验证码2.0验证失败 [英] Recaptcha 2.0 validation failed
问题描述
我现在面临问题的Recaptcha 2.0。其工作罚款，直到我按一下按钮，检查验证。但它总是执行else块并显示验证失败。我失去了something.Please帮助。
在ASPX，
＆LT;头=服务器＆GT;
＆LT;标题＆GT;＆LT; /标题＆GT;
＆LT;脚本类型=文/ JavaScript的SRC =https://www.google.com/recaptcha/api.js＆GT;＆LT; / SCRIPT＆GT;
＆LT; /头＆GT;
＆LT;身体GT;
＆LT;？的形式ID =form1的行动=方法=邮报=服务器＆GT;
＆LT; DIV＆GT;
＆LT; DIV CLASS =G-验证码数据sitekey =PUBLIC_KEY＆GT;＆LT; / DIV＆GT;
＆LT; ASP：按钮的ID =ButtonCheck=服务器文本=检查的OnClick =ButtonCheck_Click/＆GT;
＆LT; ASP：标签ID =LabelMessage=服务器＆GT;＆LT; / ASP：标签＆gt;
＆LT; / DIV＆GT;
＆LT; /表及GT;
＆LT; /身体GT;
然后，班组长，
公共类为MyObject
{
公共字符串成功{搞定;组; }
}
然后code文件的背后，
保护无效的Page_Load（对象发件人，EventArgs的发送）
{ } 保护无效ButtonCheck_Click（对象发件人，EventArgs的发送）
{
如果（Page.IsValid）
{
如果（CheckValidation（））
{
LabelMessage.Text =你准备好了。
}
其他
{
LabelMessage.Text =验证失败。
}
}
}
公共BOOL CheckValidation（）
{
字符串的响应=请求[G-验证码响应];
布尔有效= FALSE;
HttpWebRequest的要求= (HttpWebRequest)WebRequest.Create(\"https://www.google.com/recaptcha/api/siteverify?secret=Private_Key ＆放大器;响应=+响应）;
尝试
{
使用（WebResponse类WebResponse类= request.GetResponse（））
{
使用（StreamReader的StreamReader的=新的StreamReader（webResponse.GetResponseStream（）））
{
字符串jasonResponse = streamReader.ReadToEnd（）;
JS的JavaScriptSerializer =新的JavaScriptSerializer（）;
为MyObject数据= js.Deserialize＆LT;＆MyObject的GT;（jasonResponse）;
有效值= Convert.ToBoolean（data.success）;
}
}
返回有效的;
}
赶上（引发WebException前）

I am facing problem with Recaptcha 2.0. Its working fine untill I click the button to check for validation. But it always executing the else block and showing "Validation failed.".Am I missing something.Please Help.
In aspx,
<head runat="server">
<title></title>
<script type="text/javascript" src="https://www.google.com/recaptcha/api.js"></script>
</head>
<body>
<form id="form1" action="?" method="post" runat="server">
<div>
<div class="g-recaptcha" data-sitekey="Public_Key"></div>
<asp:Button ID="ButtonCheck" runat="server" Text="Check" OnClick="ButtonCheck_Click" />
<asp:Label ID="LabelMessage" runat="server" ></asp:Label>
</div>
</form>
</body>
Then a classs,
public class MyObject
{
public string success { get; set; }
}
Then In Code Behind File,
protected void Page_Load(object sender, EventArgs e)
{
}
protected void ButtonCheck_Click(object sender, EventArgs e)
{
if(Page.IsValid)
{
if(CheckValidation())
{
LabelMessage.Text = "You are ready to go.";
}
else
{
LabelMessage.Text = "Validation Failed.";
}
}
}
public bool CheckValidation()
{
string Response = Request["g-recaptcha-response"];
bool Valid = false;
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://www.google.com/recaptcha/api/siteverify?secret=Private_Key &response=" + Response);
try
{
using(WebResponse webResponse=request.GetResponse())
{
using(StreamReader streamReader=new StreamReader(webResponse.GetResponseStream()))
{
string jasonResponse = streamReader.ReadToEnd();
JavaScriptSerializer js = new JavaScriptSerializer();
MyObject data = js.Deserialize<MyObject>(jasonResponse);
Valid = Convert.ToBoolean(data.success);
}
}
return Valid;
}
catch(WebException ex)
{
throw ex;
}
}
There is another way to display Google Recaptcha on your WebForm by adding Reference to reCaptcha DLL into asp .net application.
Get your recaptcha keys from here.
Step 1: Download reCaptcha DLL. You can download latest reCaptcha DLL from this link.
Step 2: Unzip the archived folder. After unzipping the archived folder you will see following files.
Step 3: Add refrence to reCaptcha DLL.
Browse Recaptcha DLL
Select DLL File
Step 4: Register reCaptcha to asp .net webpage by adding Tagprefix.
<%@ Register TagPrefix="recaptcha" Namespace="Recaptcha" Assembly="Recaptcha" %>
Step 5: Add reCaptcha Code into webpage
<asp:label id="lblResult" runat="server"></asp:label>
<recaptcha:recaptchacontrol id="RecaptchaControl2" runat="server" publickey="Paste-Your-Public-Kye-here" privatekey="Pase-Your-Private-Key-Here" theme="blackglass"></recaptcha:recaptchacontrol>
<asp:button id="btnSubmit" runat="server" text="Submit" onclick="btnSubmit_Click"></asp:button>
Code Behind:
protected void btnSubmit_Click(object sender, EventArgs e)
{
if (RecaptchaControl2.IsValid)
{
lblResult.Text = "You Got It!";
lblResult.ForeColor = Color.Green;
}
else
{
lblResult.Text = "Incorrect";
lblResult.ForeColor = Color.Red;
}
}
