สอบถามเรื่องการเรียก API จากเซิฟเวอร์อื่นหรือที่อื่นหน่่อยครับ Angular

{
  "/api": {
    "target": "https://mobile-api.test.ac.th",
    "secure": false,
    "changeOrigin": true
  }
}

"scripts": {
    "ng": "ng",
    "start": "ng serve --proxy-config src/proxy.config.json",
    "build": "ng build",
    "test": "ng test",
    "lint": "ng lint",
    "e2e": "ng e2e"
  }

"serve": {
          "builder": "@angular-devkit/build-angular:dev-server",
          "options": {
            "browserTarget": "web:build",
            "proxyConfig": "src/proxy.config.json"
          },
