之前使用過XUtils框架做過項目，當時因爲session糾結了好久，但是解決了，現在回想起來，好像沒有備份，趕緊寫份筆記備份下，以後方便使用。

主要是登陸服務器後，應該保存一個登陸狀態，登陸後，會保存個登陸狀態，只有保存這個狀纔能有權限訪問對應的內容，否則，返回的是一堆html格式的網頁。

這時候，就會考慮到保存Cookie。直接上代碼吧：

這裏是登陸界面：

MainActivity.java對應的import

import org.apache.http.client.CookieStore;
import org.apache.http.cookie.Cookie;
import org.apache.http.impl.client.DefaultHttpClient;

MainActivity.java

private void httpLogin() {
        final HttpUtils http = new HttpUtils();
        RequestParams params = new RequestParams();
        String url = "http://192.168.1.60/auto/login_Login.action?oper.operatorName=123&oper.password=123";
        final String urlPost="http://192.168.1.60/auto/login_Login.action";
        params.addBodyParameter("oper.operatorName","123");
        params.addBodyParameter("oper.password","123");
        http.send(HttpRequest.HttpMethod.POST,
                urlPost,
                params,
                new RequestCallBack<String>() {

                    @Override
                    public void onStart() {
                        pg.show();
                        Log.d("jack",urlPost);
                    }

                    @Override
                    public void onLoading(long total, long current, boolean isUploading) {
                        pg.show();
                    }

                    @Override
                    public void onSuccess(ResponseInfo<String> responseInfo) {
                        pg.dismiss();
                        Log.d("jack",responseInfo.result);
                        //===========================
                        // 取得sessionid.........................

                        DefaultHttpClient dh = (DefaultHttpClient) http.getHttpClient();
                        MyCookieStore.cookieStore = dh.getCookieStore();
                        CookieStore cs = dh.getCookieStore();
                        List<Cookie> cookies = cs.getCookies();
                        String aa = null;
                        for (int i = 0; i < cookies.size(); i++) {
                            if ("JSESSIONID".equals(cookies.get(i).getName())) {
                                aa = cookies.get(i).getValue();
                                break;
                            }
                        }
                        Log.d("jack", "比較sessionid" + aa);
                        //===========================
                        Intent intent = new Intent(MainActivity.this,SecondActivity.class);
                        startActivity(intent);
                    }

                    @Override
                    public void onFailure(HttpException error, String msg) {
                        pg.dismiss();
                        Log.d("jack","哈哈"+msg);
                    }
            });
    }

關鍵代碼：

//===========================
                        // 取得sessionid.........................
                        DefaultHttpClient dh = (DefaultHttpClient) http.getHttpClient();
                        MyCookieStore.cookieStore = dh.getCookieStore();
                        CookieStore cs = dh.getCookieStore();
                        List<Cookie> cookies = cs.getCookies();
                        String aa = null;
                        for (int i = 0; i < cookies.size(); i++) {
                            if ("JSESSIONID".equals(cookies.get(i).getName())) {
                                aa = cookies.get(i).getValue();
                                break;
                            }
                        }
                        Log.d("jack", "比較sessionid" + aa);
                        //===========================

這裏面的MyCookieStore是自定義的一個保存類：

MyCookieStore.java

import org.apache.http.client.CookieStore;

public class MyCookieStore {

    public static CookieStore cookieStore=null;
    
}

最後就是在登陸後訪問服務器的時候添加一句話：

http.configCookieStore(MyCookieStore.cookieStore);

給個類裏的代碼看看吧：

SecondActivity.java

private void httpLogin() {
        HttpUtils http = new HttpUtils();
        final String urlGet="http://192.168.1.60/auto/carModel_queryPL.action";
        http.configCookieStore(MyCookieStore.cookieStore);
        http.send(HttpRequest.HttpMethod.POST,
                urlGet,
                new RequestCallBack<String>() {

                    @Override
                    public void onStart() {
                        pg.show();
                        Log.d("jack",urlGet);
                    }

                    @Override
                    public void onLoading(long total, long current, boolean isUploading) {
                        pg.show();
                    }

                    @Override
                    public void onSuccess(ResponseInfo<String> responseInfo) {
                        pg.dismiss();
                        Log.d("jack","排量"+responseInfo.result);
                    }

                    @Override
                    public void onFailure(HttpException error, String msg) {
                        pg.dismiss();
                        Log.d("jack","排量"+msg);
                    }
            });
    }
