Java Android会话管理

是否有特定的Android会话管理库？我需要在一个普通的Android应用程序中管理我的会话。不在

WebView

中。我可以通过post方法设置会话。但当我发送另一个请求时，会话将丢失。有人能帮我处理这件事吗

DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("My url");

HttpResponse response = httpClient.execute(httppost);
List<Cookie> cookies = httpClient.getCookieStore().getCookies();

if (cookies.isEmpty()) {
    System.out.println("None");
} else {
    for (int i = 0; i < cookies.size(); i++) {
        System.out.println("- " + cookies.get(i).toString());
    }
}

我得到了登录页面的响应正文。

这与Android无关。它与ApacheHttpClient有关，ApacheHttpClient是用于HTTP访问的库

会话cookie存储在

DefaultHttpClient

对象中。不要为每个请求创建一个新的

DefaultHttpClient

，而是保留它并重用它，您的会话cookie将得到维护

您可以阅读ApacheHttpClient和HttpClient中的cookie管理。

这是我在帖子中使用的内容。我可以使用此方法使用新的

httpClients

，其中

phpsessid

是使用上述代码从登录脚本中提取的

PHP

会话id

ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();

nameValuePairs.add(new BasicNameValuePair("PHPSESSID",phpsessid));

ArrayList nameValuePairs=新的ArrayList（）；
添加（新的BasicNameValuePair（“PHPSESSID”，PHPSESSID））；

通常，在Java HttpURLConnection中，您可以通过这种方式设置/获取cookie（以下是整个连接过程）。下面的代码位于我的ConnectionRead的run（）中，所有连接活动类都从中继承。所有共享与所有请求一起发送的公共静态sCookie字符串。因此，您可以保持登录/关闭等常见状态：

        HttpURLConnection conn = (HttpURLConnection) url.openConnection();             

        //set cookie. sCookie is my static cookie string
        if(sCookie!=null && sCookie.length()>0){
            conn.setRequestProperty("Cookie", sCookie);                  
        }

        // Send data
        OutputStream os = conn.getOutputStream(); 
        os.write(mData.getBytes());
        os.flush();
        os.close(); 

        // Get the response!
        int httpResponseCode = conn.getResponseCode();         
        if (httpResponseCode != HttpURLConnection.HTTP_OK){
           throw new Exception("HTTP response code: "+httpResponseCode); 
        }

        // Get the data and pass them to the XML parser
        InputStream inputStream = conn.getInputStream();                
        Xml.parse(inputStream, Xml.Encoding.UTF_8, mSaxHandler);                
        inputStream.close();

        //Get the cookie
        String cookie = conn.getHeaderField("set-cookie");
        if(cookie!=null && cookie.length()>0){
            sCookie = cookie;              
        }

        /*   many cookies handling:                  
        String responseHeaderName = null;
        for (int i=1; (responseHeaderName = conn.getHeaderFieldKey(i))!=null; i++) {
            if (responseHeaderName.equals("Set-Cookie")) {                  
            String cookie = conn.getHeaderField(i);   
            }
        }*/                

        conn.disconnect();

在Android应用程序中保持会话活动（用户登录或其他）的完全透明方式。 它在单例和HttpRequest/Response拦截器中使用apachedefaulthttpclient

SessionKeeper类只检查其中一个头是否设置为Cookie，如果设置为Cookie，它只会记住它。 SessionAdder只是将会话id添加到请求中（如果不是null）。 这样，您就可以知道整个身份验证过程是完全透明的

public class HTTPClients {

    private static DefaultHttpClient _defaultClient;
    private static String session_id;
    private static HTTPClients _me;
    private HTTPClients() {

    }
    public static DefaultHttpClient getDefaultHttpClient(){
        if ( _defaultClient == null ) {
            _defaultClient = new DefaultHttpClient();
            _me = new HTTPClients();
            _defaultClient.addResponseInterceptor(_me.new SessionKeeper());
            _defaultClient.addRequestInterceptor(_me.new SessionAdder());
        }
        return _defaultClient;
    }

    private class SessionAdder implements HttpRequestInterceptor {

        @Override
        public void process(HttpRequest request, HttpContext context)
                throws HttpException, IOException {
            if ( session_id != null ) {
                request.setHeader("Cookie", session_id);
            }
        }

    }

    private class SessionKeeper implements HttpResponseInterceptor {

        @Override
        public void process(HttpResponse response, HttpContext context)
                throws HttpException, IOException {
            Header[] headers = response.getHeaders("Set-Cookie");
            if ( headers != null && headers.length == 1 ){
                session_id = headers[0].getValue();
            }
        }

    }
}

非常感谢你。。我会试试的谢谢你的软件，它真的解决了我的问题。非常感谢……：）此链接给出了如何实现此功能的想法

public class HTTPClients {

    private static DefaultHttpClient _defaultClient;
    private static String session_id;
    private static HTTPClients _me;
    private HTTPClients() {

    }
    public static DefaultHttpClient getDefaultHttpClient(){
        if ( _defaultClient == null ) {
            _defaultClient = new DefaultHttpClient();
            _me = new HTTPClients();
            _defaultClient.addResponseInterceptor(_me.new SessionKeeper());
            _defaultClient.addRequestInterceptor(_me.new SessionAdder());
        }
        return _defaultClient;
    }

    private class SessionAdder implements HttpRequestInterceptor {

        @Override
        public void process(HttpRequest request, HttpContext context)
                throws HttpException, IOException {
            if ( session_id != null ) {
                request.setHeader("Cookie", session_id);
            }
        }

    }

    private class SessionKeeper implements HttpResponseInterceptor {

        @Override
        public void process(HttpResponse response, HttpContext context)
                throws HttpException, IOException {
            Header[] headers = response.getHeaders("Set-Cookie");
            if ( headers != null && headers.length == 1 ){
                session_id = headers[0].getValue();
            }
        }

    }
