Fetch No 'Access-Control-Allow-Origin' header 存在 AWS api 网关

Question

我正在尝试向 AWS API 网关发送获取请求，但它一直给我这个错误。我在 WordPress 的管理员端进行操作。

Access to fetch at 'https://34557322456.execute-api.ap-southeast-1.amazonaws.com/V1/code?kdata=something' from origin 'https://mywebsite.online' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

这是请求

fetch('https://34557322456.execute-api.ap-southeast-1.amazonaws.com/V1/code?kdata=something', {
        method: 'GET',
        headers: {
          'Content-Type': 'application/json',
          'Access-Control-Allow-Origin': '*',
        },
      }).then(response => {
        return response.json()
      })
      .then(data => console.log(data))
      .catch(error => console.log(error));

请帮忙

headers 应该在服务器端，在您的 .php 文件中尝试这样的操作：

header("Access-Control-Allow-Origin: *");
header("Access-Control-Allow-Headers: 'X-Requested-With,content-type'");
header("Access-Control-Allow-Methods: 'GET, POST, OPTIONS, PUT, PATCH, DELETE'");
