我认为另一种选择是:
是的,这是一种相当肮脏且低级的方法,但它应该可以正常工作
如果node-soap
对您不起作用,请使用node
request
module,然后根据需要将xml转换为json。
我的请求无法使用node-soap
,除了付费支持之外,对该模块没有任何支持,而这超出了我的资源。所以我做了以下事情:
curl http://192.168.0.28:10005/MainService/WindowsService?wsdl > wsdl_file.xml
File > New Soap project
并上传了我的wsdl_file.xml
。Show Request Editor
。从那里我可以发送一个请求并确保它可以正常工作,也可以使用Raw
或HTML
数据来帮助我建立一个外部请求。
我的要求来自SoapUI的Raw
POST http://192.168.0.28:10005/MainService/WindowsService HTTP/1.1
Accept-Encoding: gzip,deflate
Content-Type: text/xml;charset=UTF-8
SOAPAction: "http://Main.Service/AUserService/GetUsers"
Content-Length: 303
Host: 192.168.0.28:10005
Connection: Keep-Alive
User-Agent: Apache-HttpClient/4.1.1 (java 1.5)
来自SoapUI的XML
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:qtre="http://Main.Service">
<soapenv:Header/>
<soapenv:Body>
<qtre:GetUsers>
<qtre:sSearchText></qtre:sSearchText>
</qtre:GetUsers>
</soapenv:Body>
</soapenv:Envelope>
我使用以上内容构建了以下内容node
request
:
var request = require('request');
let xml =
`<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:qtre="http://Main.Service">
<soapenv:Header/>
<soapenv:Body>
<qtre:GetUsers>
<qtre:sSearchText></qtre:sSearchText>
</qtre:GetUsers>
</soapenv:Body>
</soapenv:Envelope>`
var options = {
url: 'http://192.168.0.28:10005/MainService/WindowsService?wsdl',
method: 'POST',
body: xml,
headers: {
'Content-Type':'text/xml;charset=utf-8',
'Accept-Encoding': 'gzip,deflate',
'Content-Length':xml.length,
'SOAPAction':"http://Main.Service/AUserService/GetUsers"
}
};
let callback = (error, response, body) => {
if (!error && response.statusCode == 200) {
console.log('Raw result', body);
var xml2js = require('xml2js');
var parser = new xml2js.Parser({explicitArray: false, trim: true});
parser.parseString(body, (err, result) => {
console.log('JSON result', result);
});
};
console.log('E', response.statusCode, response.statusMessage);
};
request(options, callback);
我设法使用soap,wsdl和Node.js,您需要使用以下命令安装soap npm install soap
创建一个名为的节点服务器server.js
,该服务器将定义要由远程客户端使用的肥皂服务。该肥皂服务根据体重(kg)和身高(m)计算体重指数。
const soap = require('soap');
const express = require('express');
const app = express();
/**
* this is remote service defined in this file, that can be accessed by clients, who will supply args
* response is returned to the calling client
* our service calculates bmi by dividing weight in kilograms by square of height in metres
*/
const service = {
BMI_Service: {
BMI_Port: {
calculateBMI(args) {
//console.log(Date().getFullYear())
const year = new Date().getFullYear();
const n = args.weight / (args.height * args.height);
console.log(n);
return { bmi: n };
}
}
}
};
// xml data is extracted from wsdl file created
const xml = require('fs').readFileSync('./bmicalculator.wsdl', 'utf8');
//create an express server and pass it to a soap server
const server = app.listen(3030, function() {
const host = '127.0.0.1';
const port = server.address().port;
});
soap.listen(server, '/bmicalculator', service, xml);
接下来,创建一个client.js
文件,该文件将使用定义的肥皂服务server.js
。该文件将提供用于soap服务的参数,并使用SOAP的服务端口和端点来调用url。
const express = require('express');
const soap = require('soap');
const url = 'http://localhost:3030/bmicalculator?wsdl';
const args = { weight: 65.7, height: 1.63 };
soap.createClient(url, function(err, client) {
if (err) console.error(err);
else {
client.calculateBMI(args, function(err, response) {
if (err) console.error(err);
else {
console.log(response);
res.send(response);
}
});
}
});
wsdl文件是用于数据交换的基于XML的协议,该协议定义了如何访问远程Web服务。调用您的wsdl文件bmicalculator.wsdl
<definitions name="HelloService" targetNamespace="http://www.examples.com/wsdl/HelloService.wsdl"
xmlns="http://schemas.xmlsoap.org/wsdl/"
xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"

希望能帮助到你
我发现仅使用Node.js将原始XML发送到SOAP服务的最简单方法是使用Node.js http实现。看起来像这样。
var http = require('http');
var http_options = {
hostname: 'localhost',
port: 80,
path: '/LocationOfSOAPServer/',
method: 'POST',
headers: {
'Content-Type': 'application/x-www-form-urlencoded',
'Content-Length': xml.length
}
}
var req = http.request(http_options, (res) => {
console.log(`STATUS: ${res.statusCode}`);
console.log(`HEADERS: ${JSON.stringify(res.headers)}`);
res.setEncoding('utf8');
res.on('data', (chunk) => {
console.log(`BODY: ${chunk}`);
});
res.on('end', () => {
console.log('No more data in response.')
})
});
req.on('error', (e) => {
console.log(`problem with request: ${e.message}`);
});
// write data to request body
req.write(xml); // xml would have been set somewhere to a complete xml document in the form of a string
req.end();
您将以字符串形式将xml变量定义为原始xml。
但是,如果您只想通过Node.js与SOAP服务进行交互并进行常规SOAP调用(而不是发送原始xml),请使用Node.js库之一。我喜欢node-soap。
根据您需要的端点数量,手动进行操作可能会更容易。
我已经尝试了10个库“ soap nodejs”,我终于手动完成了。
我在10多个跟踪WebApi(Tradetracker,Bbelboon,Affilinet,Webgains等)上成功使用了“ soap”包(https://www.npmjs.com/package/soap)。
问题通常来自这样一个事实,即程序员对于连接或验证远程API所需的内容并没有进行太多研究。
例如,PHP自动从HTTP标头重新发送cookie,但是当使用“ node”软件包时,必须显式设置(例如,通过“ soap-cookie”软件包)...
我使用节点net模块打开了Web服务的套接字。
/* on Login request */
socket.on('login', function(credentials /* {username} {password} */){
if( !_this.netConnected ){
_this.net.connect(8081, '127.0.0.1', function() {
logger.gps('('+socket.id + ') '+credentials.username+' connected to: 127.0.0.1:8081');
_this.netConnected = true;
_this.username = credentials.username;
_this.password = credentials.password;
_this.m_RequestId = 1;
/* make SOAP Login request */
soapGps('', _this, 'login', credentials.username);
});
} else {
/* make SOAP Login request */
_this.m_RequestId = _this.m_RequestId +1;
soapGps('', _this, 'login', credentials.username);
}
});
发送肥皂请求
/* SOAP request func */
module.exports = function soapGps(xmlResponse, client, header, data) {
/* send Login request */
if(header == 'login'){
var SOAP_Headers = "POST /soap/gps/login HTTP/1.1\r\nHost: soap.example.com\r\nUser-Agent: SOAP-client/SecurityCenter3.0\r\n" +
"Content-Type: application/soap+xml; charset=\"utf-8\"";
var SOAP_Envelope= "<?xml version=\"1.0\" encoding=\"UTF-8\"?>" +
"<env:Envelope xmlns:env=\"http://www.w3.org/2003/05/soap-envelope\" xmlns:SOAP-ENC=\"http://www.w3.org/2003/05/soap-encoding\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:n=\"http://www.example.com\"><env:Header><n:Request>" +
"Login" +
"</n:Request></env:Header><env:Body>" +
"<n:RequestLogin xmlns:n=\"http://www.example.com.com/gps/soap\">" +
"<n:Name>"+data+"</n:Name>" +
"<n:OrgID>0</n:OrgID>" +
"<n:LoginEntityType>admin</n:LoginEntityType>" +
"<n:AuthType>simple</n:AuthType>" +
"</n:RequestLogin></env:Body></env:Envelope>";
client.net.write(SOAP_Headers + "\r\nContent-Length:" + SOAP_Envelope.length.toString() + "\r\n\r\n");
client.net.write(SOAP_Envelope);
return;
}
解析soap响应,我使用了模块-xml2js
var parser = new xml2js.Parser({
normalize: true,
trim: true,
explicitArray: false
});
//client.net.setEncoding('utf8');
client.net.on('data', function(response) {
parser.parseString(response);
});
parser.addListener('end', function( xmlResponse ) {
var response = xmlResponse['env:Envelope']['env:Header']['n:Response']._;
/* handle Login response */
if (response == 'Login'){
/* make SOAP LoginContinue request */
soapGps(xmlResponse, client, '');
}
/* handle LoginContinue response */
if (response == 'LoginContinue') {
if(xmlResponse['env:Envelope']['env:Body']['n:ResponseLoginContinue']['n:ErrCode'] == "ok") {
var nTimeMsecServer = xmlResponse['env:Envelope']['env:Body']['n:ResponseLoginContinue']['n:CurrentTime'];
var nTimeMsecOur = new Date().getTime();
} else {
/* Unsuccessful login */
io.to(client.id).emit('Error', "invalid login");
client.net.destroy();
}
}
});
希望对别人有帮助
添加到Kim .J的解决方案:可以添加preserveWhitespace=true
以避免空白错误。像这样:
soap.CreateClient(url,preserveWhitespace=true,function(...){
您也可以使用wsdlrdr。EasySoap基本上是使用一些其他方法重写wsdlrdr的。请注意,easysoap没有wsdlrdr可用的getNamespace方法。
如果您只需要一次转换,则https://www.apimatic.io/dashboard?modal=transform可以让您通过建立免费帐户来实现此目的(无从属关系,对我来说才有用)。
如果您转换为Swagger 2.0,则可以使用
$ wget https://repo1.maven.org/maven2/io/swagger/codegen/v3/swagger-codegen-cli/3.0.20/swagger-codegen-cli-3.0.20.jar \
-O swagger-codegen-cli.jar
