我的客户已经通知我的问题与他们的SSL和Internet Explorer。 他们说，在访问URL时，他们得到的信任问题。

我通过HTTPS访问JSON。 该网站位于一个服务器上，我用我的本地机器上的控制台应用程序。 我试图绕过SSL证书，但是，我的代码仍然失败。

我可以改变的HttpWebRequest来解决这个问题？

我得到使用此代码此错误： 

    // You must change the URL to point to your Web server.
        HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
        req.Method = "GET";
        req.AllowAutoRedirect = true;

        // allows for validation of SSL conversations
        ServicePointManager.ServerCertificateValidationCallback = delegate { return true; };


        WebResponse respon = req.GetResponse();
        Stream res = respon.GetResponseStream();

        string ret = "";
        byte[] buffer = new byte[1048];
        int read = 0;
        while ((read = res.Read(buffer, 0, buffer.Length)) > 0)
        {
            //Console.Write(Encoding.ASCII.GetString(buffer, 0, read));
            ret += Encoding.ASCII.GetString(buffer, 0, read);
        }
        return ret;

Answer 1:

我不得不启用其它安全协议版本来解决此问题： 

    ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls
        | SecurityProtocolType.Tls11
        | SecurityProtocolType.Tls12
        | SecurityProtocolType.Ssl3;


Answer 2:

我启用了使用此代码登录：

http://blogs.msdn.com/b/dgorti/archive/2005/09/18/471003.aspx

该日志是在bin / debug文件夹（我是在调试模式下为我的控制台应用程序）。 您需要添加的安全协议类型，SSL 3

我在日志中收到的算法不匹配。 这是我的新的代码： 

        // You must change the URL to point to your Web server.
        HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
        req.Method = "GET";
        ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3;


        // Skip validation of SSL/TLS certificate
        ServicePointManager.ServerCertificateValidationCallback = delegate { return true; };


        WebResponse respon = req.GetResponse();
        Stream res = respon.GetResponseStream();

        string ret = "";
        byte[] buffer = new byte[1048];
        int read = 0;
        while ((read = res.Read(buffer, 0, buffer.Length)) > 0)
        {
            Console.Write(Encoding.ASCII.GetString(buffer, 0, read));
            ret += Encoding.ASCII.GetString(buffer, 0, read);
        }
        return ret;


Answer 3:

类似于现有的答案 ，但在PowerShell中： 

[System.Net.ServicePointManager]::SecurityProtocol = `
[System.Net.SecurityProtocolType]::Tls11 -bor 
[System.Net.SecurityProtocolType]::Tls12 -bor `   
[System.Net.SecurityProtocolType]::Tls -bor `
[System.Net.SecurityProtocolType]::Ssl3

然后调用调用-的WebRequest应该工作。

匿名反馈得到这个，很好的建议：更简单的方式来写，这将是： 

[System.Net.ServicePointManager]::SecurityProtocol = @("Tls12","Tls11","Tls","Ssl3")

通过Jaykul发现这个奇妙和相关岗位： 验证自签名证书从.net和PowerShell



Answer 4:

这可能是由一些事情引起的（最有可能最有可能）：

  1. 该服务器的SSL证书是由客户端不可信。 最简单的检查是在URL指向一个浏览器，看看如果你得到一个SSL锁图标。 如果你得到一个锁坏了，图标，点击它，看看是什么问题：

    1. 过期日期 - 得到一个新的SSL证书
    2. 名称不匹配 - 请确保您的网址使用相同的服务器名称作为证书。
    3. 由受信任的权威没有签署 - 买从权威机构的证书（例如Verisign），或者证书添加到客户端的受信任的证书存储区。
    4. 在测试环境中，您可以更新您的证书验证跳过访问检查。 不要在生产中做到这一点。

  2. 服务器需要客户端SSL证书 - 在这种情况下，你将不得不更新你的代码签署与客户端证书的请求。



Answer 5:

请参阅一旦跌破链接。 SecurityProtocolType.SsL3是现在老了。

Answer 6:

我发现证书的类型也开始发挥作用。

我有一个证书，这是：

（下面的输出是在MMC中，证书属性）

数字签名，密钥加密（A0）

（下面的输出是从我的C＃代码下文）

X509Extension.X509KeyUsageExtension.KeyUsages = 'KeyEncipherment，的DigitalSignature' X509KeyUsageExtension.KeyUsages.X509KeyUsageFlags.CrlSign = 'FALSE' X509KeyUsageExtension.KeyUsages.X509KeyUsageFlags.DataEncipherment = 'FALSE' X509KeyUsageExtension.KeyUsages.X509KeyUsageFlags.DecipherOnly = 'FALSE' X509KeyUsageExtension.KeyUsages.X509KeyUsageFlags。的DigitalSignature = ' 真 'X509KeyUsageExtension.KeyUsages.X509KeyUsageFlags.EncipherOnly =' FALSE' X509KeyUsageExtension.KeyUsages.X509KeyUsageFlags.KeyAgreement = 'FALSE' X509KeyUsageExtension.KeyUsages.X509KeyUsageFlags.KeyCertSign = 'FALSE' X509KeyUsageExtension.KeyUsages.X509KeyUsageFlags.KeyEncipherment = ' 真 ' X509KeyUsageExtension .KeyUsages.X509KeyUsageFlags.None = '假' X509KeyUsageExtension.KeyUsages.X509KeyUsageFlags.NonRepudiation = '假'

以上没有工作。

===============================

然后另一个证书有：

（下面的输出是在MMC中，证书属性）

证书签名，脱机CRL签名，CRL签名（06）

（下面的输出是从我的C＃代码下文）

X509Extension.X509KeyUsageExtension.KeyUsages = 'CrlSign，KeyCertSign' X509KeyUsageExtension.KeyUsages.X509KeyUsageFlags.CrlSign = ' 真 'X509KeyUsageExtension.KeyUsages.X509KeyUsageFlags.DataEncipherment =' FALSE' X509KeyUsageExtension.KeyUsages.X509KeyUsageFlags.DecipherOnly = 'FALSE' X509KeyUsageExtension.KeyUsages.X509KeyUsageFlags。的DigitalSignature = '假' X509KeyUsageExtension.KeyUsages.X509KeyUsageFlags.EncipherOnly = 'FALSE' X509KeyUsageExtension.KeyUsages.X509KeyUsageFlags.KeyAgreement = 'FALSE' X509KeyUsageExtension.KeyUsages.X509KeyUsageFlags.KeyCertSign = ' 真 'X509KeyUsageExtension.KeyUsages.X509KeyUsageFlags.KeyEncipherment =' FALSE' X509KeyUsageExtension .KeyUsages.X509KeyUsageFlags.None = '假' X509KeyUsageExtension.KeyUsages.X509KeyUsageFlags.NonRepudiation = '假'

和它的工作
