即使我传递了正确的 FormData 文件图像，Formidable 也会返回 null 和两个空对象

问题描述

我有以下代码在提交表单时发生

data 包含文件，它控制台就好了。当我在下一个 JS 中将它传递给 formidable 时，它​​返回 Field 和 Files 的空对象，似乎无法弄清楚原因。

const formData = new FormData();
    formData.append("image",data.picture[0],data.picture[0].name);

    console.log(data.picture[0]);
    console.log(formData);

    console.log(formData.get("image"));

    const res = await fetch("../api/image",{
      method: "POST",headers: {
        "Content-Type": "application/json",},body: JSON.stringify(formData),});

import formidable from "formidable";

// first we need to disable the default body parser
export const config = {
  api: {
    bodyParser: false,};

export default async function image(req,res) {
  const form = new formidable.IncomingForm();
  form.uploadDir = "./";
  form.keepExtensions = true;
  form.parse(req,(err,fields,files) => {
    console.log(err);
    console.log(fields);
    console.log(files);
  });

  //console.log(form);

  //   cloudinary.uploader.upload(`${body}`,function (error,result) {
  //     console.log(result,error);
  //   });

  try {
    // const result = req.body;
    res.status(200).send({ message: "hello world" });
  } catch (error) {
    console.error(error);
    res.status(error.requestResult.statusCode).send(error.message);
  }
}

解决方法

最终使用 axios，不知道为什么它会超过 fetch，我也尝试了 fetch 中的内容类型更改

import tkinter
from tkinter import ttk
import time
import _thread

DELAY = 1000 # milliseconds

root = tkinter.Tk()
root.geometry('200x100')

chkValue = tkinter.BooleanVar(value=False)

def callBackFunc():
    global LOOP_ACTIVE
    print("button was clicked")
    LOOP_ACTIVE = False

def check_loop_status():
    global LOOP_ACTIVE
    if not LOOP_ACTIVE:
        root.destroy()  # OK in this function.
    root.after(DELAY,check_loop_status)  # Check again after delay.

chk = ttk.Checkbutton(root,variable=chkValue,text='Click me',command=callBackFunc)
chk.grid(column=0,row=0)

def loop_function():
    global LOOP_ACTIVE
    while LOOP_ACTIVE:
        print(f'Checkbutton state: {chk.state()}')
        time.sleep(5)

LOOP_ACTIVE = True
_thread.start_new_thread(loop_function,())
check_loop_status()  # Start periodic checking.
root.mainloop()
print("printed after mainloop ends")
