localhost:

wepack设置时，使用代理

devServer: {
        hot: true,
        host: '0.0.0.0',
        port: "2023", // 项目启动端口, 默认8080
        //https: true, // 是否开启https 默认false
        // 代理设置
        proxy: {
            "/apl": {
                target: "127.0.0.1:3007",
                changeOrigin: true,
                pathRewrite: {
                    "^/apl": ""
                },
                // 解决本地请求https问题
                // secure: false,
                // headers: {
                //  Referer: "https://www.qzyxs.com"
                // }
            }
        }
    },

　　代理中的target参数未加协议名，默认相对地址，所以会自动在前面加上本地地址，http://localhost:加上 https:// 就可以了

devServer: {
        hot: true,
        host: '0.0.0.0',
        port: "2023", // 项目启动端口, 默认8080
        //https: true, // 是否开启https 默认false
        // 代理设置
        proxy: {
            "/apl": {
                target: "https://127.0.0.1:3007",
                changeOrigin: true,
                pathRewrite: {
                    "^/apl": ""
                },
                // 解决本地请求https问题
                // secure: false,
                // headers: {
                //  Referer: "https://www.qzyxs.com"
                // }
            }
        }
    },
