axios携带token跨域请求

前端在axios中配置请求头

axios.defaults.headers.common['token'] = 'aaa111222';

后端设置支持跨域请求头token字段

response.setHeader("Access-Control-Allow-Origin","*");
response.setHeader("Access-Control-Allow-Methods", "POST,GET,OPTIONS,DELETE,HEAD,PUT,PATCH");
response.setHeader("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept, token");

携带token跨域请求成功的案例：

扩展：支持cookie模式

response.setHeader("Access-Control-Allow-Origin","http://www.lihefei.com"); //cookie模式下不能设置为*
response.setHeader("Access-Control-Allow-Methods", "POST,GET,OPTIONS,DELETE,HEAD,PUT,PATCH");
response.setHeader("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept, token");
response.setHeader("Access-Control-Allow-Credentials","true"); //保持前端跨域时携带的cookie
