使用JQuery和Python发送图像

// HTML部分
<input type="file" id="imageInput">
<button id="sendButton">发送图像</button>

// JavaScript部分
$(document).ready(function() {
  $('#sendButton').click(function() {
    var fileInput = document.getElementById('imageInput');
    var file = fileInput.files[0];
    var formData = new FormData();
    formData.append('image', file);

    $.ajax({
      url: '/upload',
      type: 'POST',
      data: formData,
      contentType: false,
      processData: false,
      success: function(response) {
        // 处理后端返回的响应数据
        console.log(response);
      },
      error: function(xhr, status, error) {
        // 处理错误情况
        console.log(error);
      }
    });
  });
});

from flask import Flask, request

app = Flask(__name__)

@app.route('/upload', methods=['POST'])
def upload():
    file = request.files['image']
    # 处理图像数据，例如保存到本地或进行进一步的处理
    file.save('uploaded_image.jpg')
    return '图像上传成功'

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