获取微信分享签名

1、微信公众号绑定分享的域名

2、加上ip白名单

3、有一个MP_verify_EM2V8QaIKnqw5Ts2.txt 将该文件放在机器下

4、编写获取微信分享的接口

public String get(String url) {
    BufferedReader in = null;
    try {
       //微信的httpUrl:http://XXX/x-thirdparty-web/weixinJssdk/config?signatureUrl=

        in = new BufferedReader(new InputStreamReader(HttpClientUtils.get(config.getWeixinHttpUrl() + url + "&thirdpartyId=XXX")));
        StringBuffer sb = new StringBuffer();
        String line;
        while ((line = in.readLine()) != null) {
            sb.append(line);
        }
        return sb.toString();
    } catch (Exception e) {
        logger.error("Exception occur when send http get request!", e);
    }
    // 使用finally块来关闭输入流
    finally {
        try {
            if (in != null) {
                in.close();
            }
        } catch (Exception e2) {
            e2.printStackTrace();
        }
    }
    return null;
}
