HTTP请求使用CMWAP接入点的设置和会话保持

• 使用CMWAP接入点进行HTTP请求

需要在请求参数中加入代理，地址为10.0.0.172，端口为80

HttpParams baseParams = new BasicHttpParams();
baseParams.setParameter(ConnRoutePNames.DEFAULT_PROXY, new HttpHost("10.0.0.172", 80));
DefaultHttpClient httpclient = new DefaultHttpClient(baseParams);
HttpGet httpget = new HttpGet(url);

• HTTP请求中的会话保持

通过保存和设置HTTP请求的cookie来实现，大多网站只要保存和设置sessionid（cookie中名字为JSESSIONIDWAP）即可，但有的网站还有一些其他的参数，所以可以用一个HASHMAP来存储。

HashMap cookieMap = new HashMap()用来存储每次请求后返回的COOKIE值，存储方法随意，静态变量、数据库都可以。

 

		StringBuffer cookieString = new StringBuffer();
　　　　　　　　　 Iterator iterator = cookieMap.entrySet().iterator();
		while (iterator.hasNext()) {
			Entry entry = (Entry) iterator.next();
			Object value = entry.getValue();
			Object key = entry.getKey();
			cookieString.append(key).append("=").append(value);
			if (iterator.hasNext()) {
				cookieString.append(";");
			}
		}
		httpget.setHeader("cookie", cookieString.toString());//设置cookie值
		ResponseHandler responseHandler = new BasicResponseHandler();
		String responseBody = httpclient.execute(httpget, responseHandler);　
		List cookies = httpclient.getCookieStore().getCookies();//获取、保存cookie
		if (cookies.isEmpty()) {
			Log.i(ConfigUtil.LOGTAG, "cookies = none");
		} else {
			cookieMap.clear();
			for (int i = 0; i < cookies.size(); i++) {
				Cookie cookie = (Cookie) cookies.get(i);
				Log.i(ConfigUtil.LOGTAG, ((Cookie) cookies.get(i)).getName() + "::::" + ((Cookie) cookies.get(i)).getValue());
				cookieMap.put(cookie.getName(), cookie.getValue());
			}
		}
