我在我的应用程序中使用基于令牌的身份验证 我的后端是使用restful service(spring)开发的.后端代码很好地生成了所需的访问令牌和刷新令牌的时间轴,所以我已经覆盖了以下的http类:

export class customHttp extends Http {
   headers: Headers = new Headers({ 'Something': 'Something' });
    options1: RequestOptions = new RequestOptions({ headers: this.headers });
    private refreshTokenUrl = AppSettings.REFRESH_TOKEN_URL;
    constructor(backend: ConnectionBackend,
        defaultOptions: RequestOptions,private refresh:OauthTokenService) {
        super(backend, defaultOptions);
    }
    request(url: string | Request, options?: RequestOptionsArgs): Observable<Response> {
    console.log("custom http ");
        return super.request(url, options)
            .catch((err) => {
                if (err.status === 401) {
                    console.log(" custome http 401 ");
                    //   refresh the token
                    this.refresh.refresh().subscribe((tokenObj)=>{
                              console.log("tokenobj ");
                    })
                 } else {
                    console.log("err " + err); …

obj={
    "candidateFeedbackQuestionInfoId": 8
};

jsonobj=JSON.stringify(this.obj);

return this.http.delete(this.feebackUrl,this.jsonobj).map(this.extractData);

如果我们传递body来删除它会抛出类型不匹配错误,任何帮助都会很棒
