问题:

下面是客户端请求的正式报文,服务端无法获取输入参数,经过比较,发现用测试报文就可以,区别就是去掉了命名空间前缀cwmp,由于客户端是不能修改的,请问服务端需要怎么改才能正确识别输入的参数呢?

Answer 1

Hi,

>>下面是客户端请求的正式报文,服务端无法获取输入参数,经过比较,发现用测试报文就可以,区别就是去掉了命名空间前缀cwmp,

请问无法获取参数是指什么？是服务端接收不到请求还是在服务方法上打断点，代码可以执行到，但是方法的参数是空的？

客户端是如何生成客户端代码请求服务端的？

对于修改SOAP Request，我建议你测试下下面的代码。

# Capturing SOAP requests to an ASP.NET ASMX web service

Answer 3

客户端是如何生成客户端代码请求服务端的？一般来说，我们通过Add Service Reference或者wsdl.exe去生成客户端代码。不会出现参数不一致的问题。

这一条提示:未将对象引用设置到对象的实例

请帮忙分析一下是哪里的问题,^_^

Answer 5

你是怎么生成请求包的？

我建议你访问你的服务界面，Invoke那个方法，查看正确的SOAP Request.
