在我的程序（使用OpenSSL）和curl中，我无法获取网站：
$ curl -v https://registration.experient-inc.com/HTMLProduction/ShowCES131/ConfirmationImages/CES131_Header.JPG * About to connect() to registration.experient-inc.com port 443 (#0) * Trying 12.153.51.94... * connected * Connected to registration.experient-inc.com (12.153.51.94) port 443 (#0) * successfully set certificate verify locations: * CAfile: /usr/ssl/certs/ca-bundle.crt CApath: none * SSLv3, TLS handshake, Client hello (1): * Unknown SSL protocol error in connection to registration.experient-inc.com:443 * Closing connection #0 curl: (35) Unknown SSL protocol error in connection to registration.experient-inc.com:443
根据一个不同的问题，我将发布直接openssl调用发生的事情：
$ openssl s_client -host 12.153.51.94 -port 443 CONNECTED(00000003) write:errno=104 --- no peer certificate available --- No client certificate CA names sent --- SSL handshake has read 0 bytes and written 320 bytes --- New, (NONE), Cipher is (NONE) Secure Renegotiation IS NOT supported Compression: NONE Expansion: NONE ---
知道为什么会发生这种情况/如何解决它？
答案 0 :(得分：1)
显然，Web服务器根本不支持SSLv2。即它甚至不支持SSLv2你好。强制curl或OpenSSL使用SSLv3 +会导致工作查询。
