如何通過TypeScript和node-fetch庫實(shí)現(xiàn)百度視頻采集
今天給大家分享一個(gè)使用TypeScript和node-fetch庫的采集程序，主要用于采集百度的相關(guān)視頻，代碼非常經(jīng)典，一起來看看吧。
```typescript
import fetch from 'node-fetch';
const getProxy = async (): Promise => {
const response = await fetch('https://www.duoip.cn/get_proxy');
const data = await response.text();
return data.trim();
};
const downloadVideo = async (url: string, proxy: string): Promise => {
const fetchOptions = {
method: 'GET',
headers: {
'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36',
'Proxy-Connection': 'keep-alive',
'Pragma': 'no-cache',
'Cache-Control': 'no-cache',
},
};
if (proxy) {
fetchOptions.agent = new fetch.Agent({
http: {
agent: new fetch.HttpAgent({
host: proxy.split(':')[0],
port: parseInt(proxy.split(':')[1], 10),
protocol: 'http:',
}),
},
});
}
const response = await fetch(url, fetchOptions);
const buffer = await response.buffer();
const videoData = Buffer.from(buffer).toString('base64');
// 保存視頻數(shù)據(jù)到文件
const fs = require('fs');
fs.writeFileSync('output.mp4', Buffer.from(videoData, 'base64'));
};
(async () => {
const proxy = await getProxy();
const videoUrl = 'https://www.baidu.com/xxx/xxx.mp4'; // 請?zhí)鎿Q為目標(biāo)視頻的實(shí)際鏈接
await downloadVideo(videoUrl, proxy);
console.log('視頻下載完成！');
})();
```
上面這段代碼在執(zhí)行過程中，首先獲取代理，然后使用node-fetch將視頻下載到本地。要注意的是，代碼主要用于示例教學(xué)，在實(shí)際使用前，請遵守相關(guān)法律法規(guī)，尊重版權(quán)所有者的權(quán)益。
