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

Use*_*er3 17 php java session android httpurlconnection

让我从我想要的开始:

我想制作一个应用程序part native and part webviews.

问题 - 维护本机和Webview部件之间的会话.

我处理这个的方法:

我打算实现一个本机登录,在其中我向用户提供两个EditTextboxes和一个按钮,用户输入凭据,我将它们作为JSON发布到服务器.

服务器响应成功或错误.基于Success标志,我读取了此连接的标头值并解压缩SessionCookie:

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();
            }

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);

我尝试了一种不同的方法,只是为了阅读HTML上面的webview URL:

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

            connection.setRequestProperty("Cookie", headerValue);

            connection.setRequestMethod("GET");

            connection.setDoOutput(true);


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

观察: Set-Cookie被打包在一起,有四个实例.

~~当我Advanced Rest Client手动尝试这一切时,一切正常.我得到了所需的HTML页面 - 经过身份验证.~~

观察: 该Advanced Rest Client应用程序提供了正确的结果,只有当我登录到该网站,在同一浏览器.基本上,cookie被覆盖了.

意见

我厌倦了试图从HttpUrlConnection获取会话cookie,我做的更改是加载webview并在其中登录.

其次,我设置了一个触发我的HttpUrlConnection的按钮 - 并尝试访问需要身份验证的页面.

在这个HttpUrlConnection里面,我做了类似这样的事情:

 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);

我最接近的是,通过使用webview作为登录.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();
    }
}
