然后这里是使用 Axios 提交表单的 React。

return formData;
}
handleSubmit(event) {
Axios({
method: 'post',
headers: {"x-access-key": "Token Removed ;)"},
url: 'http://127.0.0.1:5000/register',
data: this.buildForm()
}).then(response => {
console.log(response)
console.log(response.data)
}).catch(error => {
console.log(error)
})
}
