I have defined a file with name - play.rego
package play
default hello = false
hello {
m := input.message
m == "world"
}
I also have file called -input.json
{ "message": "world"}
I now want to use the policy to evaluate on input data using opa server -
opa run --server
I also then registered the policy using below command -
curl -X PUT http://localhost:8181/v1/policies/play --data-binary #play.rego
and then I run below command for evaluating policy on the query -
curl -X POST http://localhost:8181/v1/policies/v1/data/play --data-binary '{"message": "world"}'
But the server always responds with nothing.
I need help fixing the problem?
The URL of the second request is wrong (should not contain v1/policies), and the v1 API requires you to wrap the input document inside an input attribute. Try:
curl -X POST http://localhost:8181/v1/data/play --data-binary '{"input":{"message": "world"}}'

i'm trying to send a parse.com push notification from ruby 1.8.7.
i got a test working with curl. but with ruby's net::http i'm getting Timeout::Error: Resource temporarily unavailable
how can i debug this? i don't know how to see why the parse server is responding differently or otherwise see what's happening. i tried sending the request to my own server and the headers looked ok to me.
i simplified what i'm doing to this:
http = Net::HTTP.new('api.parse.com', 443)
response = http.post("/1/push", "{\"where\":{},\"data\":{\"alert\":\"Elliot net http json test 1\"}}", {"X-Parse-Application-Id"=>"xxxxx", "Content-Type"=>"application/json", "X-Parse-REST-API-Key"=>"xxxxx"})
the json there is hard to read, it's from:
api_req = {:where => {}, :data => {:alert => "Elliot net http json test 1"}}.to_json
puts api_req
# {"where":{},"data":{"alert":"Elliot net http json test 1"}}
i also tried several other ways of sending a request with net::http. same result.
the curl request that worked was:
curl -X POST \
-H "X-Parse-Application-Id: xxxxxx" \
-H "X-Parse-REST-API-Key: xxxxx" \
-H "Content-Type: application/json" \
-d '{
"where": {},
"data": {
"alert": "Elliot curl test #4"
}
}' \
https://api.parse.com/1/push
i'm not using parse-ruby-client because i ran into problems with dependencies assuming a newer version of ruby. all i need to do is send some simple push notifications, and it seems like this should work without too much trouble.
can anyone help me get this working or tell me how to get some useful info about what's happening to debug?
As per the REST API Developers guide,
All API access is over HTTPS, and accessed via the https://api.parse.com domain.
So all you need to do is to add http.use_ssl = true.
How do I convert the following CURL PUT request to rspec and test the behaviour of JSON parser.
curl -D - -X PUT --data "not json" -H "Content-Type: application/json" http://localhost:3000
And how to check the response? Thank you in advance.
The best is to use vcr gem https://github.com/vcr/vcr
Simply create script like in https://github.com/vcr/vcr#usage but with proper HTTP request.
VCR.use_cassette("json_test") do
req = Net::HTTP::Put.new('http://localhost:3000', 'not json')
req.content_type = 'application/json'
res = Net::HTTP.get_response(req)
end
With this real HTTP request will be recorded once and in rspec local file will be used instead.
You can use the -i option:
-i, --include
(HTTP) Include the HTTP-header in the output. The HTTP-header includes things like server-name, date of the document, HTTP-version and more...

In my sinatra application, I am using following curl command to post a file in route /test.
curl -H "Content-Type: text/xml" -vv -X POST -d file_data=#test.xml
http://localhost:4567/test
At my Sinatra post method I want read file like
post '/test' do
data = params[:file_data] #Here file_data param name of CURL command.
end
But, here data is NULL. How should I configure my CURL command to read file from file_data param ?
curl -F file_data=#/some/file/on/your/local/disk http://localhost:4567/test
from cURL manual:
-F, --form <name=content>
(HTTP) This lets curl emulate a filled-in form in which a user has pressed the submit button. This causes curl to POST data using the Content-Type multipart/form-data according to RFC 2388. This enables uploading of binary files etc. To force the 'content' part to be a file, prefix the file name with an # sign. To just get the content part from a file, prefix the file name with the symbol <. The difference between # and < is then that # makes a file get attached in the post as a file upload, while the < makes a text field and just get the contents for that text field from a file.
for more details: cURL manual
Quick answer: Remove -H "Content-Type: text/xml" and it should work.
The problem is that when a file is sent, the Content-Type header should be multipart/form-data, which curl sets automatically when you use -F. From curls documentation:
-F, --form
(HTTP) This lets curl emulate a filled-in form in which a user has pressed the submit
button. This causes curl to POST data using the Content-Type multipart/form-data according to RFC 2388. This enables uploading of binary files etc.
However, you are overwriting this header with -H, so your app is expecting something that is not a file.
If, in addition to sending the file with curl, you want to include information about its type, you should instead do this:
curl -X POST -F "file_data=#test.xml;type=text/xml" http://localhost:4567/test
(The content type comes after the file name and a semicolon.)
To see how a raw form submission request ends up looking like with multipart/form-data, check the answers to this question.
I am testing my ZF2 Rest Module that is running on localhost, by sending curl POST requests from the same box.
curl -i -X POST -H "Content-Type: Application/json" -d '{username":"xyz","password":"xyz"}' http://localhost/api/login
In the corresponding controller and action, I have tried returning the POST parameters, but an empty array is returned always
var_dump($this->getRequest()); // returns: array(0){}
var_dump($_POST); // returns: array(0){}
If I switch from POST to GET with
curl -i -G -H "Content-Type: Application/json" -d '{username":"xyz","password":"xyz"}' http://localhost/api/login
it actually seems to work
var_dump($_GET); // returns: array(1) {["{"username":"xyz","password":"xyz"}"]=>string(0) ""}
Why is the POST request failing to pass/extract the parameters?
PHP only populates $_POST for form urlencoded POST data. You've explicitly set the content type to JSON, so the PHP way to access this would be:
file_get_contents("php://input");
In ZF2, I believe you want:
$this->getRequest()->getContent();
and in practice, you'll probably want to run this through json_decode().
I am using cURL command line utility to send HTTP POST to a web service. I want to include a file's contents as the body entity of the POST. I have tried using -d </path/to/filename> as well as other variants with type info like --data </path/to/filename> --data-urlencode </path/to/filename> etc... the file is always attached. I need it as the body entity.
I believe you're looking for the #filename syntax, e.g.:
strip new lines
curl --data "#/path/to/filename" http://...
keep new lines
curl --data-binary "#/path/to/filename" http://...
curl will strip all newlines from the file. If you want to send the file with newlines intact, use --data-binary in place of --data
I know the question has been answered, but in my case I was trying to send the content of a text file to the Slack Webhook api and for some reason the above answer did not work. Anywho, this is what finally did the trick for me:
curl -X POST -H --silent --data-urlencode "payload={\"text\": \"$(cat file.txt | sed "s/\"/'/g")\"}" https://hooks.slack.com/services/XXX
In my case, # caused some sort of encoding problem, I still prefer my old way:
curl -d "$(cat /path/to/file)" https://example.com
curl https://upload.box.com/api/2.0/files/3300/content -H "Authorization: Bearer $access_token" -F file=#"C:\Crystal Reports\Crystal Reports\mysales.pdf"
