Python API Wrapper Tutorial

This document introduces the Python API library which allows you to administer your MailStore Service Provider Edition via Python.

Installation

The API library is tested against Python 3.2 to Python 3.4. It is compatible with the 32bit and the 64bit versions of Python.

You can get your Python binary from the Python download page or you can install it using the package manager of you distribution.

Additionally you need the MailStore API library which has to be installed in your Python's site-packages directory. The location of the site-packages directory can be found with the following command

 python -c "from distutils.sysconfig import get_python_lib; print(get_python_lib())"

Log in

The library can be imported with

 import mailstore

You are able to instantiate the class directly

 speClient = mailstore.spe.Client(username="admin", password="admin", host="127.0.0.1", port=8470)

or by using the with statement (context manager)

 with mailstore.spe.Client(password="S3cR3t!", host="spe.domain.eu") as speClient:
     do_something()

Default values can be omitted.

The available log in arguments and default values are

 username = "admin"
 password = "admin"
 host = "127.0.0.1"
 port = 8470
 autoHandleToken = True
 waitTime = 2000
 logLevel = 2
 fileLogLevel = 0

When autoHandleToken is enabled, you do not have to care about long running processes, you just have to wait for the result. When this value is set to False, then the status token is returned and you have to handle the token manually. More about this later.

The waitTime value specifies the value that is passed to the get-status call. When you call a long running method like VerifyStore, this is the maximum amount of milliseconds you have to wait for a status update.

logLevel and fileLogLevel have to be in the range 0 to 4. The loglevels are defined as following

0 : "NONE"
1 : "ERROR"
2 : "WARNING"
3 : "INFO" 
4 : "DEBUG"

Log entries will be printed to stdout. The logfile will be created in the user's %temp% directory and starts with the prefix MailStorePyLib. logLevel and fileLogLevel do not have to match.

Log out

When you prefer the first log in method, you have to log out afterwards manually. When using the context manager method, the log out is done automatically when exiting the with block. The logoutHandler will close open log files, if necessary.

 speClient.logoutHandler()

Simple calls

Simple calls will return immediately

 print(speClient.GetEnvironmentInfo())
 
 {'antiXsrfToken': 'dUubPmGWEANyDxGbBvejCu6qSRUlkQYSiunQCGFkbWlu', 'logOutput': None, 'statusText': None, 'error': None, 'percentProgress': None, 'token': None, 'result': {'userName': 'admin', 'copyright': 'Copyright (c) 2005-2013 MailStore Software GmbH', 'systemProperties': {'totalPhysicalMemory': 2146947072, 'processors': ['Intel(R) Core(TM) i5-2400 CPU @ 3.10GHz'], 'operatingSystem': 'Microsoft Windows Server 2012 Standard'}, 'serverName': 'win2012spe', 'version': '8.5.0.9288', 'licenseeName': 'MailStore Software GmbH', 'licenseeID': 1}, 'statusVersion': 2, 'statusCode': 'succeeded'}

When the statusCode is succeeded the information is stored in the result field. When the process has ended with another status, like failed or cancelled the diagnosis information is stored in the error field.

When there are no HTTP errors, the returned value is always a python dictionary.

Simple examples

To get all user's detailed information you could

 with mailstore.spe.Client():
     instance = "test01"
     for user in speClient.GetUsers(instance)["result"]:
         print(speClient.GetUserInfo(instance, user["userName"])["result"])

A list with all assigned email address can be retrieved with

 with mailstore.spe.Client() as client:
     instID = "test01"
     emailaddresses = list()
     for user in client.GetUsers(instID)["result"]:
         info = client.GetUserInfo(instID, user["userName"])["result"]
         emailaddresses += info['emailAddresses']
     print(emailaddresses)

Long running calls

Long running calls like VerifyStore are running asynchronous on the instance. When autoHandleToken is set to True (default), the library polls the status in the background automatically and will return the final result when the process has ended. Set autoHandleToken to False to get the token. In this case you have to handle the token by youself. There are helper methods available.

 with mailstore.spe.Client(autoHandleToken=False) as client:
     instID = "test01"
     storeID = 1
     print(client.VerifyStore(instID, storeID))
 
 {'antiXsrfToken': '6h8HV67XSak+jpQ/e6X1ehLOrt9cPUGicfHQCGFkbWlu', 'logOutput': None, 'statusText': None, 'error': None, 'percentProgress': None, 'token': 'sa6431dcd1b3e48c4719cfe8a75612b88a', 'result': None, 'statusVersion': 0, 'statusCode': 'running'}

You are able to update the status manually by passing the token to the GetStatus method. The call has finished, when the statusCode has changed from running to something else.

 with mailstore.spe.Client(autoHandleToken=False) as client:
     instID = "test01"
     storeID = 1
     token = client.VerifyStore(instID, storeID))
     time.sleep(5)
     print(client.GetStatus(token))

 {'antiXsrfToken': '+MKktayBhloqEsqk3xNTssdwTHRxL5+UaPTQCGFkbWlu', 'logOutput': '  100 messages verified...\r\n  200 messages verified...\r\n  300 messages verified...\r\n  400 messages verified...\r\n  500 messages verified...\r\n  600 messages verified...\r\n  700 messages verified...\r\n', 'statusText': None, 'error': None, 'percentProgress': 17, 'token': 'sa92c717e75db26fa57fc09c5e95f7096d', 'result': None, 'statusVersion': 29, 'statusCode': 'running'}

One could pass the token to the HandleToken method, then the behavior is exactly the same, as when you would have set autoHandleToken=True.

 with mailstore.spe.Client(autoHandleToken=False) as client:
     instID = "test01"
     storeID = 38
     token = client.VerifyStore(instID, storeID)
     print(client.HandleToken(token))
 
 {'antiXsrfToken': 'KIMJdCpjcuD8O5+xPislG8OysJ0fPgXQcvHQCGFkbWlu', 'logOutput': 'Verifying file group #38...\r\nCreating a list of messages to be verified...\r\n389 messages are about to be verified.\r\nVerifying...\r\n  100 messages verified...\r\n  200 messages verified...\r\n  300 messages verified...\r\n  389 messages verified...\r\nFinished.

Alternatively one could pass the token to the HandleTokenIter method, then every status update is yielded.

 with mailstore.spe.Client(autoHandleToken=False) as client:
     instID = "test01"
     storeID = 38
     for status in client.HandleTokenIter(client.VerifyStore(instID, storeID)):
         print(status)

 [...]
     MaintainFileSystemDatabases(self, autoHandleToken=False)

You are able to set the token handling behavior globally and locally. When you instantiate the client with autoHandleToken=True you still are able to call ever with differnt behavior.

 with mailstore.spe.Client(autoHandleToken=True) as client:
     instID=  "test01"
     client.MaintainFileSystemDatabases(instID, autoHandleToken=False)

Cancelling long running calls

If you want to cancel a long running call, you have to pass the token of that call to the CancelAsync method

 import time
 
 with mailstore.spe.Client(autoHandleToken=False) as client:
     instID = "test01"
     storeID = 38
     token = client.VerifyStore(instID, storeID)
     time.sleep(2)
     print(client.CancelAsync(token))
     time.sleep(2)
     print(client.GetStatus(token))
 
 {'antiXsrfToken': 'DUs5EO8ZZ9A8S6lUB/uYwIsAFwTufVpCd/HQCGFkbWlu', 'logOutput': None, 'statusText': None, 'error': None, 'percentProgress': None, 'token': None, 'result': None, 'statusVersion': None, 'statusCode': None}
 {'antiXsrfToken': 'fYO6hoP7eKr1X1SDj++6hhwI9pTwD45Dd/HQCGFkbWlu', 'logOutput': 'Verifying file group #38...\r\nCreating a list of messages to be verified...\r\n3893 messages are about to be verified.\r\nVerifying...\r\n  100 messages verified...\r\n  200 messages verified...\r\n  300 messages verified...\r\n', 'statusText': None, 'error': None, 'percentProgress': 7, 'token': None, 'result': None, 'statusVersion': 17, 'statusCode': 'cancelled'}

Pretty Printing the output

There is a helper function that formats the returned values in more readable manner.

 mailstore.spe.pprint(client.GetUserInfo("test01","admin"))
