HttpURLConnection：在一些Android设备和模拟器中获取307响应代码

Question

我正在使用HttpURLConnection对特定网址执行GET请求。在一些仿真器和设备中，它运行良好，我得到200代码，在其他情况下，我得到307代码。有人可以告诉我这是什么问题吗？

这是我的代码：

URL cnx =新网址（网址）; HttpURLConnection urlCon =（HttpURLConnection）cnx.openConnection（）; urlCon.setRequestMethod（ “GET”）; urlCon.setConnectTimeout（（int）timeout）; urlCon.setReadTimeout（（int）timeout）; urlCon.connect（）; int code = urlCon.getResponseCode（）; if（code！= 200）{return null; }

我通过使用DefaultHttpClient而不是HttpURLConnection解决了我的问题。如果有人遇到同样的问题，这是代码：

public String WebServiceCall（String url）{

    try {

        DefaultHttpClient httpClient = new DefaultHttpClient();
        HttpGet httpGet = new HttpGet(url);

        HttpResponse httpResponse = httpClient.execute(httpGet);
        HttpEntity httpEntity = httpResponse.getEntity();
        is = httpEntity.getContent();

    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    } catch (ClientProtocolException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }

    try {
        BufferedReader reader = new BufferedReader(new InputStreamReader(
                is, "utf-8"), 8);
        StringBuilder sb = new StringBuilder();
        String line = null;
        while ((line = reader.readLine()) != null) {
            sb.append(line);
        }
        is.close();
        res = sb.toString();

    } catch (Exception e) {
        Log.e("Buffer Error", "Error converting result " + e.toString());
    }

    return res;
}
