记录vue springboot 跨域采坑

vue配置 域名src\main.js要与config\index.js一样

var axios = require('axios')
axios.defaults.baseURL = 'http://localhost:2020/api'
// 使请求带上凭证信息
axios.defaults.withCredentials = true

assetsSubDirectory: 'static',
assetsPublicPath: '/',
proxyTable: {
  '/api': {
    target: 'http://localhost:2020',
    changeOrigin: true,
    pathRewrite: {
      '^/api': ''
    }
  }
},

spring 配置com\evan\gd\config\MyWebConfigurer.java

@Override
public void addCorsMappings(CorsRegistry registry) {
    //所有请求都允许跨域，使用这种配置方法就不能在 interceptor 中再配置 header 了
    registry.addMapping("/**")
            .allowCredentials(true)
            .allowedOrigins("http://localhost:8080")
            .allowedMethods("POST", "GET", "PUT", "OPTIONS", "DELETE")
            .allowedHeaders("*")
            .maxAge(3600);
}
