我应该为每个文件上传请求创建一个新的boto3客户端实例，还是使用共享实例

Question

我想知道，应该为每个文件上传请求创建一个新的boto3客户端实例，还是使用共享实例？哪种方法正确？

每个上传请求创建一个新实例

@app.route('/', methods=['POST'])
def upload_file():
    file = request.files['file']

    file.save('/tmp/file.ext')

    client = boto3.client('s3')

    client.upload_file('/tmp/file.ext',  # Path to local file
        'my-space',  # Name of Space
        'file.ext')  # Name for remote file

---

每个上传请求的共享实例

client = boto3.client('s3')

@app.route('/', methods=['POST'])
def upload_file():
    file = request.files['file']

    file.save('/tmp/file.ext')

    client.upload_file('/tmp/file.ext',  # Path to local file
        'my-space',  # Name of Space
        'file.ext')  # Name for remote file

Answer 1

我会选择共享客户端。

client = boto3.client('s3')

@app.route('/', methods=['POST'])
def upload_file():
    file = request.files['file']

    file.save('/tmp/file.ext')

    client.upload_file('/tmp/file.ext', 'my-space', 'file.ext')
