Node.js解析无水印原视频链接：提取视频源代码示例

"Node.js解析无水印原视频链接：提取视频源代码示例"\n\n本教程演示如何使用Node.js和axios、cheerio库从网页中解析无水印原视频链接。示例代码展示了提取视频源代码的步骤，并提供详细解释。\n\njavascript\nconst axios = require('axios');\nconst cheerio = require('cheerio');\n\nasync function parseVideoUrl(videoUrl) {\n try {\n const response = await axios.get(videoUrl);\n const html = response.data;\n const $ = cheerio.load(html);\n \n // 解析视频链接\n const videoElement = $('video');\n const videoUrl = videoElement.find('source').attr('src');\n \n return videoUrl;\n } catch (error) {\n console.error('Error parsing video URL:', error);\n return null;\n }\n}\n\n// 示例用法\nconst videoUrl = 'https://example.com/video'; // 替换为实际的无水印原视频链接\nparseVideoUrl(videoUrl)\n .then((videoUrl) => {\n if (videoUrl) {\n console.log('Video URL:', videoUrl);\n } else {\n console.log('Failed to parse video URL');\n }\n })\n .catch((error) => {\n console.error('Error parsing video URL:', error);\n });\n\n\n请注意，此代码使用了axios和cheerio库来进行HTTP请求和HTML解析。您需要先安装这两个依赖项，通过运行以下命令：\n\n\nnpm install axios cheerio\n\n\n请将示例代码中的https://example.com/video替换为实际的无水印原视频链接。
