我刚刚在我的网站上安装了reCaptcha并将控件放在我的评论帖上,到目前为止一直很好。
现在验证reCaptcha它只是做了Page.IsValid。
然而,BlogEngine使用Ajax和一些JS发布其addComment函数,如果我测试那里,我只是在状态栏中的页面上得到错误。
这是bloengine post函数 -
/// <summary>
/// Processes a callback event that targets a control.
/// </summary>
/// <param name="eventArgument">A string that represents an event argument to pass to the event handler.</param>
public void RaiseCallbackEvent(string eventArgument)
{
if (!BlogSettings.Instance.IsCommentsEnabled)
return;
string[] args = eventArgument.Split(new string[] { "-|-" }, StringSplitOptions.None);
string author = args[0];
string email = args[1];
string website = args[2];
string country = args[3];
string content = args[4];
bool notify = bool.Parse(args[5]);
bool isPreview = bool.Parse(args[6]);
string sentCaptcha = args[7];
//If there is no "reply to" comment, args[8] is empty
Guid replyToCommentID = String.IsNullOrEmpty(args[8]) ? Guid.Empty : new Guid(args[8]);
string storedCaptcha = hfCaptcha.Value;
Comment comment = new Comment();
comment.Id = Guid.NewGuid();
comment.ParentId = replyToCommentID;
comment.Author = Server.HtmlEncode(author);
comment.Email = email;
comment.Content = Server.HtmlEncode(content);
comment.IP = Request.UserHostAddress;
comment.Country = country;
comment.DateCreated = DateTime.Now;
comment.Parent = Post;
comment.IsApproved = !BlogSettings.Instance.EnableCommentsModeration;
if (Page.User.Identity.IsAuthenticated)
comment.IsApproved = true;
if (website.Trim().Length > 0)
{
if (!website.ToLowerInvariant().Contains("://"))
website = "http://" + website;
Uri url;
if (Uri.TryCreate(website, UriKind.Absolute, out url))
comment.Website = url;
}
if (notify && !Post.NotificationEmails.Contains(email))
Post.NotificationEmails.Add(email);
else if (!notify && Post.NotificationEmails.Contains(email))
Post.NotificationEmails.Remove(email);
if (!isPreview)
{
Post.AddComment(comment);
SetCookie(author, email, website, country);
}
string path = Utils.RelativeWebRoot + "themes/" + BlogSettings.Instance.Theme + "/CommentView.ascx";
CommentViewBase control = (CommentViewBase)LoadControl(path);
control.Comment = comment;
control.Post = Post;
using (StringWriter sw = new StringWriter())
{
control.RenderControl(new HtmlTextWriter(sw));
_Callback = sw.ToString();
}
}
我试过把if(!Page.IsValid)放回去;但那从未奏效。

reCaptcha的默认API不适用于AJAX驱动的网页,尤其是当您替换reCaptcha所在的内容时。这里的问题是默认的reCaptcha API。只需切换到AJAX API,也提供here

var captchaChallengeValue = filterContext.HttpContext.Request.Form["recaptcha_challenge_field"];
var captchaResponseValue = filterContext.HttpContext.Request.Form["recaptcha_response_field"];
var captchaValidator = new Recaptcha.RecaptchaValidator
{
PrivateKey = "private key here",
RemoteIP = filterContext.HttpContext.Request.UserHostAddress,
Challenge = captchaChallengeValue,
Response = captchaResponseValue
};
var recaptchaResponse = captchaValidtor.Validate();
这就是我在不同网站上的表现。我接受了输入的内容和响应,然后创建了一个新的captchaValidator,它有一个方法可以检查响应是否有效。然后将其用作if。
的布尔值我正在使用ASP.Net MVC。但是,我认为这个想法是相似的。
希望这有帮助。
