I am trying to post a json string using curl in scala. My curl command works fine if executed from linux box but throes an error(("message": "Must provide query string.",) always from scala.
my working curl command in linux:
curl http://laptpad1811:5000/graphql -H "Content-Type: application/json"
-X POST -d '{"query":"mutation
CreateFileReceivedEvent($createFileReceivedEventInput:
CreateFleReceivedEventInput!) { createFileReceivedEvent(input:
$createFileReceivedEventInput) { clientMutationId }}","variables":
{"createFileReceivedEventInput":
{"clientMutationId":"Test","fileReceivedEvent":{"file":
{"fileTrackingId":"83a86c44-66a5-4de0-9b7f-
c6995877279d","name":"textfile_2017-08-21T15:58:45Z","fileType":
{"code":"textfile"}},"eventTimestamp":"2017-08-
21T15:59:30Z"}}},"operationName":"CreateFileReceivedEvent"}'
My scala code:
step1: copying the entire json string(pay load) to txt file
'{"query":"mutation CreateFileReceivedEvent($createFileReceivedEventInput:
CreateFleReceivedEventInput!) { createFileReceivedEvent(input:
$createFileReceivedEventInput) { clientMutationId }}","variables":
{"createFileReceivedEventInput":
{"clientMutationId":"Test","fileReceivedEvent":{"file":
{"fileTrackingId":"83a86c44-66a5-4de0-9b7f-
c6995877279d","name":"textfile_2017-08-21T15:58:45Z","fileType":
{"code":"textfile"}},"eventTimestamp":"2017-08-
21T15:59:30Z"}}},"operationName":"CreateFileReceivedEvent"}'
step2:
val data=fromFile("/usr/test/data.txt").getLines.mkString
step3:
val cmd = Seq("curl", "http://laptpad1811:5000/graphql", "-H",
"'Content-Type:application/json'" ,"-X", "POST", "-d" , data)
step4:
cmd.!!
I get the below error
String =
"{
"errors": [
{
"message": "Must provide query string.",
"stack": "BadRequestError: Must provide query string.\n
I have tried to change " to ' and mutiple combinations of the json string but I always get the same error.
I suspect that your issue is that sys.process doesn't pass commands through the shell (e.g. bash), so quotes that are necessary in the shell become unnecessary in Scala (and get passed through to the command which in the case of Unix-style utilities will probably result in unexpected behavior).
So try:
val cmd = Seq("curl", "http://laptpad1811:5000/graphql", "-H", "Content-Type: application/json", "-X", "POST", "-d", data)
Likewise remove the single quote wrapping from your text file.
I would however, counsel against spawning a curl in Scala and advise using one of the existing http client libraries (I personally like Gigahorse).

In terraform,I am trying to make a PUT call via curl command using null_resource and executing the command in local_exec provisioner. The body of the request is json array.
The command expects the data to be in string format. I have the data as tuple in locals. I am using jsonencode to serialize the tupple to a string and pass to curl. But on jsonencode, the string formed has an additional \ prefixed before each " in json string.
eg. expected json string is:
"[{"key-1" : "value-1", "key-2": "value-2"}]"
But after jsonencode, the formatted string is as follows:
"[{\"key-1\" : \"value-1\", \"key-2\": \"value-2\"}]"
additional backslash is added along with quotes.
Because of the malformed request body, the API returns Bad Request response.
How can we correctly serialize the tupple/list to correct json string in Terraform and pass to curl command?
This is my null_resource:
resource "null_resource" "call_API" {
for_each = { for x in local.array: x.name => {
name = x.name
vars = jsonencode(x.vars)
} }
provisioner "local-exec" {
command = <<EOF
curl -X PUT ${var.url} -d ${each.value.vars} -H 'Content-Type:application/json' -H 'Authorization:${local.bearer_token}'
EOF
}
I think I understand that you want to pass this variable
"[{"key-1" : "value-1", "key-2": "value-2"}]"
You tried to use EOF?
You can do something like that
variable "body" {
type = "string"
}
variable = <<EOF
"[{"key-1" : "value-1", "key-2": "value-2"}]"
EOF
Or with EOT, honestly I don't remember which one work
EDIT:
If the json is not static and you receive it from other module or others, you can try to expand the variable inside the EOFs
body = <<EOF
${var.json}
EOF
I use a curl to get the status of a Jira issue :
result = sh(returnStdout: true, script: """curl -D- -k -u $JIRA_LOGIN:$JIRA_PWD -X GET -H "Content-Type: application/json" $url""")
This returns a String like :
{"expand":"renderedFields,names,schema,operations,editmeta,changelog,versionedRepresentations","id":"*****","self":"*****","key":"*****","fields":{"status":{"self":"*****","description":"Issues in development","iconUrl":"****","name":"DEVELOPMENT","id":"10400","statusCategory":{"self":"****","id":4,"key":"indeterminate","colorName":"yellow","name":"In Progress"}}}}
How I can extract the data "DEVELOPMENT" in this string ? I try to parse it in JSON but it's not working :
status_json = new JsonSlurper().parse(result)
with the error "java.io.NotSerializableException: groovy.json.JsonSlurper"
You can check out the JsonSlurper's documentation:
Jira holds all issue fields under the "fields" key in JSON. So, after you get the JSON, you just need to go to the fields.status.name in order to get "DEVELOPMENT" text.
Here's a simple approach:
def jsonSlurper = new JsonSlurper()
def issueObj = jsonSlurper.parseText('...') // Your Jira response will be here
issueObj.fields.status.name // It will give you the status' name.
I have a shell variable which contains json as follows
{
"test" :"test",
"temp":"temp"
}
This is a part of json that I got when parsed from jq, which is a json parser tool.But when I pass this to curl as a part of post request body, it is getting converted to
'{'
'"test"' ':' 'test,'
'"temp"' ':' 'temp'
'}'
But I want it as
'{
"test" : "test",
"temp" : "temp"
}'
VAL=$(echo "$RET" | jq ".pending[$j].value")
VAL is the variable that will contain the json
I need to pass this VAL as request body to curl
curl -X POST -H "$CONTENT_HEADER" -H "$AUTH_HEADER" http://localhost:8080/testApi -d $VAL
The shell is interpreting it as several arguments. Either quote the expansion (as in -d "$VAL") or pipe it instead of saving it to a variable jq '...' | curl ...
I'm trying to make a HTTP form POST request to http://example.co.uk.
I used curl http://example.co.uk -d #example.json. However it gives me error saying it should only contain single field called application.
example.json file:
{"application":[
{
"name":"John",
"email":"john#example.com",
"github":"https://github.com/john",
"twitter":"https://twitter.com/john",
}
]
}
What's the correct way to do it? Any help will be appreciated. Thanks
You'll need to indicate to the server that the content type is JSON instead of the standard form-encoded data, so use:
curl -H "Content-Type: application/json" http://example.co.uk -d #example.json
Also, your JSON file should be valid JSON i.e. without any ending/redundant , characters, so:
{"application":[
{
"name":"John",
"email":"john#example.com",
"github":"https://github.com/john",
"twitter":"https://twitter.com/john"
}
]
}

I have a very simple 'hello world' Mochiweb server (I just started my introduction into it), which takes a JSON request and sends it back:
'POST' ->
case Path of
"dummy" ->
Data = Req:parse_post(),
Json = proplists:get_value("json", Data),
Struct = mochijson2:decode(Json),
Action_value = struct:get_value(<<"action">>, Struct),
Action = list_to_atom(binary_to_list(A)),
Result = [got_json_request, Action],
DataOut = mochijson2:encode(Result),
Req:ok({"application/json",[],[Result]});
The thing is that when I try to make a request to it with cURL it fails:
curl -i -H "Content-Type: application/json" -H "Accept: application/json" -X POST -d '{"action":"dummy"}' http://localhost:8080/dummy
The Mochiweb log is quite difficult to read, but as I understand the error happens at this line:
Json = proplists:get_value("json", Data)
I have put a couple of io:formats in the code and found out that both Data and Json variables are [] after I make a request with cURL.
On the other hand, when I do a very simple request with cURL:
curl -d '{"action":"dummy"}' http://localhost:8080/dummy
both Data and Json are [{"{\"action\":\"dummy\"}",[]}], but in that case the line Struct = mochijson2:decode(Json) fails.
For some strange reason Mochiweb does not see the JSON data in the POST request in case the header has the "application/json" value.
So, the question is: How do I make a correct POST request with JSON data to a Mochiweb server?
EDIT: Json variable has the undefined value.
Try something along the lines of
Data = Req:recv_body(),
Json = mochijson2:decode(Data),
...
You should at least ensure method post and the content type ahead of this.
This is not about POST nor get.
It's about how you post your data to send to your server
When you send a json data to server, you need to make it as key=value
curl -d "key=value" "http://your.domain.com/path"
Therefore, if you want to post json as '{"action":"dummy"}', for GET request
curl -d "json='{\"action\":\"dummy\"}'" http://localhost:8080/dummy
For POST request as a file,
curl -F "json=#filename.json" http://localhost:8080/dummy
of course, when you send as a file, you need to read the posted file from the server side.
