我正在处理我的react项目并尝试添加页面。所有模型，控制器和路径均已设置。但是表单的数据（来自我新添加的页面）没有将数据发布到mongodb集合中。我还创建了API。但是数据没有被发布
我认为所创建的API存在问题，它给出了400错误。请看一下我的代码，我没有得到背后的实际原因。这是代码
这是我的api-contactUs.js文件
const create = (contactUs) => {
return fetch('/api/contactUs', {
method: 'POST',
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json'
},
body: JSON.stringify(contactUs)
})
.then((response) => {
return response.json()
}).catch((err) => console.log(err))
}
export default create

答案 0 :(得分：0)
您没有提供任何错误消息，但我认为问题出在您的clickSubmit方法中，在contactUs对象中，您将字段“名称”设置了两次，而不是fname和lname。
