Axios跨域请求应该请求两次,第一次请求到服务器,请求的类型是OPTIONS
Request Method:
OPTIONS
如果后端解决了跨域请求,后端服务器应该在返回头里加上以下几个参数
Access-Control-Allow-Origin:*
Access-Control-Allow-Headers:x-requested-with,content-type,X-Token,x-custom-header,Accept,Authorization,other_header,x-csrf-token,Authentication
Access-Control-Allow-Methods: POST,GET,PUT,DELETE,PATCH,OPTIONS
Content-Type:text/html; charset=UTF-8
如果还是只有一个请求的话,可以尝试修改Content-Type
这个参数改成:
application/x-www-form-urlencoded; charset=UTF-8
