Maybe the problem is not clearly described, what I want to achieve is this:

curve/tools/snaptool/curltool.py

Lines 85 to 95 in 6a74151

	def create_snapshot(user, filename, snapshotname):
	if user is None or filename is None or snapshotname is None:
	print('user, filename, snapshotname need')
	return
	params = {'Action':'CreateSnapshot', 'Version':'0.0.6', 'User':user, 'File':filename, 'Name':snapshotname}
	jsonobj = query(params)
	if jsonobj['Code'] != '0':
	print("create snapshot fail, ecode=%s, etext=%s" % (jsonobj['Code'], errcodelist[jsonobj['Code']]))
	return
	print("create snapshot success, UUID=%s" % jsonobj['UUID'])

There should be a problem with your implementation. What you want to achieve is this, which should be to create an http request.

Hi! I found the problem, which was caused due to my being misled into calling the wrong interface, and now two solutions come into my mind: 1. The client contracts an http packet. 2. Add a new roc interface. If you want a uniform format, we may use solution 2, but 1 is easier to achieve. @Cyber-SiKu
