问题描述
我已经使用 System.Windows.Controls.Webbrowser 验证接收Facebook的OAuth的响应字符串时，遇到了一个奇怪的问题。继请求URI发送：
但我收到的仅仅 https://www.facebook.com/connect/login_success.html ，即没有的access_token。
奇怪的是，复制和放大器;请求URI粘贴到浏览器（例如，IE8）正确返回AUTH-URI
<$p$p><$c$c>https://www.facebook.com/connect/login_success.html#access_token=[PROPERTOKEN]&expires_in=[PROPERNUMBER]这就是我一直在努力：（全C＃类： http://pastebin.com/GePLHXnD ）
首先，发送请求URI：
私人无效Window_Loaded（对象发件人，RoutedEventArgs E）
{
StringBuilder的authReqUri =新的StringBuilder（https://www.facebook.com/dialog/oauth?client_id=）;
authReqUri.Append（Properties.Settings.Default.FBAppID）;
authReqUri.Append（与＆amp; REDIRECT_URI = HTTPS：//www.facebook.com/connect/login_success.html&范围=）;
authReqUri.Append（Properties.Settings.Default.FBScope）;
authReqUri.Append（与＆amp; RESPONSE_TYPE =令牌）;
Properties.Settings.Default.FBReqString = authReqUri.ToString（）;
返回;
}
和onWindowClose执行解析令牌：
///＆LT;总结＆gt;
///属性，以指示与Facebook的身份验证是成功的
///＆LT; /总结＆gt;
公共BOOL AuthenticatedSuccessfully
{
得到
{
//强制转换为浏览器控件得到的电流源
如果（uiFrameLogin.Content.GetType（）== typeof运算（web浏览器））
{
web浏览器网页浏览器=（web浏览器）uiFrameLogin.Content;
如果（webBrowser.Source = NULL＆放大器;！＆安培; webBrowser.Source.ToString（）包含（与＆amp;错误））
返回false; //寻找一个错误
其他
如果（
webBrowser.Source = NULL＆放大器;！＆安培;
webBrowser.Source.AbsolutePath.Contains（login_success）
）
{
串温度;
临时= Regex.Replace（webBrowser.Source.Fragment，^ *的access_token =，）;
Properties.Settings.Default.FBAccessToken = System.Text.RegularEx pressions.Regex.Replace（温度，与＆amp; *，）; 临时= Regex.Replace（webBrowser.Source.Fragment。^ *的access_token = *＆放大器;，）;
Properties.Settings.Default.FBExpiresIn = System.Text.RegularEx pressions.Regex.Replace（温度，expires_in =，）; 返回true; //如果在这个页面，我们已经成功地auth'd
}
} 返回false; //无法找到的成功页面，预示着一个成功的权威性 - 没有返回FALSE。
}
}
解决方案
这code工程....
私人无效的button1_Click（对象发件人，EventArgs的发送）
{
webBrowser1.Navigated + =新WebBrowserNavigatedEventHandler（webBrowser1_Navigated）;
webBrowser1.Navigate(\"https://www.facebook.com/dialog/oauth?client_id=[AppId]&redirect_uri=https://www.facebook.com/connect/login_success.html&scope=publish_stream,read_friendlists,email&response_type=token\");
}无效webBrowser1_Navigated（对象发件人，WebBrowserNavigatedEventArgs E）
{
Console.WriteLine（webBrowser1.Url）;
}
I've been encountering a weird problem when receiving the Facebook oauth response string using System.Windows.Controls.Webbrowser for authentication. Following request URI is sent:
https://www.facebook.com/dialog/oauth?client_id=[APPID]&redirect_uri=https://www.facebook.com/connect/login_success.html&scope=publish_stream,read_friendlists,email&response_type=token
but what I receive is only https://www.facebook.com/connect/login_success.html, i.e. no access_token.
Strangely, copy&paste the request URI into a browser (e.g. IE8) properly returns the auth-uri
https://www.facebook.com/connect/login_success.html#access_token=[PROPERTOKEN]&expires_in=[PROPERNUMBER]
Here's what I've been trying: (Full C# class: http://pastebin.com/GePLHXnD )
First, send the request URI:
private void Window_Loaded(object sender, RoutedEventArgs e)
{
StringBuilder authReqUri = new StringBuilder("https://www.facebook.com/dialog/oauth?client_id=");
authReqUri.Append(Properties.Settings.Default.FBAppID);
authReqUri.Append( "&redirect_uri=https://www.facebook.com/connect/login_success.html&scope=");
authReqUri.Append(Properties.Settings.Default.FBScope);
authReqUri.Append("&response_type=token");
Properties.Settings.Default.FBReqString = authReqUri.ToString();
return;
}
And onWindowClose execute parsing the token:
/// <summary>
/// Property to indicate if authentication with facebook was a success
/// </summary>
public bool AuthenticatedSuccessfully
{
get
{
// Cast to a browser control to get at the current source
if (uiFrameLogin.Content.GetType() == typeof(WebBrowser))
{
WebBrowser webBrowser = (WebBrowser)uiFrameLogin.Content;
if (webBrowser.Source != null && webBrowser.Source.ToString().Contains("&error"))
return false; // look for an error
else
if (
webBrowser.Source != null &&
webBrowser.Source.AbsolutePath.Contains("login_success")
)
{
string temp;
temp = Regex.Replace(webBrowser.Source.Fragment, "^.*access_token=", "");
Properties.Settings.Default.FBAccessToken = System.Text.RegularExpressions.Regex.Replace(temp, "&.*", "");
temp = Regex.Replace(webBrowser.Source.Fragment, "^.*access_token=.*&", "");
Properties.Settings.Default.FBExpiresIn = System.Text.RegularExpressions.Regex.Replace(temp, "expires_in=", "");
return true; // if its at this page, we've auth'd successfully
}
}
return false; // cant find the success page, cant indicate a successful auth - no return false.
}
}
解决方案
This code works....
private void button1_Click(object sender, EventArgs e)
{
webBrowser1.Navigated += new WebBrowserNavigatedEventHandler(webBrowser1_Navigated);
webBrowser1.Navigate("https://www.facebook.com/dialog/oauth?client_id=[AppId]&redirect_uri=https://www.facebook.com/connect/login_success.html&scope=publish_stream,read_friendlists,email&response_type=token");
}
void webBrowser1_Navigated(object sender, WebBrowserNavigatedEventArgs e)
{
Console.WriteLine(webBrowser1.Url);
}
