java下载抖音视频

下载抖音视频，获取到抖音视频的下载地址之后，类似：

String url = "https://aweme.snssdk.com/aweme/v1/play/?video_id=v0300fbd0000bhkfgq7jofsleq3pk120&line=0&ratio=540p&watermark=1&media_type=4&vr_type=0&test_cdn=None&improve_bitrate=0&logo_name=aweme";

使用URLConnection不能直接下来，使用OkHttp则可以：
添加pom依赖：

<dependency><groupId>com.squareup.okhttp3</groupId><artifactId>okhttp</artifactId><version>3.13.1</version>
</dependency>

	@RequestMapping(value = "/getVideo")public void test(HttpServletResponse res) throws IOException{String url = "https://aweme.snssdk.com/aweme/v1/play/?video_id=v0300fbd0000bhkfgq7jofsleq3pk120&line=0&ratio=540p&watermark=1&media_type=4&vr_type=0&test_cdn=None&improve_bitrate=0&logo_name=aweme";OkHttpClient client = new OkHttpClient();Request request = new Request.Builder().url(url).get().build();Response response = client.newCall(request).execute();//创建接收文件的流//File file = new File( "D:\\" + fileName + ".mp4");//OutputStream outputStream = new FileOutputStream(file);OutputStream outputStream = res.getOutputStream();//将responseBody截取并写入到指定文件路径下outputStream.write(response.body().bytes());outputStream.flush();outputStream.close();}
