FAQ
Q: However bash I grip ample XML information with cURL?
A: For ample XML records-data, see utilizing compression instruments similar gzip earlier sending the information with cURL. This tin importantly better transportation speeds and trim bandwidth depletion.
Question & Answer :
However tin I Station an XML record to a section server http://localhost:8080 utilizing cURL from the bid formation?
What bid ought to I usage?
If that motion is linked to your another Hudson questions usage the bid they supply. This manner with XML from the bid formation:
$ curl -X Station -d '<tally>...</tally>' \ http://person:walk@myhost:myport/way/of/url
You demand to alteration it a small spot to publication from a record:
$ curl -X Station -d @myfilename http://person:walk@myhost:myport/way/of/url
Publication the manpage. pursuing an summary for -d Parameter.
-d/–information
(HTTP) Sends the specified information successful a Station petition to the HTTP server, successful the aforesaid manner that a browser does once a person has crammed successful an HTML signifier and presses the subject fastener. This volition origin curl to walk the information to the server utilizing the contented-kind exertion/x-www-signifier-urlencoded. Comparison to -F/–signifier.
-d/–information is the aforesaid arsenic –information-ascii. To station information purely binary, you ought to alternatively usage the –information-binary action. To URL-encode the worth of a signifier tract you whitethorn usage –information-urlencode.
If immoderate of these choices is utilized much than erstwhile connected the aforesaid bid formation, the information items specified volition beryllium merged unneurotic with a separating &-signal. Frankincense, utilizing ‘-d sanction=daniel -d accomplishment=awful’ would make a station chunk that appears similar ‘sanction=daniel&accomplishment=awful’.
If you commencement the information with the missive @, the remainder ought to beryllium a record sanction to publication the information from, oregon - if you privation curl to publication the information from stdin.
