怎么确认网址上的文件是下载状态，还是流媒体状态

检查响应头的 Accept-Ranges 是否为 bytes（表示支持按字节范围请求），响应头中 Accept-Ranges: none 表示不支持流媒体。

		
curl -i https://www.netkiller.cn/your-mp3-url.mp3
		
		

请求的响应状态码为 206 Partial Content（部分内容），且包含 Content-Range: bytes 表示支持流媒体

		
curl -H "Range: bytes=0-1023" -i https://www.netkiller.cn/your-mp3-url.mp3
