HttpURLConnection：在某些 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 URL 执行 GET 请求。在某些模拟器和设备中，它工作得很好，我得到了 200 个代码，在其他模拟器和设备中，我得到了 307 个代码。有人可以告诉我问题是什么吗？

这是我的代码：

URL cnx = new URL(url); 
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; 
}

我已经通过使用 DefaultHttpClient 而不是 HttpURLConnection 解决了我的问题。如果有人遇到同样的问题，这里是代码：

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;
}
