java获取小程序opneid

java获取小程序opneid的代码

前面准备部分大体和这篇文章一致 https://developers.weixin.qq.com/community/develop/article/doc/000e4c0c26c720fc77f8973d451413

public static String getOpenid(String code) {
    String openid = null;
    Map<String, Object> rtnMap = new HashMap<String, Object>();
    String url = "https://api.weixin.qq.com/sns/jscode2session";
    url += "?appid=" + APPID;//自己的appid
    url += "&secret=" + AppSecret;//密匙
    url += "&js_code=" + code; //你传入的code
    url += "&grant_type=authorization_code";
    byte[] res = null;
    org.apache.http.client.HttpClient httpclient = new DefaultHttpClient();
    HttpGet httpget = new HttpGet(url);
    HttpResponse response = null;
    try {
        response = httpclient.execute(httpget);
        res = IOUtils.toByteArray(response.getEntity().getContent());
    } catch (Exception e) {
 
    } finally {
        if (httpget != null) {
            httpget.abort();
        }
        httpclient.getConnectionManager().shutdown();
    }
    com.alibaba.fastjson.JSONObject jo;
    try {
        jo = JSON.parseObject(new String(res, "utf-8"));
        openid = jo.getString("openid");
    } catch (UnsupportedEncodingException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    return openid;
}

这个代码基本功能可以实现。静态修饰是我为了偷懒而加上的。
