希望一切都好！我是新来的，我有一个问题，我使用Mongoose，Express将这种post方法发布到mongoDB时遇到了这个问题，它没有进入集合，但是我正确连接到数据库，因为我看到MongoDB数据库连接已成功建立。终端，但我在应用程序的控制台中收到此404错误，其中包含来自我要放入地图集的练习集中的表格中的实际数据。这让我发疯了，因为我一直在谷歌上阅读和阅读他们的文档已有一段时间，但无法正确地连接各个部分。如果有任何帮助，将不胜感激。
<form action="/api/form" method="POST" onSubmit={handleSubmit}>
onSubmit={(values,actions) => {
setTimeout(() => {
axios
.post('/api/form',values,actions)
.then(response => {
console.log(response);
})
.catch(error => {
console.log(error.response);
});
console.log({ values,actions });
alert(JSON.stringify(values,null,2));
actions.setSubmitting(false);
},400);
}}
