TODO: List what your package can do. Maybe include images, gifs, or videos.
|
||||
HTTP Client for Dart with Middlewares !
|
||||
|
||||
## Getting started
|
||||
|
||||
TODO: List prerequisites and provide or point to information on how to
|
||||
start using the package.
|
||||
Simply add wyatt_http_client in pubspec.yaml, then
|
||||
|
||||
```dart
|
||||
import 'package:wyatt_http_client/wyatt_http_client.dart';
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
TODO: Include short and useful examples for package users. Add longer examples
|
||||
to `/example` folder.
|
||||
Firstly you have to understand **Middleware** and **Pipeline** concepts.
|
||||
|
||||
In `wyatt_http_client` a middleware is an object where requests and responses
|
||||
pass through. And a pipeline is basicaly a list of middlewares.
|
||||
|
||||
In a pipeline with middlewares A and B, if request pass through A, then B,
|
||||
the response will pass through B then A.
|
||||
|
||||
> You can `print(pipeline)` to get full process order of a pipeline.
|
||||
|
||||
For example, if you want to log every request, and simplify an url you can use provided `SimpleLogger` and `UriPrefix` .
|
||||
|
||||
```dart
|
||||
const like = 'sample';
|
||||
// Create the Pipeline
|
||||
final Pipeline pipeline = Pipeline()
|
||||
.addMiddleware(
|
||||
UriPrefixMiddleware(
|
||||
protocol: Protocols.http,
|
||||
authority: 'localhost:80',
|
||||
),
|
||||
)
|
||||
.addMiddleware(SimpleLoggerMiddleware());
|
||||
```
|
||||
|
||||
## Additional information
|
||||
Then if you print the pipeline,
|
||||
|
||||
TODO: Tell users more about the package: where to find more information, how to
|
||||
contribute to the package, how to file issues, what response they can expect
|
||||
from the package authors, and more.
|
||||
```
|
||||
[Req] -> UriPrefix -> SimpleLogger
|
||||
[Res] -> SimpleLogger
|
||||
```
|
||||
|
||||
> The `response` doesn't pass through `UriPrefix` because it's an `OnRequestMiddleware` only.
|
||||
|
||||
And you can create a client.
|
||||
|
||||
```dart
|
||||
final client = MiddlewareClient(pipeline: pipeline);
|
||||
```
|
||||
|
||||
At this point you can use `client` like every Client from `package:http/http.dart` .
|
||||
|
||||
## Recipes
|
||||
|
||||
### Rest API with URL Authentication
|
||||
|
||||
Let's build a client for a REST API where the (bad) authentication is through the URL.
|
||||
We need some middlewares:
|
||||
|
||||
* SimpleLogger, to log every request and response (useful for debug).
|
||||
* BodyToJson, to automaticaly transform Map object to JSON.
|
||||
* UriPrefix, to simplify the build of an API Object (save protocol and API prefix).
|
||||
* UnsafeAuth, to use url based authentication.
|
||||
|
||||
Let's start by creating the Pipeline:
|
||||
|
||||
```dart
|
||||
final Pipeline pipeline = Pipeline()
|
||||
.addMiddleware(
|
||||
UriPrefixMiddleware(
|
||||
protocol: Protocols.http,
|
||||
authority: 'localhost:80',
|
||||
),
|
||||
)
|
||||
.addMiddleware(BodyToJsonMiddleware())
|
||||
.addMiddleware(
|
||||
UnsafeAuthMiddleware(
|
||||
username: 'wyatt',
|
||||
password: 'motdepasse',
|
||||
),
|
||||
)
|
||||
.addMiddleware(SimpleLoggerMiddleware());
|
||||
```
|
||||
|
||||
Then simply create a client and make a call.
|
||||
|
||||
```dart
|
||||
final client = MiddlewareClient(pipeline: pipeline);
|
||||
|
||||
await client.get(Uri.parse('/protected'));
|
||||
```
|
||||
|
||||
> Here it make a `GET` call on `http://localhost:80/protected?username=wyatt&password=motdepasse`
|
||||
|
||||
And voilà.
|
||||
|
||||
### Rest API with Oauth2
|
||||
|
||||
So now we want a real authentication.
|
||||
|
||||
```dart
|
||||
final Pipeline pipeline = Pipeline()
|
||||
.addMiddleware(
|
||||
UriPrefixMiddleware(
|
||||
protocol: Protocols.http,
|
||||
authority: 'localhost:80',
|
||||
),
|
||||
)
|
||||
.addMiddleware(BodyToJsonMiddleware())
|
||||
.addMiddleware(
|
||||
RefreshTokenAuthMiddleware(
|
||||
authorizationEndpoint: '/auth/sign-in',
|
||||
tokenEndpoint: '/auth/refresh',
|
||||
accessTokenParser: (body) => body['access_token']! as String,
|
||||
refreshTokenParser: (body) => body['refresh_token']! as String,
|
||||
unauthorized: HttpStatus.forbidden,
|
||||
),
|
||||
)
|
||||
.addMiddleware(SimpleLoggerMiddleware());
|
||||
```
|
||||
|
||||
> Here we just change `UnsafeAuthMiddleware` by `RefreshTokenAuthMiddleware` and the whole app while adapt to a new authentication system.
|
||||
|
||||
### Create a new Middleware
|
||||
|
||||
You can create your own middleware by implementing `Middleware` class, and use mixins to add `OnRequest` and/or `OnResponse` methods.
|
||||
|
||||
```dart
|
||||
class SimpleLoggerMiddleware
|
||||
with OnRequestMiddleware, OnResponseMiddleware
|
||||
implements Middleware {
|
||||
|
||||
@override
|
||||
String getName() => 'SimpleLogger';
|
||||
|
||||
@override
|
||||
Future<MiddlewareRequest> onRequest(
|
||||
MiddlewareContext context,
|
||||
MiddlewareRequest request,
|
||||
) async {
|
||||
print('${getName()}::OnRequest');
|
||||
return request;
|
||||
}
|
||||
|
||||
@override
|
||||
Future<MiddlewareResponse> onResponse(
|
||||
MiddlewareContext context,
|
||||
MiddlewareResponse response,
|
||||
) async {
|
||||
print('${getName()}::OnResponse');
|
||||
return response;
|
||||
}
|
||||
}
|
||||
```
