回答1:

change

{
  "/api": {
  "target": "http://localhost:1234",
  "secure": false,
  "changeOrigin": true,
  "logLevel": "debug"
  }
}

to

{
  "/api": {
  "target": "http://localhost:1234",
  "secure": false,
  "changeOrigin": true,
  "logLevel": "debug",
"pathRewrite": {
      "^/api": ""
    }
  }
}

回答2:

You're matching only /api url. If you want to match urls that begin with /api but have something else use /api/*.

proxy.config.json

{
  "/api/*": {
    "target": "http://localhost:1234",
    "secure": false,
    "changeOrigin": true,
    "logLevel": "debug"
  }
}

Explanation

This configuration will proxy from local-server (lets suppose it is localhost:4200) to your target, so:

• localhost:4200/api --> http://localhost:1234/api
• localhost:4200/api/product --> http://localhost:1234/api/product
• localhost:4200 --> no proxy
• localhost:4200/whatever --> no proxy

If you want to exclude /api/ from the target route, include pathRewrite inside in proxy.config.json:

{
  "/api/*": {
    "target": "http://localhost:1234",
    "pathRewrite": { "^/api": "" },
    "secure": false,
    "changeOrigin": true,
    "logLevel": "debug"
  }
}
