Node.js Soap：rpc 样式绑定的无效消息定义

Question

我正在尝试使用来自节点的 wsdl。使用'vpulim / node-soap'。

我可以加载 wsdl，对其进行描述，甚至调用某些函数。但是，每当我尝试调用一个不需要任何参数的函数时，我都会收到错误：

assert.js:92
  throw new assert.AssertionError({
        ^
AssertionError: invalid message definition for rpc style binding
    at Client._invoke (/home/user/node_scripts/application/node_modules/soap/lib/client.js:126:12)
    at null.getManagedModules (/home/user/node_scripts/application/node_modules/soap/lib/client.js:87:10)
    at /home/user/node_scripts/application/client.js:9:12
    at /home/user/node_scripts/application/node_modules/soap/lib/soap.js:48:5
    at null.callback (/home/user/node_scripts/application/node_modules/soap/lib/soap.js:35:7)
    at /home/user/node_scripts/application/node_modules/soap/lib/wsdl.js:716:12
    at WSDL._processNextInclude (/home/user/node_scripts/application/node_modules/soap/lib/wsdl.js:732:12)
    at WSDL.processIncludes (/home/user/node_scripts/application/node_modules/soap/lib/wsdl.js:762:8)
    at /home/user/node_scripts/application/node_modules/soap/lib/wsdl.js:678:10
    at process._tickCallback (node.js:415:13)

这里是describe()：

{ AlertPollingService:
   { AlertPollingService:
      { getManagementModule: [Object],
        getEMConfig: [Object],
        getAlertSnapshot: [Object],
        getAlertSnapshots: [Object],
        getManagedModules: [Object],
        getAllIscopeManagmentModules: [Object],
        getAllFilteredIscopeManagmentModules: [Object],
        getAllAlertsSnapshot: [Object],
        getAllAlertsSnapshotForManagementModule: [Object],
        getAgentSnapshot: [Object],
        getAgentSnapshots: [Object] } } }

如果我运行以下代码，它可以正常工作。我还将包括来自 SoapUI 的肥皂请求：

var args = {manModuleName: 'MQ'}
soap.createClient(url, function(err, client) {
    console.log(client.describe());
    client.getManagementModule(args, function(err, result) {
        console.log(result);
    });
});

### SOAPUI REQUEST ###
<soapenv:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:aler="http://alerts.hidden.server.hidden.com">
   <soapenv:Header/>
   <soapenv:Body>
      <aler:getManagementModule soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
         <manModuleName xsi:type="xsd:string">MQ</manModuleName>
      </aler:getManagementModule>
   </soapenv:Body>
</soapenv:Envelope>

所以该函数可以正常工作，因为我能够传递一个 arg。但是，以下代码因上述错误而失败。您可以从 soapui 请求中看到没有预期的参数。它只是一个返回列表的函数调用。我试过设置空白参数、空参数等...无法正常工作。

soap.createClient(url, function(err, client) {
    console.log(client.describe());
    client.getManagedModules(function(err, result) {
        console.log(result);
    });
});

### SOAPUI REQUEST ###
<soapenv:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:aler="http://alerts.hidden.server.hidden.com">
   <soapenv:Header/>
   <soapenv:Body>
      <aler:getManagedModules soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/>
   </soapenv:Body>
</soapenv:Envelope>

关于如何让它发挥作用的任何想法？

我为此受苦了一段时间 - 我通过将 args 定义为“null”取得了成功：

soap.createClient(url, function(err, client) {
    console.log(client.describe());
    client.getManagedModules(null, function(err, result) {
        console.log(result);
    });
});
