这篇文章主要为大家详细介绍了微信jsapi ticket接口签名，具有一定的参考价值，感兴趣的小伙伴们可以参考一下
本文实例为大家分享了微信js接口签名的具体代码，供大家参考，具体内容如下
1、微信 js 接口签名校验工具
2、具体开发
2.1 获取access_token，然后jsapi_ticket
/**
* 获取access_token，然后jsapi_ticket
*/
private string getaccesstoken_ticket(string 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 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();
}
}
if (access_token != null && !access_token.equals("")) {
string ticketstr = ticketutils.getjsapiticket(access_token);
// system.out.println("ticketstr:" + ticketstr);
if (ticketstr != null && ticketstr.indexof("ticket") != -1) {
try {
jsonobject jsonobject = new jsonobject(ticketstr);
ticket = jsonobject.getstring("ticket");
t_expires_in = jsonobject.getstring("expires_in");
ttime = getcurrentdatestr();
} catch (jsonexception e) {
// e.printstacktrace();
}
}
}
string result = null;
if (ticket != null && !ticket.equals("")) {
result = "{\"access_token\":\"" + access_token
+ "\",\"a_expires_in\":\"" + a_expires_in
+ "\",\"atime\":\"" + atime + "\",\"ticket\":\"" + ticket
+ "\",\"t_expires_in\":\"" + t_expires_in
+ "\",\"ttime\":\"" + ttime + "\"}";
if (myfileutils.writeintotext(path, result)) {
// system.out.println("写入文件成功");
// system.out.println(result);
} else {
system.out.println("写入微信签名文件失败");
}
}
return result;
}
public static string getaccesstoken(string appid, string appsecret) {
string url = "https://api.weixin.qq.com/cgi-bin/token";
string params = "grant_type=client_credential&appid=" + appid
+ "&secret=" + appsecret;
string resultstr = httprequest.sendget(url, params);
// sendget：用get方法获取数据 ,具体请参考之间的关于微信的文章 http://www.cnblogs.com/jiduoduo/p/5749363.html
return resultstr;
}
/**
* 根据access_token获取ticket { "errcode":0, "errmsg":"ok", "ticket":
* "bxldikrxvbtpdhsm05e5u5suoxnkd8-41zo3mhkoyn5ofkwitdggnr2fwj0m9e8nyzwkvzvdvtaugwvsdshfka"
* , "expires_in":7200 }
*
* @param access_token
* @return
*/
public static string getjsapiticket(string access_token) {
string url = "https://api.weixin.qq.com/cgi-bin/ticket/getticket";
string params = "type=jsapi&access_token=" + access_token;
string resultstr = httprequest.sendget(url, params);
return resultstr;
}
2.2具体生成签名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
+ "×tamp=" + 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
}
说明：签名是有调用次数，需要将其cache到服务器的文件中。
