最简单的SOAP示例 - 开卷题库

小开

最简单的例子包括:

获取用户输入。

编写类似的XML SOAP消息

<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.

But it's a lot of hassle without external JavaScript libraries.

这不能直接用JavaScript完成，除非web服务与您的页面在同一个域上。编辑:在2008年和IE<10中，这不能用javascript直接完成，除非服务与你的页面在同一个域上。

如果web服务在另一个域中[并且您必须支持IE<10]，那么您将不得不在您自己的域中使用代理页面来检索结果并将结果返回给您。如果你不需要旧的IE支持，那么你需要在你的服务中添加CORS支持。在这两种情况下，您都应该使用类似timyates建议的库，因为您不希望自己解析结果。

如果web服务在您自己的域中，那么不要使用SOAP。这样做没有很好的理由。如果web服务在您自己的域中，那么修改它，使它能够返回JSON，从而避免处理SOAP带来的所有麻烦。

简单的回答是:不要用javascript发出SOAP请求。使用web服务从另一个域请求数据，然后在服务器端解析结果，并以js友好的形式返回。

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来使用来自其他域的服务。

浏览器处理XMLHttpRequest的方式有很多怪癖，这段JS代码将在所有浏览器上工作 https://github.com/ilinsky/xmlhttprequest 这段JS代码将XML转换为易于使用的JavaScript对象 http://www.terracoder.com/index.php/xml-objectifier

上面的JS代码可以包含在页面中，以满足您没有外部库的需求。

var symbol = "MSFT";
var xmlhttp = new XMLHttpRequest();
xmlhttp.open("POST", "http://www.webservicex.net/stockquote.asmx?op=GetQuote",true);
xmlhttp.onreadystatechange=function() {
if (xmlhttp.readyState == 4) {
alert(xmlhttp.responseText);
// http://www.terracoder.com convert XML to JSON
var json = XMLObjectifier.xmlToJSON(xmlhttp.responseXML);
var result = json.Body[0].GetQuoteResponse[0].GetQuoteResult[0].Text;
// Result text is escaped XML string, convert string to XML object then convert to JSON object
json = XMLObjectifier.xmlToJSON(XMLObjectifier.textToXML(result));
alert(symbol + ' Stock Quote: $' + json.Stock[0].Last[0].Text);
}
}
xmlhttp.setRequestHeader("SOAPAction", "http://www.webserviceX.NET/GetQuote");
xmlhttp.setRequestHeader("Content-Type", "text/xml");
var xml = '<?xml version="1.0" encoding="utf-8"?>' +
'<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> ' +
'<GetQuote xmlns="http://www.webserviceX.NET/"> ' +
'<symbol>' + symbol + '</symbol> ' +
'</GetQuote> ' +
'</soap:Body> ' +
'</soap:Envelope>';
xmlhttp.send(xml);

__abc0 -> __abc1

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。(我把XMLHttpRequest ()换成了ActiveXObject(“MSXML2.XMLHTTP”))。

你可以使用jquery。soap插件来为你做这项工作。

这个脚本使用$。ajax发送SOAPEnvelope。它可以接受XML DOM, XML字符串或JSON作为输入，响应也可以作为XML DOM, XML字符串或JSON返回。

站点的使用示例:

$.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
}
});

这里有一些很棒的例子(和一个现成的JavaScript SOAP客户端!) http://plugins.jquery.com/soap/

检查自述文件，并注意同源浏览器限制。

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>

Angularjs $http wrap基于XMLHttpRequest。只要在头内容设置下面的代码就可以了。

"Content-Type": "text/xml; charset=utf-8"

例如:

function callSoap(){
var url = "http://www.webservicex.com/stockquote.asmx";
var soapXml = "<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:web=\"http://www.webserviceX.NET/\"> "+
"<soapenv:Header/> "+
"<soapenv:Body> "+
"<web:GetQuote> "+
"<web:symbol></web:symbol> "+
"</web:GetQuote> "+
"</soapenv:Body> "+
"</soapenv:Envelope> ";


return $http({
url: url,
method: "POST",
data: soapXml,
headers: {
"Content-Type": "text/xml; charset=utf-8"
}
})
.then(callSoapComplete)
.catch(function(message){
return message;
});


function callSoapComplete(data, status, headers, config) {
// Convert to JSON Ojbect from xml
// var x2js = new X2JS();
// var str2json = x2js.xml_str2json(data.data);
// return str2json;
return data.data;


}

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
