我正在尝试在 header 中发送 x-api-key header ，如下所示
服务.ts
import { Injectable } from '@angular/core';
import { Http, Headers, RequestOptions, Response } from '@angular/http';
import { Observable } from 'rxjs/Observable';
import 'rxjs/add/operator/map';
@Injectable()
export class InsuranceServiceService {
public token: string;
constructor(private http: Http) {
const currentUser = JSON.parse(localStorage.getItem('currentUser'));
this.token = currentUser && currentUser.token;
}
createAuthorizationHeader(headers: Headers) {
headers.append('Content-Type', 'application/json');
headers.append('x-api-key', `xxxxxxxxxxxxxxxxxxxx`);
}
sendOTP(data: object): Observable<Object[]> {
const header = new Headers();
this.createAuthorizationHeader(header);
return this.http.post('http://my-omain.com/', data,
{
headers: header
})
.map((response: Response) => response.json());
}
}
但是，我收到以下错误:
Request header field x-api-key is not allowed by Access-Control-Allow-Headers in preflight response.
如何解决这个问题？有没有其他方法可以传递 x-api-key？
