我正在尝试使用来自 https.request 的 XML 数据并将其以表格格式显示到网页中。我正在尝试遵循本教程，该教程描述了我想做的很好：https ://programmerblog.net/parse-xml-using-nodejs/
但是，我在过滤 XML 的结果时遇到问题。
这是我的代码：
// MODULES - INCLUDES
var xml2js = require('xml2js');
var parser = new xml2js.Parser();
module.exports = function (app) {
// FORM - SUBMIT - CUCMMAPPER
app.post('/cucmmapper/submit', function (req, res) {
// FORM - DATA COLLECTION
var cucmpub = req.body.cucmpub;
var cucmversion = req.body.cucmversion;
var username = req.body.username;
var password = req.body.password;
// JS - VARIABLE DEFINITION
var authentication = username + ":" + password;
var soapreplyx = '';
var cssx = '';
// HTTP.REQUEST - BUILD CALL
var https = require("https");
var headers = {
'SoapAction': 'CUCM:DB ver=' + cucmversion + ' listCss',
'Authorization': 'Basic ' + new Buffer(authentication).toString('base64'),
'Content-Type': 'text/xml; charset=utf-8'
};
// SOAP - AXL CALL
var soapBody = new Buffer('<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns="http://www.cisco.com/AXL/API/11.5">' +
'<soapenv:Header/>' +
'<soapenv:Body>' +
'<ns:listCss sequence="?">' +
'<searchCriteria>' +
'<name>%</name>' +
'</searchCriteria>' +
'<returnedTags uuid="?">' +
'<name>?</name>' +
'<description>?</description>' +
'<clause>?</clause>' +
'</returnedTags>' +
'</ns:listCss>' +
'</soapenv:Body>' +
'</soapenv:Envelope>');
// HTTP.REQUEST - OPTIONS
var options = {
host: cucmpub, // IP ADDRESS OF CUCM PUBLISHER
port: 8443, // DEFAULT CISCO SSL PORT
path: '/axl/', // AXL URL
method: 'POST', // AXL REQUIREMENT OF POST
headers: headers, // HEADER VAR
rejectUnauthorized: false // REQUIRED TO ACCEPT SELF-SIGNED CERTS
};
// HTTP.REQUEST - Doesn't seem to need this line, but it might be useful anyway for pooling?
options.agent = new https.Agent(options);
// HTTP.REQUEST - OPEN SESSION
let soapRequest = https.request(options, soapResponse => {
soapResponse.setEncoding('utf8');
soapResponse.on('data', chunk => {
soapreplyx += chunk
});
// HTTP.REQUEST - RESULTS + RENDER
soapResponse.on('end', () => {
console.log(soapreplyx);
parser.parseString(soapreplyx, function (err, result) {
// console.dir(result);
var cssx = result['soapenv']['ns']['return']['css'];
console.log(cssx);
res.render('cucmmapper-results.html', {
title: 'CUCM 2.1',
soapreply: soapreplyx,
css: cssx,
});
});
});
});
// SOAP - SEND AXL CALL
soapRequest.write(soapBody);
soapRequest.end();
});
}
我特别收到以下控制台错误。
TypeError: Cannot read property 'ns' of undefined
at C:\Users\PetersonA16\Desktop\listlineapp\listlineapp\routes\cucmmapper.js:68:39
以下结果：
console.log(soapreplyx);
用这个（编辑的）数据回复。
<?xml version='1.0' encoding='utf-8'?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Body>
<ns:listCssResponse xmlns:ns="http://www.cisco.com/AXL/API/11.0">
<return>
<css uuid="{E85C54E1-5737-7516-FFFC-14E97B1D0504}">
<description>description1</description>
<clause>something1</clause>
<name>name1</name>
</css>
<css uuid="{AFFC55A7-CD16-E250-09E8-9A12ABBE0C9E}">
<description>description2</description>
<clause>something2</clause>
<name>name2</name>
</css>
</return>
</ns:listCssResponse>
</soapenv:Body>
</soapenv:Envelope>
如果我取消注释该行：
console.dir(result);
我确实得到以下控制台输出：
{ 'soapenv:Envelope':
{ '$': { 'xmlns:soapenv': 'http://schemas.xmlsoap.org/soap/envelope/' },
'soapenv:Body': [ [Object] ] } }
我的理论是我需要使用 xml2js 选项。不过，经过一些实验，我还没有取得任何进展。
我还是 JS 的新手，所以任何帮助、指针或建议将不胜感激！
