使用Javascript的最简单的SOAP示例是什么?

为了尽可能有用,答案应该是:

具有功能性(换句话说就是实际工作) 发送至少一个可以在代码的其他地方设置的参数 处理至少一个可以在代码的其他地方读取的结果值 适用于大多数现代浏览器版本 在不使用外部库的情况下,尽可能地清晰和简短

有人试过吗?https://github.com/doedje/jquery.soap

似乎很容易实现。

例子:

$.soap({
url: 'http://my.server.com/soapservices/',
method: 'helloWorld',

data: {
    name: 'Remy Blom',
    msg: 'Hi!'
},

success: function (soapResponse) {
    // do stuff with soapResponse
    // if you want to have the response as JSON use soapResponse.toJSON();
    // or soapResponse.toString() to get XML string
    // or soapResponse.toXML() to get XML DOM
},
error: function (SOAPResponse) {
    // show error
}
});

会导致

<soap:Envelope
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <helloWorld>
        <name>Remy Blom</name>
        <msg>Hi!</msg>
    </helloWorld>
  </soap:Body>
</soap:Envelope>

这是我能创建的最简单的JavaScript SOAP客户机。

<html>
<head>
    <title>SOAP JavaScript Client Test</title>
    <script type="text/javascript">
        function soap() {
            var xmlhttp = new XMLHttpRequest();
            xmlhttp.open('POST', 'https://somesoapurl.com/', true);

            // build SOAP request
            var sr =
                '<?xml version="1.0" encoding="utf-8"?>' +
                '<soapenv:Envelope ' + 
                    'xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" ' +
                    'xmlns:api="http://127.0.0.1/Integrics/Enswitch/API" ' +
                    'xmlns:xsd="http://www.w3.org/2001/XMLSchema" ' +
                    'xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">' +
                    '<soapenv:Body>' +
                        '<api:some_api_call soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">' +
                            '<username xsi:type="xsd:string">login_username</username>' +
                            '<password xsi:type="xsd:string">password</password>' +
                        '</api:some_api_call>' +
                    '</soapenv:Body>' +
                '</soapenv:Envelope>';

            xmlhttp.onreadystatechange = function () {
                if (xmlhttp.readyState == 4) {
                    if (xmlhttp.status == 200) {
                        alert(xmlhttp.responseText);
                        // alert('done. use firebug/console to see network response');
                    }
                }
            }
            // Send the POST request
            xmlhttp.setRequestHeader('Content-Type', 'text/xml');
            xmlhttp.send(sr);
            // send request
            // ...
        }
    </script>
</head>

    <form name="Demo" action="" method="post">

托马斯:

JSON是前端使用的首选,因为我们可以方便地查找。因此,您不需要处理XML。因此,不使用库的SOAP非常麻烦。有人提到SOAPClient,这是一个很好的库,我们的项目就是从它开始的。然而,它有一些局限性,我们不得不重写大量的内容。它以SOAPjs的形式发布,支持向服务器传递复杂的对象,并包括一些示例代理代码以使用来自其他域的服务。

最简单的例子包括:

Getting user input. Composing XML SOAP message similar to this <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> <soap:Body> <GetInfoByZIP xmlns="http://www.webserviceX.NET"> <USZip>string</USZip> </GetInfoByZIP> </soap:Body> </soap:Envelope> POSTing message to webservice url using XHR Parsing webservice's XML SOAP response similar to this <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> <GetInfoByZIPResponse xmlns="http://www.webserviceX.NET"> <GetInfoByZIPResult> <NewDataSet xmlns=""> <Table> <CITY>...</CITY> <STATE>...</STATE> <ZIP>...</ZIP> <AREA_CODE>...</AREA_CODE> <TIME_ZONE>...</TIME_ZONE> </Table> </NewDataSet> </GetInfoByZIPResult> </GetInfoByZIPResponse> </soap:Body> </soap:Envelope> Presenting results to user.

但是如果没有外部JavaScript库,就会有很多麻烦。

使用JavaScript轻松使用SOAP Web服务->

function fncAddTwoIntegers(a, b)
{
    varoXmlHttp = new XMLHttpRequest();
    oXmlHttp.open("POST",
 "http://localhost/Develop.NET/Home.Develop.WebServices/SimpleService.asmx'",
 false);
    oXmlHttp.setRequestHeader("Content-Type", "text/xml");
    oXmlHttp.setRequestHeader("SOAPAction", "http://tempuri.org/AddTwoIntegers");
    oXmlHttp.send(" \
<soap:Envelope xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' \
xmlns:xsd='http://www.w3.org/2001/XMLSchema' \
 xmlns:soap='http://schemas.xmlsoap.org/soap/envelope/'> \
  <soap:Body> \
    <AddTwoIntegers xmlns='http://tempuri.org/'> \
      <IntegerOne>" + a + "</IntegerOne> \
      <IntegerTwo>" + b + "</IntegerTwo> \
    </AddTwoIntegers> \
  </soap:Body> \
</soap:Envelope> \
");
    return oXmlHttp.responseXML.selectSingleNode("//AddTwoIntegersResult").text;
}

这可能不能满足你所有的要求,但这是回答你问题的一个开始。(我将XMLHttpRequest()切换为ActiveXObject("MSXML2.XMLHTTP"))。

问题是“使用Javascript的最简单的SOAP示例是什么?”

这个答案是Node.js环境中的一个例子,而不是浏览器。(让我们将脚本命名为SOAP -node.js)并且我们将使用来自欧洲PMC的公共SOAP web服务作为示例来获取一篇文章的参考列表。

const XMLHttpRequest = require("xmlhttprequest").XMLHttpRequest;
const DOMParser = require('xmldom').DOMParser;

function parseXml(text) {
    let parser = new DOMParser();
    let xmlDoc = parser.parseFromString(text, "text/xml");
    Array.from(xmlDoc.getElementsByTagName("reference")).forEach(function (item) {
        console.log('Title: ', item.childNodes[3].childNodes[0].nodeValue);
    });

}

function soapRequest(url, payload) {
    let xmlhttp = new XMLHttpRequest();
    xmlhttp.open('POST', url, true);

    // build SOAP request
    xmlhttp.onreadystatechange = function () {
        if (xmlhttp.readyState == 4) {
            if (xmlhttp.status == 200) {
                parseXml(xmlhttp.responseText);
            }
        }
    }

    // Send the POST request
    xmlhttp.setRequestHeader('Content-Type', 'text/xml');
    xmlhttp.send(payload);
}

soapRequest('https://www.ebi.ac.uk/europepmc/webservices/soap', 
    `<?xml version="1.0" encoding="UTF-8"?>
    <S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
    <S:Header />
    <S:Body>
        <ns4:getReferences xmlns:ns4="http://webservice.cdb.ebi.ac.uk/"
            xmlns:ns2="http://www.scholix.org"
            xmlns:ns3="https://www.europepmc.org/data">
            <id>C7886</id>
            <source>CTX</source>
            <offSet>0</offSet>
            <pageSize>25</pageSize>
            <email>ukpmc-phase3-wp2b---do-not-reply@europepmc.org</email>
        </ns4:getReferences>
    </S:Body>
    </S:Envelope>`);

在运行代码之前,你需要安装两个包:

npm install xmlhttprequest
npm install xmldom

现在你可以运行代码:

node soap-node.js
