target目标服务器
changeOrigin是否改写原始主机为目标url
pathRewrite重写路径，value替换key
var options = {
target: 'http://www.example.org', // 目标服务器 host
changeOrigin: true, // 默认false，是否需要改变原始主机头为目标URL
ws: true, // 是否代理websockets
pathRewrite: {
'^/api/old-path' : '/api/new-path', // 重写请求，比如我们源访问的是api/old-path，那么请求会被解析为/api/new-path
'^/api/remove/path' : '/path' // 同上
},
router: {
// 如果请求主机 == 'dev.localhost:3000',
// 重写目标服务器 'http://www.example.org' 为 'http://localhost:8000'
'dev.localhost:3000' : 'http://localhost:8000'
