ArcGIS10.1python调用Admin API完成几何服务的启动

我们知道arcgisserver10.1提供一套全新的API叫Admin API他可完成对于server本身很多的控制,例如启用安全、创建集群、添加服务器等。下面一个简单的实例说明如何使用python这个API完成几何服务的启动工作。
# 代码
import httplib, urllib, json
import sys
import getpass

def main(argv=None):
print
print "This tool is a sample script that starts the Geometry service on a Server."
print

username = raw_input("Enter user name: ")
password = raw_input("Enter password: ")
serverName = raw_input("Enter server name: ")
serverPort = 6080

# Get a token
token = getToken(username, password, serverName, serverPort)
if token == "":
print "Could not generate a token with the username and password provided."
return

# Construct URL to start a service - as an example the Geometry service
serviceStartURL = "/arcgis/admin/services/utilities/Geometry.GeometryServer/start"

# This request only needs the token and the response formatting parameter
params = urllib.urlencode({'token': token, 'f': 'json'})

headers = {"Content-type": "application/x-www-form-urlencoded", "Accept": "text/plain"}

# Connect to URL and post parameters
httpConn = httplib.HTTPConnection(serverName, serverPort)
httpConn.request("POST", serviceStartURL, params, headers)

# Read response
response = httpConn.getresponse()
if (response.status != 200):
httpConn.close()
print "Error while attempting to start the service."
return
else:
data = response.read()
httpConn.close()

# Check that data returned is not an error object
if not assertJsonSuccess(data):
print "Error returned by operation. " + data
else:
print "Operation completed successfully!"

return

# A function to generate a token given username, password and the adminURL.
def getToken(username, password, serverName, serverPort):
# Token URL is typically http://server[:port]/arcgis/admin/generateToken
tokenURL = "/arcgis/admin/generateToken"

# URL-encode the token parameters
params = urllib.urlencode({'username': username, 'password': password, 'client': 'requestip', 'f': 'json'})

headers = {"Content-type": "application/x-www-form-urlencoded", "Accept": "text/plain"}

# Connect to URL and post parameters
httpConn = httplib.HTTPConnection(serverName, serverPort)
httpConn.request("POST", tokenURL, params, headers)

# Read response
response = httpConn.getresponse()
if (response.status != 200):
httpConn.close()
print "Error while fetching tokens from admin URL. Please check the URL and try again."
return
else:
data = response.read()
httpConn.close()

# Check that data returned is not an error object
if not assertJsonSuccess(data):
return

# Extract the token from it
token = json.loads(data)
return token["token"]

# A function that checks that the input JSON object
# is not an error object.
def assertJsonSuccess(data):
obj = json.loads(data)
if 'status' in obj and obj['status'] == "error":
print "Error: JSON object returns an error. " + str(obj)
return False
else:
return True
# Script start
if __name__ == "__main__":
try:
main(sys.argv[1:])
except Error:
print 'error'

运行程序会提示输入服务器相关的信息,输入正确后你就可以看到服务启动的相关信息。
