可以使用Newman JavaScript库。
使用纽曼作为一个库运行 Postman 收集node+纽曼运行事件的响应保存到文件。

演示步骤

通过SOAP API使用simple calculator进行演示。我将调用四个操作（+，/，*，-）
SOAP URL

http://www.dneonline.com/calculator.asmx

在header中，Content-Type应该是text/xml; charset=utf-8（而不是application/xml）

在POST的主体中，要求添加

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
    <soap:Body>
        <Add xmlns="http://tempuri.org/">
            <intA>14</intA>
            <intB>7</intB>
        </Add>
    </soap:Body>
</soap:Envelope>

第一步

使用REST API调用制作Postman集合

步骤二

导出集合集合文件名

simple-calculator.postman_collection.json

这是全套

{
    "info": {
        "_postman_id": "2700a5f9-223a-4641-9d97-0db0c88465fd",

        "schema": "https://schema.getpostman.com/json/collection/v2.1.0/collection.json",

    },

            },
            "response": []
        }
    ]
}

步骤三

创建写文件（.js）
完整的演示代码
保存resultSaveFile.js

const newman = require('newman'); // require newman in your project
const fs = require('fs');

// call newman.run to pass `options` object and wait for callback
newman.run({
    collection: require('./simple-calculator.postman_collection.json'),
    reporters: 'cli'
}).on('request', (error, data) => {
    if (error) {
        console.log(error);
    }
    const fileName = `${data.item.name}.XML`;
    fs.writeFile(fileName, data.response.stream.toString(), function (error) {
        if (error) {
            console.error(error);
        }
    })
})

步骤四

安装依赖项

npm install newman fs

步骤五

node resultSaveFile.js

结果

将保存四个文件（addition.XML、division.XML、multiplication.XML和subtraction.XML）
在addition.XML

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <soap:Body>
        <AddResponse xmlns="http://tempuri.org/">
            <AddResult>21</AddResult>
        </AddResponse>
    </soap:Body>
</soap:Envelope>
