【问题描述】：
我使用 soap package 编写了一个 soapService，我将一个快速服务器传递给它。
问题是服务器可以从 2 个不同的网络接口获取请求，而我想知道请求来自哪个网络接口。
我的解决方案是获取客户端的 IP 并确定它来自使用哪个接口
require("os").NetworkInterfaces()
但我找不到如何获取客户的 IP
我试过了： this.req.ip, this.httpHeaders["x-forwarded-for"] || this.req.connection.remoteAddres 但它是未定义的
编辑：我想添加一个最小的测试示例。
创建了3个文件： soapserver.js（包括我想从其中获取 ip 的 soap 服务） client.js（调用 soapservice） check_username.wsdl（用于创建服务）
soapserver.js：
var soap = require('soap');
var http = require('http');
const util = require('util');
const app = require("express")()
var myService = {
CheckUserName_Service: {
CheckUserName_Port: {
checkUserName: function(args, soapCallback) {
console.log('checkUserName: Entering function..');
console.log(args);
/*
* Where I'm trying to get clietn's IP address
*/
soapCallback("{'username found'}");
}
}
}
};
var xml = require('fs').readFileSync('check_username.wsdl', 'utf8');
var server = require("http").Server(app);
app.get('/', (req, res) => {
res.send("Hello World!");
console.log(req);
console.log(req.connection.remoteAddress);
console.log(req.ip);
});
var port = 8000;
server.listen(port);
var soapServer = soap.listen(server, '/test', myService, xml);
soapServer.log = function(type, data) {
console.log('Type: ' + type + ' data: ' + data);
};
console.log('SOAP service listening on port ' + port);
客户端.js：
"use strict";
var soap = require('strong-soap').soap;
var url = 'http://localhost:8000/test?wsdl';
var options = { endpoint: 'http://localhost:8000/test'};
var requestArgs = { userName: "TEST_USER" };
soap.createClient(url, options, function(err, client) {
if (err) {
console.error("An error has occurred creating SOAP client: " , err);
} else {
var description = client.describe();
console.log("Client description:" , description);
var method = client.checkUserName;
method(requestArgs, function(err, result, envelope, soapHeader) {
//response envelope
console.log('Response Envelope: \n' + envelope);
//'result' is the response body
console.log('Result: \n' + JSON.stringify(result));
});
}
});
检查用户名.wsdl
<definitions name = "CheckUserNameService"
targetNamespace = "http://www.examples.com/wsdl/CheckUserNameService.wsdl"
xmlns = "http://schemas.xmlsoap.org/wsdl/"
xmlns:soap = "http://schemas.xmlsoap.org/wsdl/soap/"
xmlns:tns = "http://www.examples.com/wsdl/CheckUserNameService.wsdl"
xmlns:xsd = "http://www.w3.org/2001/XMLSchema">
<message name = "CheckUserNameRequest">
<part name = "userName" type = "xsd:string"/>
</message>
<message name = "CheckUserNameResponse">
<part name = "status" type = "xsd:string"/>
</message>
<portType name = "CheckUserName_PortType">
<operation name = "checkUserName">
<input message = "tns:CheckUserNameRequest"/>
<output message = "tns:CheckUserNameResponse"/>
</operation>
</portType>
<binding name = "CheckUserName_Binding" type = "tns:CheckUserName_PortType">
<soap:binding style = "rpc"
transport = "http://schemas.xmlsoap.org/soap/http"/>
<operation name = "checkUserName">
<soap:operation soapAction = "checkUserName"/>
<input>
<soap:body encodingStyle = "http://schemas.xmlsoap.org/soap/encoding/" namespace = "urn:examples:CheckUserNameService" use = "encoded"/>
</input>
<output>
<soap:body encodingStyle = "http://schemas.xmlsoap.org/soap/encoding/" namespace = "urn:examples:CheckUserNameService" use = "encoded"/>
</output>
</operation>
</binding>
<service name = "CheckUserName_Service">
<documentation>WSDL File for CheckUserNameService</documentation>
<port binding = "tns:CheckUserName_Binding" name = "CheckUserName_Port">
<soap:address
location = "http://www.examples.com/CheckUserName/" />
</port>
</service>
</definitions>
【问题讨论】：
-
您已经在
/test上启动了您的 SOAP 服务器，但试图从/获取clientIP？我在这里错过了什么吗？req.connection.remoteAddress将为您提供/test上的客户端 IP。 -
@JishanShaikh 不，我想在 soap 服务代码中做类似的事情，我在其中留下了“我试图获取客户端 IP 地址的地方”评论
