当C#项目目标指向窗口7中的.Net Framework4.8时Http请求错误

Question

以前我的C#项目目标.Net框架4.6.1，在窗口7、8.1和10中工作良好。但是现在我将目标框架更改为.Net Framework4.8、window 8.1和10，但在HTTP中没有问题，但是fine 7错误。

"An error occurred while making the HTTP request to https://Test.123.com/API/ServiceRouter.svc. This could be due to the fact that the server certificate is not configured properly with HTTP.SYS in the HTTPS case. This could also be caused by a mismatch of the security binding between the client and the server."

备注

Http请求操作刚刚从我的服务platform.

• Nothing

• .Net Framework4.8中接收到一些数据，这些数据已经安装在window 7 (SP 1)中，改为在

上编码

大洲春。这段代码解决了我的问题：

"System.Net.ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Tls12;"

谢谢。
