請求被中止: 未能建立 SSL/TLS 安全通道”的原因及解決辦法

4 個解決辦法，我用的第四個方法就解決了， 登錄檔手動新增的 重啟後不管用，第四個方法 直接用程式改一下方便
首先得保證伺服器是否支援 tls1.2 去登錄檔裡查或者百度怎麼查,基本大多數都用的是1.2
1.
程式碼前加這個
ServicePointManager.Expect100Continue = true; ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls; ServicePointManager.ServerCertificateValidationCallback = (sender, certificate, chain, errors) => true;
或者 ServicePointManager.SecurityProtocol = (SecurityProtocolType)192 | (SecurityProtocolType)768 | (SecurityProtocolType)3072;
或者
ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3
| SecurityProtocolType.Tls
| (SecurityProtocolType)0x300 //Tls11
| (SecurityProtocolType)0xC00; //Tls12
2.複製下面登錄檔程式碼匯入到登錄檔。新建txt，將字尾txt改為reg（登錄檔項），匯入
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\WinHttp] "DefaultSecureProtocols"=dword:00000800 [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Internet Settings\WinHttp] "DefaultSecureProtocols"=dword:00000800 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.1\Client] "DisabledByDefault"=dword:00000000 "Enabled"=dword:00000001 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.1\Server] "DisabledByDefault"=dword:00000000 "Enabled"=dword:00000001 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Client] "DisabledByDefault"=dword:00000000 "Enabled"=dword:00000001 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Server] "DisabledByDefault"=dword:00000000 "Enabled"=dword:00000001
3. 升級 到 fromwork4.6 版本
4.
