我正在做wsgi python并调用aws workspaces api来获取所有工作空间并在屏幕上呈现（网页）。但我看到我的日志，只是通过点击索引URL就可以调用该函数两次。
ws_butt='get'
request_body_size = int(environ.get('CONTENT_LENGTH', 0))
request_body = environ['wsgi.input'].read(request_body_size)
d = parse_qs(request_body)
ws_butt=d.get('ws_butt',['get'])[0]
if ws_butt.lower()=='get':
#calls describe_workspaces to fetch all the workspaces for the user
new_content=[]
for region,endpoint in region_endpoint_dict.iteritems():
code,content=describe_workspaces(region,endpoint[0],session_username=username)
#some processing on content and generate new_content
if new_content:
#some internal processing of replacing strings
return your_workspace_window(environ, start_response,my_response=new_content)
start_response('200 OK', [('Content-Type', 'text/html')])
html_output='''

是什么导致它致电＆＃34; describe_workspaces＆＃34;在forloop被称为＆gt; =每个地区2次？检查网络元素，所有看起来都很好200OK所以我不知道是什么导致所谓的重新加载。
