微信AirKiss 配网界面调起Demo
最近硬件大哥又提出新需求，想要在我们的硬件上加上微信的AirKiss，用这个来实现wifi设备配网，之前的我们的硬件都是采取的蓝牙配网，不过配网好像没有那么方便，使用了微信这种配网方式，发现挺方便，且可行性比较高，所以呢，楼主又得开始进行这方面开发了，楼主看着微信网页的开发文档还是撸出来了，下面具体讲一下
第一步：
先用微信公众号的appid和秘钥去获取微信的acctoken
"https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=" + appid + "&secret=" + appsecret;
第二步：
用拿到的acctoken去获取ticket
"https://api.weixin.qq.com/cgi-bin/ticket/getticket?&type=jsapi&access_token=" + acctoken;
第三步：
用当前网址、获取到的ticket、随机生成字符串、当前时间戳去按照字母排序组合成字符串，这种格式的
String key = "jsapi_ticket=" + ticket + "&noncestr=" + noncestr + "×tamp=" + timeStamp + "&url=" + localurl;
第四步：
对生成的字符串用sha1加密算法，拿到sign签名
Sign = hash(key, "SHA1");
第五步：
看全部代码

String appid = "您的APPID";
String appsecret = "您的APPSECRECT";
String acctokenurl = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=" + appid
+ "&secret=" + appsecret;
String ticketurl = "https://api.weixin.qq.com/cgi-bin/ticket/getticket?&type=jsapi&access_token=";
String localurl = "当前文件的访问地址";
String timeStamp = System.currentTimeMillis() / 1000 + "";
String noncestr = "";
String ticket = "";
String Sign = "";
/**

public String hash(String string, String algorithm) {
if (string.isEmpty()) {
return "";
}
MessageDigest hash = null;
try {
hash = MessageDigest.getInstance(algorithm);
byte[] bytes = hash.digest(string.getBytes("UTF-8"));
String result = "";
for (byte b : bytes) {
String temp = Integer.toHexString(b & 0xff);
if (temp.length() == 1) {
temp = "0" + temp;
}
result += temp;
}
return result;
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
return "";
}
public void getmethof() {
JSONObject acctokenJson = HttpsUtils.httpsRequest(acctokenurl, "GET", null);
if (!acctokenJson.containsKey("access_token")) {
return;
}
String acctoken = acctokenJson.getString("access_token");
JSONObject ticketjson = HttpsUtils.httpsRequest(ticketurl + acctoken, "GET", null);
if (!ticketjson.containsKey("ticket")) {
return;
}
ticket = ticketjson.getString("ticket");
noncestr = RandCharsUtils.getRandomString(16);
String key = "jsapi_ticket=" + ticket
+ "&noncestr=" + noncestr
+ "×tamp=" + timeStamp
+ "&url=" + localurl;
System.out.println(key);
Sign = hash(key, "SHA1");
System.out.println(Sign);
