用ajax提交表单好吗,react 表单提交可以用ajax吗？怎么写比较健壮？

为了配合npm，我个人项目是用的ES6的Fetch来进行HTTP请求

import React from 'react';

class Test extends React.Component{

constructor(...props){

super(...props);

this.state = {

username:'',

password:''

};

}

http(url, options, type = 'json') {

options = options || {};

options.credentials = 'include';

return fetch(url, options).then((resp)=> {

if (resp.ok) {

return resp[type]();

} else {

return resp[type]().then((err)=> {

throw new AppError(err.errmsg, err.errcode);

});

}

});

}

onSubmit(e){

e.preventDefault();

this.http('/api/user/login', {

method: 'POST',

body: JSON.stringify(this.state),

headers: {

'Content-Type': 'application/json'

}

}).then((data)=> {

console.log(data);

}).catch((e)=>alert(e.message)});

}

render(){

return (

this.onSubmit(e)}>

this.setState({username:e.target.value})}/>

this.setState({password.target.value})}/>

提交

)

}
