微信官方验证主要参数

        String signature = request.getParameter("signature");

        String echostr = request.getParameter("echostr");

        String timestamp = request.getParameter("timestamp");

        String nonce = request.getParameter("nonce");

echostr，如果此参数为空：正常处理微信消息即可，反之为验证。

下面来看一下主要代码：

// 微信消息处理流程		if (null == echostr || echostr.isEmpty()) {			request.setCharacterEncoding("UTF-8");			response.setCharacterEncoding("UTF-8");			xml = WeChatUtils.readStreamParameter(request.getInputStream());			if (null != xml && !xml.isEmpty()) {				if (null != db) {					result = WeChatUtils.processWechatMag(xml, db.getAttention_reply());					response.getWriter().print(result);					response.getWriter().flush();					response.getWriter().close();				} else {					result = WeChatUtils.processWechatMag(xml, attention_reply);					response.getWriter().print(result);					response.getWriter().flush();					response.getWriter().close();				}			} else {				response.getWriter().print("error");				response.getWriter().flush();				response.getWriter().close();			}		}		// 微信验证处理流程		else {			if (null != db) {				if (WeChatUtils.checkSignature(signature, timestamp, nonce, db.getWeixin_token())) {					response.getWriter().print(echostr);					response.getWriter().flush();					response.getWriter().close();				} else {					response.getWriter().print("error");					response.getWriter().flush();					response.getWriter().close();				}			} else {				response.getWriter().print("error");				response.getWriter().flush();				response.getWriter().close();			}		}
