使用VB.NET檢索API JSON（https）（錯誤：取消了請求：無法創建安全的SSL / TLS通道）

Question

我正在嘗試從vb.net代碼中查詢API，但是在執行“ GetResponse”時出現錯誤“ 已取消請求：無法創建安全的SSL / TLS通道 ”

我已經修改了代碼的許多內容，試圖解決我的問題，但是沒有任何效果...

我附上我必須看的代碼，看是否有人可以修復它

    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

在代碼中，您具有我想查詢的api地址

在您的請求之前添加此：

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12
