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
