标题未设置[重复]

Question

我使用HttpClient发出请求，在每个请求上我都设置了头，但当我看到chrome网络选项卡时，这些头并没有设置。

密码

request(url: string, method: string, body?: Object) {
    // debugger;

    const fullUrl: string = this.baseUrl + '/' + url;
    var data: Object = new Object();

    const headers = new HttpHeaders();
    headers.append('Access-Control-Allow-Origin', '*');
    headers.append('Access-Control-Allow-Methods', 'GET,PUT,POST,DELETE');
    headers.append('Access-Control-Allow-Headers', "X-Requested-With, Content-Type");
    headers.append('Authorization', 'Bearer '+this.auth.getToken());
    headers.append('Accept', 'application/json');

    data['headers'] = headers;


    if (body) {
        // debugger;
        data['body'] = body;
    }


    return this.http.request(method, fullUrl, data)
        .map((res: Response) => res)
        .catch((err: Response) => this.onRequestError(err));
}

Answer 1

而不是data['Headers']=Headers；

尝试

const req = new HttpRequest(method, fullUrl, data, { headers })
return this.http.request(req)
      .map((res: Response) => res)
      .catch((err: Response) => this.onRequestError(err));
