【原创】Vue.js 中 axios 跨域访问错误

时间:2023-09-04 15:13:31

1、假如访问的接口地址为 http://www.test.com/apis/index.php  (php api 接口)

2、而开发地址为http://127.0.0.1:8080,当axios发起请求时,出现如下错误:

Failed to load http://www.test.com/apis/index.php?&act=login: The value of the 'Access-Control-Allow-Origin' headerin the response must not be the wildcard '*' when the request's credentials mode is 'include'. Origin 'http://127.0.0.1:8080' is therefore not allowed access. The credentials mode of requests initiated by the XMLHttpRequest is controlled by the withCredentials attribute.

解决方法:
1、修改config/index.js, 修改 proxytable

    proxyTable: {
'/apis': {
target: 'http://www.test.com/apis/', // 接口地址
changeOrigin: true,
pathRewrite: {
'^/apis': '' //需要rewrite重写的,
}
}
},

2、重启 npm run dev    (很重要,否则不生效)

3、访问接口(访问时通过代理转发的,有点类似APACHE的urlrewrite,不需要完整http://www.test.com网址。)

                this.$api.get('/apis/index.php?act=login', {
"act": "login"
}, response => {
//success
},error => {
//error
}
);

  

大功告成,成功解决错误,另外:PHP端不需要做任何的header设置,网上很多教程胡说八道,根本不能实现跨域。
