我用node-soap来调用java服务端的webservice。不传参数能够调用到，传参就报错

用的是npm install soap

var soap = require(‘soap’); var url = ‘http://localhost:8081/BSS/ws/userop?wsdl’; var args = {userId : 3};//不传参数是可以进入服务端的函数， soap.createClient(url, function(err, client) { console.log(client.UserServiceService.UserServicePort); client.getUserById(args, function(err, result) { //console.log(result); }); });

服务端直接报错说解析不了？有没有人知道是怎么回事啊？ 13:13:49,336 WARN PhaseInterceptorChain:452 - Interceptor for {http://ocedu.cn/}UserServiceService#{http://webservice.ocedu.com/}getUserById has thrown exception, unwinding now org.apache.cxf.interceptor.Fault: Unmarshalling Error: unexpected element (uri:"", local:“userId”).

唉。这个问题其实在当时已经解决了，现在才来补~~ 不够由于后来没有采用web service ,所以也就没管了，报错的原因是因为服务端生成 WSDL不一样，导致获取到的client下面属性层级结构是不确定的。还有参数什么的，有些自动生成的插件需要特定的参数，比较坑，解决办法很简单，断点查看client，知道具体结构就很好调用了；由于时间比较久了，记得不是很清楚了，希望对大家有用

一年后来更答案，楼主还是有心。
