, dataMessage.getBytes("UTF-8"), true); } } } 就个人经历，总结易导致不通过点：1.处理返回普通文本和事件消息记得加密；2.处理返回api文本注意回复一个空字符串以及注意调用客服接口时的数据格式，曾经吃过亏，报过 invalid openid.3.可能是我太过不幸运，测试了上百次都是没有得到过事件消息的推送，测试各种方法，最后没办法，怀疑权限集那里，勾上了一些就好了。最后吐槽一些，微信文档写的真的不咋的，坑太多。 0 0
