无论我为curl指定了什么URL,我都会得到相同的
HTML 404错误页面.
如果我使用–verbose选项,看起来curl总是连接到同一个IP地址.

curl –version的输出是:
curl 7.15.5 (x86_64-redhat-linux-gnu) libcurl/7.15.5 OpenSSL/0.9.8b zlib/1.2.3 libidn/0.6.5 Protocols: tftp ftp telnet dict ldap http file https ftps Features: GSS-Negotiate IDN IPv6 Largefile NTLM SSL libz
如果我改用wget,那么我会找回正确的页面.
任何想法如何获得curl正确解析URL?
谢谢.
解决方法
* Connected to www.edgeoftheweb.co.uk (::ffff:74.117.222.24) port 80 * Connected to api.twitter.com (::ffff:74.117.222.24) port 80
在wget使用ipv4时,我似乎正在使用ipv6进行连接
请尝试以下方法
curl --verbose -4 http://api.twitter.com
