使用 Net/http 以 JSON 格式发布 Ruby 数据

Question

我有这个 ruby 文件：

require 'net/http'
require 'json'
require 'uri'
    #test data

newAcctJson ='{
  "type": "Credit Card",
  "nickname": "MoreTesting",
  "rewards": 2,
  "balance": 50
}'

    #creates a new account
def createAcct(custID, json)
    url = "http://api.reimaginebanking.com:80/customers/#{custID}/accounts?key=#{APIkey}"
    uri = URI.parse(url)
    http = Net::HTTP.new(uri.host, uri.port)
    myHash = JSON.parse(json)
    resp = Net::HTTP.post_form(uri, myHash)
    puts(resp.body)
end

它试图创建一个新帐户。但是我得到 code: 400, invalid fields in account。我独立测试了数据，所以我（相对）确定 json 本身的格式没有错误；问题在于尝试以 post_Form 要求的散列格式提交数据。有谁知道使用ruby直接postjson数据而不先转换为散列的方法吗？

Answer 1

像这样创建一个请求对象：

request = Net::HTTP::Post.new(uri.request_uri, 
          'Content-Type' => 'application/json')
request.body = newAcctJson
resp = http.request(request)

结合问题中的代码和@DVG 的出色回答：

require 'net/http'
#require 'json' - not needed for the example
require 'uri'

#test data
newAcctJson ='{
  "type": "Credit Card",
  "nickname": "MoreTesting",
  "rewards": 2,
  "balance": 50
}'

#creates a new account
def createAcct(custID, json)
  url = "http://api.reimaginebanking.com:80/customers/#{custID}/accounts?key=#{APIkey}"
  uri = URI.parse(url)
  http = Net::HTTP.new(uri.host, uri.port)

  request = Net::HTTP::Post.new(
    uri.request_uri, 
    'Content-Type' => 'application/json'
  )
  request.body = newAcctJson

  response = http.request(request)
  puts(response.body)
end
