HttpPost Cookies持久化Android

概述我想在发布请求后保存Cookie.httpClient实现的类：publicclassJSONParser{CookieStorestore=newBasicCookieStore();staticInputStreamis=null;staticJSONObjectjObj=null;staticStringjson="";privatestaticfin

我想在发布请求后保存cookie. httpClIEnt实现的类：

 public class JsONParser {    cookieStore store = new BasiccookieStore();       static inputStream is = null;        static JsONObject jObj = null;        static String Json = "";        private static final DefaulthttpClIEnt httpClIEnt = new DefaulthttpClIEnt() ;     public static DefaulthttpClIEnt getInstance() { return httpClIEnt; }    public JsONObject getJsONFromUrl(String url, List<nameValuePair> params) {        // Making http request        try {            cookieStore cookieStore = new BasiccookieStore();            // Create local http context            httpContext localContext = new BasichttpContext();            // Bind custom cookie store to the local context            localContext.setAttribute(ClIEntContext.cookie_STORE, cookieStore);            DefaulthttpClIEnt httpClIEnt = JsONParser.getInstance();            List<cookie> cookies = httpClIEnt.getcookieStore().getcookies();            httpClIEnt.getParams().setParameter(CoreProtocolPnames.USER_AGENT, "AndroID-AEApp,ID=2435743");            httpClIEnt.getParams().setParameter(ClIEntPnames.cookie_POliCY, cookiePolicy.RFC_2109);            httpPost httpPost = new httpPost(url);            httpPost.setEntity(new UrlEncodedFormEntity(params));            httpPost.setheader("User-Agent","AndroID-AEApp,ID=2435743");            cookies = httpClIEnt.getcookieStore().getcookies();            httpPost.setheader("Accept", "text/HTML,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8");            httpPost.setheader("cookie", "PHPSESSID=lc89a2uu0rj6t2p219gc2cq4i2; path=/");            httpResponse httpResponse = httpClIEnt.execute(httpPost);            httpentity httpentity = httpResponse.getEntity();            cookies = httpClIEnt.getcookieStore().getcookies();            if (cookies.isEmpty()) {                for (cookie a : cookies)                cookieStore.addcookie(a);            } else {                for (cookie a : cookies) {                    cookieStore.addcookie(a);                    System.out.println("- " + a.getValue().toString());                }            }            is = httpentity.getContent();        } catch (UnsupportedEnCodingException e) {            e.printstacktrace();        } catch (ClIEntProtocolException e) {            e.printstacktrace();        } catch (IOException e) {            e.printstacktrace();        }       }

我为DefaulthttpClIEnt创建singlotone,并希望将其用于其他请求.当我尝试使像这样：

 httpResponse httpResponse = httpClIEnt.execute(httpPost, localContext);

我没有饼干.当我不包括localContext时,我可以使用

 if (cookies.isEmpty()) {                for (cookie a : cookies)                cookieStore.addcookie(a);            } else {                for (cookie a : cookies) {                    cookieStore.addcookie(a);                    System.out.println("- " + a.getValue().toString());                }            }

但是cookie不会在第二个请求时设置.我猜-原因是不使用localContext.告诉我有什么问题,如果更改了cookie,如何设置cookie？

解决方法:

我对cookie的ArrayList使用了Singletone.看起来像这样：

public class cookieStorage {    private ArrayList<Object> arrayList;    private static cookieStorage instance;    private cookieStorage(){        arrayList = new ArrayList<Object>();    }    public static cookieStorage getInstance(){        if (instance == null){            instance = new cookieStorage();        }        return instance;    }    public ArrayList<Object> getArrayList() {        return arrayList;    }    @OverrIDe    public String toString()    {           return getArrayList().toString();       }}

和我的httpClIEnt类：

public class httpClIEnt {static inputStream is = null;private static final DefaulthttpClIEnt httpClIEnt = new DefaulthttpClIEnt() ;public static DefaulthttpClIEnt getInstance() { return httpClIEnt; } public static inputStream getResponse(String url, List<nameValuePair> params) {    try {    cookieStore cookieStore = new BasiccookieStore();    DefaulthttpClIEnt httpClIEnt = JsONParser.getInstance();            httpClIEnt.getParams().setParameter(CoreProtocolPnames.USER_AGENT, "AndroID-AEApp,ID=2435743");    httpClIEnt.getParams().setParameter(ClIEntPnames.cookie_POliCY, cookiePolicy.RFC_2109);    BasicclIEntcookie cookie = new BasicclIEntcookie("PHPSESSID", "1");      httpClIEnt.setcookieStore(cookieStore);    httpPost httpPost = new httpPost(url);    httpPost.setEntity(new UrlEncodedFormEntity(params));    httpPost.setheader("User-Agent","AndroID-AEApp,ID=2435743");    httpPost.setheader("Accept", "text/HTML,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8");    System.out.println(cookieStorage.getInstance().toString());    if (cookieStorage.getInstance().getArrayList().isEmpty())        cookieStorage.getInstance().getArrayList().add("PHPSESSID=lc89a2uu0rj6t2p219gc2cq4i2");    httpPost.setheader("cookie", cookieStorage.getInstance().getArrayList().get(0).toString());    httpResponse httpResponse = httpClIEnt.execute(httpPost);    header[] head = httpResponse.getAllheaders();    System.out.println(cookie);    if (httpResponse.getLastheader("Set-cookie")!=null)    {        cookieStorage.getInstance().getArrayList().remove(0);        cookieStorage.getInstance().getArrayList().add(httpResponse.getLastheader("Set-cookie").getValue());    }    Log.i("arrayList",(cookieStorage.getInstance().getArrayList().toString()));    httpentity httpentity = httpResponse.getEntity();    is = httpentity.getContent();    } catch (UnsupportedEnCodingException e) {        e.printstacktrace();    } catch (ClIEntProtocolException e) {        e.printstacktrace();    } catch (IOException e) {        e.printstacktrace();    }     return is; }}
