# Webfuse API introduction
|
||||
|
||||
This introduction provides a general overview to webfuse API.
|
||||
Please refer to the [build instructions](build.md) to generate API reference documentation.
|
||||
|
||||
## Contents
|
||||
|
||||
- [Authentication](#Authentication)
|
||||
|
||||
## Authentication
|
||||
|
||||
By default, webfuse daemon will redirect each filesystem call to the first connected provider without any authentication.
|
||||
This might be good for testing purposes or when an external authentication mechanism is used. In some use cases, explicit authentication is needed. Therefore, authentication can be enabled within webfuse daemon.
|
||||
|
||||
When authentication is enabled, filesystem calls are only redirected to a connected provider, after `authenticate`
|
||||
has succeeded.
|
||||
|
||||
|
||||
|
||||
### Enable authentication
|
||||
|
||||
Authentication is enabled, if one or more authenticators are registered via `wf_server_config`.
|
||||
|
||||
static bool authenticate(struct wf_credentials * creds, void * user_data)
|
||||
{
|
||||
char const * username = wf_credentials_get(creds, "username");
|
||||
char const * password = wf_credentials_get(creds, "password");
|
||||
|
||||
return ((NULL != username) && (0 == strcmp(username, "bob")) &&
|
||||
(NULL != password) && (0 == strcmp(password, "???")));
|
||||
}
|
||||
|
||||
wf_server_config * config = wf_server_config_create();
|
||||
wf_server_config_add_authenticator(config, "username", &authenticate, NULL);
|
||||
|
||||
wf_server * server = wf_server_create(config);
|
||||
//...
|
||||
|
||||
### Authenticator types and credentidals
|
||||
|
||||
Each authenticator is identified by a user defined string, called `type`. The type is provided by the `authenticate` request, so you can define different authenticators for different authentication types, e.g. username, certificate, token.
|
||||
|
||||
Actually, only one type is used: **username**
|
||||
**It is strongly recommended to prefix custom authenticator types with an underscore (`_`) to avoid name clashes.**
|
||||
|
||||
The `wf_credentials`struct represents a map to access credentials as key-value pairs, where both, key and value, are of type string.
|
||||
|
||||
#### username
|
||||
|
||||
The authenticator type **username** is used to authenticate via username and password. Valid credentials should contain two keys.
|
||||
|
||||
- **username** refers to the name of the user
|
||||
- **password** refers to the password of the user
|
||||
|
||||
**Note** that no further encryption is done, so this authenticator type should not be used over unencrypted websocket connections.

# Build Instructions
|
||||
|
||||
To install dependencies, see below.
|
||||
|
||||
cd webfuse
|
||||
mkdir .build
|
||||
cd .build
|
||||
cmake ..
|
||||
make
|
||||
|
||||
## Build options
|
||||
|
||||
By default, unit tests are enabled. You can disable them using the following cmake options:
|
||||
|
||||
- **WITHOUT_TESTS**: disable tests
|
||||
`cmake -DWITHOUT_TESTS=ON ..`
|
||||
|
||||
Since webfuse consists of two libraries, it is possible to disable one of them
|
||||
in order to reduce build dependencies.
|
||||
*Note that unit tests are only available, when both libraries are built.*
|
||||
|
||||
- **WITHOUT_ADAPTER**: omit adapter library
|
||||
`cmake -DWITHOUT_ADAPTER=ON`
|
||||
|
||||
- **WIHTOU_PROVIDER**: omit provider library
|
||||
`cmake -DWITHOUT_PROVIDER=ON`
|
||||
|
||||
## Create API documentation
|
||||
|
||||
To create API documentation, you must install doxygen and dot first.
|
||||
After that, run doxygen in the project root directory.
|
||||
|
||||
doxygen
|
||||
|
||||
After that, you will find the API documentation in the doc/api subdirectory.
|
||||
|
||||
## Dependencies
|
||||
|
||||
- [libfuse3](https://github.com/libfuse/libfuse/)
|
||||
- [libwebsockets](https://libwebsockets.org/)
|
||||
- [Jansson](https://jansson.readthedocs.io)
|
||||
- [GoogleTest](https://github.com/google/googletest) *(optional)*
|
||||
|
||||
### Installation from source
|
||||
|
||||
#### libfuse
|
||||
|
||||
To install libfuse, meson is needed. Please refer to [meson quick guide](https://mesonbuild.com/Quick-guide.html) for setup instructions.
|
||||
|
||||
wget -O fuse-3.8.0.tar.gz https://github.com/libfuse/libfuse/archive/fuse-3.8.0.tar.gz
|
||||
tar -xf fuse-3.8.0.tar.gz
|
||||
cd libfuse-fuse-3.8.0

|
||||
There are three types of messages, used for communication between webfuse daemon and filesystem provider. All message types are encoded in [JSON](https://www.json.org/) and strongly inspired by [JSON-RPC](https://www.jsonrpc.org/).
|
||||
|
||||
### Request
|
||||
|
||||
A request is used by a sender to invoke a method on the receiver. The sender awaits a response from the receiver. Since requests and responses can be sendet or answered in any order, an id is provided in each request to identify it.
|
||||
|
||||
{
|
||||
"method": <method_name>,
|
||||
"params": <params>,
|
||||
"id" : <id>
|
||||
}
|
||||
|
||||
| Item | Data type | Description |
|
||||
| ----------- |:---------:| --------------------------------- |
|
||||
| method_name | string | name of the method to invoke |
|
||||
| params | array | method specific parameters |
|
||||
| id | integer | id, which is repeated in response |
|
||||
|
||||
### Response
|
||||
|
||||
A response is used to answer a prior request. There are two kinds of responses:
|
||||
|
||||
#### Successful Results
|
||||
|
||||
{
|
||||
"result": <result>,
|
||||
"id": <id>
|
||||
}
|
||||
|
||||
| Item | Data type | Description |
|
||||
| ----------- |:---------:| ----------------------- |
|
||||
| result | any | request specific result |
|
||||
| id | integer | id, same as request |
|
||||
|
||||
#### Error notifications
|
||||
|
||||
{
|
||||
"error": {
|
||||
"code": <code>
|
||||
},
|
||||
"id": <id>
|
||||
}
|
||||
|
||||
| Item | Data type | Description |
|
||||
| ----------- |:---------:| ------------------- |
|
||||
| code | integer | error code |
|
||||
| id | integer | id, same as request |
|
||||
|
||||
#### Error codes
|
||||
|
||||
| Symbolic name | Code | Description |
|
||||
| ------------------ | ---------:| ---------------------- |
|
||||
| GOOD | 0 | no error |
|
||||

|
||||
| BAD_ACCESS_DENIED | 102 | access not allowed |
|
||||
|
||||
### Notification
|
||||
|
||||
Notfications are used to inform a receiver about something. Unlike requests, notifications are not answered. Therefore, an id is not supplied.
|
||||
|
||||
{
|
||||
"method": <method_name>,
|
||||
"params": <params>
|
||||
