api图片鉴黄

1.账号准备

本文使用的是 UCloud 提供的 UAI-Censor，目前他支持图片，暴恐、涉政会陆续上线。他提供了每日2000张免费调用额度，所以无论对于测试还是小众的工具足够了。

1、使用如下链接注册账号

https://urlify.cn/Bj2Y3y

2、创建 UAI-Censor 应用

3、获取公钥、私钥，应用ID

https://console.ucloud.cn/uapi/apikey

4、编码

        ResponseEntity<String> responseEntity = rest.exchange(ucloudUrl, HttpMethod.POST, httpEntity, String.class);
        String body = responseEntity.getBody();
        System.out.println(body);
        JSONObject jsonObject = JSON.parseObject(body);
        if (jsonObject.getInteger("RetCode") == 0) {
            return jsonObject.getJSONObject("Result").getJSONObject("Porn").getString("Suggestion");
        }
        return null;
    }
