无法通过RestSharp.NetCore进行GET请求

Question

我正在尝试使用RestSharpe.NetCore（v.105.2.3.0）发出GET请求，例如C＃中的https://pokeapi.co/api/v2/pokemon/ditto。

但是，下面的代码出现Error: SecureChannelFailure (Unable to read data from the transport connection: Connection reset by peer.)错误。

IRestClient _client;

protected override async void OnCreate(Bundle bundle)
{
    ...
    var baseurl = "https://pokeapi.co/api/v2/pokemon/";
    var apiMethod = "ditto";
    var request = new RestRequest(apiMethod, Method.GET);

    this._client = new RestClient();
    this._client.BaseUrl = new Uri(baseurl);
    TaskCompletionSource<IRestResponse> taskCompletion = new TaskCompletionSource<IRestResponse>();
    var json = this._client.ExecuteAsync<object>(request, r => taskCompletion.SetResult(r));
    var response = (object)(await taskCompletion.Task);
}

任何想法为何以及如何解决此问题？

Answer 1

在进行连接以使用TLS1.1或1.2连接到站点之前，添加此行。

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

对于代理，将代理添加到客户端

client.Proxy = new WebProxy("127.0.0.1", 8888);
