调用第三方 api 时连接被拒绝错误

Question

我正在使用 Angular 创建一个项目并调用第三方 Web api 发布请求，但该请求未正确连接并给出连接被拒绝 cors 错误。此 api 可与一些 api 测试工具一起使用..这是我的请求

vehicleCheck(data) {
  let newHeaders = { headers: new HttpHeaders({ 'x-api-key': "xxxxxx" }) };
  return this.http.post('https://driver-vehicle-licensing.api.gov.uk/vehicle-enquiry/v1/vehicles',data,newHeaders);
}

当我联系api的开发者时，开发者的回复是：

However I would advise you to install a ‘curl version’ to get a feel of how the authentication mechanism works and you should configure your code to follow something like below:

 

 

$curl -d '{"registrationNumber": "KC07PZG"}' https://driver-vehicle-licensing.api.gov.uk/vehicle-enquiry/v1/vehicles -H "Content-Type: application/json" -H "Insert Key No" -v

你必须在这样的数据之后添加你的标题。

vehicleCheck(data) {
  let newHeaders = { headers: new HttpHeaders({ 'x-api-key': "xxxxxx" }) };
  return this.http.post('https://driver-vehicle-licensing.api.gov.uk/vehicle-enquiry/v1/vehicles',data, newHeaders);
}
