What is counterpart of raw.githubusercontent in gitlab? - gitlab

How to view unprocessed versions of files? I want to use it for curl install script, but didn't find what counterpart is in gitlab.

The following schema is used in gitlab: https://gitlab.com/<group>/<repository>/-/raw/<branch>/<file>
You will probably have to use the gitlab api because your request has to be authorized.
Update
As iugo commented a curl request against this url https://gitlab.com/<group>/<repository>/-/raw/<branch>/<file> redirects.
To get the raw file we need to use the endpoint 'Get raw file from repository' from Repository files API:
curl --header "PRIVATE-TOKEN:<token>" "https://<server>/api/v4/projects/<project-id>/repository/files/<path-to-file>?ref=<branch>"
As output we get the the content (base64 encoded) of the requested file and additional metadata. To get the raw content we need to clip the content part of the returned json and decode it.
To clip the content part we could use jq:
jq -r '.content'
--raw-output / -r With this option, if the filter's result is a string then it will be written directly to standard output rather than being
formatted as a JSON string with quotes.
To decode the encoded content we could use base64
base64 -d > file
-d, --decode Decode data.
In summary, the following should be executed:
curl --header "PRIVATE-TOKEN:<token>" "https://<server>/api/v4/projects/<project-id>/repository/files/<path-to-file>?ref=<branch>" | jq -r '.content' | base64 -d > file

trying to curl with a file into request and failing [duplicate]

I need to make a POST request via cURL from the command line. Data for this request is located in a file. I know that via PUT this could be done with the --upload-file option.
curl host:port/post-file -H "Content-Type: text/xml" --data "contents_of_file"
You're looking for the --data-binary argument:
curl -i -X POST host:port/post-file \
-H "Content-Type: text/xml" \
--data-binary "#path/to/file"
In the example above, -i prints out all the headers so that you can see what's going on, and -X POST makes it explicit that this is a post. Both of these can be safely omitted without changing the behaviour on the wire. The path to the file needs to be preceded by an # symbol, so curl knows to read from a file.
I need to make a POST request via Curl from the command line. Data for this request is located in a file...
All you need to do is have the --data argument start with a #:
curl -H "Content-Type: text/xml" --data "#path_of_file" host:port/post-file-path
For example, if you have the data in a file called stuff.xml then you would do something like:
curl -H "Content-Type: text/xml" --data "#stuff.xml" host:port/post-file-path
The stuff.xml filename can be replaced with a relative or full path to the file: #../xml/stuff.xml, #/var/tmp/stuff.xml, ...
If you are using form data to upload file,in which a parameter name must be specified , you can use:
curl -X POST -i -F "parametername=#filename" -F "additional_parm=param2" host:port/xxx
Most of answers are perfect here, but when I landed here for my particular problem, I have to upload binary file (XLSX spread sheet) using POST method, I see one thing missing, i.e. usually its not just file you load, you may have more form data elements, like comment to file or tags to file etc as was my case. Hence, I would like to add it here as it was my use case, so that it could help others.
curl -POST -F comment=mycomment -F file_type=XLSX -F file_data=#/your/path/to/file.XLSX http://yourhost.example.com/api/example_url
I was having a similar issue in passing the file as a param. Using -F allowed the file to be passed as form data, but the content type of the file was application/octet-stream. My endpoint was expecting text/csv.
You are able to set the MIME type of the file with the following syntax:
-F 'file=#path/to/file;type=<MIME_TYPE>
So the full cURL command would look like this for a CSV file:
curl -X POST -F 'file=#path/to/file.csv;type=text/csv' https://test.com
There is good documentation on this and other options here: https://catonmat.net/cookbooks/curl/make-post-request#post-form-data
I had to use a HTTP connection, because on HTTPS there is default file size limit.
https://techcommunity.microsoft.com/t5/IIS-Support-Blog/Solution-for-Request-Entity-Too-Large-error/ba-p/501134
curl -i -X 'POST' -F 'file=#/home/testeincremental.xlsx' 'http://example.com/upload.aspx?user=example&password=example123&type=XLSX'

Downloading json file from json file curl

I have a json file with the structure seen below:
{
url: "https://mysite.com/myjsonfile",
version_number: 69,
}
This json file is accessed from mysite.com/myrootjsonfile
I want to run a load data script to access mysite.com/myrootjsonfile and load the json content from the url field using curl and save the resulting content to local storage.
This is my attempt so far.
curl -o assets/content.json 'https://mysite.com/myrootjsonfile' | grep -Po '(?<="url": ")[^"]*'
unfortunately, instead of saving the content from mysite.com/myjsonfile its saving the content from above: mysite.com/myrootjsonfile. Can anyone point out what i might be doing wrong? Bear in mind in a completely new to curl. Thanks!
It is saving the content from myrootjsonfile because that is what you are telling curl to do - to save that file to the location assets/content.json, and then greping stdin, which is empty. You need to use two curl commands, one to download the root file (and process it to find the URL of the second), and the second to download the actual content you want. You can use command substitution for this:
my_url=$(curl https://mysite.com/myrootjsonfile | grep -Po '(?<=url: )[^,]*')
curl -o assets/content.json "$my_url"
I also changed the grep regex - this one matches a string of non-comma characters which follow after "url: ".
Assuming you wished to save the file to assets/content.json, note that flags are case sensitive.
Use -o instead of -O to redirect the output to assets/content.json.

Curl show Content-Type only

I was wondering if it is possible to use curl to only show the content-type of the response header.
I want to check if the content-type is text/html for example before downloading instate of downloading the file and then find out it is application/pdf.
I used the example below in the hope that it would return the document if it is valid for me and else do nothing or something! The sample below just prints the full content of the page.
curl -F "type=text/html" www.google.nl
But If i do something like the example below it still downloads the whole thing, and I don't think that is right...
curl -F "type=text/html" http://www.axmag.com/download/pdfurl-guide.pdf
Many thanks :D
Option -F is for forms. Instead you want to send a HEAD request for retrieving only the response header without the response body by using option -I.
To display an URL's content type:
curl -s -I www.google.nl | grep -i "^Content-Type:"
Here option -s is added for silent mode for excluding the progress meter and error messages.
You can also specify the Accept header in your HTTP request. This header is used to accept only specific content types:
curl -s -H "Accept: text/html" http://www.axmag.com/download/pdfurl-guide.pdf
But the disadvantage is that most webservers will serve you an error page which also has the content type text/html. Hence you will still get a HTML file.
You can use the "-w" option too, with the "content-type" parameter:
curl -s -o /dev/null -w '%{content_type}' 'google.com'
Where:
-s: Silent mode, dont send any more to screen
-o: Output to file, and in this case, sends to /dev/null
-w: Where you show only with you want, in this case, content type

How can I send a file's contents as a POST parameter using cURL?

I'm trying to use cURL to POST the contents of a file, as if I'd pasted that contents in to an html textarea. That's to say I don't want to upload the file, I just want a post parameter called foo to be filled with text from a file called bar.txt. bar.txt's contents may include newlines, quotes, and so on.
Is this possible?
Thanks.
Edit: I found out how to do it in the end:
curl --data-urlencode "foo#bar.txt" http://example.com/index.php
This will take the contents of the file bar.txt, url encode it, place the resultant string in a parameter called foo in a POST request of http://example.com/index.php.
I can't speak to whether the solutions others have suggested will work or not, but the one above seems like the best way.
You can by doing something like:
$ curl --data "foo:$(cat foo.txt)" http://localhost/yourfile.php
Note that you'll probably want to encode the file, as cacheguard said. To encode it in base64, just modify the previous command like this:
$ curl --data "foo:$(cat foo.txt | base64)" http://localhost/yourfile.php
You should encode/decode the content of your file (for instance by using the base64 command under Linux).
file foo.txt:
8<----------------------------
Hello World
I am a Secure Web Gateway
8<----------------------------
base64 foo.txt | base64 -d

How do I POST LF with curl command line tool?

I'm trying to POST to the HTTP gateway of an SMS provider (Sybase 365) using CURL from a Linux shell script.
I need to pass the following data (note the [ ] and LF characters)
[MSISDN]
List=+12345678
[MESSAGE]
Text=Hello
[END]
If I submit a file using the -F parameter, CURL removes the LF e.g.
curl -F #myfile "http://www.sybase.com/..."
results in this at the server (which is rejected)
[MSISDN]List=+12345678[MESSAGE]Text=Hello[END]
Is there anything I can do to avoid this or do I need an alternative tool?
I'm using a file containing my data for testing but I'd like to avoid that in practice and POST directly from the script.
Try using --data-binary instead of -d(ata-ascii).
From the manual:
--data-binary (HTTP) This posts data in a similar manner as --data-ascii does, although when using this option the entire context of the posted data is kept as-is.
If you want to post a binary file without the strip-newlines feature of the --data-ascii option, this is for you. If this option is used several times, the ones following the first will append data.
ETA: oops, I should read the question more closely. You're using -F, not -d. But --data-binary may be still be worth a shot.
Probably a silly thought, but I don't suppose it actually requires CRLF instead of just LF?
Alternatively, have you tried using the --data-binary option instead of -F?
I've got this working using -d
request=`printf "[MSISDN]\nList=$number\n[MESSAGE]\nText=$message\n[END]\n"`
response=`curl -s -u $username:$password -d "$request" http://www.sybase.com/...`
Curiously, if I use -d #myfile (where myfile contains LF separated text), it doesn't work.
I also tried --data-binary without success.
curl "url" --data-binary #myfile
posts new lines in the data [tested on curl 7.12.1]
