Google、Facebook第三方登录获取用户信息超时

Question

最近有个需求就是集成Google和facebook登录，我这边就是拿着前端发来的accesstoken去调用Google获取facebook的api获取用户信息，进行个注册，但是在后端发送请求时，显示超时，但是我用postman都可以获取到

public static String sendGet(String url) 
    {
        System.out.println(url);
        String result = "";
        BufferedReader in = null;
        try {
            String urlNameString = url;
            URL realUrl = new URL(urlNameString);
            // 打开和URL之间的连接
            URLConnection connection = realUrl.openConnection();
            // 设置通用的请求属性
            connection.setRequestProperty("accept", "*/*");
            connection.setRequestProperty("connection", "Keep-Alive");
            connection.setRequestProperty("user-agent",
                    "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1;SV1)");
            // 建立实际的连接
            connection.connect();
            // 获取所有响应头字段

            // 定义 BufferedReader输入流来读取URL的响应
            in = new BufferedReader(new InputStreamReader(
                    connection.getInputStream()));
            String line;
            while ((line = in.readLine()) != null) {
                result += line;
            }
            in.close();
        } catch (Exception e) {
            try {
                if (in != null) {
                    in.close();
                }
            } catch (Exception e2) {
                return null;
            }
            e.printStackTrace();
            return null;
        }
        return result;
    }
public static void facebookAuth(String token)
    {
        String url = "https://graph.facebook.com/me?access_token="+token;
        
        System.err.println(sendGet(url));
    }

public static void main(String[] args) throws GeneralSecurityException, IOException 
    {
        
        facebookAuth("EAAGMf76DDU8BAIaO3MSQZBNksZCqfmlIHsIH1rJsvhl3jZCFYFPuZA6FZCQJAJGZBeZCnPJpUB0u504LbZBYP5ElJyz0B09AavAOKSIzwcdJKVL5bXDpIhaDNSIMbz1Wow6sriOtmXL6yhplkiSeutenkRvalcKgNDSUnZBuFtS02tX4G7r31pLt38mD0zgzalU6Nb76TojTKz0l3vaGzZCTcPwX29JBGHNkkSZA1uhyq3ZBHgZDZD");


    }

运行结果

我怀疑是不是没翻q的原因，结果用了还是一样的，但是我用postman就可以获取到信息，或者说idea里要发送https请求，要ssl证书？我也尝试了也没用

求能者帮忙，困扰好几天了，弄不出来怕是要走人了5555555555555555555555555555

先查看一下前端接口请求定义的时间为多久超时，可以试着增加请求时间
