當我嘗試發送HTTP請求時，出現application error Errno::ECONNREFUSED錯誤。我正在使用Sinatra，並將其設置在本地工作站上。以下是錯誤：應用程序錯誤Errno :: ECONNREFUSED在Ruby中

這裏是我的sendGetRequest：
def sendGetRequest(url, mMethod, key, rHash, headers, publicToken)
mKey = String.new(key)
nMethod =String.new(mMethod)
nKey = mKey.concat(nMethod)
uri = URI.parse(URI.encode(url))
http = Net::HTTP.new(uri.host, uri.port)
request = Net::HTTP::Get.new(uri.request_uri)
headers.each do |hKey, hVal|
request[hKey] = hVal
end
request["Authorization"] = publicToken
if uri.scheme == "https"
http.use_ssl = true
http.verify_mode = OpenSSL::SSL::VERIFY_NONE
response = http.request(request)
else
response = http.request(request)
response.body
#response = Net::HTTP.get_response(uri)
end
if response.code == '200'
code = response.code
puts "#{mMethod}: - Test passed! Response code: #{response.code}"
rHash[nKey] = code
#puts "#{rHash}"
else
code = response.code
puts "#{mMethod}: - Test failed! Response code: #{response.code}"
rHash[nKey] = code
#puts "#{rHash}"
end
return rHash
end
我不知道我在做什麼錯得到這個錯誤。如果任何人都可以提供幫助，那會很棒。如果您需要更多代碼，請讓我知道。
是什麼'uri.host'和'uri.port'？ – Thomas
我正在傳遞一個'URL'，它是：'www.myurl.more.com/service/something?expand=something（。（this））＆that = something'。我假設'URI = URI.parse（URI.encode（url））'函數解析出來。我想我可以記錄下來，看看裏面究竟有什麼？ – BlackHatSamurai
'uri.host' = myurl.more.com＆'uri.port' = 80 – BlackHatSamurai
