Android 上的 HttpClient 的 Cookie 存取策略

`BasicHttpParams params = ``new` `BasicHttpParams();`

`// Set the timeout in milliseconds until a connection is established. `

`HttpConnectionParams.setConnectionTimeout(params, TIMEOUT_CONNECTION);`

`// Set the default socket timeout (SO_TIMEOUT) `

`// in milliseconds which is the timeout for waiting for data. `

`HttpConnectionParams.setSoTimeout(params, TIMEOUT_SOCKET); `

`ConnManagerParams.setMaxTotalConnections(params, ``5``);`

`ConnManagerParams.setTimeout(params, TIMEOUT_TOTAL);`

`client = ``new` `DefaultHttpClient(params);`

`CookieStore cookieStore = ``new` `BasicCookieStore();`

`//Bind custom cookie store to the local context`

`client.setCookieStore(cookieStore);`

`CookieSpecFactory csf = ``new` `CookieSpecFactory() { `

`public` `CookieSpec newInstance(HttpParams params) {`

` ``return` `new` `BrowserCompatSpec() {`

` ``@Override`

` ``public` `void` `validate(Cookie cookie, CookieOrigin origin) ``throws` `MalformedCookieException `

` ``{`

` ``// Oh, I am easy`

` ``// allow all cookies`

` ``//log.debug("custom validate");`

` ``}`

` ``};`

`}`

`};`

`client.getCookieSpecs().register(``"oschina"``, csf);`

`client.getParams().setParameter(ClientPNames.COOKIE_POLICY, ``"oschina"``);`

`client.getParams().setParameter(CookieSpecPNames.SINGLE_COOKIE_HEADER, ``true``);`

当然下面设置也可以，直接运行下就能看到结果。。
