第三方平台APPID:wx753dec49c48fab55

代码如下

public String msgCallBack(String appId, HttpServletRequest request, String msg_signature, String timestamp, String nonce, String signature) throws Exception {

    System.out.println(appId);
    System.out.println("参数数组" + JsonUtil.obj2String(request.getParameterMap()));
    String postData = HttpUtil.httpRequest2String(request);
    System.out.println("post" + postData);

    WXBizMsgCrypt pc = new WXBizMsgCrypt(token, encodingAesKey, appId);
    // 第三方收到公众号平台发送的消息
    try {
        System.out.println("msg_signture" + msg_signature + "\ntimestamp" + timestamp + "\nnonce" + nonce + "\npostdata" + postData);
        String result2 = pc.decryptMsg(msg_signature, timestamp, nonce, postData);
        System.out.println("解密后明文: " + result2);
    } catch (Exception e) {
        System.out.println(e.toString());
    }

    return "success";
}

参数都已经按照要求进行传参,消息解密就不对
