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

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' 解决: https://laracasts.com/discuss/channels/requests/request-to-api-cross-domain-cors-error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) } }) }View Code

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.
