Question

我使用LR VuGen 12.02和Web服务协议通过导入服务的WSDL来访问基于nettcp的WCF服务。

撰写请求并尝试发送后，我收到以下错误。实际上从WPF客户端可以正常工作，但LR VuGen脚本失败

    Action.c(16): Error:The socket connection was aborted. This could be caused by an error processing your message or a receive timeout being exceeded by the remote host, or an underlying network resource issue. Local socket timeout was '00:59:59.9949990'. 
Error: An existing connection was forcibly closed by the remote host

我已经尝试了很多相关但没有运气的建议供你参考： Increasing Timeouts and maxItemsInObjectGraph以及StackOverflow上的更多此类帖子，例如 Socket Connection Aborted-StackOverflow post

非常感谢任何帮助。

Web服务仅适用于HTTP绑定，而不适用于NetTCP绑定。对于NetTCP绑定，可以使用Visual Studio中的虚拟用户。使用客户端源构建shell以传递您的请求。您仍然可以从Visual Studio内部访问参数化引擎和运行时设置
