我正在尝试从 Ubuntu 操作系统上的节点.js服务器向 WSDL API 发送请求。我正在使用这样的node-soap：
'use strict';
const soap = require('soap');
// Other codes ....
soap.createClient( WSDL_URL, function(err, client) {
if (err) {
console.log('Client error: ', err);
return res.status(500).send('Not OK');
} else if (client){
client.MyFunction({header: {...headers}}, function(err2, result) {
console.log('client.lastRequest: ', client.lastRequest);
if (err2) {
console.log('Function err: ', err2);
return res.status(500).send('Not OK')
} else if (result) {
console.log('result: ', result);
return res.status(200).send('GETTest OK!');
}
});
}
});
我在函数调用(console.log('Function err: ', err2)(后收到此控制台错误：
{ TypeError: Cannot use 'in' operator to search for 'A' in svcutil.exe

当我使用 Wizdler 插件查看请求的可接受结构时，它看起来像这样：
<Envelope xmlns="http://schemas.xmlsoap.org/soap/envelope/">
<Body>
<FunctionName xmlns="http://something.something.com/">
<header>
<OtherDataTags xmlns="http://schemas.datacontract.org/2004/07/something.serviceName.Models">[string?]</OtherDataTags>
<OtherDataTags xmlns="http://schemas.datacontract.org/2004/07/something.serviceName.Models">[string?]</OtherDataTags>
<OtherDataTags xmlns="http://schemas.datacontract.org/2004/07/something.serviceName.Models">[string?]</OtherDataTags>
</header>
</FunctionName>
</Body>
</Envelope>
但lastRequest的结果是这样的：
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:msc="http://schemas.microsoft.com/ws/2005/12/wsdl/contract" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" xmlns:tns="http://something.something.com/" xmlns:q1="http://schemas.datacontract.org/2004/07/something.serviceName.Models" xmlns:q2="http://schemas.datacontract.org/2004/07/something.serviceName.Models" xmlns:q3="http://schemas.datacontract.org/2004/07/something.serviceName.Models" xmlns:q4="http://schemas.datacontract.org/2004/07/something.serviceName.Models" xmlns:q5="http://schemas.datacontract.org/2004/07/something.serviceName.Models" xmlns:q6="http://schemas.datacontract.org/2004/07/something.serviceName.Models" xmlns:q7="http://schemas.datacontract.org/2004/07/something.serviceName.Models" xmlns:q8="http://schemas.datacontract.org/2004/07/something.serviceName.Models" xmlns:q9="http://schemas.datacontract.org/2004/07/something.serviceName.Models" xmlns:q10="http://schemas.datacontract.org/2004/07/something.serviceName.Models" xmlns:q11="http://schemas.datacontract.org/2004/07/something.serviceName.Models">

<FunctionName xmlns="http://something.something.com/">
<header>
<OtherDataTags xmlns:q4="http://schemas.datacontract.org/2004/07/something.serviceName.Models">something</OtherDataTags>

</soap:Envelope>
好的，我找到了解决方案。创建客户端后，需要像这样设置端点：
'use strict';
const soap = require('soap');
// Other codes ....
soap.createClient( WSDL_URL, function(err, client) {
if (err) {
console.log('Client error: ', err);
return res.status(500).send('Not OK');
} else if (client){
client.setEndpoint(serviceURL); // <------ Add this. serviceURL is the WSDL_URL but without '?wdsl' at the end of the URL
client.MyFunction({header: {...headers}}, function(err2, result) {
console.log('client.lastRequest: ', client.lastRequest);
if (err2) {
console.log('Function err: ', err2);
return res.status(500).send('Not OK')
} else if (result) {
console.log('result: ', result);
return res.status(200).send('GETTest OK!');
}
});
}
});
