用curl访问HTTPS站点并登录
开发网站,少不了测试。现在的网站为了加强安全性,都启用了HTTPS协议。所谓HTTPS,也就是HTTP文本在SSL协议中传输。用curl命令行来测试HTTPS站点是个很有用的功能,写点脚本,就可以做功能测试。
假定Ubuntu系统运行着一个HTTPS站点,用CppCMS编写,Nginx配置了SSL证书,通过FastCGI和CppCMS编写的后台进程连接在一起。
第一步,安装:
apt-get install curl
我的Ubuntu是13.04, 因此安装的curl版本很新,下面的命令检查版本号和其他信息:
curl -V curl 7.29.0 (x86_64-pc-linux-gnu) libcurl/7.29.0 OpenSSL/1.0.1c zlib/1.2.7 libidn/1.25 librtmp/2.3 Protocols: dict file ftp ftps gopher http https imap imaps ldap ldaps pop3 pop3s rtmp rtsp smtp smtps telnet tftp Features: GSS-Negotiate IDN IPv6 Largefile NTLM NTLM_WB SSL libz TLS-SRP
我们可以看到启用了SSL, 并且openssl版本是1.0.1c。
第二步,访问HTTP站点:
curl http://www.baidu.com <!DOCTYPE html><!--STATUS OK--><html><head><meta http-equiv="content-type" content="text/html;charset=utf-8"><title>百度一下,你就知道<unction(){var _t=new Date().getTime();document.cookie = "WWW_ST=" + _t +";expires=" + new Date(_t + 10000).toGMTString()})}catch(e){}</script></html><!--b5d54ba904675fbf-->
返回了百度的网页内容。内容太多,裁剪了。
第三步,查看详细信息,用-v参数。
curl -v http://www.baidu.com * About to connect() to www.baidu.com port 80 (#0) * Trying 61.135.169.125... * Connected to www.baidu.com (61.135.169.125) port 80 (#0) > GET / HTTP/1.1 > User-Agent: curl/7.29.0 > Host: www.baidu.com > Accept: */* > < HTTP/1.1 200 OK < Date: Wed, 03 Jul 2013 13:55:45 GMT < Server: BWS/1.0 < Content-Length: 10437 < Content-Type: text/html;charset=utf-8 < Cache-Control: private < Set-Cookie: BDSVRTM=24; path=/ < Set-Cookie: H_PS_PSSID=2757_1457_2704_2726_1788_2249_2702; path=/; domain=.baidu.com < Set-Cookie: BAIDUID=5E81F8E70C5DE6EDB5C24088E3E56359:FG=1; expires=Wed, 03-Jul-43 13:55:45 GMT; path=/; domain=.baidu.com < Expires: Wed, 03 Jul 2013 13:55:45 GMT < P3P: CP=" OTI DSP COR IVA OUR IND COM " < Connection: Keep-Alive < <!DOCTYPE html><!--STATUS OK--><html><head><meta http-equiv="content-type" content="text/html;charset=utf-8"><title>百度一下,你就知道</title><style >html,body{height:100%}html{overflow-y:auto}#wrapper{position:relative;_position:;min-height:100%}#content{padding-bottom:100px;text-align:center}#ftCon{height:100px;position:absolute;bottom:44px;text-align:center;width:100%;margin:0 auto;z-index:0;overflow:hidden}#ftConw{width:720px;margin:0 auto}body{font:12px arial;text-align:;background:#fff}body,p,form,ul,li{margin:0;padding:0;list-style:none}body,form,#fm{position:relative}td{text-align:left}img{border:0}a{color:#00c}a:active{color:#f60}#u{color:#999;padding:4px 10px 5px 0;text-align:right}#u a{margin:0 5px}#u .reg{margin:0}#m{width:720px;margin:0 auto}#nv a,#nv b,.btn,#lk{font-size:14px}#fm{padding-left:110px;text-align:left;z-index:1}input{border:0;padding:0}#nv{height:19px;font-size:16px;margin:0 0 4px;text-alig
这样详细的信息都显示出来了。-v参数很有用,一般调试时都打开。
如果只想查看头部信息,用-i代替-v.
第四步,访问本地HTTPS站点
curl --insecure https://localhost/your_site/login_page <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="content-type" content="text/html; charset=utf-8"> <meta http-equiv="pragma" content="no-cache"> <meta http-equiv="cache-control" content="no-cache">
---insecure表示忽略校验步骤。
我试过用--cacert选项指定server.crt文件,也就是我的nginx使用的那个文件。但是报错。所以直接忽略算了。
第五步,调用HTTPS的login API登录
curl -v --insecure -d "email=gche@yousite.com&pwd=123456&language=en" https://localhost/your_site/login * About to connect() to localhost port 443 (#0) * Trying 127.0.0.1... * Connected to localhost (127.0.0.1) port 443 (#0) * successfully set certificate verify locations: * CAfile: none CApath: /etc/ssl/certs * SSLv3, TLS handshake, Client hello (1): * SSLv3, TLS handshake, Server hello (2): * SSLv3, TLS handshake, CERT (11): * SSLv3, TLS handshake, Server key exchange (12): * SSLv3, TLS handshake, Server finished (14): * SSLv3, TLS handshake, Client key exchange (16): * SSLv3, TLS change cipher, Client hello (1): * SSLv3, TLS handshake, Finished (20): * SSLv3, TLS change cipher, Client hello (1): * SSLv3, TLS handshake, Finished (20): * SSL connection using ECDHE-RSA-AES256-SHA * Server certificate: * subject: C=AU; ST=Some-State; O=Internet Widgits Pty Ltd * start date: 2013-06-02 07:24:53 GMT * expire date: 2014-06-02 07:24:53 GMT * issuer: C=AU; ST=Some-State; O=Internet Widgits Pty Ltd * SSL certificate verify result: self signed certificate (18), continuing anyway. > POST /your_site/login HTTP/1.1 > User-Agent: curl/7.29.0 > Host: localhost > Accept: */* > Content-Length: 51 > Content-Type: application/x-www-form-urlencoded > * upload completely sent off: 51 out of 51 bytes < HTTP/1.1 200 OK < Server: nginx/1.5.1 < Date: Wed, 03 Jul 2013 14:02:38 GMT < Content-Type: text/html; charset=utf-8 < Transfer-Encoding: chunked < Connection: keep-alive < X-Powered-By: CppCMS/1.0.3 < Set-Cookie: cml_session=518b7fc5117e87bce28f2444; Max-Age=36000; Path=/; Version=1 < * Connection #0 to host localhost left intact {"message":"Login succeeded!","status":0,"value":""}
-d "...&..." 的参数是通过POST方法发送参数。服务端最终回复一个JSON格式的字符串,表示登录成功。并且拿到了cml_session的值,也就是cookie.
第六步,用cookie访问HTTP网页。后面的网页只需要HTTP访问,提供正确的cookie即可。
curl -v --cookie "cml_session=518b7fc5117e87bce28f2444" http://localhost/your_site/home * About to connect() to localhost port 80 (#0) * Trying 127.0.0.1... * Connected to localhost (127.0.0.1) port 80 (#0) > GET /your_site/home HTTP/1.1 > User-Agent: curl/7.29.0 > Host: localhost > Accept: */* > Cookie: cml_session=518b7fc5117e87bce28f2444 > < HTTP/1.1 200 OK < Server: nginx/1.5.1 < Date: Wed, 03 Jul 2013 14:06:43 GMT < Content-Type: text/html; charset=utf-8 < Transfer-Encoding: chunked < Connection: keep-alive < X-Powered-By: CppCMS/1.0.3 < <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="content-type" content="text/html; charset=utf-8"> <meta http-equiv="pragma" content="no-cache"> <meta http-equiv="cache-control" content="no-cache"> <meta http-equiv="expires" content="0"> <title>CML Cloud</title> <link type="text/css" href="../style/reset.css" rel="stylesheet"/> <link type="text/css" href="../style/style.css" rel="stylesheet"/>
