微信接口问题(The underlying connection was closed: An unexpected error occurred on a send)
突然在调用微信接口是报:The underlying connection was closed: An unexpected error occurred on a send错误,跟踪了半天,是因为在调用阿里人脸识别接口时,接认证设置成了SSL3,而微信接口支持TLS,所以就会报错。并且在更新后又正常的问题,
ServicePointManager.SecurityProtocol = SecurityProtocolType.SSL3;
