如何将MultipartFile从Java传递到Python？

public void processFile(MultipartFile file) {
    // 处理文件的逻辑
}

public void processFile(MultipartFile file) {
    try {
        byte[] fileBytes = file.getBytes();
        // 或者
        File tempFile = File.createTempFile("temp", null);
        file.transferTo(tempFile);
        // 处理文件的逻辑
    } catch (IOException e) {
        e.printStackTrace();
    }
}

public void sendFileToPython(MultipartFile file) {
    try {
        CloseableHttpClient httpClient = HttpClients.createDefault();
        HttpPost httpPost = new HttpPost("http://python-server/upload");
        ByteArrayEntity entity = new ByteArrayEntity(file.getBytes());
        httpPost.setEntity(entity);
        CloseableHttpResponse response = httpClient.execute(httpPost);
        // 处理Python端的响应
        httpClient.close();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

from flask import Flask, request

app = Flask(__name__)

@app.route('/upload', methods=['POST'])
def upload_file():
    file = request.files['file']
    # 处理文件的逻辑
    return 'File uploaded successfully'

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