A Native Collection has not been disposed, resulting in a memory leak. Allocated from:
Unity.Collections.NativeArray1:.ctor(Byte[], Allocator)
UnityEngine.Networking.UploadHandlerRaw:.ctor(Byte[])
UnityEngine.Networking.UnityWebRequest:SetupPost(UnityWebRequest, WWWForm)

The full text of the error is as above

See the solution first

     using (var request = UnityWebRequest.Post(serverURL, "POST"))
        using (var uh = new UploadHandlerRaw(bodyRaw))
        {
            //request.disposeUploadHandlerOnDispose = true;
            //request.disposeDownloadHandlerOnDispose = true;
            //request.disposeCertificateHandlerOnDispose = true;
            request.SetRequestHeader("Content-Type", "application/json;charset=utf-8");
            yield return request.SendWebRequest();
        }

This can be solved by using two using sets

I checked a lot of information on the Internet, and many people said that the memory leak was caused by the uploaderhandler they created not being released.

Many people say that using

            //request.disposeUploadHandlerOnDispose = true;
            //request.disposeDownloadHandlerOnDispose = true;
            //request.disposeCertificateHandlerOnDispose = true;

It's fine to set these three, but I tried it and the effect was not ideal. It may be due to problems with Unity itself, or it may have been changed.

Then I thought, can I release the uploadhandler manually? I tried it.

request.uploadHandler.Dispose();

The effect is not ideal. I even heard from an old man on the Internet that using the constructor to create

byte[] bodyRaw = Encoding.UTF8.GetBytes(send_data);
webRequest.uploadHandler = new UploadHandlerRaw(bodyRaw);

The effect is still not ideal.
