Question

我正在尝试点击网络服务。它与android 4.4或android 5.X一起正常工作。但是当我试图使用android 4.1.1命中＆＃34; http://inmotion-prod.cloudapp.net:145/service1.svc/json/GetCustomerUUID"时，它总是返回307状态代码。但是这个url在android 4.4或5.x下工作正常。我也尝试打其他网址它在Android 4.1.1上工作正常。所以请告诉我这是什么问题

Log.i(TAG, url);
        String response = null;
        HttpURLConnection conn = null;
        try {
            URL webServiceUrl = new URL(url);
            conn = (HttpURLConnection) webServiceUrl
                    .openConnection();
            Log.i(TAG, "Connection open");
            conn.setRequestMethod(GET);
            conn.setConnectTimeout(CONNECTION_TIME_OUT);
            conn.setRequestProperty(CONTENT_TYPE, contentType);
            conn.setRequestProperty(ACCEPT_TYPE, acceptType);
            conn.setDoInput(true);
            conn.connect();
            Log.i(TAG, "Connection Connected");

            if (conn.getResponseCode() == HttpURLConnection.HTTP_OK && conn.getInputStream() != null) {
                response = StreamUtility.convertStreamToString(conn.getInputStream());
                conn.getInputStream().close();
            }

        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            if (conn != null) {
                conn.disconnect();
            }
        }

        return response;
    }

将您的网址替换为http://inmotion-prod.cloudapp.net:145/service1.svc/json/GetCustomerUUID/（请注意最后的/）。响应代码为200。

<强>更新

使用最后没有http://inmotion-prod.cloudapp.net:145/service1.svc/json/GetCustomerUUID的当前网址（/），您可以使用以下代码：

String address = "http://inmotion-prod.cloudapp.net:145/service1.svc/json/GetCustomerUUID";
URL url = new URL(address);
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setInstanceFollowRedirects(false);
// if print out (debug or logging), you will see secondURL has / at the end
URL secondURL = new URL(urlConnection.getHeaderField("Location"));
HttpURLConnection urlConnection1 = (HttpURLConnection) secondURL.openConnection();

然后使用urlConnection1.getResponseCode()

希望它有所帮助！

BNK的回答有所帮助，我修复了这个问题，以便它也适用于较新的设备（位置标题返回为null / empty！）

String headerLocation = httpsUrlConnection.getHeaderField("Location");
logger.debug("Location header: " + headerLocation);

// if the redirect URL ends with a "/" sign, but the original URL does not, it's probably the redirect bug
String originalURL = url.toString();
if (!TextUtils.isEmpty(headerLocation) && headerLocation.endsWith("/") && !originalURL.endsWith("/"))
    {
    logger.info("Redirect Location differs from original URL, create new connection to: " + headerLocation);
    httpsUrlConnection = (HttpsURLConnection) new URL(headerLocation).openConnection();

    // optional
    httpsUrlConnection.setSSLSocketFactory(sslSocketFactory);
    }

HttpConnectionUrl始终返回状态代码307
