Linux curl命令参数详解

linux curl是通过url语法在命令行下上传或下载文件的工具软件，它支持http,https,ftp,ftps,telnet等多种协议，常被用来抓取网页和监控Web服务器状态。

一、Linux curl用法举例：

1. linux curl抓取网页：

抓取百度：

<textarea class="crayon-plain print-no" data-settings="dblclick" readonly="readonly" style="margin: 0px; padding: 0px 5px; border-width: 0px; width: 598px; overflow: hidden; height: 15px; position: absolute; opacity: 0; box-shadow: none; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; -webkit-box-shadow: none; word-wrap: normal; resize: none; color: rgb(0, 0, 0); tab-size: 4; z-index: 0; line-height: 15px !important;"></textarea>

1	curl http : //www.baidu.com

如发现乱码，可以使用iconv转码：

<textarea class="crayon-plain print-no" data-settings="dblclick" readonly="readonly" style="margin: 0px; padding: 0px 5px; border-width: 0px; width: 598px; overflow: hidden; height: 15px; position: absolute; opacity: 0; box-shadow: none; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; -webkit-box-shadow: none; word-wrap: normal; resize: none; color: rgb(0, 0, 0); tab-size: 4; z-index: 0; line-height: 15px !important;"></textarea>

1	curl http : //iframe.ip138.com/ic.asp|iconv -fgb2312

iconv的用法请参阅：在Linux/Unix系统下用iconv命令处理文本文件中文乱码问题

2. Linux curl使用代理：

linux curl使用http代理抓取页面：

<textarea class="crayon-plain print-no" data-settings="dblclick" readonly="readonly" style="margin: 0px; padding: 0px 5px; border-width: 0px; width: 598px; overflow: hidden; height: 30px; position: absolute; opacity: 0; box-shadow: none; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; -webkit-box-shadow: none; word-wrap: normal; resize: none; color: rgb(0, 0, 0); tab-size: 4; z-index: 0; line-height: 15px !important;"></textarea>

1 2	curl - x 111.95.243.36 : 80 http : //iframe.ip138.com/ic.asp|iconv -fgb2312 curl - x 111.95.243.36 : 80 - U aiezu : password http : //www.baidu.com

使用socks代理抓取页面：

<textarea class="crayon-plain print-no" data-settings="dblclick" readonly="readonly" style="margin: 0px; padding: 0px 5px; border-width: 0px; width: 598px; overflow: hidden; height: 30px; position: absolute; opacity: 0; box-shadow: none; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; -webkit-box-shadow: none; word-wrap: normal; resize: none; color: rgb(0, 0, 0); tab-size: 4; z-index: 0; line-height: 15px !important;"></textarea>

1 2	curl -- socks4 202.113.65.229 : 443 http : //iframe.ip138.com/ic.asp|iconv -fgb2312 curl -- socks5 202.113.65.229 : 443 http : //iframe.ip138.com/ic.asp|iconv -fgb2312

代理服务器地址可以从爬虫代理上获取。

3. linux curl处理cookies

接收cookies:

<textarea class="crayon-plain print-no" data-settings="dblclick" readonly="readonly" style="margin: 0px; padding: 0px 5px; border-width: 0px; width: 598px; overflow: hidden; height: 15px; position: absolute; opacity: 0; box-shadow: none; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; -webkit-box-shadow: none; word-wrap: normal; resize: none; color: rgb(0, 0, 0); tab-size: 4; z-index: 0; line-height: 15px !important;"></textarea>

1	curl - c / tmp / cookies http : //www.baidu.com #cookies保存到/tmp/cookies文件

发送cookies:

<textarea class="crayon-plain print-no" data-settings="dblclick" readonly="readonly" style="margin: 0px; padding: 0px 5px; border-width: 0px; width: 598px; overflow: hidden; height: 30px; position: absolute; opacity: 0; box-shadow: none; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; -webkit-box-shadow: none; word-wrap: normal; resize: none; color: rgb(0, 0, 0); tab-size: 4; z-index: 0; line-height: 15px !important;"></textarea>

1 2	curl - b "key1=val1;key2=val2;" http : //www.baidu.com #发送cookies文本 curl - b / tmp / cookies http : //www.baidu.com #从文件中读取cookies

4. linux curl发送数据：

linux curl get方式提交数据：

<textarea class="crayon-plain print-no" data-settings="dblclick" readonly="readonly" style="margin: 0px; padding: 0px 5px; border-width: 0px; width: 598px; overflow: hidden; height: 15px; position: absolute; opacity: 0; box-shadow: none; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; -webkit-box-shadow: none; word-wrap: normal; resize: none; color: rgb(0, 0, 0); tab-size: 4; z-index: 0; line-height: 15px !important;"></textarea>

1	curl - G - d "name=value&name2=value2" http : //www.baidu.com

linux curl post方式提交数据：

<textarea class="crayon-plain print-no" data-settings="dblclick" readonly="readonly" style="margin: 0px; padding: 0px 5px; border-width: 0px; width: 598px; overflow: hidden; height: 30px; position: absolute; opacity: 0; box-shadow: none; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; -webkit-box-shadow: none; word-wrap: normal; resize: none; color: rgb(0, 0, 0); tab-size: 4; z-index: 0; line-height: 15px !important;"></textarea>

1 2	curl - d "name=value&name2=value2" http : //www.baidu.com #post数据 curl - d a = b & c = d & txt @ / tmp / txt http : //www.baidu.com  #post文件

以表单的方式上传文件：

<textarea class="crayon-plain print-no" data-settings="dblclick" readonly="readonly" style="margin: 0px; padding: 0px 5px; border-width: 0px; width: 598px; overflow: hidden; height: 15px; position: absolute; opacity: 0; box-shadow: none; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; -webkit-box-shadow: none; word-wrap: normal; resize: none; color: rgb(0, 0, 0); tab-size: 4; z-index: 0; line-height: 15px !important;"></textarea>

1	curl - F file = @ / tmp / me . txt http : //www.aiezu.com

相当于设置form表单的method="POST"和enctype='multipart/form-data'两个属性。

5. linux curl http header处理：

设置http请求头信息：

<textarea class="crayon-plain print-no" data-settings="dblclick" readonly="readonly" style="margin: 0px; padding: 0px 5px; border-width: 0px; width: 598px; overflow: hidden; height: 60px; position: absolute; opacity: 0; box-shadow: none; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; -webkit-box-shadow: none; word-wrap: normal; resize: none; color: rgb(0, 0, 0); tab-size: 4; z-index: 0; line-height: 15px !important;"></textarea>

1 2 3

curl - A "Mozilla/5.0 Firefox/21.0" http : //www.baidu.com #设置http请求头User-Agent curl - e "http://pachong.org/" http : //www.baidu.com #设置http请求头Referer curl - H "Connection:keep-alive \n User-Agent: Mozilla/5.0" http : //www.aiezu.com

设置http响应头处理：

<textarea class="crayon-plain print-no" data-settings="dblclick" readonly="readonly" style="margin: 0px; padding: 0px 5px; border-width: 0px; width: 598px; overflow: hidden; height: 30px; position: absolute; opacity: 0; box-shadow: none; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; -webkit-box-shadow: none; word-wrap: normal; resize: none; color: rgb(0, 0, 0); tab-size: 4; z-index: 0; line-height: 15px !important;"></textarea>

1 2	curl - I http : //www.aiezu.com #仅仅返回header curl - D / tmp / header http : //www.aiezu.com #将http header保存到/tmp/header文件

6. linux curl认证：

<textarea class="crayon-plain print-no" data-settings="dblclick" readonly="readonly" style="margin: 0px; padding: 0px 5px; border-width: 0px; width: 598px; overflow: hidden; height: 30px; position: absolute; opacity: 0; box-shadow: none; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; -webkit-box-shadow: none; word-wrap: normal; resize: none; color: rgb(0, 0, 0); tab-size: 4; z-index: 0; line-height: 15px !important;"></textarea>
