How to update RCurl and curl to the version on the host machine?

问题 Initially I was trying to use devtools::install_github("EdwinTh/padr") where I got the following error: Error in curl::new_handle() : An unknown option was passed in to libcurl After some time I found out that devtools uses curl/RCurl which wraps the current version of curl on the host machine. The host(Ubuntu 14.04.5 LTS) machine version of curl is: 1$ curl -V curl 7.61.0 (x86_64-pc-linux-gnu) libcurl/7.61.0 OpenSSL/1.0.1f zlib/1.2.8 libssh2/1.8.0 librtmp/2.3 where curl is located in: 12$

问题 Is there a way to tell curl command not to use server's side cache? e.g; I have this curl command: curl -v www.example.com how can I ask curl to send a fresh request to not use the cache? Note : I am looking for an executable command in the terminal. 回答1: I know this is an older question, but I wanted to post an answer for users with the same question: curl -H 'Cache-Control: no-cache' http://www.example.com This curl command servers in its header request to return non-cached data from the

TCP/IP TCP/IP是个协议组,可分为三个层次:网络层、传输层和应用层。 在网络层有IP协议、ICMP协议、ARP协议、RARP协议和BOOTP协议。 在传输层中有TCP协议与UDP协议。 在应用层有: TCP包括FTP、HTTP、TELNET、SMTP等协议 UDP包括DNS、TFTP等协议 短连接 连接->传输数据->关闭连接 HTTP是无状态的,浏览器和服务器每进行一次HTTP操作,就建立一次连接,但任务结束就中断连接。 也可以这样说:短连接是指SOCKET连接后发送后接收完数据后马上断开连接。 长连接 连接->传输数据->保持连接 -> 传输数据-> 。。。 ->关闭连接。 长连接指建立SOCKET连接后不管是否使用都保持连接,但安全性较差。 http的长连接 HTTP也可以建立长连接的,使用Connection:keep-alive,HTTP 1.1默认进行持久连接。HTTP1.1和HTTP1.0相比较而言,最大的区别就是增加了持久连接支持(貌似最新的 http1.0 可以显示的指定 keep-alive),但还是无状态的,或者说是不可以信任的。 什么时候用长连接,短连接? 长连接多用于操作频繁,点对点的通讯,而且连接数不能太多情况,。每个TCP连接都需要三步握手,这需要时间,如果每个操作都是先连接,再操作的话那么处理速度会降低很多,所以每个操作完后都不断开

概述 可以这么理解curl命令,curl帮忙构建http请求和接受http响应,所以需要了解http报文格式,以及每个结构使用什么参数进行指定 http报文 请求报文 请求行 方法 -X 指定方法,可选择GET、POST、HEAD、PUT -I 发起HEAD请求,并打印报文头 url 作为curl url的参数 -G 指定查询字符串 -G -d 'key=value&key=value...' 合并格式 -G -d 'key=value' -d 'key=value' 拆分格式 --data--urlencode 用于url编码 版本 报文头 -H 指定报文头 -H 'Content-Type: text/plain' 指定类型 Content-Type: text/xml xml格式 Content-Type: text/plain文本 Content-Type: application/json json格式 application/x-www-form-urlencoded 默认格式 特殊报文头 -e 指定Referer 表示请求来源 -A User-Agent 默认为curl/[version] -b 指定cookie报文头 -b 'foo1=bar1;foo2=bar2' -b cookies.txt 读取本地文件 ps:可以和后续的-c cookies.txt配合使用
