Question

我正在尝试向我的Xamarin Forms应用程序上的API发送POST请求，并且我收到一条错误，指示发送请求时没有信任关系。我不明白为什么会这样，以及如何解决它。这是例外：

System.Net.Http.HttpRequestException：发送时发生错误请求---＆gt; System.Net.WebException：错误：TrustFailure（The 验证或解密失败。）---＆gt; System.IO.IOException：身份验证或解密失败。 ---＆GT; System.IO.IOException：身份验证或解密失败。 ---＆GT; Mono.Security.Protocol.Tls.TlsException：从服务器收到的证书无效。错误代码：0xffffffff800b010f at Mono.Security.Protocol.Tls.RecordProtocol.EndReceiveRecord （System.IAsyncResult asyncResult）[0x00031] in /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）[0x00000] in /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）[0x00071] in /Users/builder/jenkins/workspace/xamarin-android/xamarin-android/external/mono/mcs/class/Mono.Security/Mono.Security.Protocol.Tls/SslClientStream.cs:418 ---内部异常堆栈跟踪结束---

导致此异常的代码如下：

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;
}

似乎问题解决了将以下代码放在MainActivity.cs

上

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

As @ DanielA.White似乎HttpClient的单声道实现不支持自签名证书。
