我正在使用角度CLI。
如何删除令牌参数名称和值?

let params = new HttpParams();
    params = params.append('siteId', 1);
    params = params.append('orgId', 2);
    params = params.append('token', 3);

到目前为止,这是我的代码:

validate(email) { 
  let params = new HttpParams(); 
  params = params.set('email', email); 
  params = params.set('siteId', this._global.SITEID); 
  params = params.set('orgId', this._global.ORGID); 
  params = params.set('domainName', this._global.DOMAIN_NAME); 
  params = params.set('token', this._global.getRandomUuid()); 
  params.delete('domainName',this._global.DOMAIN_NAME); 
  return this.api.call('member/duplicate', params); 
} 

call(url, params) { 
  // here I want to delete the token param name and value. 
}

Sumama答案是正确的,在给定request和params变量的情况下,以下代码应该可以正常工作,以便cloneRequest不会具有已删除的参数。

let newParams =  request.params.delete('parameter-name');
let clonedRequest = request.clone({ params: newParams });
