我尝试使用Node Js和node-soap实现一个简单的SOAP Web服务，但是客户端在使用服务器时似乎有问题。

正如user 672320所指出的，client.js失败的原因是因为所使用的wsdl的格式是“RPC/literal”，但样式被设置为“document”而不是RPC。
事实上，五种格式中的任何一种都可以用于WSDL，每种格式都有不同的格式。
请参阅Which style of WSDL should I use?以取得有关使用哪种型式的讨论。
此外，给出的示例并不完整。
扩展版本见下文：
wsdl文件：
server.js:
client.js:
代码输出为：
ckocjqey2#
在wsdl文件中，我改变的是从文档到rpc的样式，试图使用client.js获得其他响应
我收到的是这个输出。
