VUE AXIOS 跨域问题

背景:

   后台跨域使用通配符:context.Response.Headers.Add("Access-Control-Allow-Origin", "*");

  前端使用VUE axios 请求:

getData() {
this.$axios.get('http://127.0.0.1:8080/xxx/xxxxx',{
headers: {
"Content-Type":"application/json;charset=utf-8"
}
}).then( (response) => {
if( response.data.code === '0000'){
this.items = response.data.data.xxx;
console.log(this.items)
}
})
}
View Code

  

调试:

  报错:The value of the 'Access-Control-Allow-Origin' header in the response must not be the wildcard '*' when the request's credentials mode is ' include'
 

  添加  credentials: 'omit',

getData() {
        this.$axios.get('http://127.0.0.1:8080/xxx/xxxxx',{
          headers: {
            "Content-Type":"application/json;charset=utf-8"
          },
          credentials: 'omit',
        }).then( (response) => {
          if( response.data.code === '0000'){
            this.items = response.data.data.xxx;
            console.log(this.items)
          }
        })
      }

释义:https://developer.mozilla.org/zh-CN/docs/Web/API/Request/credentials

credentials 是Request接口的只读属性,用于表示用户代理是否应该在跨域请求的情况下从其他域发送cookies。这与XHR的withCredentials 标志相似,不同的是有三个可选值(后者是两个):

  • omit: 从不发送cookies.
  • same-origin: 只有当URL与响应脚本同源才发送 cookies、 HTTP Basic authentication 等验证信息.(浏览器默认值,在旧版本浏览器,例如safari 11依旧是omit,safari 12已更改)
  • include: 不论是不是跨域的请求,总是发送请求资源域在本地的 cookies、 HTTP Basic authentication 等验证信息.
