方法一:
在vue.config.js中添加如下配置:
devServer:{
proxy:"http://localhost:5000"
}
说明:
方法二:
编写vue.config.js配置具体代理规则:
module.exports = {
devServer: {
proxy: {
'/api': {//匹配所有以‘/api’开头的请求路径
target: 'http://localhost:5000',//代理目标的基础路径
pathRewrite: {'^/api': ''},
ws: true,//用于支持websocket
changeOrigin: true//用于控制请求头中的host值
},
/* '/foo': {
target: ''
} */
'/api2': {
target: 'http://localhost:5001',
pathRewrite: {'^/api2': ''},
ws: true,//用于支持websocket
changeOrigin: true//用于控制请求头中的host值
},
}
}
}
注意:
changeOrigin设置为true时,服务器收到的请求头中的host为:localhost:5000
changeOrigin设置为false时,服务器收到的请求头中的host为:localhost:8080
changeOrigin默认值为true
