我现在正在使用Angular 4.我没有在Angular 2或4中找到任何关于方法重载的正确解决方案.是否有可能在角度服务类中实现方法重载？或者我有兴趣知道它的细节.提前致谢.
我刚刚尝试像下面那样创建服务但发现Dublicate函数实现错误
ApiService.ts：
import { Injectable } from '@angular/core';
@Injectable()
export class ApiService {
constructor() { }
postCall(url,data,token) { // with three parameters
return resultFromServer; }
postCall(url,data) { // with two parameters
return resultFromServer;}
}
AuthenticationService.ts：
import { Injectable } from '@angular/core';
import { ApiService } from "app/_services/api.service";
import FunUtils from "app/_helper/utils";
@Injectable()
export class AuthenticationService {
constructor(private api: ApiService) { }
rest_login_call(userName,password) {
let data = { username: userName,password: password };
let url = "http://localhost:8000";
return this.api.postCall(url,data);
}
}
