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:
[Java] 纯文本查看 复制代码 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:
[Java] 纯文本查看 复制代码
