angular - Web服务器不以角度运行代理配置脚本

Question

我最近将我的网站部署到服务器，但有一个问题是在发送 API 获取请求时出现错误 404。当我没有为代理配置 json 正确设置“ng serve”时，我之前遇到了这个错误。但是，我修复了所有错误，当我在 localhost 中使用“npm start”运行它时，我明白了

PS C:\Users\drago\Desktop\lol_search\lolsearch\searchLeague> npm start

search-league@0.0.0 startC:\Users\drago\Desktop\lol_search\lolsearch\searchLeague

ng 服务 --proxy-config=proxyconfig.json

** Angular Live Development Server 正在监听 localhost:4200，在http://localhost:4200/上打开浏览器**

一切都很完美。但是，自从我部署到服务器后，代理配置似乎又出现了错误。

这是 angular.json 文件

这是我的 proxyconfig.json

{
  "/api": {

    "secure": false,
    "changeOrigin": true,
    "pathRewrite": {
      "^/api": ""

    "secure": false,
    "changeOrigin": true,
    "pathRewrite": {
      "^/dragon": ""
    }
  }
}

对于任何解决方案，我都会非常感激。谢谢

更新

import { environment } from '../../environments/environment.prod';

const httpOptions = {
  headers: new HttpHeaders({
    'Content-Type':  'application/json',
  })
};


@Injectable()
export class SummonerService {

  private apiurl: string;
  baseApiUrl = environment.baseApiUrl;

  constructor(private  http:  HttpClient) {}

  setURL(name: string){
    this.apiurl = this.baseApiUrl + '/lol/summoner/v4/summoners/by-name/' + name + '?api_key=RGAPI-ea0b3ae8-d98b-45c6-adaa-f473fb3d3dc8';
      //this.apiurl = '/api/lol/summoner/v4/summoners/by-name/' + name + '?api_key=RGAPI-ea0b3ae8-d98b-45c6-adaa-f473fb3d3dc8';
  }
  setURL2(summonerID: string){
    this.apiurl = this.baseApiUrl + '/lol/league/v4/positions/by-summoner/' + summonerID + '?api_key=RGAPI-ea0b3ae8-d98b-45c6-adaa-f473fb3d3dc8';
    //this.apiurl = '/api/lol/league/v4/positions/by-summoner/' + summonerID + '?api_key=RGAPI-ea0b3ae8-d98b-45c6-adaa-f473fb3d3dc8';
   }

  getdata(name: string): Observable<LOLUserData>{
  this.setURL(name);
  return this.http.get<LOLUserData>(this.apiurl, httpOptions).pipe(
    map(res => res),
    catchError(error => {return throwError(true);}));
  }

这就是我所做的。首先，我在 environment.prod.ts 中为 api 设置了我的基本 url。在您发送给我的示例链接中，他们只是将 api 的基本 url 设置为变量，例如

出口常量环境= {生产：真，baseApiUrl：“ https://api.com ”}；

但这导致了 CORS 策略错误，所以我做了同样的事情，但使用 /api（proxyconfig.json 中的一个）来设置环境变量，如

出口常量环境= {生产：真，baseApiUrl：“/api”}；

它停止抛出 CORS 错误，但我仍然看到 404 错误，当然在 localhost 中，一切正常。

我不确定获取请求是否由于部署配置无效或为获取请求设置的 API URL 错误而失败。
