router.push()仅用于客户端导航，而不是API调用。
要调用API，需要使用fetch函数，如下所示

const res = fetch('/api/your-route', {
   method: 'POST', // change based on your request type.
   body: JSON.stringify(data) // if you have data to pass
}

字符串
现在，在/api/your-route/文件夹中，创建一个名为route.js的新文件，并将您的API逻辑传输到这里，如下所示：

export async function POST(req) {
  const data = await req.json() // to receive data
 // TODO: your API logic
 // note the name of the function must be the same as your method passed in
 // the fetch request that was made from the client side.
}
