django - post to django API 在经过身份验证时返回 403 (Forbidden)，但在未经过身份验证时可以发布

问题描述

我正在构建一个应用程序，其工作方式如下：

用户在 html 表单上填写数据并提交。
数据发布到 API（通过 Fetch）。

这个应用程序使用 django、django rest 框架与纯 html 和 vanilla jav 我的问题是，当用户在 API/后端进行身份验证时，我无法发布。它返回 403。但是，当我未通过身份验证时，我可以从表单中发布数据。

这是 form.html 上的 JS，它将数据发布到 API：

<script>
  console.log('js linked')
  function getCookie(name) {
      var cookieValue = null;
      if (document.cookie && document.cookie !== '') {
          var cookies = document.cookie.split(';');
          for (var i = 0; i < cookies.length; i++) {
              var cookie = cookies[i].trim();
              // Does this cookie string begin with the name we want?
              if (cookie.substring(0, name.length + 1) === (name + '=')) {
                  cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
                  break;
              }
          }
      }
      return cookieValue;
  }
  var csrftoken = getCookie('csrftoken');

console.log(csrftoken)

  function post_report(event) {
    event.preventDefault();
    var contact_email = document.getElementById("contact_email").value
    var contact_number = document.getElementById("contact_number").value
    var date_time = document.getElementById("date_time").value
    var location = document.getElementById("location").value
    var description = document.getElementById("description").value
    console.log(contact_email + ' ' + description)


    fetch("http://127.0.0.1:8000/api/Flight_Safety_Reports/",{
      method: "POST",
      mode: 'same-origin',
      headers:{
        "Accept": "application/json",
        'Content-Type':'application/json',
        'X-CSRFToken': csrftoken
      },
      body: JSON.stringify({
        contact_email:contact_email,
        contact_number:contact_number,
        date_time:date_time,
        location:location,
        description:description

      })
    })
    .then(response =>console.log(response))

    alert('report submitted')

  }

重新迭代，当我没有登录到 api 时/当我没有登录到 django-admin 时，我可以发布。当我登录时，我收到 403 禁止错误。
