如何使用json在Ruby中创建带有标题的Https帖子？
我试过了：
uri = URI.parse("https://...")
https = Net::HTTP.new(uri.host,uri.port)
req = Net::HTTP::Post.new(uri.path)
req['foo'] = bar
res = https.request(req)
puts res.body

问题是json。这解决了我的问题。无论如何，我的问题并不清楚，所以赏金归于Juri
require 'uri'
require 'net/http'
require 'net/https'
require 'json'
@toSend = {
"date" => "2012-07-02",
"aaaa" => "bbbbb",
"cccc" => "dddd"
}.to_json
uri = URI.parse("https:/...")
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['foo'] = 'bar'
req.body = "[ #{@toSend} ]"
res = https.request(req)
puts "Response #{res.code} #{res.message}: #{res.body}"

尝试：
require 'net/http'
require 'net/https'
uri = URI.parse("https://...")
https = Net::HTTP.new(uri.host,uri.port)
https.use_ssl = true
req = Net::HTTP::Post.new(uri.path)
req['foo'] = bar
res = https.request(req)
puts res.body

这是一种使用Net :: HTTP的更简洁方法。如果你只想获得响应并扔掉其他物体，这非常有用。

默认安全示例：
require 'net/http'
require 'net/https'
req = Net::HTTP::Post.new("/some/page.json", {'Content-Type' =>'application/json'})
req.body = your_post_body_json_or_whatever
http = Net::HTTP.new('www.example.com', 443)
http.use_ssl = true
http.ssl_version = :TLSv1 # ruby >= 2.0 supports :TLSv1_1 and :TLSv1_2.
# SSLv3 is broken at time of writing (POODLE), and it's old anyway.
http.verify_mode = OpenSSL::SSL::VERIFY_PEER # please don't use verify_none.
# if you want to verify a server is from a certain signing authority,
# (self-signed certs, for example), do this:
http.ca_file = 'my-signing-authority.crt'
response = http.start {|http| http.request(req) }

它正常工作，您可以像这样传递数据和标题：
header = {header part}
data = {"a"=> "123"}
uri = URI.parse("https://anyurl.com")
https = Net::HTTP.new(uri.host,uri.port)
https.use_ssl = true
req = Net::HTTP::Post.new(uri.path, header)
req.body = data.to_json
res = https.request(req)
puts "Response #{res.code} #{res.message}: #{res.body}"
