如何通过curl调用使用HTTP请求发送头文件？
我希望在Linux机器上发送一个头部到我的Apache服务器。 我怎样才能通过curl调用来实现这一点？
man curl ：
-H/--header <header> (HTTP) Extra header to use when getting a web page. You may specify any number of extra headers. Note that if you should add a custom header that has the same name as one of the internal ones curl would use, your externally set header will be used instead of the internal one. This allows you to make even trickier stuff than curl would normally do. You should not replace internally set headers without knowing perfectly well what you're doing. Remove an internal header by giving a replacement without content on the right side of the colon, as in: -H "Host:". curl will make sure that each header you add/replace get sent with the proper end of line marker, you should thus not add that as a part of the header content: do not add newlines or carriage returns they will only mess things up for you. See also the -A/--user-agent and -e/--referer options. This option can be used multiple times to add/replace/remove multi- ple headers.
例：
curl --header "X-MyHeader: 123" www.google.com
您可以看到通过添加-v选项发送的请求。
得到：
与JSON：
curl -i -H "Accept: application/json" -H "Content-Type: application/json" http://hostname/resource
用XML：
curl -H "Accept: application/xml" -H "Content-Type: application/xml" -X GET http://hostname/resource
POST：
发布数据：
curl --data "param1=value1¶m2=value2" http://hostname/resource
对于file upload：
curl --form "fileupload=@filename.txt" http://hostname/resource
RESTful HTTP Post：
curl -X POST -d @filename http://hostname/resource
登入网站（auth）：
curl -d "username=admin&password=admin&submit=Login" --dump-header headers http://localhost/Login curl -L -b headers http://localhost/
在PHP中
curl_setopt($ch,CURLOPT_HTTPHEADER,array('HeaderName: HeaderValue'));
或者你可以设置多个
curl_setopt($ch,CURLOPT_HTTPHEADER,array('HeaderName: HeaderValue','HeaderName2: HeaderValue2'));
使用-H or --header 。
GET（多个参数）：
curl -X GET "http://localhost:3000/action?result1=gh&result2=ghk"
要么
curl --request GET "http://localhost:3000/action?result1=gh&result2=ghk"
要么
curl "http://localhost:3000/action?result1=gh&result2=ghk"
要么
curl -i -H "Application/json" -H "Content-type: application/json" "http://localhost:3000/action?result1=gh&result2=ghk"
我已经从curl切换到Httpie ; 语法如下所示：
http http://myurl HeaderName:value
如果你想发送你的自定义标题 ，你可以这样做
curl -v -H @{'custom_header'='custom_header_value'} http://localhost:3000/action?result1=gh&result2=ghk
