Angular-cli CORS设置

Question

我有后端url http://docker-users:5500/users?all=true，它返回我的用户列表。在angular-cli中，本地主机url是：http://localhost:4200。我已经设置了proxy.config.json并将其添加到ng serve中。问题是，当我试图到达时，我仍然收到404错误。我的错误在哪里呢？

proxy.config.json：

{
  "/api/*": {
    "target": "http://docker-users:5500",
    "secure": false,
    "changeOrigin": true
  }
}

service.ts

const headers = new Headers({ 'Content-Type': 'application/json;'});
const params = new URLSearchParams();
params.append('all', true);
const options = new RequestOptions({ headers: headers, params: params });
const resp = this.http.get('/api/users', options)
...

添加pathRewrite选项：

{
  "/api": {
    "target": "http://docker-users:5500",
    "secure": false,
    "pathRewrite": {
      "^/api": ""
    },
    "changeOrigin": true,
    "logLevel": "debug"
  }
}
