如何在响应头中将Content-Type:application/json改为html

app.get('/your-route', function(req, res) {
  res.setHeader('Content-Type', 'text/html');
  // 其他响应设置和发送代码
});

@app.route('/your-route')
def your_route():
  response = make_response()
  response.headers['Content-Type'] = 'text/html'
  # 其他响应设置和发送代码
  return response

@GetMapping("/your-route")
public ResponseEntity<String> yourRoute() {
  HttpHeaders headers = new HttpHeaders();
  headers.set("Content-Type", "text/html");
  // 其他响应设置和发送代码
  return new ResponseEntity<>("Your HTML content", headers, HttpStatus.OK);
}
