Question

我需要从HTTPS网址下载图片。我知道我们可以从远程HTTP URL使用cURL下载图像但是HTTPS协议失败，它返回空白图像。

这样做有什么特别的伎俩吗？网站我必须从amazon.com下载图像

curl可以正常使用HTTPS。从手册页：

   curl  is  a  tool to transfer data from or to a server, using one of the
   supported protocols (DICT, FILE, FTP, FTPS, GOPHER, HTTP,  HTTPS,  IMAP,
   IMAPS,  LDAP,  LDAPS,  POP3,  POP3S, RTMP, RTSP, SCP, SFTP, SMTP, SMTPS,
   TELNET and TFTP).  The command is designed to work without user interac-
   tion.

您可能会遇到证书验证问题。您可以告诉curl忽略这些内容，请参阅-k选项：

   -k, --insecure
          (SSL)  This  option  explicitly allows curl to perform "insecure"
          SSL connections and transfers. All SSL connections are  attempted
          to be made secure by using the CA certificate bundle installed by
          default. This makes all connections  considered  "insecure"  fail
          unless -k, --insecure is used.

          See     this     online    resource    for    further    details:
