Question

我在发送带有标头中的令牌的CORS请求时遇到问题。提取代码：

fetchApi() {
    fetch('http://some-link.com',
    {
        headers: {
          'Accept': 'application/json',
          'auth-token': 'xxxxxxxxx'
        },
        method: "GET"
    }).then(response => response.json())
        .then(function(response){
            this.setState({hits:response});
        }).catch(function(error) { console.log(error); });

        console.log(this.state.hits);
};

控制台日志：从原点“ http://some-link.com”到“ http://localhost:3000”的获取操作已被CORS策略阻止：在飞行前响应中，Access-Control-Allow-Headers不允许请求标头字段auth-token。 >

网络请求日志：

任何想法可能有什么问题吗？

Answer 1

您必须更改服务器设置以允许标头“ auth-token”。

执行此操作后，您的请求就会生效。

您当前允许使用“ auth_token”，而不是“ auth-token”。

或者，如下更改前端中的标头名称：

 headers: {
   'Accept': 'application/json',
   'auth_token': 'xxxxxxxxx'
 }

如何从React发送CORS请求？
