使用Net / http发布JSON格式的Ruby数据

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 

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本身的格式不正确; 问题在于尝试以post_Form所需的散列格式提交数据。 有没有人知道如何使用ruby直接发布json数据而不先转换为哈希？

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) 

Answer 2

要结合问题中的代码和@ DVG的优秀答案：

 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
