快速搭建微信公众平台服务器

简单封装了所有与微信服务器交互的消息:文本消息、图片消息、图文消息等等
提供MenuAPI、UserApi、UserTagAPI、MediaAPI、OauthAPI。。。。等等等等用于实现所有高级接口功能，使用极其简单

Demo---传送门：(https://github.com/adminzhou/EasyWeChatDemo)

API列表

关于函数名

我喜欢get_xxx_xxx的方式命名。虽然 ！！不规范， 那你来打我啊

使用步骤

1.下载EasyWeChat

2.将EasyWechat引入项目

3.新建weixin.properties

3.1配置weixin.properties文件

开发者模式
devMode = true
微信接入token
token = easywechat
第三方用户凭证
appid = wx0f687dead13778fb
第三方用户密钥
appsecret = fa593b36a401c7c59d8ea978018f9a5b
oauthUrl 网页授权链接
url = http://1467a8b6.ngrok.io/oauth
消息处理器
handler = cn.spring4.weixin.WeixinHandler

3.2更换配置信息

==================================================

基于springmvc项目的集成方法

@Controller
public class HelloWorld {
	@RequestMapping("/")
	public String index() {
		return "index";
	}

	/**
	 * 接入微信，并且向微信返回信息</br>
	 * 接入流程请看 拦截器
	 * @param request
	 * @param response
	 * @return
	 * @throws IOException
	 */
	@RequestMapping(value = "/weixin", produces = "text/html;charset=UTF-8")
	@ResponseBody
	public String weixin(HttpServletRequest request) throws IOException {
		ServletInputStream inputStream = request.getInputStream();
		String outMsg = Weixin.getOutMsg(inputStream);
		return outMsg;
	}

	/**
	 * 获取用户授权，并且获取用户资料
	 * 
	 * @param code
	 * @param resp
	 * @throws IOException
	 * @throws NoSuchAlgorithmException
	 */
	@RequestMapping("/oauth")
	public void oauth(String code, HttpServletResponse resp) throws IOException, NoSuchAlgorithmException {
		Oauth2 o2 = new Oauth2();
		if (StrKit.isBlank(code)) {
			resp.sendRedirect(o2.getSnsapi_userinfoUrl());
			return;
		}
		Oauth2Token token = o2.login(code);
		UserInfo info = o2.getUserInfo(token.getAccess_token(), token.getOpenid());
		System.out.println("info==" + info.toString());
		return;
	}
}

拦截器

public class WeixinInterceptor implements HandlerInterceptor {
	/**
	 * 如果请求为get，则为微信认证接入
	 */
	public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)
			throws Exception {
		String method = request.getMethod();
		if (method.equalsIgnoreCase("post")) {
			return true;
		}
		String signature = request.getParameter("signature");
		String timestamp = request.getParameter("timestamp");
		String nonce = request.getParameter("nonce");
		String echostr = request.getParameter("echostr");
		boolean checkSignature = WeiXinAccess.checkSignature(PropertiesUtil.getToken(), signature, timestamp, nonce);
		if (!checkSignature) {
			System.out.println("请确认请求是否来自微信");
			return false;
		}
		response.getOutputStream().write(echostr.getBytes("utf-8"));
		return false;
	}

	public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler,
			ModelAndView modelAndView) throws Exception {
		// TODO Auto-generated method stub

	}

	public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex)
			throws Exception {
		// TODO Auto-generated method stub

	}

}
