将图像从flask发送到javascript

from flask import Flask, send_file

app = Flask(__name__)

@app.route('/image')
def send_image():
    # 读取图像文件
    image_path = 'path_to_image.jpg'
    return send_file(image_path, mimetype='image/jpeg')

if __name__ == '__main__':
    app.run()

var xhr = new XMLHttpRequest();
xhr.open('GET', '/image', true);
xhr.responseType = 'blob';

xhr.onload = function(e) {
  if (this.status == 200) {
    var blob = this.response;
    var img = document.createElement('img');
    img.onload = function(e) {
      // 图像加载完成后，可以将其添加到页面中
      document.body.appendChild(img);
    };
    img.src = URL.createObjectURL(blob);
  }
};

xhr.send();
