 		//设置支持AJAX
        webClient.setAjaxController(new NicelyResynchronizingAjaxController());
        ////开启页面重定向
        webClient.getOptions().setRedirectEnabled(true);
		//关闭ssl安全访问
        webClient.getOptions().setUseInsecureSSL(false);
		//关闭异常抛出
        webClient.getOptions().setThrowExceptionOnFailingStatusCode(false);
        webClient.getOptions().setThrowExceptionOnScriptError(false);
        //忽略解析 css js false
        webClient.getOptions().setCssEnabled(false);
        webClient.getOptions().setJavaScriptEnabled(false);
//设置是否允许本机 ActiveX。默认值为假。请注意，除非您完全信任 JavaScript 代码，否则绝不应该允许运行本机 ActiveX 组件，因为它不受 Java 虚拟机控制
        webClient.getOptions().setActiveXNative(false);
  1. 获取HtmlPage信息
1
2
//String baseUrl = "https://v.douyin.com/j472ue4/";  
page = webClient.getPage(baseUrl);

4.获取跳转url

1
2
 String  realUrl=page.getUrl().toString();
//https://www.douyin.com/video/7111515518200237343?previous_page=app_code_link

5.截取 video/后面开头到？之间的Id ,然后拼接API 请求接口 返回JSON数据

String getJson=API+realUrl.substring(s.lastIndexOf("/") + 1, s.indexOf("?"));

String s2 = HttpUtil.get(getJson);

JSON 数据如下：

6.转换成JSON对象

//取名item_list列表第一组数据
  JSONObject jsonObject = JSONUtil.parseObj(s2);
       JSONObject item = jsonObject
                .getJSONArray("item_list")
                .getJSONObject(0);
                
 //再取其下video数据
  JSONObject video = jsonObject.getJSONObject("video");
  //取出键名play_addr下的url_list列表第一组数据
 String videoUrl= video.getJSONObject("play_addr").getJSONArray("url_list").getStr(0);
 //"https://aweme.snssdk.com/aweme/v1/playwm/?video_id=v0200fg10000caoiq33c77uesglpt9gg&ratio=720p&line=0"

注意：

此链接的playwm中的wm需要去掉，才是无水印视频，否则依旧留有水印

String finalUrl=videoUrl.replace(“playwm”, “play”);

7.根据链接地址下载到本地

1
HttpUtil.downloadFile(finalUrl, new File("D:\\123.mp4"));
