Question

我收到此错误：XMLHttpRequest无法加载http://api.azharcouncil.com/api/Employees/DeleteEmployee?id=11。当预测从表中删除员工时，预检的响应具有无效的HTTP状态代码405。

数据storage.service.ts：

deleteEmployee(employeeId: any){
    let url = 'http://api.azharcouncil.com/api/Employees/DeleteEmployee?id='+employeeId;
let headers = new Headers();
headers.append('Content-Type', 'applications/json')
let options = new RequestOptions({ headers: headers }); 
return this.http.delete(url, options)
.map(resp => resp.json());

    }

employees.component.ts：

onDelete(employeeId: any){

  this.dataStorageService.deleteEmployee(employeeId).subscribe(
    data => {
      console.log(data);
      return true;
        },
        error => {
          console.log(error.json().error);
          console.error("Error delete employes!");
          return false;
        }
       );
    console.log(employeeId);
   }

**当我在邮递员中尝试这个网址时，我可以删除员工**

我认为请求内容类型应该是 application / json 还要更改标题应该是添加标题选项的附加键
