下载微信网页内视频

应朋友要求, 需要下载一些微信购买的课程视频资料, 话不多说, 开干.

1. 获取微信访问头

*首先在浏览器设置微信访问头, 并使用账号密码进行登陆*

• chrome - 更多工具 - 开发者工具 - 右上角 - more tools - Network Conditions - 选择手机访问头
• 输入网址并登录账号密码 - 获取访问头

2. 设置微信访问头

public Document getDoc(String url) throws Exception {
		HttpClient httpClient = HttpClients.createDefault();
		HttpGet httpGet = new HttpGet(url);
		httpGet.setHeader("User-Agent", "MMozilla/5.0 (iPhone; CPU iPhone OS 8_0 like Mac OS X) AppleWebKit/600.1.4 (KHTML, like Gecko) Mobile/12A365 MicroMessenger/5.4.1 NetType/WIFI");
		httpGet.setHeader("Referer","链接");
		httpGet.setHeader("Host", "host 链接");
		httpGet.setHeader("Cookie", " 账号密码cookie ");
		httpGet.setHeader("Accept-Encoding", "gzip, deflate");
		httpGet.setHeader("Accept", "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9");
		HttpResponse response = httpClient.execute(httpGet);
		String contents = EntityUtils.toString(response.getEntity(), "utf-8");// utf-8
		Document document = Jsoup.parse(contents);
		return document;
	}

3. 获取视频页网址

private List<String> getUrls(Document doc) {
		// TODO Auto-generated method stub
		List<String> list = new ArrayList<String>();
		Elements elements = doc.select("body > div.wapbody > div.tbox").select("a");
		for (Element element : elements) {
			String url = "链接头" + element.attr("href");
			System.out.println(url);
			list.add(url);
		}
		return list;
	}

4. 获取bat 脚本下载连接 ( 给电脑盲的傻瓜操作 )

String getVideo(String url) throws Exception {

		Document doc = getDoc(url);
		String docString = doc.toString();
		String name = doc.select("body > div.wapbody > div.tbox > div.teaching-title > h1").text();
		int fromIndex = docString.indexOf("http://");
		int toIndex = docString.indexOf(".mp4");
		String nameString = name.replaceAll("）", "").replaceAll("（", "").replaceAll("：", "");
		String urlString = docString.substring(fromIndex, toIndex+4);
		return "curl -# -o "+nameString+" "+urlString;
		
	}

5. 打印脚本下载连接并另存为bat脚本, 就OK了

总结:

感觉对于 Jsoup 的 selector 还不太熟悉, 需要再好好看一下.
