从在代理后面运行的网站访问网络服务 [英] Accessing webservices from a website which is running behind a proxy

问题描述

我正在设计一个使用 ember 和 express over node 的网站.它在服务器中运行，例如:SERVER_1.

I am designing a website using ember and express over node. Its running in a server, say: SERVER_1.

我在另一台服务器上运行的 Web 服务很少，例如:SERVER_2.

I have few webservices running in another server, say: SERVER_2.

即:

SERVER_1 中的网站和 SERVER_2 中可用的网络服务

website in SERVER_1 and webservices available in SERVER_2

SERVER_1 位于代理服务器后面.我正在尝试从 SERVER_1 访问网络服务:

SERVER_1 is behind a proxy server. And I am trying to access webservices from SERVER_1:

SERVER_1 =====[PROXY]===> SERVER_2

当我从 SERVER_1 进行 AJAX 网络服务调用时，我收到:

When I make AJAX webservice calls from SERVER_1, I receive:

NetworkError: 500 Internal Server Error

但是，我能够通过浏览器成功检索值.仅通过 AJAX 代码，我正在检索网络 500 错误.

However, I am able to retrieve values successfully through browser. Only through AJAX code, I am retrieving Network 500 error.

同样为了测试，我删除了我的代理服务器设置:

Also for testing, I removed my proxy server setup:

SERVER_1 =====> SERVER_2

并且我能够通过 AJAX 代码和浏览器成功访问所有这些网络服务.

and I was able to access all those web services successfully both via AJAX code and browser.

如果我在它们之间有代理服务器:

If I have a proxy server in between them:

SERVER_1 =====[PROXY]===> SERVER_2

我得到 -- NetworkError: 500 Internal Server Error

我想知道从代理服务器后面运行的网站访问第三方网络服务的程序?

附加信息:

已经解决了跨域 web 服务访问问题(网站在一台服务器上运行，而 web 服务在其他一些具有不同端口的不同服务器上运行)，我正在使用 http-proxy npm，我的代码是如下:

Already to fix cross domain web-service access issue (website running in one server and webservices running in some other different servers with different ports), I am using http-proxy npm and my code is as follows:

var express = require('express');
var routes = require('./routes');
var http = require('http');
var path = require('path');
var httpProxy = require('http-proxy');
var endpoint  = {
    host:   'IP_ADDRESS_WHERE_MY_WEBSERVICES_RUN',
    port:   80,
    prefix: '/api'
}

var proxy = new httpProxy.RoutingProxy();
var app = express();

app.set('port', process.env.PORT || 3000);
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'ejs');
app.use(express.favicon());
app.use(express.logger('dev'));
app.use(express.methodOverride());
app.use(express.cookieParser('xxxxx'));
app.use(express.session());
app.use(app.router);
app.use(express.static(path.join(__dirname, 'public')));
app.use(function(req, res) {
    if (req.url.indexOf(endpoint.prefix) === 0) {
        proxy.proxyRequest(req, res, endpoint);
    }
});
app.use(express.bodyParser());

if ('development' == app.get('env')) {
    app.use(express.errorHandler());
}
app.get('/', routes.index);

http.createServer(app).listen(app.get('port'), function(){
    console.log('Express server listening on port ' + app.get('port'));
});

我的 AJAX 调用:

My AJAX call:

$.ajax({
            type: 'GET',
            async: false,
            url: 'API_URL',
            success: function (data) {
                alert('success');
            },
            failure: function(error){
                alert('error');
            }
        });

我已经使用 http-proxy 来处理所有 url 的请求了.

Already I using http-proxy to handle all url's request.

如何在上面的代码中配置我的代理服务器的IP地址和端口，以便我可以成功访问所有这些网络服务?或者有什么方法可以在 AJAX 调用中设置我的代理配置?

How can I configure my proxy server's IP address and port in the above code, so that I can access all these webservices successfully? Or is there some way to have my proxy configurations in AJAX call?

有人可以指导我吗?

谢谢

推荐答案

通常你需要同时做到这两点:

Usually you need to do both of these :

npm config set proxy your-proxy-address:portnpm 配置集注册表 "http://registry.npmjs.org/"

npm config set proxy your-proxy-address:port npm config set registry "http://registry.npmjs.org/"
