尝试使用nodejs获取id参数并在angular中访问它

const express = require('express');
const app = express();

app.get('/api/:id', (req, res) => {
  const id = req.params.id;
  // 在这里可以对id进行处理或者查询相关数据
  res.send({ id: id });
});

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});

import { Component, OnInit } from '@angular/core';
import { HttpClient } from '@angular/common/http';

@Component({
  selector: 'app-your-component',
  templateUrl: './your-component.component.html',
  styleUrls: ['./your-component.component.css']
})
export class YourComponent implements OnInit {
  id: string;

  constructor(private http: HttpClient) { }

  ngOnInit(): void {
    this.getIdFromNode();
  }

  getIdFromNode(): void {
    const id = 'your-id'; // 替换为实际的id值
    this.http.get<any>(`http://localhost:3000/api/${id}`).subscribe(data => {
      this.id = data.id;
    });
  }
}

<p>ID: {{ id }}</p>
