Question

通过特定的localAddress

绑定HttpClient请求时出错

这是代码

    HttpParams httpsParams = new BasicHttpParams();
    ConnRouteParams.setLocalAddress(httpsParams, InetAddress.getByAddress(new byte[]{ (byte)192, (byte)168, (byte)43, (byte)98 }));

    DefaultHttpClient httpClient = new DefaultHttpClient(httpsParams);

    URL url = new URL("http://what-is-my-ip.net/?json");

    HttpGet method = new HttpGet(url.toURI());

    HttpResponse response = httpClient.execute(method);
    InputStream is = response.getEntity().getContent();

    ByteArrayOutputStream bos = new ByteArrayOutputStream();

    byte[] buffer = new byte[1024];
    int nbRead;
    while ((nbRead = is.read(buffer)) != -1) {
        bos.write(buffer, 0, nbRead);
    }

    is.close();

    System.out.println(new String(bos.toByteArray()));

这是错误

我做错了吗？请帮忙，我google了很多但却找不到任何相关内容。

这是与OS相关的问题吗，我在win7上？

任何帮助都将受到赞赏。

Sry，但无法评论问题，所以我会尽力回答： 99.1％的可能性在192.168.43.98接口中出现问题，检查它是否正常工作

PS：你可以通过curl测试它： curl --interface“192.168.43.98”http://what-is-my-ip.net/?json

将HttpClient 4.1请求绑定到本地地址
