unity UnityWebRequest 上传文件添加时间字段和文件名字段 C# HttpListener接受

要在 Unity 中使用 UnityWebRequest 上传带有时间字段和文件名字段的文件，您可以使用以下代码：

IEnumerator UploadFile(string url, string filePath, string fileName)
{
    // Create a new UnityWebRequest
    UnityWebRequest request = UnityWebRequest.Post(url, new List<IMultipartFormSection>());

    // Set the content type
    request.SetRequestHeader("Content-Type", "multipart/form-data");

    // Create a new MultipartFormDataSection for the file
    byte[] fileData = File.ReadAllBytes(filePath);
    MultipartFormDataSection fileSection = new MultipartFormDataSection("file", fileData, fileName, "application/octet-stream");

    // Add the file section to the request
    request.multipartFormData.Add(fileSection);

    // Add the time field to the request
    request.AddField("time", DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss"));

    // Set the upload handler
    request.uploadHandler = new UploadHandlerRaw(request.multipartFormData.CreateByteArray());

    // Set the download handler
    request.downloadHandler = new DownloadHandlerBuffer();

    // Send the request
    yield return request.SendWebRequest();

    // Check for errors
    if (request.result != UnityWebRequest.Result.Success)
    {
        Debug.LogError(request.error);
    }
    else
    {
        Debug.Log("File uploaded successfully");
    }
}

要在 C# 中使用 HttpListener 接收带有时间字段和文件名字段的文件，您可以使用以下代码：

HttpListener listener = new HttpListener();
listener.Prefixes.Add("http://localhost:8080/");
listener.Start();

while (true)
{
    HttpListenerContext context = listener.GetContext();

    if (context.Request.HttpMethod == "POST")
    {
        // Get the time field value
        string time = context.Request.Form["time"];

        // Get the file field values
        HttpFileCollection files = context.Request.Files;
        HttpPostedFile file = files[0];
        string fileName = file.FileName;
        Stream fileStream = file.InputStream;

        // Save the file
        using (FileStream output = new FileStream(fileName, FileMode.Create))
        {
            fileStream.CopyTo(output);
        }

        // Send a response
        context.Response.StatusCode = 200;
        context.Response.Close();
    }
}

请注意，这只是一个基本示例代码，您需要根据您的具体需求进行修改。
