public static String getHtmlCode(String path) { String result = null; try { HttpClient httpclient = getHttpClient(); HttpGet get = new HttpGet(path); HttpResponse response = httpclient.execute(get); if (response.getStatusLine().getStatusCode() == HttpStatus.SC_OK) { HttpEntity entity = response.getEntity(); BufferedReader br = new BufferedReader(new InputStreamReader(entity.getContent(), "utf-8")); String line; result = ""; while ((line = br.readLine()) != null) { result += line + "\n"; } } } catch(ConnectTimeoutException e) { System.out.println("ConnectTimeoutException timeout"); return null; } catch (SocketTimeoutException e) { System.out.println("SocketTimeoutException timeout"); return null; } catch (Exception e) { System.out.println(e.getMessage() + ":" + e.toString()); return null; } return result; } }我哪里错了？修改结果

这段代码也是使用的过时的HTTPClient，同样可能会导致编译错误。你可以使用OkHttp来实现相同的功能，如下所示：

public static String getHtmlCode(String path) {
    String result = null;
    OkHttpClient client = getHttpClient();
    try {
        Request request = new Request.Builder()
                .url(path)
                .build();
        Response response = client.newCall(request).execute();
        if (response.isSuccessful()) {
            result = response.body().string();
        }
    } catch (ConnectTimeoutException e) {
        System.out.println("ConnectTimeoutException timeout");
        return null;
    } catch (SocketTimeoutException e) {
        System.out.println("SocketTimeoutException timeout");
        return null;
    } catch (Exception e) {
        System.out.println(e.getMessage() + ":" + e.toString());
        return null;
    }
    return result;
}

这个代码使用OkHttp的Request和Response对象来获取HTML代码，并且也支持设置连接和读取超时时间。使用OkHttp可以更加方便地实现HTTP请求，同时也支持HTTP/2和HTTP/1.1协议。
