HttpPost Cookies持久化Android
作者:互联网
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;
}
}
