使用nodejs中httpProxy代理时候出现404异常的解决方

var http = require('http'),
  httpProxy = require('http-proxy');

var proxy = httpProxy.createProxyServer({});

var server = http.createServer(function(req, res) {
 
 
 proxy.web(req, res, { target: 'http://.blogs./xiaopen/' });
});

console.log("listening on port 5050")
server.listen(5050);

var http = require('http'),
  httpProxy = require('http-proxy');

var proxy = httpProxy.createProxyServer({});

var server = http.createServer(function(req, res) {
 
 delete req.headers.host;
 proxy.web(req, res, { target: 'http://.blogs./xiaopen/' });
});

console.log("listening on port 5050")
server.listen(5050);
