Android 使用httpPost和httpclient持久化cookie
我有一个向Web服务发送请求的类Android 使用httpPost和httpclient持久化cookie,android,cookies,http-post,httpclient,cookiestore,Android,Cookies,Http Post,Httpclient,Cookiestore,我有一个向Web服务发送请求的类 public class JSONParser { CookieStore store = new BasicCookieStore(); static InputStream is = null; static JSONObject jObj = null; static String json = ""; private static final DefaultHttpClient httpClient = new Defaul
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();
}
}
然后我会收到新请求的cookies。当我尝试更新它们时,它会使用旧的。如果服务器更改了cookie,我如何更新cookie 问题解决了。我用单音作为我的曲奇列表。看起来是这样的:
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();
}
}
在请求执行之后:
httpResponse = client.execute(request);
if (httpResponse.getLastHeader("Set-Cookie")!=null)
{
CookieStorage.getInstance().getArrayList().remove(0);
CookieStorage.getInstance().getArrayList().add(httpResponse.getLastHeader("Set-Cookie").getValue());
}
这里你真的是指JSONParser:DefaultHttpClient-httpClient=JSONParser.getInstance();你从哪里获得PHPSSID??in:httpPost.setHeader(“Cookie”,“PHPSESSID=lc89a2uuu0rj6t2p292199gc2cq4i2;path=/”;
if (CookieStorage.getInstance().getArrayList().isEmpty())
CookieStorage.getInstance().getArrayList().add("PHPSESSID=lc89a2uu0rj6t2p219gc2cq4i2");
RestClient.this.AddHeader("Cookie", CookieStorage.getInstance().getArrayList().get(0).toString());
httpResponse = client.execute(request);
if (httpResponse.getLastHeader("Set-Cookie")!=null)
{
CookieStorage.getInstance().getArrayList().remove(0);
CookieStorage.getInstance().getArrayList().add(httpResponse.getLastHeader("Set-Cookie").getValue());
}
