使用rails运行HTTP请求

Question

我好久没用过Rails了。我现在有一个卷曲请求，如下所示

curl -X GET -H 'Authorization: Element TOKEN, User TOKEN' 'https://api.cloud-elements.com/elements/api-v2/hubs/marketing/ping' 

我所要做的就是能够在rails控制器内部运行这个请求，但对于HTTP请求，我缺乏理解，这使我无法理解如何最好地处理这个请求。提前谢谢。

Answer 1

对于HTTP请求，请使用此方法：

  def api_request(type , url, body=nil, header =nil )
    require "net/http"
    uri = URI.parse(url)
    case type
    when :post
      request = Net::HTTP::Post.new(uri)
      request.body = body
    when :get
      request = Net::HTTP::Get.new(uri)
    when :put
      request = Net::HTTP::Put.new(uri)
      request.body = body
    when :delete
      request = Net::HTTP::Delete.new(uri)
    end
    request.initialize_http_header(header)
    #request.content_type = 'application/json'
    response = Net::HTTP.start(uri.host, uri.port, :use_ssl => uri.scheme == 'https') {|http| http.request request}
  end

你的例子是：

api_request(:get, "https://api.cloud-elements.com/elements/api-v2/hubs/marketing/ping",nil, {"Authorization" => "Element TOKEN, User TOKEN" })

它将类似于下面的内容。请注意，连接将被阻塞，因此它可以根据远程主机返回HTTP响应的速度和发出的请求数量来绑定服务器。

require 'net/http'

# Let Ruby form a canonical URI from our URL
ping_uri = URI('https://api.cloud-elements.com/elements/api-v2/hubs/marketing/ping')

# Pass the basic configuration to Net::HTTP
# Note, this is not asynchronous. Ruby will wait until the HTTP connection
# has closed before moving forward
Net::HTTP.start(ping_uri.host, ping_uri.port, :use_ssl => true) do |http|
  # Build the request using the URI as a Net::HTTP::Get object
  request = Net::HTTP::Get.new(ping_uri)
  # Add the Authorization header
  request['Authorization'] = "Element #{ELEMENT_TOKEN}, User #{user.token}"

  # Actually send the request
  response = http.request(request)
  # Ruby will automatically close the connection once we exit the block
end

一旦块退出，您就可以根据需要使用response对象。response对象始终是Net::HTTPResponse的子类(或子类的子类)，您可以使用response.is_a? Net::HTTPSuccess来检查2xx响应。响应的实际主体将以字符串形式在response.body中。
