微信域名检测源码(适合各种语言)

原理：利用微信重定向判断域名是否被封
javaer直接复制代码就可以运行
检测的域名必须添加 HTTP/HTTPS：

Pattern pattern = compile("^([hH][tT]{2}[pP]://|[hH][tT]{2}[pP][sS]://)(([A-Za-z0-9-~]+).)+([A-Za-z0-9-~\\/])+$");
    boolean matches = pattern.matcher(url).matches();
    if(!matches){
      return BaseResult.failed().msg("不合法的链接，请填写完整的链接地址(http://xxxx.com)！");
    }

话不多说直接上代码：

import cn.hutool.http.HttpRequest;
import cn.hutool.http.HttpResponse;
import cn.hutool.http.Method;
