    public static void main(String[] args) {

                .form("langType", "auto")
                .form("img", base64Image)
                .form("docType", "json")
                .form("signType", "v3")
                .form("curtime", curTime)

        try (HttpResponse response = request.execute()) {
            Console.log(response.body());
        }
    }

    private static String truncate(String q) {
        if (q == null) {
            return null;
        }
        int len = q.length();
        return len <= 20 ? q : (q.substring(0, 10) + len + q.substring(len - 10, len));
    }
}

配置文件如下：

YOU_DAO_OCR_URL = https://openapi.youdao.com/ocrapi
YOU_DAO_APP_KEY = <YOUR_YOU_DAO_APP_KEY>
YOU_DAO_APP_SECRET = <YOUR_YOU_DAO_APP_SECRET>

执行结果如下：
