vb.net - 使用 VB.NET 检索 API JSON (https)(错误 : Canceled the request: Unable to create a secure SSL/TLS channel)

Question

我正在尝试从我的 vb.net 代码查询 API，但在执行“GetResponse”时出现错误“取消请求:无法创建安全的 SSL/TLS channel ”

我已经修改了代码的很多东西试图解决我的问题但是没有任何效果......

我附上代码，我必须看看是否有人可以修复它

    Dim request As HttpWebRequest = HttpWebRequest.Create("https://api.flightstats.com/flex/schedules/rest/v1/json/flight/AA/1917/departing/2018/11/19?appId=583f892b&appKey=e960901ec7dcb40321306743b7a364d0")
    request.Proxy = Nothing
    request.UserAgent = "Test"

    ServicePointManager.ServerCertificateValidationCallback = AddressOf AcceptAllCertifications

    Dim response As HttpWebResponse = request.GetResponse
    Dim response_stream As System.IO.Stream = response.GetResponseStream

    Dim stream_reader As New System.IO.StreamReader(response_stream)
    Dim Data As String = stream_reader.ReadToEnd
    stream_reader.Close()

    MsgBox(Data)

_

Public Function AcceptAllCertifications(ByVal sender As Object, ByVal certification As System.Security.Cryptography.X509Certificates.X509Certificate, ByVal chain As System.Security.Cryptography.X509Certificates.X509Chain, ByVal sslPolicyErrors As System.Net.Security.SslPolicyErrors) As Boolean
    Return True
End Function

代码中有我要查询的api地址
