ionic rest http problems

Question

export class HttpService {
constructor(private http:HttpClient) {}
post(serviceName:string,date:any){
const data = {};
const headers= new HttpHeaders();
const option = { header: headers, widthCredintials:false };
const url = environment.apiUrl + serviceName;
return this.http.post(url, JSON.stringify(data),option);
}
}

错误：无过载匹配此调用选项

请帮我做什么？

检查下面的例子，希望这个能工作

post(serviceName:string,date:any){
const data = {};
const headers= new HttpHeaders();
const url = environment.apiUrl + serviceName;
return this.http.post(url, JSON.stringify(data),{ headers, withCredentials: false });
}
