我有asp.net web api服务器在调试中运行,单独的项目使用Angular 5 - 5.2.11。
我尝试删除数据但我不能,但是当我使用邮递员时,它可以正常工作。
import { Injectable } from '@angular/core';
import { HttpClient, HttpHeaders, HttpParams } from '@angular/common/http';
import { Observable } from 'rxjs/Observable';
import { map } from 'rxjs/operators';
@Injectable()
export class UserService { private getUserSucess: any;
private _headers = {
headers: new HttpHeaders().set('Content-Type', 'application/json')
};
private headers={
headers: new HttpHeaders({
'Content-Type': 'application/json'
});
}
constructor(private http: HttpClient) { }
deletUserHttp() {
return this.http.delete( 'http://localhost:52817/api/users/1' ).subscribe(deleteSucess.bind(this), deleteError.bind(this));
function deleteSucess(resp) {
debugger;
return resp;
}
function deleteError(resp) {
//resp = HttpErrorResponse {headers: HttpHeaders, status: 0, statusText: "Unknown Error", url: null, ok: false,
debugger;
return resp;
}
}
我也尝试使用:this._headers
和this.headars
结果相同:
HttpErrorResponse {headers:HttpHeaders,status:0,statusText:" Unknown Error",url:null,ok:false,
