HttpURLConnection:在一些android设备和模拟器中获得307响应代码

HttpURLConnection:在一些android设备和模拟器中获得307响应代码,android,httpurlconnection,http-status-codes,Android,Httpurlconnection,Http Status Codes,我正在使用HttpURLConnection执行对特定URL的GET请求。在一些模拟器和设备中,它工作得很好,我得到了200个代码,在另一些设备中我得到了307个代码。有人能告诉我问题出在哪里吗 这是我的密码: URL cnx = new URL(url); HttpURLConnection urlCon = (HttpURLConnection) cnx.openConnection(); urlCon.setRequestMethod("GET"); urlCon.setConnect

我正在使用
HttpURLConnection
执行对特定URL的GET请求。在一些模拟器和设备中,它工作得很好,我得到了200个代码,在另一些设备中我得到了307个代码。有人能告诉我问题出在哪里吗

这是我的密码:

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。如果有人有同样的问题,下面是代码:

公共字符串WebServiceCall(字符串url){


307是临时重定向。无法说明它发生的原因,但通常大多数http客户端都可以“自动”执行这些重定向。您是否尝试将代码放入线程中?实际上,我正在将代码放入线程中。
    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;
}
