发布到多普勒API时发生CORS错误

Question

我正在尝试使用其API将订户添加到Doppler的列表中，但它不断反复抛出CORS错误：

CORS Header 'Access-Control-Allow-Origin' is missing

发布数据的方式是下一个：

let options = {
          method: 'POST',
          url: `https://restapi.fromdoppler.com/accounts/${this.dopplerEmail}/lists/${this.dopplerNewsletterId}/subscribers`,
          params: {
            "email": this.email,
            "fields": [
              {
                "name": "FIRSTNAME",
                "value": this.name,
                "predefined": true,
                "private": true,
                "readonly": true,
                "type": "string"
              },
              {
                "name": "BIRTHDAY",
                "value": this.birthday,
                "predefined": true,
                "private": false,
                "readonly": false,
                "type": "date"
              },
              {
                "name": "CONSENT",
                "value": "True",
                "predefined": true,
                "private": false,
                "readonly": false,
                "type": "consent"
              }
            ]
          },
          headers: {
            'Authorization': `token ${this.dopplerApiKey}`,
          }
        }

        axios(options).then(r => {
          ... some logic
        }).catch(e => {
          console.log(e)
    });

我所有的变量都可以，所以我认为问题出在我的帖子设置之内，但我不知道是什么。

我正在使用Laravel 5.6，整个逻辑（包括表单本身）都在VueJS组件内部。
