What is the difference between this two curl calls:
curl -X POST -d "/path/file.txt" http://api-path
curl -X POST -d "#/path/file.txt" http://api-path
The first form sends the string "/path/file.txt" as data, probably not what you want. The # makes curl interpret it as a filename to read from. See http://curl.haxx.se/docs/manpage.html, search for the "--data" option.

I'm trying to explore the curl connect or retrieve the data with query API link but when I run my GET command in curl it runs without any error shown in -vv but the process stop. below the actual statement at the end of the posted process, may I know if this is normal or I need to add an additional arguments or parameters on my command for me to retrieve the data? If yes may I know how to do it?
Connection #1 to host myserver.com left intact
My command
curl -vv -k -X GET -H --user user123:password1 -H "Accept: application/json" https://myapplink/statement/EXE=sample
How can I send POST request with a csv or a text file to the server running on a localhost using cURL.
I have tried curl -X POST -d #file.csv http://localhost:5000/upload but I get
{
"message": "The browser (or proxy) sent a request that this server could not understand."
}
My server is flask_restful API. Thanks a lot in advance.
There are many alternate ways to accomplish this. One way is
I have used the following:
curl -F ‘data=#<file_location>’ <URL>
Eg. curl -F data=#data.csv localhost:5000/h
Your command can also be changed slightly like this
curl -X POST -H 'Content-Type: text/csv' -d #file.csv http://localhost:5000/upload
The above is one of the many ways.It can be sent either as a part of form or data, or multipart, etc. You can refer Medium Post
Curl's default Content-Type is application/x-www-form-urlencoded so your problem is probably that the data you are POSTing is not actually form data. It might work if you set the content type header properly:
-H "Content-Type: text/csv"
Though it does depend on the server.
I have a cURL call that I'm trying to use to send file data to a remote server.
curl -X POST -u username:password -d 'data=#/path/to/file.ext&version=2&action=Parse' http://fqdn.to.server.i.control/Parser.cgi
curl -X POST -u username:password -d 'data=#localFile.ext&version=2&action=Parse' http://fqdn.to.server.i.control/Parser.cgi
cat file.ext | curl -X POST -u username:password -d 'data=#-&version=2&action=Parse' http://fqdn.to.server.i.control/Parser.cgi
The file contents are URI encoded already. Using Perl and CGI on the server side.
My problem is that when the server tries to access that "data" line, value I have is only "file.ext" - the path is stripped out and the file's contents are not used ($cgi->param("data") is just "file.ext", "localFile.ext" or "-" respectively).
Any indication as to what I'm doing wrong?
#MattJacob was correct; my syntax was wrong. data=#... should have been #... and the data= portion should have been in the file. Boy am I thick.
Is there a way to use curl to do a multipart/form-data post and specify that the data is application/json? It doesn't have to be curl.
This is what I use, and it works fine
curl -v -H "Content-Type:multipart/form-data"
-F "someName={\"your\":\"json\"};type=application/json"
Note: I'm on Windows, hence the requirement for double quotes
Or
-F "someName=#someJsonFile.json;type=application/json"
I've been having trouble acquiring and changing some of the basic data available from the Nest thermostat.
Using a command line, how can I get or change individual settings or values on my thermostat?
This is a compilation from several users explaining how to retrieve or change some basic information with some of my own experiences added in. Wherever I use <VALUE>, replace that with the applicable information in your setup. If you're using Windows, you'll need something like git-scm.
The following a part of the authentication process. You'll need to have a client already made on Nest's developer page and followed the provided authorization URL to get your auth code. Run this line to get an access token:
curl --data 'code=<AUTH CODE>&client_id=<CLIENT ID>&client_secret=<CLIENT SECRET>&grant_type=authorization_code' https://api.home.nest.com/oauth2/access_token
To fetch some information about the thermostats associated with the authorization code:
curl -v -L https://developer-api.nest.com/devices/thermostats?auth=<AUTH CODE>
To fetch some information about a specific thermostat:
curl -v -L https://developer-api.nest.com/devices/thermostats/<THERMOSTAT ID>?auth=<AUTH CODE>
To fetch the target temperature in F from the specified thermostat. You can replace target_temperature_f with any other value listed under thermostat on Nest's API reference:
curl -v -L https://developer-api.nest.com/devices/thermostats/<THERMOSTAT ID>/target_temperature_f?auth=<AUTH CODE>
To change the target_temperature_f:
curl -v -L -X PUT "https://developer-api.nest.com/devices/thermostats/<THERMOSTAT ID>/target_temperature_f?auth=<AUTH CODE>" -H "Content-Type: application/json" -d "65"
To change the specific structure to away. The value here is a string so be sure to include the single quotes:
curl -v -L -X PUT "https://developer-api.nest.com/structures/<STRUCTURE ID>/away?auth=<AUTH_TOKEN>" -H "Content-Type: application/json" -d '"away"'
