问题
Our project is migrating to Angular4, and use @angular/common/http Httpclient
as the default network tool. But I found there are no body
params in delete function. How do I add the body to delete function? Thanks.
回答1:
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: ... })
回答2:
const httpOptions = {
headers: new HttpHeaders({ 'Content-Type': 'application/json' }), body: your body data
};
return new Promise(resolve => {
this.httpClient.delete(URL, httpOptions)
.subscribe(res => {
resolve(res);
}, err => {
resolve(err);
});
});
by using httpOptions, you can set header and body in it. please refer this https://angular.io/tutorial/toh-pt6#delete-a-hero

I also get this problem and my solution is creating a new HttpRequest
of delete method, then clone this request, reset its body with your data.
let req = new HttpRequest('DELETE', 'url');
let newReq = req.clone({body: [10]});
this.http.request(newReq).subscribe((res) => {
console.log(res);
}, (err) => {
console.log(err);
});
The clone()
is required, because the body still can not be directly set in the new HttpRequest()
.
