本文详细介绍了如何使用默认HTTP客户端进行HTTP请求，并通过自定义Cookie策略管理会话Cookie。包括设置连接超时、Socket超时、总超时，创建CookieStore与自定义CookieSpec，以及如何将自定义CookieSpec注册到客户端。

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。。
