在mysql中存储卷曲会话cookie(Storing curl session cookies in mysql)

 gsutil文档的Parallel Composite Uploads部分描述了如何解决这个问题（假设，如警告所指定的那样， crcmod模块可用的客户端将使用此内容）： 
 
gsutil -o GSUtil:parallel_composite_upload_threshold=150M cp bigfile gs://your-bucket
 
 从Python安全地做到这一点看起来像这样： 
 
filename='myfile.csv'
gs_bucket='my/bucket'
parallel_threshold='150M' # minimum size for parallel upload; 0 to disable

subprocess.check_call([
  'gsutil',
  '-o', 'GSUtil:parallel_composite_upload_threshold=%s' % (parallel_threshold,),
  'cp', filename, 'gs://%s/%s' % (gs_bucket, filename)
])
 
 请注意，在这里您明确提供了参数向量边界，并且不依赖于shell来为您执行此操作; 这可以防止恶意或错误的文件名执行不需要的操作。 
 
 
 如果您不知道访问此存储桶中的内容的客户端将具有crcmod模块，请考虑在上面设置parallel_threshold='0' ，这将禁用此支持。 

The Parallel Composite Uploads section of the documentation for gsutil describes how to resolve this (assuming, as the warning specifies, that this content will be used by clients with the crcmod module available):
 
gsutil -o GSUtil:parallel_composite_upload_threshold=150M cp bigfile gs://your-bucket
 
To do this safely from Python would look like:
 
filename='myfile.csv'
gs_bucket='my/bucket'
parallel_threshold='150M' # minimum size for parallel upload; 0 to disable

subprocess.check_call([
  'gsutil',
  '-o', 'GSUtil:parallel_composite_upload_threshold=%s' % (parallel_threshold,),
  'cp', filename, 'gs://%s/%s' % (gs_bucket, filename)
])
 
Note that here you're explicitly providing argument vector boundaries, and not relying on a shell to do this for you; this prevents a malicious or buggy filename from performing undesired operations.
 
 
If you don't know that the clients accessing content in this bucket will have the crcmod module, consider setting parallel_threshold='0' above, which will disable this support.
