HTTP GraphQl calls always return 200 - even if the response doesn't suite the request.
I'm trying to do a graphql call and understand if there's an error, like using $? and --fail but it doesn't help because of the always 200 response.
Even if graphql's output isn't according to input and contains error arrays, curl only cares about the http code, which is always 200.
Is there a way for curl to understand a graphql error? Like some kind of built in mechanism in to compare requested input to actual input and understand there's an error?
Perhaps I'm barking on the wrong tree here and should use some command line tool more dedicated to graphql? Thanks.
curl doesn't know anything in particular about GraphQL. You can pipe the output of curl to grep to check for the presence of errors and draw conclusions based on that as necessary.
ex:
curl --request POST \
--header 'content-type: application/json' \
--url http://localhost:4000/ \
--data 'your query data'| grep "errors"

I'm writing a bash script to interface with my ecobee (query info and change settings). I have the authorization all worked out (access token and refresh token) and am now trying to request info from the ecobee. This json parameter list is dynamically created. None of the curl examples in the Developers API Doc seem to work.
I've tried assigning the json to a variable (?json="$selection") and to a file (?json=#"$location"). My latest attempt (hard coding the json and escaping the braces) of the curl is as follows:
response=$(curl -s "https://api.ecobee.com/1/thermostat?json=\{"selection":\{"selectionType":"registered","selectionMatch":null,"includeRuntime":true,"includeSettings":true/}/}" -H "Content-Type: application/json;charset=UTF-8" -H "Authorization: Bearer $access_token")
and I received a null response declare -- response=""
If I have curl read from a file:
{"selection":{"selectionType":"registered","selectionMatch":null,"includeRuntime":true,"includeSettings":true}}
then I receive:
response='{
"status": {
"code": 4,
"message": "Serialization error. Malformed json. Check your request and parameters are valid."
}
}'
Which I assuming it' an escape issue?
Can anyone offer any insight? Again, I thought this would be the easy part. I'm using jq to build my request json. Other alternatives to curl that can better deal with json? I'm limited to bash (which is what I know)
Thanks
To integrate (arbitrary) data into a URL (or URI in general) you need to prepare it using percent-encoding first.
As you have mentioned to use jq to compose that data, you could add #uri to your jq filter to perform the encoding, and use the --raw-output (or -r) option to then output it properly.
For example, jq -r '#uri' applied to your JSON
{
"selection": {
"selectionType": "registered",
"selectionMatch": null,
"includeRuntime": true,
"includeSettings": true
}
}
would output
%7B%22selection%22%3A%7B%22selectionType%22%3A%22registered%22%2C%22selectionMatch%22%3Anull%2C%22includeRuntime%22%3Atrue%2C%22includeSettings%22%3Atrue%7D%7D
which you can use within the query string ?json=….
I am working on Windows10 and tried to load a geojson file into my couchdb via the "curl" command and a POST request in the cmd which looks like that:
C:\Program Files\cURL\bin>curl -d #path-to-my-data\data.geojson -H "Content-type: application/json" -X POST http://127.0.0.1:5984/_utils/database.html?-dbName-
and then I get the following error:
{"error":"method_not_allowed","reason":"Only GET,HEAD allowed"}
On http://couchdb-13.readthedocs.org/en/latest/api-basics/ it is said, that "If you use the an unsupported HTTP request type with a URL that does not support the specified type, a 405 error will be returned, listing the supported HTTP methods."
When I try that with a PUT request, I get the same error.
I validated the json with jsonlint so this should not be the problem.
I tried several tutorials like "Three Steps to CouchDB Heaven …" or "Export & Import a Database with CouchDB" but none of them seems to work.
So I am not sure, where the problem is. Do I need to make changes in my geojson file, or something else?
thanks for your help
The needed curl command just looks like that:
curl -H "Content-Type: application/json" -X POST http://localhost:5984/db -d #C:\Users\Name\Desktop\data.geojson
This is a cUrl command I want to do in Ruby
curl --get 'https://api.twitter.com/1.1/statuses/user_timeline.json' --data 'screen_name=example' --header 'Authorization: OAuth oauth_consumer_key="example", oauth_version="1.0"' --verbose
So far I only know how to GET requests using Net::HTTP but these don't have headers and data like the cUrl command above.
It would be great if someone could tell me how to GET in Ruby with headers and data.
If you don't mind using additional GEMS, try UniRest
I have been able to query rally analytics API using DHC(Dev HTTP Client) with the following POST request
http://rally1.rallydev.com/analytics/v2.0/service/rally/workspace/1234/artifact/snapshot/query.js&API_Key=key123
and body
{
"find": {
"ObjectID": 4321
}
}
Is there any way I can do this from Ruby? I have using 'rest-client' but am only getting errors endlessly (400, 403, ....)
Has anyone been able to do this ?
Is this possible using curl?
It's possible using both curl and ruby. You need to set a ZSESSIONID header value equal to your API Key. Curl example here (randomized Workspace OID and API Key):
curl -X POST \
'https://rally1.rallydev.com/analytics/v2.0/service/rally/workspace/12345678910/artifact/snapshot/query' \
-H 'content-type: application/json' \
-H 'accept: application/json' \
-H 'ZSESSIONID: _m31qjdm43Ou74h0cACk28zgBUOPm50Xtna2PhQ2L22' \
--data '{"find":{"FormattedID": "DE9", "__At": "current"},"fields":true,"start":0,"pagesize":10,"removeUnauthorizedSnapshots":true}' \
--compressed
It is fairly straightforward to do in Ruby also. The following Gists:
Rally Lookback Connection Helper
Rally Lookback Query Example
Contain a Ruby connection helper for connecting to Rally's Lookback API. The second Gist contains an example of using the connection helper along with a hash representing a find query object. The Ruby example uses httpclient gem as opposed to rest-client gem, but the concept is the same.
Has this API changed ? We had a change in our username recently and since then, running the Query example returns {"_rallyAPIMajor":"2","_rallyAPIMinor":"0","Errors":["Not Found"],"Warnings":[]}
for all the queries.
How do you POST a binary variable in curl bash?
#!/usr/bin/env bash
IMAGE=$(curl "http://www.google.com/images/srpr/logo3w.png")
curl --data-binary "$IMAGE" --request "POST" "http://www.somesite.com"
Curl seems to do corrupt the image when uploading.
Curl has the option to write response to disk and then read from it, but it'd be more efficient to do it solely in memory.
Try to eliminate the variable ... as follows:
curl "http://www.google.com/images/srpr/logo3w.png" | curl --data-binary - --request "POST" "http://www.somesite.com"
From the curl man page:
If you start the data with the letter #, the rest should be a file name to read the data from, or - if you want curl to read the data from stdin.
EDIT: From the man page, too:
--raw When used, it disables all internal HTTP decoding of content or transfer encodings and instead makes them passed on unaltered, raw. (Added in 7.16.2)
What happens, if applied on either or both sides?
I had a related problem, where I wanted to dynamically curl a file from a given folder.
curl --data-binary directory/$file --request "POST" "http://www.somesite.com"
did not work - uploaded the string "directory/myFile.jar" instead of the actual file.
Adding the # symbol
curl --data-binary #directory/$file --request "POST" "http://www.somesite.com" fixed it.
