问题描述

有人知道这是什么意思吗?

Does anyone know what this means?

这是我调用的方法:

_productsService = new ProductsPortTypeClient();_productsService.GetResortProducts(GetProductsCredentials(),GetResortProductParams());

_productsService = new ProductsPortTypeClient(); _productsService.GetResortProducts(GetProductsCredentials(), GetResortProductParams());

推荐答案

看起来是 SSL 认证有问题，握手阶段失败，可能两个实现不兼容，你可以查看响应的 WSDL 格式，如图确定应该使用什么格式进行通信并检查您发送的格式是否符合它(您可以使用任何类型的网络监控软件，例如 Microsoft Network Monitor)

It looks like a problem with SSL authentication, it fails at handshake phase, maybe two implementations are not compatible, you may check the WSDL format of the response, figure out what format should be used for communication and check if the one sent by you complies with it (you may use any kind of a network monitor software, eg. Microsoft Network Monitor)
