从soap XML响应中提取标记

Question

我正在尝试从SOAP xml响应中提取令牌。我尝试了各种片段，并得出以下结论:

var xml2js = require('xml2js');
var parser = new xml2js.Parser();

var options = {
"method": "POST",
"hostname": "www.titlepage.com",
"port": null,
"path": "/ws/TitleQuery.php",
"headers": {
"content-type": "text/xml",
"cache-control": "no-cache",

}
};


var req = http.request(options, function (res) {
var chunks = [];
res.on("data", function (chunk) {
chunks.push(chunk);
});
res.on("end", function () {
var body = Buffer.concat(chunks);
const xml = (body.toString());


parser.parseString(xml, function (err, result) {
if (err) {
console.error('here is the eror: ', err);
} else {
jsonLog = (JSON.stringify(result, null, 2));
console.log(result['SOAP-ENV:Envelope']['SOAP-ENV:Body'][0]['ns1:LoginResponse'][0]['Token']['0']); 
}
});
});
});
req.write("<?xml version="1.0"?>n<soap:Envelope xmlns:soap="http://www.w3.org/2001/12/soap-envelope" soap:encodingStyle="http://www.w3.org/2001/12/soap-encoding">n  <soap:Body xmlns:m="http://www.titlepage.com/ws">n    <m:Login>n      <m:UserName>a105yn</m:UserName>n      <m:Password>pink6PUPT1yult*kul</m:Password>n    </m:Login>n  </soap:Body>n</soap:Envelope>");
req.end();

结果是:

{
_: '312cb0ee6c346ee266dc95bc6c688021',
'$': { 'xsi:type': 'xsd:string' }
}
]

我如何进入最后一步并访问令牌(_ key)的值，_ key是什么?

Answer 1

你可以试试这个

var convert = require('xml-js');
var xml = `<?xml version="1.0"?>
<soap:Envelope xmlns:soap="http://www.w3.org/2001/12/soap-envelope" soap:encodingStyle="http://www.w3.org/2001/12/soap-encoding">
<soap:Body xmlns:m="http://www.titlepage.com/ws">
<m:Login>
<m:UserName>Username goes here</m:UserName>
<m:Password>Password goes here</m:Password>
</m:Login>
</soap:Body>
</soap:Envelope>`
var options = {compact: true, spaces: 4, elementNameFn: function(val) {return val.replace('soap:','');}};
var result = convert.xml2json(xml,options);

console.log(result);

var extract = JSON.parse(result)
console.log(extract.Envelope.Body['m:Login']['m:UserName']["_text"]) //Prints "Username goes here"
console.log(extract.Envelope.Body['m:Login']['m:Password']["_text"]) //Prints "Password goes here"
