安装：npm install xml2js
使用：
var xml2js = require(\'xml2js\');
var builder = new xml2js.Builder(); // JSON->xml
var parser = new xml2js.Parser({ explicitArray: false }); //xml -> json
parser.parseString(body, function(err, result) {
console.log(err)
console.log(result)
})
。。。。。
xml = builder.buildObject（json）

function ksort(o) {
let sorted = {},
keys = Object.keys(o);
keys.sort();
keys.forEach((key)=>{
sorted[key] = o[key];
})
return sorted;
}
function toXml(_json){
var xml = \'<xml>\';
for (let key in _json) {
let val = _json[key];
if (
typeof val == \'string\' ||
typeof val == \'number\'
){
xml=xml+"<"+key+">"+val+"</"+key+">";
}else{
xml=xml+"<"+key+"><![CDATA["+val+"]]></"+key+">";
}
}
xml=xml+ \'</xml>\';
return xml;
}
function xmlToJson(xml){
var xmlParser = require(\'xml2js\').Parser({explicitArray : false, ignoreAttrs : true})
var promise = new Promise(function(resolve, reject){
xmlParser.parseString(xml,function (err, result) {
resolve(result.xml);
});
});
return promise;
}
