Question

我在angular2中使用自定义标头"CLIENT-ID":"company"，后端使用jax rs。我在后端服务器中修复了Access-Control-Allow-Headers和所有CROS相关问题，如果我使用postman工作查找但是当我尝试使用角形式访问时，它给了我一个问题

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://localhost:8080/parkgarau-ws/rest/login. (Reason: missing token ‘client-id’ in CORS header ‘Access-Control-Allow-Headers’ from CORS preflight channel).

我不知道是什么问题，在服务器client-id中返回null并提供没有响应主体的选项respoonse 200

这是我的角度代码

login(loginUser: LoginUser) {
    console.log(JSON.stringify(loginUser));
    console.log(UrlConfig.BASE_URL + UrlConfig.LOGIN);
    return this._http.post(
        UrlConfig.BASE_URL + UrlConfig.LOGIN,
        JSON.stringify(loginUser),
        this.getHeaderInfo(loginUser.companyCode)
    )
        .map((response: Response) =>
            response.json()
        );

}
private getHeaderInfo(companyCode: string) {
    let headers = new Headers(

        );
    headers.append("CLIENT-ID",companyCode);
    headers.append("Content-Type", "application/json");
    headers.append("Accept", "application/json");
    console.log(headers);
    return new RequestOptions({ headers: headers });
}

这是我的http请求和响应
