我有一个像https://example.com/TokenService?wsdl
这样的SOAP API,
我发送请求在以下函数中创建客户端:
let soap = require('soap');
soap.createClient(url, function(err, client) {
console.log('err is ',err) ;
client.myFunction(input_params, function(err, result) {
console.log(result);
});
});
然后我得到这样的错误:
错误:ENOENT:没有此类文件或目录,请打开“https:///example.com//TokenService?wsdl” 错误:-2,
代码:'ENOENT',
系统调用:'打开',
路径:'https://example.com/TokenService?wsdl`
我的客户端是不可取的。
答案 0 :(得分:3)
我认为你几乎就在那里。以下是您可以测试的电话示例:
const soap = require('soap');
const url = 'http://www.webservicex.net/globalweather.asmx';
const wsdlURL = 'http://www.webservicex.net/globalweather.asmx?WSDL';
soap.createClient(wsdlURL, {endpoint: url}, function(error, client) {
if (error) {
console.error(error);
} else {
client.GetCitiesByCountry({ CountryName: 'Russian Federation'}, function(error, result) {
if (error) {
console.error(error);
process.exit(1);
}
console.log(result);
});
}
});
我认为你可能只需要将两个url传递给函数,服务url和WSDL url。有时您不需要这样做,WSDL将包含指向所有操作URL的链接。如果省略{endpoint:url}选项,某些调用将起作用,而某些调用则不会。
同时检查WSDL链接,确保WSDL有效,您可以在浏览器中查看它,它应该如下所示:
http://www.webservicex.net/globalweather.asmx?WSDL
您也可以将WSDL下载到文件中并尝试:
"use strict";
const wsdlFileName = 'globalweather.wsdl';
const path = require('path');
const wsdlFile = path.join(__dirname, wsdlFileName);
const soap = require('soap');
const url = 'http://www.webservicex.net/globalweather.asmx';
soap.createClient(wsdlFile, {endpoint: url}, function(error, client) {
if (error) {
console.error(error);
} else {
client.GetCitiesByCountry({ CountryName: 'Russian Federation'}, function(error, result) {
if (error) {
console.error(error);
process.exit(1);
}
console.log(result);
});
}
});
您需要将WSDL文件放在与脚本相同的目录中。
我可以在C#客户端工作,XML POST看起来像这样:
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<s:Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<reservation xmlns="http://token.ws.web.cnpg/">
<Token_param xmlns="">
<AMOUNT>amount</AMOUNT>
<CRN>crn</CRN>
<MID>mid</MID>
<REFERALADRESS>referaladdress</REFERALADRESS>
<SIGNATURE>signature</SIGNATURE>
<TID>tid</TID>
</Token_param>
</reservation>
</s:Body>
</s:Envelope>
回复:
<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
<S:Body>
<ns2:reservationResponse xmlns:ns2="http://token.ws.web.cnpg/">
<return>
<result>3</result>
<token>Security check was not successful.</token>
</return>
</ns2:reservationResponse>
</S:Body>
</S:Envelope>
我可以通过执行以下操作对地址执行POST:
var request = require('request');
var url = 'https://example.com/TokenService';
var tokenXML = `<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<s:Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<reservation xmlns="http://token.ws.web.cnpg/">
<Token_param xmlns="">
<AMOUNT>amount</AMOUNT>
<CRN>crn</CRN>
<MID>mid</MID>
<REFERALADRESS>referaladdress</REFERALADRESS>
<SIGNATURE>signature</SIGNATURE>
<TID>tid</TID>
</Token_param>
</reservation>
</s:Body>
</s:Envelope>`;
console.log('Posting..')
console.log(tokenXML);
request.post(
{url: url,
body : tokenXML,
headers: {'Content-Type': 'text/xml'}
}, function optionalCallback(err, httpResponse, body) {
if (err) {
return console.error('upload failed:', err);
}
console.log('Upload successful! Server responded with:', body);
});
由于某种原因,NPM肥皂库不喜欢这个网络服务! 但是您可以自己填写XML中的值,如果您需要填写详细信息,它可能会让您更进一步。
我收到了回复:
<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
<S:Body>
<ns2:reservationResponse xmlns:ns2="http://token.ws.web.cnpg/">
<return>
<result>3</result>
<token>Security check was not successful.</token>
</return>
</ns2:reservationResponse>
</S:Body>
</S:Envelope>
但我不是用户名密码。如果您可以填写这些详细信息,那么您将获得成功的回复。你需要做一个NPM安装请求BTW来获取请求库。
