VUE之axios解决跨域方案

跨域示例

Access to XMLHttpRequest at ‘xxxx’ from origin ‘http://localhost:8080’ has been blocked by CORS policy: Response to preflight request doesn’t pass access control check: No ‘Access-Control-Allow-Origin’ header is present on the requested resource.

解决

---

在vue.config.js中（vue-cli3之后需要自己建）

	   devServer: {
        host: 'localhost',
        port: 8080, // 端口
        https: false,
        proxy: {
            // 配置跨域

            '/api': {
                target: '目标域名 如 http://baidu.com',  // 代理的接口域名以及端口号；
                ws: true,   // 支持ws协议；websocket的缩写；
                changeOrigin: true,// 是否跨域
                pathRewrite: {     // 路径替换
                    '^/api': ''
                }
            }
        },
        hotOnly: false,
        before: app => { }
    },

接口调用

  this.$axios({
      url: "index",
      method: "get",
      params: {},
    }).then((res) => {
      console.log(res);
    });
