基于微信，写一个方法实现长链接转换成短链接

[c1140707812]

实现一个公共API，提供一个URL转换接口，如：
class UrlUtil {
......
public static String ltos(String lurl) {
.........
}
......

微信已经有这个接口了，还重复造炉子？

                log.info("生成短链接成功 shortURL:{}", shortURL);

                log.error("创建永久带参二维码失败 errcode:{} errmsg:{}", errorCode, errorMsg);
            }
        }

        return shortURL;
    }

这个才是对的

/**
     * 长链接转成短链接 提高扫码速度和成功率
     *
     * @param accessToken
     * @param URL
     * @return
     */
    public static String shortURL(String accessToken, String URL) {
        String shortURL = null;
        String requestUrl = "https://api.weixin.qq.com/cgi-bin/shorturl?access_token=ACCESS_TOKEN";
        requestUrl = requestUrl.replace("ACCESS_TOKEN", accessToken);
        String jsonMsg = "{\"action\":\"long2short\",\"long_url\":\"%s\"}";
        JSONObject jsonObject = CommonUtil.httpsRequest(requestUrl, "POST", String.format(jsonMsg, URL));
        if (null != jsonObject) {
            try {
                shortURL = jsonObject.getString("short_url");
                log.info("生成短链接成功 shortURL:{}", shortURL);
            } catch (Exception e) {
                int errorCode = jsonObject.getInt("errcode");
                String errorMsg = jsonObject.getString("errmsg");
                log.error("创建永久带参二维码失败 errcode:{} errmsg:{}", errorCode, errorMsg);
            }
        }

        return shortURL;
    }
