解决axios跨域时，发送post请求变options的问题

[code]mounted() {
let config = {
headers : {
'Content-Type':'application/json;charset=UTF-8'
},
};

axios.post('http://scms.qccat.com/v1/statistic/info-stu.json',{
token:"da48d456dede0eb5c3cb03f4ccf64c01",
session_id:'1_stu_token_2',
relation_type:'1',
season_type:'1',
page:'1',
limit:'10',
}.stringify(this.userInfo),config
)
.then(body =>{
console.log(body.data);
this.content=body.data;
}
).catch(err=>{
console.log(err);
})

},
