今天完成的事情

申请了一个微信测试公众号，用servlet接入

需要绑定域名，直接用了模拟域名工具生成的域名

public void doGet(HttpServletRequest request, HttpServletResponse response)throws IOException{
    String signature = request.getParameter("signature");
    String timestamp = request.getParameter("timestamp");
    String nonce = request.getParameter("nonce");
    String echostr = request.getParameter("echostr");
   PrintWriter out = response.getWriter();
    if (CheckUtil.checkSignature(signature,timestamp,nonce)){
        out.print(echostr);
    }
    PrintWriter out = response.getWriter();
    out.print(echostr);
}

参数含义：

在服务器上验证之后，就可以返回echostr给微信服务器，就绑定成功了

通过get请求access_token:

public static JsonObject doGetStr(String url)throws IOException{
    DefaultHttpClient client = new DefaultHttpClient();
    HttpGet httpGet = new HttpGet(url);

    JsonObject jsonObject=null;
    HttpResponse httpResponse = client.execute(httpGet);
    HttpEntity entity = httpResponse.getEntity();
    if (entity != null){
        String result = EntityUtils.toString(entity,"UTF-8");
        jsonObject = new JsonParser().parse(result).getAsJsonObject();

    }
    return jsonObject;
}

access_token有效期为两小时，需要定时刷新

明天的计划
