如何使用 boto3 将文件或数据写入 S3 对象

<p>在 boto 3 中，‘Key.set_contents_from_’ 方法被替换为<br /> • <a href="https://boto3.readthedocs.io/en/latest/reference/services/s3.html#S3.Object.put" target="_blank">Object.put()</a><br /> • <a href="https://boto3.readthedocs.io/en/latest/reference/services/s3.html#S3.Client.put_object" target="_blank">Client.put_object()</a><br /> 例如：</p> <pre><code class="lang-">import boto3 some_binary_data = b'Here we have some data' more_binary_data = b'Here we have some more data' # Method 1: Object.put() s3 = boto3.resource('s3') object = s3.Object('my_bucket_name', 'my/key/including/filename.txt') object.put(Body=some_binary_data) # Method 2: Client.put_object() client = boto3.client('s3') client.put_object(Body=more_binary_data, Bucket='my_bucket_name', Key='my/key/including/anotherfilename.txt') </code></pre> <p>或者，二进制数据可以来自读取文件，如比较 boto 2 和 boto 3 的官方文件中所述：<br /> 存储数据<br /> 从文件、数据流或字符串中存储数据很容易：</p> <pre><code class="lang-"># Boto 2.x from boto.s3.key import Key key = Key('hello.txt') key.set_contents_from_file('/tmp/hello.txt') # Boto 3 s3.Object('mybucket', 'hello.txt').put(Body=open('/tmp/hello.txt', 'rb')) </code></pre>
