NginX/Phusion Passenger サーバーで Ruby Net::HTTP を使用して、JSON 文字列をサーバーに POST しようとしています。私のPOSTは、「application/json」として送信する場合にのみ、サーバーへのセッションを時期尚早に閉じているようです。いいえ:

サーバー側:

127.0.0.1 - - [03/Sep/2013 07:47:14] "POST /path/to/submit " 200 45 0.0013
pid=12893 thr=47197563169088 file=ext/nginx/HelperAgent.cpp:933 time=2013-09-03 07:47:14.830 ]: Uncaught exception in PassengerServer client thread:
exception: Cannot read response from backend process: Connection reset by peer (104)

クライアント側のデバッグ セッションは次のとおりです。

データを送信するために使用しているコードは次のとおりです。

private
def _http_client(method = 'get', location = nil, limit = 10) 
    raise ArgumentError, 'FATAL: too many HTTP redirects attempted...' if limit == 0
    response = nil 

    if location.nil?
        if @uri.nil?
            raise ArgumentError 'FATAL: no location specified. Quitting.'
        end 
    else
        @uri = URI.parse(location)
    end 

    client = Net::HTTP.new(@uri.host,@uri.port)
    client.open_timeout    = 15 # in seconds
    client.read_timeout    = 15 # in seconds
    initheader             = {'content-type' => 'application/json',
                              'accept'       => 'application/json',
                              'user-agent'   => UA                ,}
    client.set_debug_output $stderr  # XXX TEMPORARY

    if @uri.scheme == 'https'
        client.use_ssl = true
        client.verify_mode = 0 
    end 

    if method == 'post'
        serialized = JSON.generate(@payload)
        response   = client.send_request('POST',@uri.path,serialized,initheader = initheader)
        puts serialized
    end 

# Only intended for pings. In order to do
# full GETs (including query_params) this
# will need to be refactored a little.
    if method == 'get'
        response = client.get(@uri.path)
    end 

    case response
        when Net::HTTPSuccess
            @status = true
        when Net::HTTPMovedPermanently
            @status = false
            limit = limit - 1 
            _http_client(method,response['location'],limit)
        when Net::HTTPClientError
            $stderr.puts 'Client error.'
            @status = false
        when Net::HTTPServerError

            @status = false
        else
            $stderr.puts 'No idea what the server returned.'
            @status = false
    end 

    unless response.nil?
        @response  = {:code => response.code, :body => (response.body || 'OK')}
        @code      = @response[:code].to_s
        @http_body = @response[:body].to_s
    else
        $stderr.puts 'response from server was empty. :('
    end 

    _send_status
end

私は使用しています：

  • ルビーのバージョン: 1.9.3p448
  • NginX 1.2.6
  • 乗客 3.0.17

私は何か間違ったことをしている可能性があると確信していますが、私はRubyが初めてで、この種のWebプログラミングはほぼ初めてです。

上記のコード スニペットでは メソッドを使用していますが、 、 、send_requestも試しましたが、同じ結果になりました。postpost2

initheader「application/json」を使用するとすぐにすべてが壊れるのでは、本当に疑わしいです。削除すると、すべて正常に動作します。
