如何解决NodeJ中的SOAP请求返回500内部服务器错误
此刻我正在做一个小项目，我必须向SAP PCo管理主机服务发出SOAP请求。
我研究了概念验证，并创建了一个客户端javascript文档，该文档工作得很好。因此，我尝试在服务器端的NodeJs中实现此脚本。因此，我用node-express创建了一个Web服务器，并用node-request发出了请求，但是如果我将请求发送给PCo Management Host Services，答案就是 500 Internal Server Error 。
>出于测试目的，PCo管理主机显示原始的http请求，如下所示：
POST LINKTOHOST HTTP/1.1
User-Agent: PCo
SOAPAction: urn:sap.com:pco.management/PCoManagementService/GetAgentInstancesRuntimeInfo
Authorization: Basic ********
Content-Type: text/xml
Host: HOST
Content-Length: 300
Expect: 100-continue
Accept-Encoding: gzip,deflate
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:urns="urn:sap.com:pco.management"><soap:Body><urns:GetAgentInstancesRuntimeInfo xsi:nil="true" /></soap:Body></soap:Envelope>
我接受了这个原始请求，并创建了自己的请求。这是我对概念的有效JavaScript证明：
var userName = prompt("Please Log in with your Windows User Account. Username:","");
var userPW = prompt("Passwort: ","");
reqAllAgentRuntimeInfo();
setInterval(function() {reqAllAgentRuntimeInfo()},5000);
/*
*
* Functions
*
*/
//Sends out the SOAP request via XMLHttpRequest
function reqAllAgentRuntimeInfo()
{
var xmlhttp = new XMLHttpRequest();
xmlhttp.open('POST','LINKTOHOST',true,userName,userPW);
var soapRequest =
'<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:urns="urn:sap.com:pco.management">' +
'<soap:Body>' +
'<urns:GetAgentInstancesRuntimeInfo xsi:nil="true" />' +
'</soap:Body>'+
'</soap:Envelope>';
xmlhttp.setRequestHeader('SOAPAction','urn:sap.com:pco.management/PCoManagementService/GetAgentInstancesRuntimeInfo');
xmlhttp.setRequestHeader('Authorization','Basic');
xmlhttp.setRequestHeader('Content-Type','text/xml');
xmlhttp.send(soapRequest);
xmlhttp.onreadystatechange = function()
{
//Test for Status Code 4 & 200 = OK
if(xmlhttp.readyState == 4 && xmlhttp.status == 200)
{
displayData(xmlhttp);
}
};
}
然后我创建了此服务器端NodeJs脚本，该脚本不起作用，我无法解释自己的原因。
const http = require('http'); // 1 - Import Node.js modules
const express = require('express');
const app = express();
const bodyParser = require('body-parser');
const port = 50001;
app.use(bodyParser.urlencoded({ extended: true}));
app.get('/',(req,res) =>
{
res.redirect('/logIn');
});
app.get('/logIn',res) =>
{
res.sendFile(__dirname + '/sites/logIn.html');
});
app.post('/logIn',res) =>
{
//Encode User Credentials
var base64url = require('base64url');
var credentials = 'Basic ' + base64url(req.body.userName + ':' + req.body.password);
var request = require('request');
let soapReq =
'<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:urns="urn:sap.com:pco.management">' +
'<soap:Body>' +
'<urns:GetAgentInstancesRuntimeInfo xsi:nil="true" />' +
'</soap:Body>'+
'</soap:Envelope>';
var options =
{
url: 'LINKTOHOST',method: 'POST',body: soapReq,headers:
{
'Host': 'HOST','Content-Length':soapReq.length,'Accept-Encoding': 'gzip,deflate','User-Agent': 'PCo','SOAPAction': "urn:sap.com:pco.management/PCoManagementService/GetAgentInstancesRuntimeInfo",'Authorization': credentials,'Content-Type': "text/xml"
}
};
let callback = (error,response,body) =>
{
if(!error && response.statusCode == 200){
console.log('PCo Communication raw result',body);
}
else
{
console.log('PCo Communication Error: ',response.statusCode,response.statusMessage);
}
}
console.log(options);
request(options,callback);
})
app.listen(port,() =>
{
console.log(`Webserver listening at http://localhost:${port}`);
});
如果有人能帮助我，我会很高兴。
谢谢。
解决方法
您的请求（{options}）已过日期
您用于request（）的{options}不再有效。较新版本的request（）可为您处理许多繁重的工作。请参阅下面概述的更改。
// REMOVE Immediate line break after =
let soapReq = '<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:urns="urn:sap.com:pco.management">' +
'<soap:Body>' +
'<urns:GetAgentInstancesRuntimeInfo xsi:nil="true" />' +
'</soap:Body>'+
'</soap:Envelope>';
在NODE中，变量分配不能以换行符开头。
// This will cause problems.
let x =
''+'y';
// Do it like this is OK.
let x = ''+
'y';
var options =
{
hostname: 'LINKTOHOST',// KEY NAME CHANGE: url -> hostname
auth: 'user:password',// Moved (No base64URLEncode())
method: 'POST',body: soapReq,headers:
{
// 'Host': 'HOST',---> REMOVE
// 'Authorization': credentials,---> Moved To Above
'Content-Length':soapReq.length,// May not be needed
'Accept-Encoding': 'gzip,deflate',// May not be need
'User-Agent': 'PCo','SOAPAction': "urn:sap.com:pco.management/PCoManagementService/GetAgentInstancesRuntimeInfo",'Content-Type': "text/xml"
}
};
request(options,function (response) {
console.log('STATUS: ' + response.statusCode);
console.log('HEADERS: ' + JSON.stringify(response.headers));
response.on('data',function (chunk) {
console.log('BODY: ' + chunk);
});
});

特别感谢factorypolaris。现在可以使用了。这是我的代码：
let soapReq = '<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:urns="urn:sap.com:pco.management">' +
'<soap:Body>' +
'<urns:GetAgentInstancesRuntimeInfo xsi:nil="true" />' +
'</soap:Body>'+
'</soap:Envelope>';
var options =
{
host: '127.0.0.1',auth: req.body.userName + ':' + req.body.password,method: 'POST',port: 55555,path: '/PCoManagement',//body: soapReq,-->*Remove this*
headers:
{
'SOAPAction': "urn:sap.com:pco.management/PCoManagementService/GetAgentInstancesRuntimeInfo",'Content-Type': "text/xml"
}
};
var req = http.request(options,function (response) {
console.log('STATUS: ' + response.statusCode);
console.log('HEADERS: ' + JSON.stringify(response.headers));
response.on('data',function (chunk) {
console.log('BODY: ' + chunk);
});
});
req.write(soapReq); //--> Add this to write your actual data to the message
req.end(); //--> Add end() to define the end of your request
