我想使用經典ASP的這個例子,但我有2頁,一個是表單頁面,另一個是驗證頁面。我是傳統ASP中的全新版本,所以我不確定我是否犯了一些語法錯誤。與經典ASP使用reCAPTCHA
https://developers.google.com/recaptcha/docs/asp
在我的表單頁面,我通過JS加載的reCAPTCHA和部分工作正常。在驗證頁面上,我有下面的代碼。
主代碼(我刪除的東西,從谷歌,我是不會使用像生成與ASP一個驗證碼錶單字段)
recaptcha_challenge_field = Request.Form("recaptcha_challenge_field")
recaptcha_response_field = Request.Form("recaptcha_response_field")
recaptcha_public_key = "hidden" //your public key
recaptcha_private_key = "hidden" //your private key
// returns "" if correct, otherwise it returns the error response
function recaptcha_confirm(rechallenge,reresponse)
Dim VarString
VarString = _
"privatekey=" & recaptcha_private_key & _
"&remoteip=" & Request.ServerVariables("REMOTE_ADDR") & _
"&challenge=" & rechallenge & _
"&response=" & reresponse
Dim objXmlHttp
Set objXmlHttp = Server.CreateObject("Msxml2.ServerXMLHTTP")
objXmlHttp.open "POST", "http://www.google.com/recaptcha/api/verify", False
objXmlHttp.setRequestHeader "Content-Type", "application/x-www-form-urlencoded"
objXmlHttp.send VarString
Dim ResponseString
ResponseString = split(objXmlHttp.responseText, vblf)
Set objXmlHttp = Nothing
if ResponseString(0) = "true" then
'They answered correctly
recaptcha_confirm = ""
else
'They answered incorrectly
recaptcha_confirm = ResponseString(1)
end if
end function
server_response = ""
newCaptcha = True
if (recaptcha_challenge_field <> "" or recaptcha_response_field <> "") then
server_response = recaptcha_confirm(recaptcha_challenge_field, recaptcha_response_field)
newCaptcha = False
end if
這就是我想要檢測是否驗證碼是正確的,但它以任何方式提交表格。
if recaptcha_response_field <> "" AND newCaptcha = False then
// submit form
Else
Response.Write "Error: Please fill out all form fields correctly."
End If
沒有你查詢Server_response變量,而不是recaptcha_response_field變量?因爲recaptcha_response_field與request.form參數匹配,當然是<>「」,因爲用戶輸入了一個值? – ulluoink
我試過,但仍然允許表單提交。 – zen
