Below a small example of a POST request. This did not work on my computer due to an authentication error, but that just might be my proxy (the server supposedly does not require a token (but you may in your case).
More on getting a token here (include it in the params dictionary):
ArcGIS Help 10.1
import urllib
import urllib2
# a list of non existing object id's (to avoid deletion of features)
oids = [37,101,462]
ids = ",".join([str(oid) for oid in oids])
print ids
# encode the parameters, only specifying the list of objectids (simple case)
params = urllib.urlencode({'f': 'json', 'objectIds':ids})
print params
# taking the sample HomelandSecurity URL (hoping this doesn't affect my visit to the DevSummit next year)
queryURL = "https://sampleserver3.arcgisonline.com/ArcGIS/rest/services/HomelandSecurity/operations/FeatureServe..."
# use the request method on the urllib2 library
req = urllib2.Request(queryURL, params) # forces POST request (deleteFeatures can only be done with a POST request)
# get the response
response = urllib2.urlopen(req)
# assuming this query URL
jsonResult = json.load(response)
# do something with the response
print jsonResults
This will return a json list indicating the result of the deletion for each object id:
{
"deleteResults" : [
{
"objectId" : 37,
"globalId" : null,
"success" : false,
"error" :
{
"code" : -1,
"description" : "Delete for the object was not attempted. Object may not exist."
}
},
{
"objectId" : 101,
"globalId" : null,
"success" : false,
"error" :
{
"code" : -1,
"description" : "Delete for the object was not attempted. Object may not exist."
}
},
{
"objectId" : 462,
"globalId" : null,
"success" : false,
"error" :
{
"code" : -1,
"description" : "Delete for the object was not attempted. Object may not exist."
}
}
]}
Kind regards, Xander
