Question

我正在尝试通过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: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应用与http://localhost:4567/solve网址不匹配，因此它会从您的服务器返回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的参数名称。

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

试试这个：

jdata = {:key => 'I am a value'}.to_json    
response = RestClient.post 'http://localhost:4567/solve', :data => jdata, :content_type => :json, :accept => :json

然后试试这个：

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

我没有测试它，但也许你应该将json数据作为值发送而不是密钥。您的数据可能如下所示：{：key =＆gt; '我是一个价值'} =＆gt;零。您的数据不一定必须在URL中。您不需要/ solve /：data url。 POST值不会在url中发送调试路径中收到的内容的好方法是打印参数：

puts params

希望这有帮助！

使用RestClient和Sinatra发送和接收JSON
