Python卷曲到弹性搜索问题

Question

I am trying to use curl in python to push this command in Elastic search so that index patterns get created after the code finishes

        import pycurl
        import urllib
        import urllib2
        apiURL = 'http://localhost:9200/.kibana/index-pattern/james+_alerts* -d'
        c = pycurl.Curl()
        c.setopt(c.URL, apiURL)
        c.setopt(c.POSTFIELDS, '{"title" : james+"_alerts*",  "timeFieldName": "timeStamp"}')
        c.setopt(c.VERBOSE, True)
        c.perform()     
        c.close()

The output being returned is: -

* TCP_NODELAY set

What could potentially be the issue and fix for this?

Answer 1

You have extra '-d' in apiURL. I guess that it came from copy&paste from command line. If not, then you must encode url (urllib.urlencode)
