正常情况下，代理返回的头信息为： HTTP/1.1 200 OK server?? ?Apache-Coyote/1.1 content-type?? ?application/json;charset=UTF-8 transfer-encoding?? ?chunked date?? ?Tue, 28 Jun 2016 02:07:39 GMT connection?? ?close 然而在IE8下面却返回了下面的头信息： HTTP/1.1 406 Not Acceptable server: Apache-Coyote/1.1 set-cookie: JSESSIONID=7F367B9EB53FDC8306D807E0A7BD4201; Path=/; HttpOnly content-type: text/html;charset=utf-8 date: Tue, 28 Jun 2016 02:01:31 GMT connection: close Transfer-Encoding: chunked 通过对比头信息，在代理设置里做了一下判断，在低版本IE浏览器重新设置一下头信息。

```js
|

|
||
var browserSync = require('browser-sync');
|
||
|
||
var proxyMiddleware = require('http-proxy-middleware');
|
||
|
||
var proxy_context = ['/service/web'];
|
||
var proxy_option = {
|
||
target: 'http://' + proxyConfig.host + ':' + proxyConfig.port,
|
||
//增加一个错误处理在window 7 ie7,8
|
||
onProxyReq: function(proxyReq, req, res){
|
||
var is4dot0 = false;
|
||
var acceptValue = "";
|
||
var acceptEncodeing = "";
|
||
var rawHeaders = req.rawHeaders;
|
||
|
||
rawHeaders.forEach(function(value, index){
|
||
if(value === "Accept"){
|
||
acceptValue = rawHeaders[index+1];
|
||
}
|
||
if(value === "Accept-Encoding"){
|
||
acceptEncodeing = rawHeaders[index+1];
|
||
}
|
||
if(value.indexOf("Mozilla/4.0") === 0){
|
||
is4dot0 = true;
|
||
}
|
||
});
|
||
if(is4dot0){
|
||
proxyReq.setHeader("Accept", acceptValue);
|
||
proxyReq.setHeader("Accept-Encoding", acceptEncodeing);
|
||
}
|
||
}
|
||
};
|
||
var proxy = proxyMiddleware(proxy_context, proxy_option);
|
||
|
||
browserSync({
|

host: 'local.xxx.com',
|

port: 3000,
|
||
open: 'external',
|
||
browser: 'google chrome',
|

ghostMode: false, // 每个页面的镜像独立，不相互影响
|

server: {
|

baseDir: "build",
|

middleware: [proxy]
|

}
