预检请求无法使用访存API调用带有keepalive的POST请求 [英] Preflight request failing on calling a POST request with keepalive using fetch api

问题描述

使用启用了keepalive的访存api调用POST请求时，出现错误Preflight request for request with keepalive specified is currently not supported.任何帮助，将不胜感激 .我正在beforeunload事件上调用此api.

I am getting an error Preflight request for request with keepalive specified is currently not supported on calling a POST request using the fetch api with keepalive enabled. Any help would be appreciated . I am calling this api on beforeunload event.

API请求

  fetch(uri, {
    method: 'POST',
    headers: {
      'Content-type': options.headers.get('content-type'),
      'Authorization': options.headers.get('authorization')
    },
    body: JSON.stringify(interactionBody),
    keepalive: true
  }).catch((e) => {
    console.log(e);
  });

推荐答案

我找到了一种解决方法，直到 Chrome问题已解决

I found a workaround until the Chrome issue fixed

在使用mode: 'same-origin'

fetch(uri, {
  method: 'POST',
  headers: {
    'Content-type': options.headers.get('content-type'),
    'Authorization': options.headers.get('authorization')
  },
  body: JSON.stringify(interactionBody),
  mode: 'same-origin',
  keepalive: true
})
