## HPE Aruba Networking ClearPass Server Readiness
These steps list what is required on the HPE Aruba Networking ClearPass server:
1. Create a new API Client within the HPE Aruba Networking ClearPass Guest Portal 
    - client id = demo, 
    - enabled, Operating Mode = Rest API
    - Operator Profile = Pick one with apporpiate permission level or make a new one 
    - Grant Type = client credentials
    - Access Token Lifetime = 8 Hours
2. Optional but preferred: valid SSL cerfificate
3. Optional: API Service enabled within Services. You may use the template to help you do this. Only required when using 'Grant Type' of Password.

# Initial Usage Instructions

Within your favourite Python IDE environment, create an import reference

```python
from pyclearpass import *
```

Create a object to login into ClearPass. The login object needs to be passed to use any function within the ClearPass API.  
Three examples below shows how to create the login object (either one can be used, but not both).

1. Using client credentials

```python
login = ClearPassAPILogin(server="https://yourserver.network.local:443/api",granttype="client_credentials",
clientsecret="myclientsecretexample", clientid="myclientidexample", verify_ssl=False)
```

> 📘 
> 
> The login object will contain the APIToken once any function has been used. It obtains it once for the session and uses the same token through the execution of the rest of the script. You can extract this token and reuse it for other sessions if required (login.api_token). The token will only be available for reuse until the lifetime expires which was configured when specifying a new API Client within the ClearPass Guest Module.

2. Using an explicitly defined api_token. You can generate an API token by clicking on the API client and then clicking 'Generate Access Token'.

```python
login = ClearPassAPILogin(server="https://yourserver.network.local:443/api",api_token="yoursecretapitoken", verify_ssl=False)
```

Using the api token located in a file. You can generate an API token by clicking on the API client and then clicking 'Generate Access Token'. The Token file is expected in the following format and is expected to exist in the script execution folder. This is the preferred method to avoid having your credentials directly exposed in your script file. 

```json 
{"access_token":"your_token_here"}
```
The python file is expected in the following format
```python
token = Utils.get_token_from_file("token.json")
login = ClearPassAPILogin(server="https://yourserver.network.local:443/api",api_token=token, verify_ssl=False)
```

Find an API you want to use, by prefixing  `Api`  in your IDE and Intellisense will show the available APIs available. Each of the top level API category names are available as a module. Once you have chosen a specific API module to use, for example ApiPolicyElements, it will show you the available methods if you suffix a . to the command - `ApiPolicyElements.`

The example below prints a single the roles available within the ClearPass server.

```python
print(ApiPolicyElements.get_role(login)) 
```

By default, the example above returns the first 25 roles. To view more, the limit needs to be adjusted. Placing your cursor over the .getRole will usually show you help about the method. 

```python
print(ApiPolicyElements.get_role(login, limit=100))
```

# Help

Once you have written a specific API  `ApiName.FunctionName(`, placing your cursor over the command will show you help for the function and what the required parameters are (example is Visual Studio Code). The first parameter is always login.  
You may also read the help for the function by calling `help(ApiName.function_name)`.  
Each function contains a help section on how to use it. 

# Python Package Upgrade Instructions

Once an update is available on the Python PyPi repository, you may upgrade your release by completing the following in a command line terminal - 

`pip3 install pyclearpass --upgrade`  
or  
`pip install pyclearpass --upgrade`

To install a specific version, execute the following command with x.x.x being the specific version number you want to install. 

`pip3 install pyclearpass==x.x.x`  
or  
 `pip install pyclearpass==x.x.x`
 
# Uninstall Package Package

To remove the Python pyclearpass package, type the following command into a command line terminal -  
`pip3 uninstall pyclearpass `  
or  
 `pip uninstall pyclearpass `

# Further Usage Examples

The examples below all exclude importing the module and creating the login variable. This is described directly below. Note, these are just a full examples, there are hundreds of API commands available within the SDK.

## Login
### Mandatory Login Session Parameters

The login variable only needs to be defined once in the script. Three examples are shown below to achieve this;

1. Using client_credentials

```python
from pyclearpass import *
login = ClearPassAPILogin(server="https://yourserver.network.local:443/api",granttype="client_credentials",
clientsecret="myclientsecretexample", clientid="myclientidexample", verify_ssl=False)
```

> 📘 
> 
> As mentioned earlier, the login object will contain the API Token once any function has been used. It obtains it once for the session and uses the same token through the execution of the rest of the script. You can extract this token and reuse it for other sessions if required (login.api_token). The token will only be available for reuse until the lifetime expires which was configured when specifying a new API Client within the ClearPass Guest Module.

2. Using an explicitly defined api_token. You can generate an API token by clicking on the API client and then clicking 'Generate Access Token'.

```python
from pyclearpass import *
login = ClearPassAPILogin(server="https://yourserver.network.local:443/api",api_token="yoursecretapitoken", verify_ssl=False)
```

3. Using the api token located in a file. You can generate an API token by clicking on the API client and then clicking 'Generate Access Token'. The Token file is expected in the following format and is expected to exist in the script execution folder. This is the preferred method to avoid having your credentials directly exposed in your script file. 

```json 
{"access_token":"your_token_here"}
```
The python file is expected in the following format
```python
token = Utils.get_token_from_file("token.json")
login = ClearPassAPILogin(server="https://yourserver.network.local:443/api",api_token=token, verify_ssl=False)
```
### Optional Login Session Parameters
 
You can also include a timeout on the within the ClearPassAPILogin class to define how long the web request should try before timing out.  An example is provided below of 10 seconds

```python
token = Utils.get_token_from_file("token.json")
login = ClearPassAPILogin(server="https://yourserver.network.local:443/api",api_token=token, verify_ssl=False,timeout=10)
```

This example adds new Network Access Devices based on the CSV (comma delimited values) named "network access devices.csv" with headings and content filled rows. 

| name  | description    | ip_address    | location |
| :---- | :------------- | :------------ | :------- |
| demo1 | example demo 1 | 192.168.100.1 | UK       |
| demo2 | example demo 2 | 192.168.100.2 | US       |

```python
import pandas as pd
df = pd.read_csv("network access devices.csv")

for index, items in df.iterrows():
    newnad = {
        "description": items["description"],  # Description of the network device. Object Type: string
        "name": items["name"],  # Name of the network device. Object Type: string
        "ip_address": items["ip_address"],  # IP or Subnet Address of the network device. Object Type: string
        "tacacs_secret": "testing123",  # TACACS+ Shared Secret of the network device. Object Type: string

```

## Update Network Device Group

This example updates an Network Device Group with additional IP Addresses 192.168.0.100 and 192.168.0.99.  
These Network Access Devices must of been added before they can be appended to the group.  

```python
getcurrentnads = ApiPolicyElements.get_network_device_group_name_by_name(login,name="Example")
newnads={"value" : "192.168.0.100, 192.168.0.98"}
newnads["value"]=getcurrentnads['value']+", "+newnads["value"]
print(ApiPolicyElements.update_network_device_group_name_by_name(login,name="Example",body=newnads))

```

> 🚧 Ensure completion of validation checks
> 
> Validate the Network Access Device exists and is not already part of the Network Device Group before attempting to append to the group.

## Add New Guest Device

This example adds a Guest Device including 

1. An expiry date within 24 hours in seconds 
2. Associated to the role ID of 3 (Guest in test environment)
3. Statically assigned MPSK password
