当我尝试从互联网上下载文件时，我发现同样的链接下载失败了https但是成功用http。
e.g。
wget https://devimages.apple.com.edgekey.net/streaming/examples/bipbop_4x3/gear4/fileSequence0.ts
--2014-01-31 16:01:05-- https://devimages.apple.com.edgekey.net/streaming/examples/bipbop_4x3/gear4/fileSequence0.ts

但如果我将https更改为http，它可以正常工作：
wget https://devimages.apple.com.edgekey.net/streaming/examples/bipbop_4x3/gear4/fileSequence0.ts

https下载失败的原因是什么？
答案 0 :(得分：3)
使用wget --no-check-certificate参数。

我认为因为https是ssl的协议，所以它应该在服务器上受支持，如果支持，你需要使用握手协议，警报协议，密码和记录协商参数。
