axios发送post请求，如何提交表单数据？

var app = new Vue({ el: "#register", data: { registerUrl: "/KindlePocket/bindingData" newUserInfo: { userName:'n', phone:'13', email:'12', emailPwd:'22', kindleEmail:'asd' } }, methods: { register: function() { axios.post(this.registerUrl, this.newUserInfo, { headers: { 'Content-Type': 'application/x-www-form-urlencoded' } }) .then(function (response) { console.log(response); }) .catch(function (error) { console.log(error); }); } } })
