Question

我有以下嵌套哈希：

$installation_settings = {
  :lat => "43.107044",
  :lon => "25.194757",
  :country => "Poland",
  :collector_installation => {
      :people => 3,
      :deviation_from_s => 5,
      :solar_collector_id => 1,
      :collectors_number => 2,
      :monthly_water_consumption => 6000,
      :gas_price => 0.09, 
      :electricity_price => 0.87            
  }
}

我正试图通过ruby发送帖子：

url = "someURL"
uri = URI(url)
res = Net::HTTP.post_form(uri, $installation_settings)
puts res.body

Net :: HTTP.post_form只允许发送简单的哈希（没有嵌套），所以我最终得到带有反斜杠的字符串。

我该如何发送？

Answer 1

The docs说哈希必须是string: string格式。所以嵌套的哈希看起来像：

Net::HTTP.post_form(URI('http://localhost'), 'a': { 'b': '2' })
=> #<Net::HTTPOK 200 OK readbody=true>

Answer 2

我正在使用Ruby的旧版本，所以很遗憾我无法应用Anthony的答案。但是，我找到了另一个可能对某人有帮助的解决方案：

uri = URI(url)
http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = false  
request = Net::HTTP::Post.new(uri.path, {'Content-Type' =>'application/json'})
request.body = installation_hash.to_json
response = http.request(request)

使用嵌套哈希发送ruby帖子
