Curl Multiple Headers

Posted on by admin



Update: This has been implemented in curl 7.19.0. See @Besworks answer. According to the man page there is no way to keep the original file name except using multiple O´s. Alternatively you could use your own file name. Get the HTTP Headers of a URL # HTTP headers are colon-separated key-value pairs containing information such as user agent, content type, and encoding. Headers are passed between the client and the server with the request or the response. Use the -I option to fetch only the HTTP headers of the specified resource: curl -I -http2 https://www.

  1. I found a lot of examples on how to use simple POST commands in cURL, but I didn't find examples on how to send full HTTP POST commands, which contain: Headers (Basic Authentication) HTTP Params (.
  2. How to send HTTP headers with a cURL GET request? To make a GET request with HTTP headers, use the -H command-line option. You can pass as many HTTP headers with your cURL GET request as you like using the -H command line multiple times.
  3. Curl request with multiple headers; CRUD Operations on Bookmarks.dev API. Create bookmark - POST; Read created resource - GET; Update created resource - PUT; Delete created resource - DELETE; Conclusion; Introduction. In the first part of the blog post I will do a brief introduction to curl and what it can do (HTTP requests with options).

I think you're somehow not doing it right. I simply can't make this fail when
I try to use it.

Why are you using uppercase all over? It makes my head hurt! ;-)

I tried this:

$ cd tests

[ cd'ed into the tests directory ]

$ ./server/sws &

[ started the test WWW server that runs on port 8999 by default]

$ curl localhost:8999/1 -H 'test1: yes' -H 'test2: yes' -H 'Pragma: fake' -H
'Host: lalala' -H 'ACCEPT: woohoo'

[ this fetches the data from test case 1, with an additional set of fun -H
arguments ]

$ cat log/server.input
GET /1 HTTP/1.1
User-Agent: curl/7.10.6 (i686-pc-linux-gnu) libcurl/7.10.6 OpenSSL/0.9.7a ipv6
zlib/1.1.3 GSS
test1: yes
test2: yes
Pragma: fake
Host: lalala
ACCEPT: woohoo

Headers

[ this shows a somewhat older version supporting all this that I claim it
does. Using my dev version gives the same result. ]

> OPENSSL/0.9.7A

Why is the receiver converting everything to uppercase?

I don't understand how this cannot work for you. It works for me, as above.
