# xdrm go framework
|
||||
# Articles API
|
||||
|
||||
### 1. Download and build the package
|
||||
This repository showcases the use of the [aicra](https://git.xdrm.io/go/aicra) API engine.
|
||||
|
||||
### 1. download and build the package
|
||||
|
||||
```bash
|
||||
go get -u git.xdrm.io/go/tiny-url-ex
|
||||
go get -u git.xdrm.io/go/articles-api
|
||||
```
|
||||
|
||||
### 2. launch in docker
|
||||
|
||||
Build the image.
|
||||
Build the image :
|
||||
```bash
|
||||
$ docker build -t tiny-url .
|
||||
$ docker build -t articles-api .
|
||||
```
|
||||
|
||||
Then you can run the container with :
|
||||
Run the container :
|
||||
```bash
|
||||
$ docker run -p 127.0.0.1:8888:4242 tiny-url
|
||||
$ docker run -p 127.0.0.1:8888:4242 articles-api
|
||||
```
|
||||
|
||||
You can now play with it with any regular REST API client at `127.0.0.1:8888`.
|
||||
|
||||
##### 1. Get an authentication token
|
||||
#### 2. Play with it
|
||||
|
||||
- `POST /token/admin` to get an authentication token.
|
||||
The [api.json](./api.json) configuration file defines what this api provides, refer to it to know what requests are available.
|
||||
|
||||
#### 2. Manage tiny urls
|
||||
|
||||
> The authentication token must be set inside the `Authorization` header of each request except for the `GET` method which does not require you to be authenticated.
|
||||
|
||||
- `POST /<some-url>` to set a new tiny-url for the url `<some-url>` to redirect to the FORM variable named `target`. Also you can send the FORM data as _x-www-form-urlencoded_, _form-data_ or _json_.
|
||||
- `PUT /<some-url>` to update an existing tiny-url for the url `<some-url>` to redirect to the FORM variable named `target`.
|
||||
- `DELETE /<some-url>` to delete the tiny-url for `<some-url>`.
|
||||
- `GET /<some-url>` to redirect to the target of an existing url `<some-url>`.
|
||||
Examples :
|
||||
- `GET /user/12` returns information about the user identified with 12.
|
||||
- `POST /article` given required parameters creates a new article.
