## About
|
|
|
|
A stand-alone webserver that automatically generates forms from JSON to serve
|
|
as frontends to scripts.
|
|
|
|
ScriptForm takes a JSON file which contains form definitions. It then
|
|
constructs web forms from this JSON and serves these to users. The user can
|
|
select a form and fill it out. When the user submits the form, it is validated
|
|
and the associated script or Python callback is called. Data entered in the
|
|
form is passed to the script through the environment.
|
|
|
|
### Features
|
|
|
|
- Very rapidly construct forms with backends.
|
|
- Completely standalone HTTP server; only requires Python.
|
|
- Callbacks to any kind of script / program or to Python functions.
|
|
- User authentication support through Basic HTAuth.
|
|
- Validates form values before calling scripts.
|
|
- Uploaded files are automatically saved to temporary files, which are passed
|
|
on to the callback.
|
|
- Multiple forms in a single JSON definition file.
|
|
- Handles script / exception errors, HTML output or lets scripts and Python
|
|
callbacks stream their own HTTP response to the browser.
|
|
|
|
### Use-cases
|
|
|
|
Scriptform is very flexible and as such serves many use-cases. Most of these
|
|
revolve around giving non-technical users a user friendly way to safely run
|
|
scripts on a server.
|
|
|
|
Here are some of the potential uses of Scriptform:
|
|
|
|
- Add / remove users from htpasswd files.
|
|
- Execute SQL snippets.
|
|
- View service status
|
|
- Upload data to be processed.
|
|
- Restart, enable and disable services.
|
|
- Trigger for batch processing.
|
|
|
|
## Example
|
|
|
|
The following example lets you add new users to a htpasswd file via ScriptForm.
|
|
It presents the user with a form to enter the user's details. When the form is
|
|
submitted, the `job_add_user.sh` script is called which adds the user to the
|
|
htpasswd file.
|
|
|
|
|
|
Form configuration file: `test_server.json`
|
|
|
|
{
|
|
"title": "Test server",
|
|
"forms": {
|
|
"add_user": {
|
|
"title": "Add user",
|
|
"description": "Add a user to the htpasswd file",
|
|
"submit_title": "Add user",
|
|
"script": "job_add_user.sh",
|
|
"fields": [
|
|
{"name": "username", "title": "Username", "type": "string"},
|
|
{"name": "password1", "title": "Password", "type": "password"},
|
|
{"name": "password2", "title": "Repeat password", "type": "password"}
|
|
]
|
|
}
|
|
}
|
|
}
|
|
|
|
The script `job_add_user.sh`:
|
|
|
|
#!/bin/sh
|
|
|
|
if [ -z "$password1" ]; then
|
|
echo "Empty password specified" >&2; exit 1
|
|
fi
|
|
if [ "$password1" != "$password2" ]; then
|
|
echo "Passwords do not match" >&2; exit 1
|
|
fi
|
|
|
|
htpasswd -s -b .htpasswd $username $password1 || exit $?
|
|
|
|
echo "User created or password updated"
|
|
|
|
We can now start ScriptForm to start serving the form over HTTP:
|
|
|
|
$ scriptform -p8080 ./test_server.json
|
|
|
|
The user is presented with the following form:
|
|
|
|
|
|
|
|
When submitting the form, the results are displayed.
|
