在 IBM Cloud Storage 上使用 S3 .putobject 时出现 NoSuchKey 错误

Question

我正在学习 IBM 课程 Python for Data Science，在其中一个模块上，我不断收到一条错误消息。我按照说明使用 s3 和 putobject 将文件保存到 IBM 云对象存储上的存储桶。它给了我一个 NoSuchKey 错误，但密钥是在上面定义的

bucket_name = 'm4week5' 
html_path = '/home/dsxuser/work/index.html'
f = open(html_path,'r')
# Fill up the parameters in the following function:
# resource.Bucket(name=).put_object(Key=, Body=)
resource.Bucket(name = bucket_name).put_object(Key = html_path, Body = f.read())

错误信息：

NoSuchKey: An error occurred (NoSuchKey) when calling the PutObject operation: The specified key does not exist.

您收到此错误是因为您有不同的云存储端点

转至 IBM Watson studio 中的存储桶，选择存储桶端点选项，复制公共端点 URL 并将其替换在笔记本中的端点变量处，确保 https:// 存在。

更改 Key 参数 file_name = 'index.html' Key = file_name
