Android 在post的表单中带上Cookie

在项目中很多情况需要对现有的web网页进行解析和表单提交模拟，最近做毕业设计的时候用到了Android平台提交登陆表单并且要带上Cookie。研究一番后如下：

	/**
	 * 登陆到主页面
	 */
	private void login() {
		HttpPost post = new HttpPost(
				"http://sso.hhit.edu.cn/default.aspx?ReturnUrl=http://sso.hhit.edu.cn:80/Logout.aspx");
		List<NameValuePair> params = new ArrayList<NameValuePair>();
		params.add(new BasicNameValuePair(API.HIDINE1_NAME, API.HIDINE1_VALUE));
		params.add(new BasicNameValuePair(API.HIDINE2_NAME, API.HIDINE2_VALUE));
		params.add(new BasicNameValuePair(API.LOGIN_NAME, mEditTextId.getText()
				.toString().trim()));
		params.add(new BasicNameValuePair(API.LOGIN_PWD, mEditTextPassword
				.getText().toString().trim()));
		params.add(new BasicNameValuePair(API.LOGIN_VCODE, mEditTextValidation
				.getText().toString().trim()));
		params.add(new BasicNameValuePair(API.LOGIN_BUTTON1, ""));
		// 加入cookie
		AppContext.showLog("cookieName:" + mCookieName + "cookieValue:"
				+ mCookieValue);
		Cookie cookie = new BasicClientCookie(mCookieName, mCookieValue);
		post.setHeader("Cookie", "" + mCookieName + "=" + mCookieValue + ";");
		DefaultHttpClient client = new DefaultHttpClient();
		HttpResponse res = null;
		HttpEntity entity = null;
		try {
			post.setEntity(new UrlEncodedFormEntity(params, HTTP.UTF_8));
			res = client.execute(post);
			entity = res.getEntity();
			AppContext.showLog("返回内容" + EntityUtils.toString(entity));
		} catch (Exception e) {
			e.printStackTrace();
		}

		int responseCode = res.getStatusLine().getStatusCode();
		AppContext.showLog("服务器正忙！ 返回代码为：" + responseCode);
		if (responseCode != 200)
			AppContext.showLog("服务器正忙！ 返回代码为：" + responseCode);
		// 得到cookie
		List<Cookie> cookiess = client.getCookieStore().getCookies();
		for (Cookie cookie2 : cookiess) {
			AppContext.showLog("返cookie为：" + cookie2.getName() + "--"
					+ cookie2.getValue());
		}
	}

要带上Cookie很简单，就如http://stackoverflow.com/questions/12280350/sending-cookie-with-http-post-android

中一个回答一样

to add cokie use it like this: it should be added in header

 post.addHeader("Cookie", " PHPSESSID="+PHPSESSID+"; gc_userid="+gc_user+"; gc_session="+gc);

for you it should be like:

 httpost.addHeader("Cookie","session_id = 1234;"...)
