Question

我正在尝试从onesignal api发送POST请求

CODE

axios({
  method: 'post',
  url: 'https://onesignal.com/api/v1/notifications',
  headers: {
    'Authorization': 'Basic NTRjZDY1O....',
    'Content-type': 'application/json; charset=utf-8',
    'Access-Control-Allow-Origin':'*',
    'Access-Control-Allow-Methods': 'POST',
    'Access-Control-Allow-Headers':'*',
    'cache-control': 'no-cache'
  },
  data: {
    "app_id": "8e86143e-00.......",
    "contents": {
      "en": "test api"
    },
    "included_segments": [
      "All"
    ]
  }
}).catch(function (error) {
  if (error.response) {
    console.log('error-response-data-'+error.response.data);
    console.log('error-response-status-'+error.response.status);
    console.log('error-response-headers-'+error.response.headers);
  } else if (error.request) {
    console.log('error-request-'+error.request);
  } else {
    console.log('Error', error.message);
  }
});

错误输出

XMLHttpRequest无法加载https://onesignal.com/api/v1/notifications 请求标头字段不允许使用Access-Control-Request-Methods 预检响应中的Access-Control-Allow-Headers

error log

会解决它，但事实并非如此。有没有人有关于此错误的信息和/或我如何解决它？ 我正在使用firebase托管

应在服务器端启用

CORS 以访问API

Axios：请求标头字段Access-Control-Allow-Methods在预检响应中不允许使用Access-Control-Allow-Methods
