vue项目打包发布到Nginx后无法访问后端接口的解决办法

vue跨域代码
module.exports = {
  dev: {
    // Paths
    assetsSubDirectory: 'static',
    assetsPublicPath: '/',
    proxyTable: {
      '/api': {
        target: 'http://19二.168.0.100:8090/',  //要管束跨域的接心的域名
        secure:false,           //怎样是https接心，须要部署那个参数
        changeOrigin: true,  // 若何接心跨域，需求入止那个参数装备
        pathRewrite: {
          '^/api': ''  // 路径重写,那面的api包揽target内中的所在
        }
      }
    },

nginx配备文件代码

 #access_log  logs/host.access.log  main;

        location / {
            root   D:/xxx/web/vue001/;
            index  index.html index.htm;
        }

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 50两 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

        # proxy the PHP scripts to Apache listening on 1二7.0.0.1:80
        #
        location /api/{
        proxy_pass   http://19两.168.0.100:8090/;
        }
