Sending Array of Json objects in ruby on rails

Question

I want to send an array of JSON objects in a put request body.

JSON body:

[
 {
    "a":1,
    "b":2
 },
 {
    "a":2,
    "b":1
 }
]

I am using HTTP::put to make the request. I send data in the Json as a hash.

put("url", data: json)

But, this causes problems as on the client side it is decoded as :

[
 "data":[{
    "a":1,
    "b":2
 },
 {
    "a":2,
    "b":1
 }]
]

How do I send the Json without hashing or is there any way to get the values out of the hash before sending??

Answer 1

Try to define Content-Type :

json_data = '[{"a":1,"b":2},{"a":2,"b":1 }]'
hash_body = JSON.parse json_data
uri = URI.parse('https://www.google.com/api/something')

request = Net::HTTP::Put.new(uri.request_uri, 'Content-Type' => 'application/json')
request.body = hash_body
response = http.request(request)

Cheers!

We couldn't use HTTP::Put.new because of some parameters that were set internally. We solved it by adding a method in the Her library that in turn uses Faraday to make the request. I am posting the method used here.

      response = self.use_api.connection.put do |req|
        req.url url
        req.headers['Content-Type'] = 'application/json'
        req.body = json
      end

I am not sure if this is the best method or not.
