我的 javascript fetch API 调用有什么问题？

Question

我对 Django 后端服务器进行了 javascript 提取 API 调用

const res = fetch(url, {
  credentials: 'include',
  method: 'POST',
  mode: 'same-origin',
  headers: {
    'Accept': 'application/json',
    'Content-Type': 'application/json',
    'X-CSRFToken': csrftoken
  },
  body: JSON.stringify(requestBody),
  })
  .then((response) => response.json())
  .then((responseJson) => {
    return responseJson.movies;
  })
  .catch((error) => {
    console.error(error);
  });

如果我在请求中使用它之前在控制台上输出 requestBody，它看起来如下

{"add-Choice":["L"],"add-Left":["1"],"add-Right":["1"],"add-Value":["100"],"add-match":["8"],"user":["siteuser1"],"csrfmiddlewaretoken":["3K89ZvofjhIL2nZQoCcxphjmXborujsaLPn2FzlYiVmiBLODWhQQiAB5BhSXkQcF"],"add":["Submit"]}

此处字符串“add-”用作 Django 侧视图 post 方法的表单前缀。但是，在服务器视图端，如果我打印 request.POST 如下

def post(self, request, *args, **kwargs):
    print('Post request: ', request.POST)

我得到的输出是一个空的 QueryDict，如下所示

Post request:  <QueryDict: {}>
Internal Server Error: /matchoffers/8

请求被发送到正确的 URL 并被提取正确的视图-post 方法。但是它失败了，因为请求是空的。

If you're doing REST-based web service stuff ... you should ignore request.POST.
