今天头条网站的模拟登陆及新闻的评论

近来今日头条特别的火，就拿来研究研究！

头条的新闻内容和新闻评论是开放的，无需登陆就可以获取的到！

但是新闻的评论是需要登陆后才能进行评论的，于是开始模拟头条的用户登陆：

1.模拟登陆的操作能够获取到cookie值，定位initCookie,但是该cookie值不能直接用来作为对新闻进行评论的请求参数。

2.需要找到一个新闻url，例如：http://toutiao.com/a4583986550/，将上部获取的cookie值作为参数，模拟请求，获取到cookie,定为lastCookie.

3.将initCookie和lastCookie进行拼接就可获取到最终的可用于新闻评论的cookie

代码如下：

	private String doLoginTouTiao2(String loginName, String password) {
		String url = "https://mp.toutiao.com/auth/login_post/";
		Map<String, String> headers = new HashMap<String, String>();
		Map<String, String> params = new HashMap<String, String>();
		headers.put("Host", "mp.toutiao.com");
		headers.put("Connection", "keep-alive");
		headers.put("Origin", "https://mp.toutiao.com");
		headers.put(
				"User-Agent",
				"Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2272.118 Safari/537.36");
		headers.put("Content-Type",
				"application/x-www-form-urlencoded; charset=UTF-8");
		headers.put("Accept", "application/json, text/javascript, */*; q=0.01");
		headers.put("X-Requested-With", "XMLHttpRequest");
		headers.put("X-CSRFToken", "b3ebed559047fa1cacaccc6ccfb66851");
		headers.put("Referer", "https://mp.toutiao.com/login/");
//		headers.put("Accept-Encoding", "gzip, deflate");
		headers.put("Accept-Language", "zh-CN,zh;q=0.8");
//		String cookie = "uuid=\"w:0256c3403d82490abcc2c7819d48865f\"; tt_webid=3932107506; utm_source=toutiao; __utma=24953151.381297160.1435021810.1435023762.1435106245.3; __utmc=24953151; __utmz=24953151.1435106245.3.2.utmcsr=baidu|utmccn=(organic)|utmcmd=organic|utmctr=%E4%BB%8A%E6%97%A5%E5%A4%B4%E6%9D%A1; _gat=1; sessionid=249d2efbe15e67a4ff000a9ffe489c4e; csrftoken=b3ebed559047fa1cacaccc6ccfb66851; _ga=GA1.2.381297160.1435021810";
//		headers.put("Cookie", cookie);

		params.put("name_or_email", loginName);
		params.put("password", password);

		HttpResponse response = HttpUtils.doPost(url, headers, params);

		List<Cookie> cookies = HttpUtils.getResponseCookies(response);
		String cookieStr = HttpUtils.setCookie2String(cookies);
		System.out.println("cookieStr:" + cookieStr);

		String responseText = HttpUtils.getStringFromResponse2(response,
				"utf-8");
		System.out.println(responseText);

		return HttpUtils.setCookie2String(cookies);
	}

获取lastCookie值：

	public void publicNewsComment(String cookieStr,String csrfToken) {
		
		String url="http://toutiao.com/group/4560598775/post_comment/";
		Map<String,String> headers=new HashMap<String,String>();
		Map<String, String> params = new HashMap<String, String>();
		headers.put("Accept", "application/json, text/javascript, */*; q=0.01");
		headers.put("Accept-Language", "zh-CN,zh;q=0.8");
		headers.put("Connection", "keep-alive");
		headers.put("Content-Type", "application/x-www-form-urlencoded; charset=UTF-8");
		headers.put("Host", "toutiao.com");
		headers.put("Origin", "http://toutiao.com");
		headers.put("Referer", "http://toutiao.com/a4560598775/");
		headers.put("User-Agent", "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2272.118 Safari/537.36");
		headers.put("X-CSRFToken", csrfToken);
		headers.put("X-Requested-With", "XMLHttpRequest");
//		cookieStr="uuid=\"w:0256c3403d82490abcc2c7819d48865f\"; tt_webid=3932107506; sessionid=249d2efbe15e67a4ff000a9ffe489c4e; _ga=GA1.2.381297160.1435021810; __utmt=1; utm_source=toutiao; csrftoken=382a7061c9b0b4abe3c4558ad3847df4; __utma=24953151.381297160.1435021810.1435117044.1435124287.5; __utmb=24953151.6.8.1435124301975; __utmc=24953151; __utmz=24953151.1435124287.5.3.utmcsr=baidu|utmccn=(organic)|utmcmd=organic|utmctr=%E4%BB%8A%E6%97%A5%E5%A4%B4%E6%9D%A1";
//		cookieStr="uuid=\"w:0256c3403d82490abcc2c7819d48865f\"; tt_webid=3932107506; sessionid=249d2efbe15e67a4ff000a9ffe489c4e; _ga=GA1.2.381297160.1435021810; __utmt=1; utm_source=toutiao; csrftoken=382a7061c9b0b4abe3c4558ad3847df4; __utma=24953151.381297160.1435021810.1435117044.1435124287.5; __utmb=24953151.6.8.1435124301975; __utmc=24953151; __utmz=24953151.1435124287.5.3.utmcsr=baidu|utmccn=(organic)|utmcmd=organic|utmctr=%E4%BB%8A%E6%97%A5%E5%A4%B4%E6%9D%A1";
//		cookieStr=cookieStr+"csrftoken=382a7061c9b0b4abe3c4558ad3847df4;";
		headers.put("Cookie", cookieStr);
		
		params.put("status", "啊啊啊啊啊!你这么做让释永信大僧脸面何在啊!");
		
		HttpResponse response = HttpUtils.doPost(url, headers, params);
		System.out.println(response);
		
		String responseText =HttpUtils.getStringFromResponse2(response,"utf-8");
		System.out.println(responseText);
	}

 运行main方法：

	public static void main(String[] args) {
		LoginTouTiao loginTT = new LoginTouTiao();
		String cookieStr = loginTT.doLoginTouTiao2("763197812@qq.com",
				"123456");
		System.out.println(cookieStr);
		String csrfToken=loginTT.fetchCsrfToken2(cookieStr);
		cookieStr=cookieStr+";"+csrfToken;
		
		String[] ss=csrfToken.split(";");
		String s=ss[0];
		String[] tokens=s.split("=");
		String token=tokens[1];
		System.out.println(token);
		
		 SpiderTouTiao2 spider=new SpiderTouTiao2();
		 spider.publicNewsComment(cookieStr,token);
	}
