關於微信公眾號呼叫微信分享

自從微信6.0以後,,,WeixinJSBridge.on這個方法不能被輕易使用了,解決的辦法有兩個,
第一個是你們的公眾號去微信申請,申請成功,這個方法依然可以使用,另一個方法就是用JS-SDK,方法如下
備註:在所有操作之前微信公眾號各項功能保證開通:

一,呼叫介面獲取access_token
返回報文為json格式,例如:
第二步:獲取jsapi-ticket
第三步:獲取簽名演算法
簽名演算法程式碼如下:
class Sign {
public static void main(String[] args) {
String jsapi_ticket = "jsapi_ticket";
// 注意
String url = "http://example.com";
Map<String, String> ret = sign(jsapi_ticket, url);
for (Map.Entry
System.out.println(entry.getKey() + ", " + entry.getValue());
}
};
public static Map<String, String> sign(String jsapi_ticket, String url) {
Map<String, String> ret = new HashMap<String, String>();
String nonce_str = create_nonce_str();
String timestamp = create_timestamp();
String string1;
String signature = "";
//注意這裡引數名必須全部小寫,且必須有序
string1 = "jsapi_ticket=" + jsapi_ticket +
"&noncestr=" + nonce_str +
"×tamp=" + timestamp +
"&url=" + url;
System.out.println(string1);
try
{
MessageDigest crypt = MessageDigest.getInstance("SHA-1");
crypt.reset();
crypt.update(string1.getBytes("UTF-8"));
signature = byteToHex(crypt.digest());
}
catch (NoSuchAlgorithmException e)
{
e.printStackTrace();
}
catch (UnsupportedEncodingException e)
{
e.printStackTrace();
}
ret.put("url", url);
ret.put("jsapi_ticket", jsapi_ticket);
ret.put("nonceStr", nonce_str);
ret.put("timestamp", timestamp);
ret.put("signature", signature);
return ret;
}
private static String byteToHex(final byte[] hash) {
Formatter formatter = new Formatter();
for (byte b : hash)
{
formatter.format("%02x", b);
}
String result = formatter.toString();
formatter.close();
return result;
}
private static String create_nonce_str() {
return UUID.randomUUID().toString();
}
private static String create_timestamp() {
return Long.toString(System.currentTimeMillis() / 1000);
}
}
