linuxea:curl常用命令 curl常用命令time_connect : 建立到服务器的 TCP 连接所用的时间time_starttransfer: 在发出请求之后，Web 服务器返回数据的第一个字节所用的时间time_total: 完成请求所用的时间在 发出请求之后，Web 服务器处理请求并开始发回数据所用的时间是（time_starttransfer）1.044 - （time_connect）0.244 = 0.8 秒客户机从服务器下载数据所用的时间是（time_total）2.672 - （time_starttransfer）1.044 = 1.682 秒指定特定主机IP地址访问网站 curl -x 61.1315.169.105:80 http://www.baidu.com curl -x 61.1315.169.125:80 http://www.baidu.com网页响应时间curl -o /dev/null -s -w "time_connect: %{time_connect}\ntime_starttransfer: %{time_starttransfer}\ntime_total: %{time_total}\n" "http://www.linuxea.com" time_connect: 0.009 time_starttransfer: 0.357 time_total: 0.358状态返回码curl -s -w %{http_code} "http://www.baidu.com"完成请求所用的时间curl -o /dev/null -s -w '%{time_total}' http://www.linuxea.com 0.456或者如下curl -o /dev/null -s -w "%{http_code}\n%{time_connect}\n%{time_starttransfer}\n%{time_total}" http://www.baidu.com 200 0.038 0.071 0.071文件创建一个新文件 curl-format.txt，然后粘贴： time_namelookup: %{time_namelookup}s\n time_connect: %{time_connect}s\n time_appconnect: %{time_appconnect}s\n time_pretransfer: %{time_pretransfer}s\n time_redirect: %{time_redirect}s\n time_starttransfer: %{time_starttransfer}s\n ----------\n time_total: %{time_total}s\n发出请求：curl -w "@curl-format.txt" -o /dev/null -s "http://wordpress.com/"或者在 Windows 上，它是... curl -w "@curl-format.txt" -o NUL -s "http://wordpress.com/"这是做什么的：-w "@curl-format.txt"告诉 cURL 使用我们的格式文件-o /dev/null将请求的输出重定向到 /dev/null-s 告诉 cURL 不要显示进度表"http://wordpress.com/"是我们请求的 URL。如果您的 URL 具有“&”查询字符串参数，请特别使用引号输出 time_namelookup: 0.001s time_connect: 0.037s time_appconnect: 0.000s time_pretransfer: 0.037s time_redirect: 0.000s time_starttransfer: 0.092s ---------- time_total: 0.164s制作 Linux/Mac 快捷方式（别名）alias curltime="curl -w \"@$HOME/.curl-format.txt\" -o /dev/null -s "然后你可以简单地调用...curltime wordpress.org

linuxea:centos7.9使用trojan加速拉取代码 我们经常使用github或者其他的仓库，特别慢的时候，可以使用其他的浏览器插件来解决。但是，假设你已经购买了trojan，并且想在linux上使用，就可以考虑如下办法首先，在trojan下载一个版本即可，而后参考trojan的方式将配置文件导入到config.json中现在你有一个已经在页面生成好的配置文件，而后修改验证修改verify和verify_hostname为false，这在trojan的github上并没有得到解决，于是我们就不验证即可 "ssl": { "verify": false, "verify_hostname": false, "cert": "",直接运行起来~/trojan-1.15]# ./trojan -c config.json Welcome to trojan 1.15.1 [2022-04-02 11:38:01] [WARN] trojan service (client) started at 127.0.0.1:1080而后配置一个privoxyyum install privoxy -y添加配置文件listen-address 127.0.0.1:1081 toggle 0 show-on-task-bar 0 activity-animation 0 forward-socks5 / 127.0.0.1:1080 . hide-console并启动systemctl start privoxy.serviceexport http_proxy=http://localhost:1081/ export https_proxy=http://localhost:1081/打开一下谷歌# curl -o /dev/null -s -w "%{http_code}" www.google.com && echo 200返回追踪下日志# ./trojan -c config.json Welcome to trojan 1.15.1 [2022-04-02 11:38:01] [WARN] trojan service (client) started at 127.0.0.1:1080 [2022-04-02 11:39:21] [INFO] 127.0.0.1:42136 requested connection to www.google.com:80 [2022-04-02 11:39:22] [INFO] 127.0.0.1:42136 disconnected, 14790 bytes received, 78 bytes sent, lasted for 1 seconds [2022-04-02 11:39:37] [INFO] 127.0.0.1:42302 requested connection to www.google.com:80 [2022-04-02 11:39:57] [ERROR] 127.0.0.1:42302 cannot resolve remote server hostname de1-1.nigirocloud.com: Host not found (authoritative) [2022-04-02 11:39:57] [INFO] 127.0.0.1:42302 disconnected, 0 bytes received, 78 bytes sent, lasted for 20 seconds [2022-04-02 11:40:54] [INFO] 127.0.0.1:43156 requested connection to www.google.com:80 [2022-04-02 11:41:04] [ERROR] 127.0.0.1:43156 cannot resolve remote server hostname de1-1.nigirocloud.com: Host not found (authoritative) [2022-04-02 11:41:04] [INFO] 127.0.0.1:43156 disconnected, 0 bytes received, 78 bytes sent, lasted for 10 seconds [2022-04-02 11:41:14] [INFO] 127.0.0.1:43380 requested connection to www.google.com:80 [2022-04-02 11:41:15] [INFO] 127.0.0.1:43380 disconnected, 14783 bytes received, 78 bytes sent, lasted for 1 seconds [2022-04-02 11:41:32] [INFO] 127.0.0.1:43596 requested connection to www.google.com:80 [2022-04-02 11:41:33] [INFO] 127.0.0.1:43596 disconnected, 14806 bytes received, 78 bytes sent, lasted for 1 seconds [2022-04-02 11:41:35] [INFO] 127.0.0.1:43626 requested connection to www.google.com:80 [2022-04-02 11:41:41] [INFO] 127.0.0.1:43626 disconnected, 14805 bytes received, 78 bytes sent, lasted for 6 seconds [2022-04-02 11:41:44] [INFO] 127.0.0.1:43734 requested connection to www.google.com:80 [2022-04-02 11:41:45] [INFO] 127.0.0.1:43734 disconnected, 14823 bytes received, 78 bytes sent, lasted for 1 seconds [2022-04-02 11:41:51] [INFO] 127.0.0.1:43830 requested connection to www.google.com:80 [2022-04-02 11:41:52] [INFO] 127.0.0.1:43830 disconnected, 14759 bytes received, 78 bytes sent, lasted for 1 seconds现在就可以发起http的请求
