Angular 2本地主机和后端服务器连接

您可以在本地环境中设置代理。

在你的 package.json "serve-dev": "<startApplication> --sourcemap=false --proxy-config proxy.config.json" .

并使用 npm run serve-dev

proxy.config.json 文件应如下所示:

{
  "/api/*":{
    "target":"http://localhost:5005",
    "secure": false,
    "logLevel": "debug"
  }
}

get 应该是这样的: this._http.get('./api/myEndpoint') .

app.use(express.static(publicPath)); // Set the path for express to use

// Add headers
app.use(function(req, res, next) {
  res.setHeader('Access-Control-Allow-Origin', '*');
  res.setHeader('Access-Control-Allow-Methods', 'GET, POST, PUT, DELETE');
  res.setHeader('Access-Control-Allow-Headers', 'X-Requested-With, Content-Type, Authorization');
  next();
});
