Android HttpClient使用Cookie应用分析

public class MainActivity extends Activity {

private AndroidHttpClient mHttpclient=AndroidHttpClient.newInstance("");

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

findViewById(R.id.button1).setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

// TODO Auto-generated method stub

new Thread(rTest).start();

}

});

}

private String toString(InputStream is) throws IOException{

String ret="";

InputStreamReader isr=new InputStreamReader(is);

BufferedReader br=new BufferedReader(isr);

String tmp=br.readLine();

while(tmp!=null){

ret+=tmp;

tmp=br.readLine();

}

br.close();

return ret;

}

private Runnable rTest=new Runnable() {

@Override

public void run() {

// TODO Auto-generated method stub

try {

BasicHttpContext context=new BasicHttpContext();

context.setAttribute(ClientContext.COOKIE_STORE,new BasicCookieStore());

HttpPost httppost = new HttpPost("http://10.226.233.48:8080/WebApplication1/LogIn");

List <NameValuePair> nvps = new ArrayList <NameValuePair>();

nvps.add(new BasicNameValuePair("info", "你好 世界！！"));

httppost.setEntity(new UrlEncodedFormEntity(nvps,"utf-8"));

HttpResponse response=mHttpclient.execute(httppost,context);

HttpEntity entity = response.getEntity();

Log.i("kagami", MainActivity.this.toString(entity.getContent()));

entity.consumeContent();

HttpGet httpget2 = new HttpGet("http://10.226.233.48:8080/WebApplication1/Info");

HttpResponse response2=mHttpclient.execute(httpget2,context);

HttpEntity entity2 = response2.getEntity();

Log.i("kagami", MainActivity.this.toString(entity2.getContent()));

entity2.consumeContent();

}catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

};

｝

AndroidHttpClient和DefaultHttpClient的区别：

AndroidHttpClient不能在主线程中execute，会抛出异常。AndroidHttpClient通过静态方法newInstance获得实例，参数是代理，不用代理的话填“”。DefaultHttpClient默认是启用Cookie的，AndroidHttpClient默认不启用Cookie，要使用的话每次execute时要加一个HttpContext参数，并且添加CookieStore。用完后别忘了close不然不能创建新实例。

详细出处参考：http://www.jb51.net/article/32196.htm

httpclient与webview需要进行cookie 共享，因为如果不共享，那么假设你在httpclient进行了登录，然后用webview里打开那些login之后才能看的page，就会叫你再login

[java]
view plaincopyprint?

DefaultHttpClient httpclient=....;
String toUrl="https://cap.cityu.edu.hk/studentlan/details.aspx.....";

List<Cookie> cookies = httpclient.getCookieStore().getCookies();

if (! cookies.isEmpty()){
CookieSyncManager.createInstance(this);
CookieManager cookieManager = CookieManager.getInstance();
//sync all the cookies in the httpclient with the webview by generating cookie string

for (Cookie cookie : cookies){
String cookieString = cookie.getName() + "=" + cookie.getValue() + "; domain=" + cookie.getDomain();
cookieManager.setCookie(toUrl, cookieString);
CookieSyncManager.getInstance().sync();
}

面的 post 可以 成功 登陆。账号 （a1008611）密码（a1008611）

但我要登陆 后 http://bbs.newgxu.cn/user/upgrade.yws 的信息。却被重 定向到 登陆 界面了（http://bbs.newgxu.cn/login.yws）？

在这也可以 登陆！！
http://bbs.newgxu.cn/index.yws
要登录 才能 看见 的网页（http://bbs.newgxu.cn/user/upgrade.yws）否则 会被 重定向 想到 登陆 界面。

我用的是 android 4.1 jar包。是不是 这里的apache 的jar 包 cookie 不会自动 保存 啊？

求教 ，谢谢！！

responsepost = client.execute(post, httpcontext);

post方式执行后应该记录下cookie，get方式执行前也应该像post那样添加cookie到Header信息里。

但 httpclient 不是自动处理 cookie 吗？如果 自己 写 应该 如何 记录cookie？

view source

print?

01	List<Cookie> cookies = client.getCookieStore().getCookies();

02	if (!cookies.isEmpty()) {

03	for (Cookie cookie : cookies) {

04	String cookie_domain = cookie.getDomain();

05	String cookie_name = cookie.getName());

06	String cookie_value = cookie.getValue());

07	String cookie_version = cookie.getVersion();

08	String cookie_path = cookie.getPath();

09

}

得到cookie的多个属性，如何使用,让两级网页使用同一cookie便别身份。本人有点菜。麻烦了！谢谢了。

这个需要你自己在后台做好生成和验证cookie的处理，比如生成cookie的时候带上userID，验证cookie的时候跟据你自己定
