Curl does not support HTTPS issues

By default, Libcurl does not support HTTPS, and if you use the HTTPS link, the error " Protocol HTTPS not supported or disabled in Libcurl" appears. To see if curl supports HTTPS, you can use the command:

Curl-v.

There are two ways that Curl uses https:

1. Set to No authentication certificate and host

Code = curl_easy_setopt (handle, Curlopt_ssl_verifypeer, 0L);

2. Set up an SSL discriminant certificate

Http://curl.haxx.se/ca/cacert.pem

I don't know how to use these two methods, so I have to use the stupidest way to reload Curl:

1. Download Curl-7.14.0.tar.gz compressed package, many online

2. Unzip: # TAR-ZXVF Curl-7.14.0.tar.gz

# CD curl-7.14.0

#./configure note here that the last message indicates whether HTTPS is supported:

The SSL support prompt here is not supported, because the HTTPS protocol is encrypted security HTTP-based protocol, need to use OpenSSL static library, so need to support https must download OpenSSL, here do not repeat, the method is visible:/http Www.linuxidc.com/Linux/2011-01/31229.htm

# vi/etc/ld.so.conf, in this case join the directory where OpenSSL generated the library file, and use the command Ldconfig to flush the cache.

#./configure--prefix=/usr/local/curl--with-ssl=/usr/local/ssl, note the last piece of information

Tip support for OpenSSL has been supported, then make, and make install.
