Java代理IP报错405

我在请求一个别的网站接口数据的时候，设置了代理，但是报错405，具体信息如下，我查了很多信息说是把POST改成GET就可以了，这个对我的代码没有任何作用，最令人头疼的是如果我仅仅是把“HttpURLConnection conn = (HttpURLConnection) realUrl.openConnection(proxy);”中的“proxy”去掉的话，代码就会成功运行，没有任何报错，并且可以成功拿到想要的数据，我想知道要怎么样才能够用代理访问成功

        URL realUrl = new URL(Constant.Url.POWER);
        Proxy proxy = new Proxy(Proxy.Type.HTTP,new InetSocketAddress("3.23.44.179",80));
        // 打开和URL之间的连接
        HttpURLConnection conn = (HttpURLConnection) realUrl.openConnection(proxy);
        //设置消息头
        setConnParam(conn);
        //获取参数
        String param = Tool.getResourceString(Constant.Path.PARAM);
        //获取返回体
        String result = Tool.getReturnBody(conn,param);
        if(result == null || "".equals(result.trim())){
            System.out.println("未获取到信息！");
            return;
        }
        response.getWriter().write(result);

//工具类报错代码
public static String getReturnBody(HttpURLConnection conn, String param) throws IOException {
        String result = "";
        PrintWriter out = null;

        // 获取URLConnection对象对应的输出流
        out = new PrintWriter(conn.getOutputStream());
        if(param == null){
            param = "";
        }
        // 发送请求参数
        out.print(param);
        // flush输出流的缓冲
        out.flush();
    }

很明显就是你的代理这块设置的有问题.你的代理是购买的还是网上找的,感觉这个代理的设置不太对劲,你debug看下在new Proxy的时候是不是就已经报错了
