向服务器发送请求时，节点没有收到req.body

Question

when sending a request to the server, the node does not receive the req.body what could be the mistake?

react:

sendRequest('POST','http://127.0.0.1:5500/api/auth/register', {...form})

function sendRequest(method:string, url:string, bodyObj:any = null){
   return fetch(url, {
      method: method,
      headers: {
            'Content-Type': 'application/json'
         },
      body: JSON.stringify(bodyObj)
   }).then(response => response.json())
     .then(result  => result)
}

node:

router.post('/register',async (req,res)=>{
   console.log(req.body)
   res.status(200).json(req.body)
})

There are a few things going on here that might cause issues but I think the primary area to investigate is the sendRequest function is returning a Promise which is asynchronous but then it's also trying to .then within that same function.

Resolving or rejecting the return promise where you want to handle the data might be a better execution.

 // This returns a Promise function sendRequest(method, url, bodyObj) { return fetch(url, { method: method, headers: { 'Content-Type': 'application/json' }, body: JSON.stringify(bodyObj) }) } sendRequest('POST', 'http://127.0.0.1:5500/api/auth/register', { ...form }).then(result => { console.log(result) }).catch(err => { console.log(err) })
