2. Specific development

2.1 Obtain access_token, and then jsapi_ticket

  * 获取access_token，然后jsapi_ticket
  */

  String access_token = null; // access_token
  String atime = null;// 获取时间
  String a_expires_in = null;// 有效时间(s)
  String ticket = null;// jsapi_ticket
  String ttime = null;// 得到时间
  String t_expires_in = null;// 有效时间(s)
  String access_tokenStr = TUtils.getAccessToken(APPID,
    API_KEY);
  if (access_tokenStr != null
    && access_tokenStr.indexOf("access_token") != -1) {
   try {
    JSONObject jsonObject = new JSONObject(access_tokenStr);
    access_token = jsonObject.getString("access_token");
    a_expires_in = jsonObject.getString("expires_in");
    atime = getCurrentDateStr();
   } catch (JSONException e) {
    // e.printStackTrace();
   }
  }

2.2 Specifically generate signature signature

public String Wx_Signature() {
  String path = ServletActionContext.getServletContext().getRealPath(
    "/wx/");
  // System.out.println(path);
  try {
   String tokenJSON = MyFileUtils.readText(path);
   // String access_token = null; // access_token
   String atime = null;// 获取时间
   String a_expires_in = null;// 有效时间(s)
   String ticket = null;// jsapi_ticket
   // String ttime = null;// 得到时间
   // String t_expires_in = null;// 有效时间(s)
   String result = tokenJSON;
   if (result == null || result.equals("")) {
    tokenJSON = getAccessToken_ticket(path);
   }
   // System.out.println(result);
   if (tokenJSON != null && !tokenJSON.equals("")
     && tokenJSON.indexOf("access_token") != -1) {
    try {
     JSONObject jsonObject = new JSONObject(tokenJSON);
     // access_token = jsonObject.getString("access_token");//
     // access_token
     atime = jsonObject.getString("atime");// 开始时间
     a_expires_in = jsonObject.getString("a_expires_in");// 有效时间
     ticket = jsonObject.getString("ticket");// jsapi_ticket
     // System.out.println(ticket);
     // ttime = jsonObject.getString("ttime");// 开始时间
     // t_expires_in = jsonObject.getString("t_expires_in");//
     // 有效时间
     String t1 = getCurrentDateStr();
     String t2 = atime;
     // System.out.println(atime);
     // System.out.println(a_expires_in);
     // System.out.println(TimeInterval.getInterval(t2, t1));
     long end_time = Long.parseLong(a_expires_in) - 60;
     if (TimeInterval.getInterval(t2, t1) > end_time) {
      ticket = getAccessToken_ticket(path);
     }
    } catch (JSONException e) {
     msg = e.getMessage();
    }
   } else {

   }
   // System.out.println(ticket);
   String url = getParameter("url");
   String noncestr = TUtils.getRandomString(16);
   String timestamp = System.currentTimeMillis() + "";
   timestamp = timestamp.substring(0, 10);
   String data = "jsapi_ticket=" + ticket + "&noncestr=" + noncestr
     + "&timestamp=" + timestamp + "&url=" + url;
   String digest = new SHA1().getDigestOfString(data.getBytes());
   String signature = digest.toLowerCase();// signature
   result = "{\"noncestr\":\"" + noncestr + "\",\"timestamp\":\""
     + timestamp + "\",\"url\":\"" + url + "\",\"signature\":\""
     + signature + "\" ,\"ticket\":\"" + ticket + "\"}";
　　　　　　　　msg = result;
  } catch (IOException e) {
   msg = e.getMessage();
  }
  return msg 
 }

Description: The signature has the number of calls , it needs to be cached in the server's file.
