首先,我正在调用一个javascript ajax函数,它将调用我转到URL时调用的ruby函数:

  

/ CNET

从那里开始,我想从ruby做另一个post调用,我想传递json数据。如何传递json格式的数据以在ruby中执行此调用?

我的javascript代码如下:

$.ajax({
  url: "/cnet",
  type: "get",
  dataType: "json",
  contentType: "application/json",
  data: {netname:netname},
  success: function(data) {
    alert(data);
  }
});

我的红宝石代码如下:实际上,我尝试了两种不同的方式:

1

get '/cnet' do  
  net_name=params[:netname]

  @toSend = {
    "net_name" => net_name
  }.to_json

  uri = URI.parse("http://192.168.1.9:8080/v2.0/networks")
  https = Net::HTTP.new(uri.host,uri.port)
  #https.use_ssl = true
  req = Net::HTTP::Post.new(uri.path, initheader = {'Content-Type' =>'application/json'})
  req['net_name'] = net_name
  req.body = "#{@toSend} "
  res = https.request(req)
  erb net_name
end

2

get '/cnet' do  
  temp="mynet"
  url = URI.parse('http://192.168.1.9:8080/v2.0/networks') 
  params={'net_name'=>temp}
  resp = Net::HTTP.post_form(url, params)
  resp_text = resp.body
  print "======================================================================"
  puts resp_text    
  print "======================================================================"
  erb resp_text
end

如何传递json数据而不是字符串?

非常感谢任何帮助。

你必须将json作为字符串发送:

require 'json'
require 'net/http'

Net::HTTP.start('192.168.1.9', 8080) do |http|
  json = {net_name: 'mynet'}.to_json
  http.post('/v2.0/networks', json, 'Content-Type' => 'application/json') do |response|
    puts response
  end
end
