维护 HttpUrlConnection 调用之间的会话（本机/Web 视图）

php android java session httpurlconnection
2022-08-30 22:17:05

让我从我想要的开始：

我想做一个应用程序，它是.part native and part webviews

问题 - 维护本机部件和 Web 视图部件之间的会话。

我的处理方法：

我打算实现一个本机登录，其中我向用户显示两个EditTextbox和一个按钮，用户输入凭据并将其作为JSON发布到服务器。

服务器以成功或错误的方式响应。根据成功标志，我读取此连接的标头值并提取会话Cookie：

switch (responseCode) {
                case 200:

                    BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
                    String inputLine;
                    response = new StringBuffer();
                    while ((inputLine = in.readLine()) != null) {
                        response.append(inputLine);
                    }
                    in.close();

                   //IF SUCCESS

                    Map<String, List<String>> map = conn.getHeaderFields();

                    for (Map.Entry<String, List<String>> entry : map.entrySet()) {
                        System.out.println("Key : " + entry.getKey() + " ,Value : " + entry.getValue());
                    }

                    SSID = map.get("Set-Cookie").toString();
                    SSID = SSID.substring(1,SSID.length()-1);
                    return response.toString();
            }

和它看起来像下面：

Set-Cookie ,Value : [PHPSESSID=e407ef64abb71b1ea2b8e4b30db76cf0; path=/, ci_session=a%3A0%3A%7B%7D; expires=Thu, 06-Nov-2014 16:54:57 GMT; Max-Age=-31500000; path=/, ci_session=a%3A5%3A%7Bs%3A10%3A%22session_id%22%3Bs%3A32%3A%22caedca696344458e7aa1b4ad02b3cfa0%22%3Bs%3A10%3A%22ip_address%22%3Bs%3A13%3A%22182.59.130.42%22%3Bs%3A10%3A%22user_agent%22%3Bs%3A60%3A%22Dalvik%2F2.1.0+%28Linux%3B+U%3B+Android+5.1.1%3B+Nexus+5+Build%2FLMY48B%29%22%3Bs%3A13%3A%22last_activity%22%3Bi%3A1446792897%3Bs%3A9%3A%22user_data%22%3Bs%3A0%3A%22%22%3B%7D5f4013e4a2edd2eb891ec8a2b8e8716e; expires=Sun, 05-Nov-2017 06:54:57 GMT; Max-Age=63072000; path=/, ci_session=a%3A4%3A%7Bs%3A10%3A%22session_id%22%3Bs%3A32%3A%22caedca696344458e7aa1b4ad02b3cfa0%22%3Bs%3A10%3A%22ip_address%22%3Bs%3A13%3A%22182.59.130.42%22%3Bs%3A10%3A%22user_agent%22%3Bs%3A60%3A%22Dalvik%2F2.1.0+%28Linux%3B+U%3B+Android+5.1.1%3B+Nexus+5+Build%2FLMY48B%29%22%3Bs%3A13%3A%22last_activity%22%3Bi%3A1446792897%3B%7Dc7eaa0945a7056db3cb9d336a02e5ecb; expires=Sun, 05-Nov-2017 06:54:57 GMT; Max-Age=63072000; path=/, ci_session=a%3A4%3A%7Bs%3A10%3A%22session_id%22%3Bs%3A32%3A%22caedca696344458e7aa1b4ad02b3cfa0%22%3Bs%3A10%3A%22ip_address%22%3Bs%3A13%3A%22182.59.130.42%22%3Bs%3A10%3A%22user_agent%22%3Bs%3A60%3A%22Dalvik%2F2.1.0+%28Linux%3B+U%3B+Android+5.1.1%3B+Nexus+5+Build%2FLMY48B%29%22%3Bs%3A13%3A%22last_activity%22%3Bi%3A1446792897%3B%7Dc7eaa0945a7056db3cb9d336a02e5ecb; expires=Sun, 05-Nov-2017 06:54:57 GMT; Max-Age=63072000; path=/]

警告：在上面expires=Thu, 06-Nov-2014 16:54:57 GMT

现在我想转到Webview并将此cookie添加到标题中，我正在这样做：

Map<String, String> abc = new HashMap<String, String>();
            abc.put("Cookie", UniversalHttpUrlConnection.SSID);
            webView.loadUrl("https://someUrl/show_all", abc);

但是，上述方法不起作用。

我尝试了另一种方法，只是为了从上面的webview URL中读取：HTML

 public static String doHttpUrlConnectionAction(String desiredUrl, String headerValue)
            throws Exception {
        URL url = null;
        BufferedReader reader = null;
        StringBuilder stringBuilder;

        try {

            url = new URL(desiredUrl);
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setRequestProperty("Cookie", headerValue);

            connection.setRequestMethod("GET");

            connection.setDoOutput(true);


            connection.setReadTimeout(15 * 1000);
            connection.connect();


            reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
            stringBuilder = new StringBuilder();

            String line = null;
            while ((line = reader.readLine()) != null) {
                stringBuilder.append(line + "\n");
            }
            return stringBuilder.toString();
        } catch (Exception e) {
            e.printStackTrace();
            throw e;
        } finally {

            if (reader != null) {
                try {
                    reader.close();
                } catch (IOException ioe) {
                    ioe.printStackTrace();
                }
            }
        }

    }

我得到的HTML是登录页面的HTML，它本质上是一个重定向 - 因为服务器无法识别会话并重定向我。我在这里错过了什么？如何继续会话？

编辑 - 进一步调试：

使用已弃用的：

HttpClient httpClient = new DefaultHttpClient(); //

我得到这些标题：

观察：Set-Cookie打包在一起，四个实例。

当我在高级休息客户端手动尝试此操作时，一切正常。我得到了所需的HTML页面 - 经过身份验证。

观察：只有当我在同一浏览器中登录到网站时，该应用程序才会给出正确的结果。所以基本上饼干被覆盖了。Advanced Rest Client

观察

我厌倦了尝试从HttpUrlConnection获取会话cookie，我所做的更改是加载Web视图并在其中登录。

其次，我竖起了一个按钮，可以触发我的HttpUrlConnection - 并尝试访问需要身份验证的页面。

在这个HttpUrlConnection内部，我做了这样的事情：

 CookieManager cookieManager = CookieManager.getInstance();
            String cookie = cookieManager.getCookie(new URL("https://urlinQuestion.com").getHost());
            System.out.println("Cookie from cookie store" + cookie);
            connection.setRequestProperty("Cookie", cookie);

所以我把我在webView中得到的cookie传递给HttpUrlCOnnection。它的工作原理。现在我觉得为了颠倒事件的顺序（因为我想要从UrlConnection中获取cookie - 将它们传递到webview），我将不得不更新cookie管理器。（新航程从这里开始）

为了记录起见，我在下面添加了两个cookie：第一个不起作用，第二个我从Webview方式和工作中获得，我发现语义没有区别：

PHPSESSID=a3d2367f8a5a3221e9bad1a91a34fd55; ci_session=a%3A4%3A%7Bs%3A10%3A%22session_id%22%3Bs%3A32%3A%221381c152699fb61d04663c9b854ecdd7%22%3Bs%3A10%3A%22ip_address%22%3Bs%3A14%3A%22182.59.245.196%22%3Bs%3A10%3A%22user_agent%22%3Bs%3A60%3A%22Dalvik%2F2.1.0+%28Linux%3B+U%3B+Android+5.1.1%3B+Nexus+5+Build%2FLMY48B%29%22%3Bs%3A13%3A%22last_activity%22%3Bi%3A1447140920%3B%7Ddd2c014724b9ca061b50774f1fea235d

答案 1

我能达到的最接近这一点的是，使用Webview作为登录名。然后，您可以在HttpUrlConnection中继续您的会话，并从webview获取cookie。Cookie 可以按如下方式使用：

HttpURLConnection urlConnection = null;
try {
    urlConnection = (HttpURLConnection) url.openConnection();

    // Fetch and set cookies in requests
    CookieManager cookieManager = CookieManager.getInstance();
    String cookie = cookieManager.getCookie(urlConnection.getURL().toString());
    if (cookie != null) {
        urlConnection.setRequestProperty("Cookie", cookie);
    }
    urlConnection.connect();

    // Get cookies from responses and save into the cookie manager
    List cookieList = urlConnection.getHeaderFields().get("Set-Cookie");
    if (cookieList != null) {
        for (String cookieTemp : cookieList) {
            cookieManager.setCookie(urlConnection.getURL().toString(), cookieTemp);
        }
    }

    InputStream in = new BufferedInputStream (urlConnection.getInputStream());
} catch (IOException e) {
    e.printStackTrace();
} finally {
    if (urlConnection != null) {
        urlConnection.disconnect();
    }
}

答案 2

它应该在请求上发送的标头，而不是 。
有关示例，请阅读 https://www.rfc-editor.org/rfc/rfc6265。CookieSet-Cookie

当客户端在 HTTP 响应标头中收到会话 Cookie 时，如下所示

Set-Cookie: PHPSESSID=e407ef64abb71b1ea2b8e4b30db76cf0; path=/

它应该将此 cookie 添加到后续的 HTTP 请求标头中，作为

Cookie: PHPSESSID=e407ef64abb71b1ea2b8e4b30db76cf0

编辑：

本机有点令人困惑，但是使用cookie的最后一个值应该是可以的，例如从响应PHPSESSIDci_session

添加到 webview 请求的 folowing 标头中：

abc.put("Cookie", "ci_session=a%3A4%3A%7Bs%3A10%3A%22session_id%22%3Bs%3A32%3A%2221d4f88af57e9c7477f48e0695bdb979%22%3Bs%3A10%3A%22ip_address%22%3Bs%3A13%3A%22182.59.216.32%22%3Bs%3A10%3A%22user_agent%22%3Bs%3A40%3A%22Apache-HttpClient%2FUNAVAILABLE+%28java+1.4%29%22%3Bs%3A13%3A%22last_activity%22%3Bi%3A1446884548%3B%7D30e2cc6561b3fb9659c7809d0c82946d");

我建议迭代，用正则表达式之类的东西测试每个单独的'Set-Cookie'标头，并返回最后一个匹配项。SSID = map.get("Set-Cookie")/(ci_session=.*?);/

请注意，Web 视图中的标头应在会话中匹配。在上面的cookie中，它是，似乎webview使用.User-Agentuser_agentApache-HttpClient/UNAVAILABLE (java 1.4)Dalvik/2.1.0 (Linux; U; Android 5.1.1; Nexus 5 Build/LMY48B)
