Ste*_*eve 5 vb.net asp.net recaptcha
我试图让新的Google reCaptcha在我的ASP.NET项目中工作,我遇到了问题,让它成为新的"我不是机器人".
我在那里有旧的,在对developers.google.com网站进行了大量研究后,一切看起来都一样(他们甚至指向我下载相同的dll - 1.0.5).所以,我得到了新的密钥并将它们放入并且它可以工作,但它看起来就像旧的reCaptcha.
有没有人得到新的ASP.Net工作？我错过了什么？
编辑:
因此,在测试应用程序中搜索并搜索其他一些网站,我发现如果我创建这样的页面:
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>reCAPTCHA demo: Simple page</title>
<script src="https://www.google.com/recaptcha/api.js" async defer></script>
</head>
<body>
<form id="form1" runat="server" action="?" method="POST">
<div>
<div class="g-recaptcha" data-sitekey="My Public Key"></div>
<br/>
<asp:Button ID="Button1" runat="server" Text="Submit" />
</div>
</form>
</body>
</html>
然后在我的代码隐藏(Button1_Click)中,我这样做:
Dim Success As Boolean
Dim recaptchaResponse As String = request.Form("g-recaptcha-response")
If Not String.IsNullOrEmpty(recaptchaResponse) Then
Success = True
Else
Success = False
End If
该recaptchaResponse要么是空的或填充取决于他们是否是僵尸或没有.问题是,我现在需要把这个回复用私钥发送给google,这样我就可以验证响应是不是由机器人提供的,在我的代码隐藏中,但我无法弄清楚如何.我试过这个(取代Success = True):
Dim client As New System.Net.Http.HttpClient()
client.BaseAddress = New Uri("https://www.google.com/recaptcha/")
client.DefaultRequestHeaders.Accept.Clear()
client.DefaultRequestHeaders.Accept.Add(New Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json"))
Dim response As Net.Http.HttpResponseMessage = Await client.GetAsync("api/siteverify?secret=My Private key&response=" + recaptchaResponse)
If (response.IsSuccessStatusCode) Then
Dim CaptchResponse As ReCaptchaModel = Await response.Content.ReadAsAsync(Of ReCaptchaModel)()
Success = CaptchResponse.success
Else
Success = False
End If
但是,我无法弄清楚如何让异步的东西工作,我找不到什么是什么ReCaptchaModel,所以我找到另一种方法来调用Web服务并得到一个json响应并尝试这样做:
Dim request As Net.WebRequest = Net.WebRequest.Create("https://www.google.com/recaptcha/")
Dim Data As String = "api/siteverify?secret=My Private Key&response=" + recaptchaResponse
request.Method = "POST"
request.ContentType = "application/json; charset=utf-8"
Dim postData As String = "{""data"":""" + Data + """}"
'get a reference to the request-stream, and write the postData to it
Using s As IO.Stream = request.GetRequestStream()
Using sw As New IO.StreamWriter(s)
sw.Write(postData)
End Using
End Using
'get response-stream, and use a streamReader to read the content
Using s As IO.Stream = request.GetResponse().GetResponseStream()
Using sr As New IO.StreamReader(s)
'decode jsonData with javascript serializer
Dim jsonData = sr.ReadToEnd()
Stop
End Using
End Using
但是,这只是通过https://www.google.com/recaptcha向我提供了该网页的内容.不是我想要的.在谷歌网页是不是非常有用,我被困在哪里去了.我需要一些帮助,要么调用Google验证服务,要么是否有人从ASP.NET找到了另一种方法.
当我碰到一些不相关的东西时,我只是放弃了,这让我再次以不同的方式思考它.在我上面的最后一次尝试中,我试图将私钥和recaptcha响应作为数据传递,所以我create在WebRequest中尝试了它并且它有效.这是最终的解决方案:
使用上面发布的相同的HTML,我创建了一个函数,我可以在按钮单击事件中调用,我检查Page.IsValid并调用此函数:
Private Function IsGoogleCaptchaValid() As Boolean
Try
Dim recaptchaResponse As String = Request.Form("g-recaptcha-response")
If Not String.IsNullOrEmpty(recaptchaResponse) Then
Dim request As Net.WebRequest = Net.WebRequest.Create("https://www.google.com/recaptcha/api/siteverify?secret=My Private Key&response=" + recaptchaResponse)
request.Method = "POST"
request.ContentType = "application/json; charset=utf-8"
Dim postData As String = ""
'get a reference to the request-stream, and write the postData to it
Using s As IO.Stream = request.GetRequestStream()
Using sw As New IO.StreamWriter(s)
sw.Write(postData)
End Using
End Using
''get response-stream, and use a streamReader to read the content
Using s As IO.Stream = request.GetResponse().GetResponseStream()
Using sr As New IO.StreamReader(s)
'decode jsonData with javascript serializer
Dim jsonData = sr.ReadToEnd()
If jsonData = "{" & vbLf & " ""success"": true" & vbLf & "}" Then
Return True
End If
End Using
End Using
End If
Catch ex As Exception
'Dont show the error
End Try
Return False
End Function
我确信代码有所改进,但它确实有效.我看不到添加一些JSON库的引用来读取一个我只检查字符串的东西.
