System.Net.Http.HttpRequestException: An error occurred while sending the 
request ---> System.Net.WebException: Error: SecureChannelFailure (The   
authentication or decryption has Failed.) ---> System.IO.IOException: The 
authentication or decryption has Failed. ---> System.IO.IOException: The 
authentication or decryption has Failed. ---> 
Mono.Security.Protocol.Tls.TlsException: The authentication or decryption has Failed.

我的代码如下;

public async Task<List<T>> GetList<T>(string url)
    {
        HttpClient client = new HttpClient();
        var response = await client.GetAsync(new Uri(url));
        response.EnsureSuccessStatusCode();
        var content = await response.Content.ReadAsStringAsync();
        return JsonConvert.DeserializeObject<List<T>>(content);
    }

android中的MainClass调用核心类,它调用此服务类.

当API不使用HTTPS时,HttpClient请求会起作用,但每当我使用启用了HTTPS的API时,都会抛出此错误.

我也使用可移植类库来存储代码,因此无法使用HttpWebRequest进行Web请求.

我也尝试过;

ServicePointManager.ServerCertificateValidationCallback += (o,certificate,chain,errors) => true;

和;

System.Security.Cryptography.AesCryptoServiceProvider b = new System.Security.Cryptography.AesCryptoServiceProvider();

在我的应用程序OnCreate类(android)中.

我还将HttpClient实现更改为AndroidClientHandler,同时将SSL / TLS实现更改为1.1.在模拟器和设备上尝试此操作.

有人有建议吗？
