您可以改用 HttpClient 类上的通用 request 方法.此方法在选项中具有主体.https://angular.io/api/common/http/HttpClient#members

例如this.http.request('delete', 'url', { body: ... })

You may use a universal request method on the HttpClient class instead. This method has the body in options. https://angular.io/api/common/http/HttpClient#members

e.g this.http.request('delete', 'url', { body: ... })
