Question

以下一段代码在过去三年中一直在运行，但突然间它只在服务器中抛出连接超时，但在localhost中按预期工作。有什么意见吗？

    public  String getWikiContent(String query) {
    StringBuilder builder = new StringBuilder();

    String path = "https://en.wikipedia.org/w/api.php?action=query&prop=extracts&exintro=1&explaintext=1&titles=" + query + "&format=json&redirects";
    try {
        URL url = new URL(path);

        HttpURLConnection urlConn = (HttpURLConnection) url.openConnection();
        urlConn.setRequestProperty("Content-Type",
                "application/json");

        if (urlConn.getResponseCode() != 200) {
            throw new IOException(urlConn.getResponseMessage());
        }

        InputStream is = urlConn.getInputStream();
        BufferedReader buff = new BufferedReader(new InputStreamReader(is));
        String line;

        while ((line = buff.readLine()) != null) {
            builder.append(line);
        }
    }catch (IOException e){
        e.printStackTrace();
    }
    return builder.toString();
   }

由于某些原因，它是一个网络问题，只需添加一个代理服务器修复它。

Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress(url,port));
URLConnection urlConn = url.openConnection(proxy);

连接仅在服务器上为wikmedia api超时，但在本地工作
