Comment envoyer un en-tête en utilisant une requête HTTP via un appel curl?

Je souhaite envoyer un en-tête à mon serveur Apache sur une machine Linux. Comment puis-je y parvenir via un appel curl?

man curl :

  -H/--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 sortingckier 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.

Exemple:

 curl --header "X-MyHeader: 123" www.google.com 

Vous pouvez voir la requête envoyée en ajoutant l’option -v .

OBTENIR:

avec JSON:

 curl -i -H "Accept: application/json" -H "Content-Type: application/json" http://hostname/resource 

avec XML:

 curl -H "Accept: application/xml" -H "Content-Type: application/xml" -X GET http://hostname/resource 

POSTER:

Pour poster des données:

 curl --data "param1=value1&param2=value2" http://hostname/resource 

Pour le téléchargement de fichier:

 curl --form "[email protected]" http://hostname/resource 

RESTful HTTP Post:

 curl -X POST -d @filename http://hostname/resource 

Pour vous connecter à un site (auth):

 curl -d "username=admin&password=admin&submit=Login" --dump-header headers http://localhost/Login curl -L -b headers http://localhost/ 

En PHP :

 curl_setopt($ch, CURLOPT_HTTPHEADER, array('HeaderName:HeaderValue')); 

ou vous pouvez définir plusieurs:

 curl_setopt($ch, CURLOPT_HTTPHEADER, array('HeaderName:HeaderValue', 'HeaderName2:HeaderValue2')); 

Utilisez -H or --header .

GET (plusieurs parameters):

 curl -X GET "http://localhost:3000/action?result1=gh&result2=ghk" 

ou

 curl --request GET "http://localhost:3000/action?result1=gh&result2=ghk" 

ou

 curl "http://localhost:3000/action?result1=gh&result2=ghk" 

ou

 curl -i -H "Application/json" -H "Content-type: application/json" "http://localhost:3000/action?result1=gh&result2=ghk" 

Je suis passé de curl à Httpie ; la syntaxe ressemble à:

 http http://myurl HeaderName:value 

Si vous souhaitez envoyer vos en- têtes personnalisés , vous pouvez le faire de la manière suivante:

 curl -v -H @{'custom_header'='custom_header_value'} http://localhost:3000/action?result1=gh&result2=ghk
