Angular 代理 - proxy.conf.json 中的意外标记

Question

我有一个有效的 Angular 6 设置来制作 HttpRequests，但我需要通过代理运行它们。所以我在 package.json:

旁边创建了一个 proxy.conf.json

{
  "/loans/": {
    "target" : "https://api.zonky.cz",
    "secure" : false,
    "changeOrigin" : true
  }
}

并像这样更新了我的 package.json：

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

在运行ning npm start 我得到：

有人知道我该如何解决这个问题吗？ JSON 验证者说我的 proxy.conf.json 是有效的 JSON.

编辑
我在 powershell 中创建了 proxy.conf.json 文件，如下所示：

echo >> proxy.conf.json

这显然弄乱了文件 - 当我从 windows 界面再次创建文件时它起作用了。

Answer 1

尝试创建新文件并复制到新文件：

{
  "\/api": {
    "target": "https://api.zonky.cz",
    "secure": false,
    "changeOrigin": true,
    "logLevel": "debug",
    "pathRewrite": {
      "^\/api": "/"
    }
  }
}
