微信分享朋友圈或好友java代碼

 

1、獲取AccessToken

AccessToken獲取方法

2、獲取 JsApiTicket  

JsApiTicket 獲取方法

3、根據 ticket 和 要分享的頁面url地址去簽名

import cn.hutool.setting.dialect.Props;

import java.io.UnsupportedEncodingException;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
import java.util.Formatter;
import java.util.HashMap;
import java.util.Map;
import java.util.UUID;


public  class WXShareUtil {
	private static Props props = new Props("wei-xin.properties", "utf-8");
	private static String appId = props.getStr("app_id");

	public static Map<String, Object> sign(String jsapi_ticket,String url) {
		Map<String, Object> ret = new HashMap<String, Object>();
		String nonce_str = create_nonce_str();
			String timestamp = create_timestamp();
			String string1;
			String signature = "";
			// 注意這裏參數名必須全部小寫，且必須有序
			string1 = "jsapi_ticket=" + jsapi_ticket + "&noncestr=" + nonce_str
					+ "&timestamp=" + 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);
		ret.put("appid",appId);
		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);
	}
}

4、調用

       // 根據你的實際情況獲取accessToken  和 jsApi_ticket
 
        //獲取accessToken
        String accessToken = WXRedisParam.getAccessToken(app_id,appSecret);
        //獲取jsApi_ticket
        String ticket = WXRedisParam.getJsApiTicket(accessToken,app_id);
        Map<String, Object> sign = WXShareUtil.sign(ticket,url);
        String link = WeChatCode.links_start+userId+","+goodId+ WeChatCode.links_end;
        //link = WXUtils.longToShort(link);//獲取微信短鏈接
        JSONObject object = new JSONObject();
        object.put("sign",sign);
        object.put("url",link);
        object.put("img",good.getPic());
        object.put("title",good.getTitle());
        object.put("desc",good.getAccount());
        return object;
