Windows下安装使用curl命令

本机环境

Windows 7

 

方法/步骤

1、进入网站

https://curl.haxx.se/download/?C=M;O=D网站

2、根据自己的操作系统位数和是否需要SSL下载相应的版本。

这里下载curl-7.33.0-win64-ssl-sspi.zip，下载完成之后解压到需要使用curl命令的目录。这里为了方便我先直接解压到当前目录。

3、在本窗口下打开运行该命令

【没有建立系统环境变量，所以只能在本目录下运行】，检测是否可以正常运行

注意：

         想得到上面的“在此处打开命令窗口(W)”，请使用键盘 Shift+鼠标右键 即可

curl:(60) SSL certificate problem: unable to get  local  issuer certificate
Moredetails here: http: //curl .haxx.se /docs/sslcerts .html

curlperforms SSL certificate verification by default, using a  "bundle"
 of Certificate Authority (CA) public keys (CAcerts). If the default
 bundle  file  isn't adequate, you can specify analternate  file
 using the --cacert option.
Ifthis HTTPS server uses a certificate signed by a CA represented  in
 the bundle, the certificate verificationprobably failed due to a
 problem with the certificate (it might beexpired, or the name might
 not match the domain name  in  the URL).
Ifyou 'd like to turn off curl' s verification of the certificate, use
 the -k (or --insecure) option.

C:\common_command>

4、加入系统环境变量

用户变量和系统变量的区别：

         答： 用户变量：指在该用户登录后该环境变量有效。

              系统变量：指任何用户登录该系统，该环境变量都有效。

           怎么使用：判断该环境变量是否敏感或者是否有用户限制，如果没有则配置在系统变量；否则请根据敏感度或者限制情况配置在用户的环境变量，有利于安全。

 

5、在其他路径下测试是否可以使用CURL命令

成功！

 

 

6、该命令常用作用

答：

1、用于查看该网站可以允许有哪些http请求  【常用：GET, HEAD, POST,PUT, DELETE, OPTIONS】

         我们经常不希望有PUT和DELETE请求，如果有则需要关闭；因为容易造成一些安全问题。
