Vue axios跨域请求问题

Question

1.vue axios跨域请求,后台已配置允许跨域,代理访问的时候还报错跨域
2.配置了代理访问地址还是localhost

---

axios.defaults.headers.common['Access-Control-Allow-Origin'] = "*";
axios.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded';

---

proxyTable: {

  '/apis': {
    target: 'http://192.168.1.109/xxx/aa', 
    changeOrigin: true,
    pathRewrite: {
      '^/apis': '' 
      }
  }
}

---

this.$http.post('/apis/bbb/cccc', {

  json:JSON.stringify({})
})
.then(function (response) {
  console.log(response);
})
.catch(function (error) {
  console.log(error);
});

3.请求结果报错

Request header field Access-Control-Allow-Origin is not allowed by Access-Control-Allow-Headers in preflight response.

Error: Request failed with status code 404

at createError (createError.js?16d0:16)
at settle (settle.js?db52:18)
at XMLHttpRequest.handleLoad (xhr.js?ec6c:77)

Answer 1

还需要设置Access-Control-Allow-Headers, 设置为这个值Access-Control-Allow-Headers, Origin,Accept, X-Requested-With, Content-Type, Access-Control-Request-Method, Access-Control-Request-Headers试试

Answer 2

你这个报错是因为你的请求中除了安全的头部字段额外加了Access-Control-Allow-Origin，后台并不允许这个字段
解决办法
后台配置响应头Access-Control-Allow-Headers中加上Access-Control-Allow-Origin
