HTTPS发布失败 [英] HTTPS Post failure

问题描述

我正在尝试向我的Xamarin Forms应用程序上的API发送POST请求，但收到一条错误消息，指示发送请求时不存在信任关系.我不知道这是为什么以及如何解决.例外:

I´m trying to send a POST request to an API on my Xamarin Forms application and I´m getting an error that indicates that there is no trust relationship when sending the request. I cannot find out why is this and how to solve it. This is the exception:

System.Net.Http.HttpRequestException:发送时发生错误 请求---> System.Net.WebException:错误:TrustFailure(The 身份验证或解密失败.)---> System.IO.IOException: 身份验证或解密失败. ---> System.IO.IOException:身份验证或解密失败. ---> Mono.Security.Protocol.Tls.TlsException:从服务器接收到无效的证书.错误代码:0xffffffff800b010f，位于 Mono.Security.Protocol.Tls.RecordProtocol.EndReceiveRecord (System.IAsyncResult asyncResult)[0x00031]在 /Users/builder/jenkins/workspace/xamarin-android/xamarin-android/external/mono/mcs/class/Mono.Security/Mono.Security.Protocol.Tls/RecordProtocol.cs:430 在Mono.Security.Protocol.Tls.SslClientStream.SafeEndReceiveRecord (System.IAsyncResult ar，System.Boolean ignoreEmpty)在[0x00000]中 /Users/builder/jenkins/workspace/xamarin-android/xamarin-android/external/mono/mcs/class/Mono.Security/Mono.Security.Protocol.Tls/SslClientStream.cs:256 在Mono.Security.Protocol.Tls.SslClientStream.NegotiateAsyncWorker (System.IAsyncResult结果)在[0x00071]中 /Users/builder/jenkins/workspace/xamarin-android/xamarin-android/external/mono/mcs/class/Mono.Security/Mono.Security.Protocol.Tls/SslClientStream.cs:418 ---内部异常堆栈跟踪的结尾---

导致此异常的代码如下:

The code resulting in this exception is the following:

MultipartFormDataContent content = new MultipartFormDataContent();
content.Headers.Add("X-Auth-Token", "eb27c17f-8bd6-4b94-bc4f-742e361b4e6a");
content.Headers.ContentType = MediaTypeHeaderValue.Parse("image/jpeg");

content.Add(new ByteArrayContent(myByteImage));

try
{
    HttpResponseMessage response = await _client.PostAsync("https://10.54.66.160:9000/3/matching/search?list_id=3c9f2623-28be-435f-a49f-4dc29c186809&limit=1", content);

    string responseContent = await response.Content.ReadAsStringAsync();
}
catch (Exception ex)
{
    throw;
}

推荐答案

看来，问题解决了，将以下代码放在MainActivity.cs

It seems the problem solved putting the following code on MainActivity.cs

System.Net.ServicePointManager.ServerCertificateValidationCallback +=
            (sender, cert, chain, sslPolicyErrors) =>
            {
                if (cert != null) System.Diagnostics.Debug.WriteLine(cert);
                return true;
            };

如@ DanielA.White似乎HttpClient的mono实现不支持自签名证书.

As @DanielA.White It seems that the mono implementation of HttpClient does not support self signed certificates.
