使用RestClient和Sinatra发送和接收JSON

Question

我试图通过RestClient ruby​​ API将JSON数据发送到Sinatra应用程序.

在客户端(client.rb)(使用RestClient API)

response = RestClient.post 'http://localhost:4567/solve', jdata, :content_type => :json, :accept => :json

在服务器(Sinatra)

require "rubygems"
require "sinatra"


post '/solve/:data' do 

  jdata = params[:data]

  for_json = JSON.parse(jdata)

end

我收到以下错误

/Library/Ruby/Gems/1.8/gems/rest-client-1.5.1/lib/restclient/abstract_response.rb:53:in `return!': Resource Not Found (RestClient::ResourceNotFound)
    from /Library/Ruby/Gems/1.8/gems/rest-client-1.5.1/lib/restclient/request.rb:193:in `process_result'
    from /Library/Ruby/Gems/1.8/gems/rest-client-1.5.1/lib/restclient/request.rb:142:in `transmit'
    from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/net/http.rb:543:in `start'
    from /Library/Ruby/Gems/1.8/gems/rest-client-1.5.1/lib/restclient/request.rb:139:in `transmit'
    from /Library/Ruby/Gems/1.8/gems/rest-client-1.5.1/lib/restclient/request.rb:56:in `execute'
    from /Library/Ruby/Gems/1.8/gems/rest-client-1.5.1/lib/restclient/request.rb:31:in `execute'
    from /Library/Ruby/Gems/1.8/gems/rest-client-1.5.1/lib/restclient.rb:72:in `post'
    from client.rb:52

我想要的是发送JSON数据并使用RestClient和Sinatra接收JSON数据.但是无论我尝试什么,我都会收到上述错误.我坚持了3个小时.请帮忙

Answer 1

您的sinatra应用程序与http:// localhost:4567/solve URL 不匹配,因此它从您的服务器返回404.

您需要通过示例更改您的sinatra应用程序:

require "rubygems"
require "sinatra"


post '/solve/?' do 
  jdata = params[:data]
  for_json = JSON.parse(jdata)
end

您的RestClient请求也有问题.您需要定义jdata的params名称.

response = RestClient.post 'http://localhost:4567/solve', {:data => jdata}, {:content_type => :json, :accept => :json}
