通过POST将数据从Angular发送到Springboot

import { HttpClient } from '@angular/common/http';

constructor(private http: HttpClient) { }

sendData(data: any) {
  const url = 'http://your-api-url'; // 替换为实际的API地址
  return this.http.post(url, data);
}

const data = { name: 'John', age: 25 }; // 替换为实际的数据
this.sendData(data).subscribe(
  response => {
    console.log('数据发送成功');
    // 处理响应数据
  },
  error => {
    console.error('数据发送失败');
    // 处理错误
  }
);

@RestController
@RequestMapping("/api")
public class DataController {
  
  @PostMapping("/data")
  public ResponseEntity<String> receiveData(@RequestBody DataModel data) {
    // 处理接收到的数据
    return ResponseEntity.ok("数据接收成功");
  }
}
