预检的响应具有无效的HTTP状态代码405角度4

Question

我收到此错误：XMLHttpRequest无法加载http://api.azharcouncil.com/api/Employees/DeleteEmployee?id=11。试图从表格中删除员工时，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); 
    } 

**当我在邮递员尝试这个网址我可以删除员工**

我认为请求的内容类型应该是应用程序/ json也更改标题应附加键添加标题选项

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


}
