I'm using the Docker API to get info on containers in JSON format. Basically, I want to do a filter based on label values, but it is not working (just returns all containers). This filter query DOES work if you just use the command line docker, i.e.:
docker ps -a -f label=owner=fred -f label=speccont=true
However, if I try to do the equivalent filter query using the API, it just returns ALL containers (no filtering done), i.e.:
curl -s --unix-socket /var/run/docker.sock http:/containers/json?all=true&filters={"label":["speccont=true","owner=fred"]}
Note that I do uri escape the filters param when I execute it, but am just showing it here unescaped for readability.
Am I doing something wrong here? Or does this seem to be a bug in the Docker API? Thanks for any help you can give!
The correct syntax for filtering containers by label as of Docker API v1.41 is
curl -s -G -X GET --unix-socket /var/run/docker.sock http://localhost/containers/json" \
--data 'all=true' \
--data-urlencode 'filters={"label":["speccont=true","owner=fred"]}'
Note the automatic URL encoding as mentioned in this stackexchange post.
I felt there was a bug with API too. But turns out there is none. I am on API version 1.30.
I get desired results with this call:
curl -sS localhost:4243/containers/json?filters=%7B%22ancestor%22%3A%20%5B%222bab985010c3%22%5D%7D
I got the url escaped string using used above with:
python -c 'import urllib; print urllib.quote("""{"ancestor": ["2bab985010c3"]}""")'
I was pulling my hair out trying to get a command to work. I tried what I thought was a idnetical command, but with curl and it magically worked.
curl -X PUT -d param=value https://example.com/users/username?api_key=keyvalue&api_username=system
python httpie
http PUT https://example.com/users/username.json?api_key=value&api_username=system key=value
Both were validating and returning 200, but the http one did not follow through with changing the value like I was trying to do. Any idea why?
Scenario
Among other things, Powershell 2.0 doesn't have the useful cmdlet Invoke-RestMethod.
I can't upgrade to version 3 and most examples I've found use version 3.
I have found this article, which seems, however, too complicated for my simple scenario.
I need to write a Powershell script that POSTs data in Json format, e.g.
{"Id":5,"Email":"test#com","DataFields":null,"Status":0}
What I've tried
I am able to GET data. This is one of the scripts I have tried.
curl -v --user username:password https://api.dotmailer.com/v2/account-info
But, when I try to POST, I can't figure out where to put the body of the message in the script. This is what I've got so far:
curl -v -X POST -H "Accept: application/json" -H "Content-Type: application/json" -u username:password -d '{"Id":5,"Email":"test#com","OptInType":0,"EmailType":0, "DataFields":null,"Status":0}' https://api.dotmailer.com/v2/contacts
which returns the following error:
{"message":"Could not parse the body of the request based on the content type \"application/json\" ERROR_BODY_DOES_NOT_MATCH_CONTENT_TYPE"}*
Question
Can anyone advise on how to POST Json data from Powershell using cURL?
Any pointers to why I get the error I mentioned in the Waht I've tried section would be much appreciated.
Thanks.
Note that the question is about the curl.exe external program, not about PowerShell's Invoke-WebRequest cmdlet (which, unfortunately, is aliased to curl in later PowerShell versions, preempting calls to the external program unless the .exe extension is explicitly specified (curl.exe ...).
Unfortunately and unexpectedly, you have to \-escape embedded " instances in a string you pass as an argument to an external program.
Therefore, even though:
'{"Id":5,"Email":"test#com","DataFields":null,"Status":0}'
should work, it doesn't, due to a long-standing bug; instead, you must use:
'{\"Id\":5,\"Email\":\"test#com\",\"DataFields\":null,\"Status\":0}'
See this answer for more information.
From curl's man page it appears you need to use -d switch:
curl -v --user username:password -H "Content-Type: application/json" -d '{"Id":5,"Email":"test#com","DataFields":null,"Status":0}' https://api.dotmailer.com/v2/contacts
How to make a request for uploading a file to facebook using graph api in curl
I am making this request but getting Error:
curl https://graph.facebook.com/<id>/photos -F "source=#me.jpg" -d "message=Me" -v
ERR:
Only One Http Request can be Selected
You cannot mix -F and -d options in the same command line. If you want a multipart formpost (which I believe you do) then you need to add all parts with -F, including the "message=Me" part.
Does AppleScript have a way of interacting with REST APIs?
I realize I can
do shell script curl
I would use curl in
do shell script "#curl script here"
If you need help to get the correct curl statement I recommend postman, It helps me really to generate the right code. But remember If you have these: " to put an escape character in front: \".
So for example if i want to do a POST request to
https://api.widerstandsberechner.ch/api.php?firstcolor=red&secondcolor=orange&thirdcolor=yellow&fourthcolor=silver&hasFiveRings=0&resultInText=0
the AppleScript would look like this:
do shell script "curl -X POST -H \"Cache-Control: no-cache\" \"https://api.widerstandsberechner.ch/api.php?firstcolor=red&secondcolor=orange&thirdcolor=yellow&fourthcolor=silver&hasFiveRings=0&resultInText=0\""
And of course you can easy assign the result as a value:
set res to do shell script "curl -X POST -H \"Cache-Control: no-cache\" \"https://api.widerstandsberechner.ch/api.php?firstcolor=red&secondcolor=orange&thirdcolor=yellow&fourthcolor=silver&hasFiveRings=0&resultInText=0\""
Hope this helps!
