java 实现微信小程序敏感内容检测（图片和文字

根据微信官方文档写了份适合的小程序敏感内容检查代码

直接上代码

// 获取token
public static String getAccessToken()
{
    String appId= "自己的";
    String secret="自己的";
    String accessToken="https://api.weixin.qq.com/cgi-bin/token";
    String turl = String.format(
            "%s?grant_type=client_credential&appid=%s&secret=%s", accessToken,
            appId, secret);
    HttpClient client = new DefaultHttpClient();
    HttpGet get = new HttpGet(turl);
    JsonParser jsonparer = new JsonParser();// 初始化解析json格式的对象
    String result = null;
    try
    {
        HttpResponse res = client.execute(get);
        String responseContent = null; // 响应内容
        HttpEntity entity = res.getEntity();
        responseContent = EntityUtils.toString(entity, "UTF-8");
        JsonObject json = jsonparer.parse(responseContent)
                .getAsJsonObject();
        // 将json字符串转换为json对象
        if (res.getStatusLine().getStatusCode() == HttpStatus.SC_OK)
        {
            if (json.get("errcode") != null)
            {// 错误时微信会返回错误码等信息，{"errcode":40013,"errmsg":"invalid appid"}
            }
            else
            {// 正常情况下{"access_token":"ACCESS_TOKEN","expires_in":7200}
                result = json.get("access_token").getAsString();
            }
        }
    }
    catch (Exception e)
    {
        e.printStackTrace();
    }
    finally
    {
        // 关闭连接 ,释放资源
        client.getConnectionManager().shutdown();
        return result;
    }
}

 * @return
 */
public  static List arrayToList(String blise) throws Exception{
    String str2 = blise.substring(1, blise.length());
    String strs=str2.substring(0,str2.length()-1);
    String[] strArr = strs.split(",");//注意分隔符是需要转译
    List urls=new ArrayList<>();
    for (int i = 0; i < strArr.length; i++) {
        String str3 = strArr[i].substring(1, strArr[i].length());
        String str4=str3.substring(0,str3.length()-1);
        urls.add(str4);
    }
    return   urls;
}
