从服务器xamarin.android收到的证书无效 [英] Invalid certificate received from server xamarin.android

问题描述

所以这让我抓狂了1天了.我正在尝试与xamarin.android上的REST API通讯，但由于某些原因，我收到此错误:

So this is driving me crazy for 1 day now. I'm trying to talk to a REST API on xamarin.android but for some reason I get this error:

InnerException  {Mono.Security.Protocol.Tls.TlsException: Invalid
certificate received from server. Error code: 0xffffffff800b010a   at

Mono.Security.Protocol.Tls.RecordProtocol.InternalReceiveRecordCallback

}   Mono.Security.Protocol.Tls.TlsException

经过一些研究，我发现这与我正在与之交谈的服务器缺少证书有关(如果我错了，请更正我).因此，我在Mac上的钥匙串中添加了SSL证书.我还运行了Mozilla命令以安装默认证书.

After some research I found that this has to do with the missing certificate from the server I'm talking to (correct me if I'm wrong). So I added the SSL certificate to keychain on my Mac. I also ran the Mozilla command for installing the default certificates.

不幸的是，这仍然行不通.在Windows上，与API的连接就像一个超级按钮.据我了解，这是因为Windows拥有自己的CA存储区和一些默认证书.

Unfortunately this still not works. On windows the connection with the API works like a charm. From what I read this is because windows got its own CA store and some default certificates.

推荐答案

我遇到了与您相同的问题，就我而言，我实际上设法确定我的证书名与匹配项不符.我不知道该怎么解决，因为这不是我的服务器，而是我要从中请求数据.

I'm having the same issues as you do, in my case I actually managed to figure out I had a certificatename-missmatch. Something I don't know how to solve, as it's not my server I am requesting data from.

到目前为止，我使用的一种变通方法是压制所有SLL，并使用以下代码接受其中的所有内容:

A work-around for development I used so far is to surpress all SLL, and just accept all there is using the following code:

                ServicePointManager.ServerCertificateValidationCallback = new RemoteCertificateValidationCallback
                (
                    (srvPoint, certificate, chain, errors) => true
                );

或更短

ServicePointManager.ServerCertificateValidationCallback = new RemoteCertificateValidationCallback(delegate { return true; });

但是，请注意，这不是解决问题的方法，而只是一种变通方法，因此您可以继续进行开发.

However, take note that this is not THE solution to the problem, but just a work-around so you can continue developing.

我希望这对您有所帮助，并且您现在就可以意识到这个令人讨厌的异常:-)

I hope this helps you out, and you can get your mind of this nasty exception for now :-)
