代理配置不适用于Angular CLI

Proxy configuration did not working with angular CLI

8080 –后端托管的端口
4200 –我的Angular2前端

在我的Angular2项目中，我有一个文件proxy.config.json，内容如下

{
"/api": {
"target":"http://localhost:8080",
"secure": false,
"changeOrigin":"true",
"pathRewrite": {"^/api":""}
}
}

在Angular2 package.json中，我将启动过程更改为"start":"ng serve --proxy-config proxy.config.json"
当我在Commander npm start中键入内容时，一开始我可以看到已创建代理：/ api-> http：// localhost：8080。好吧，到目前为止我认为还不错。

我正在尝试发送请求(Angular2)

constructor(private http: Http) {
this.getUsers();
}

getUsers(): any {
return this.http.get("/api/getusers")
.subscribe(response => {
console.log(response);
})
}

我收到http：// localhost：4200 / api / getusers 404(未找到)的错误消息。如我们所见，没有什么可以替代的。为什么？我做错什么了吗？
