+# url-shortener
+
+A simple short URL generator, written in kotlin.
+
+## 1. API
+
+### 1.1 Create new URL
+
+> POST /manage
+
+Create a new short URL. Accepts content-type `application/x-www-form-urlencoded`.
+
+Body should contain one parameter, `url`, the desired URL to be shortened.
+
+Returns `application/json`, format:
+
+```json
+{
+    "err" : 0,
+    "data" : {
+        "id" : "<Long>: ID of short URL",
+        "uuid" : "<String>: 22 character unique string"
+    }
+}
+```
+
+This API requires authentication.
+
+### 1.2 Get all URL
+
+> GET /manage
+
+Return a list of all URLs you've created.
+
+Returns `application/json`, format:
+
+```json
+{
+    "err" : 0,
+    "data" : [
+        {
+            "id" : "<Long>: ID of short URL",
+            "uuid" : "<String>: 22 character unique string",
+            "url" : "<String>: The exact URL to be redirected to"
+        },
+        {
+            "..." : "..."
+        },
+        "..."
+    ]
+}
+```
+
+This API requires authentication.
+
+### 1.3 Delete URL
+
+> DELETE /manage/{id}
+
+Delete a URL with the given ID.
+
+This API requires authentication.
+
+### 1.4 Using short URL
+
+> GET /{uuid}
+
+If the given UUID is valid, server will return a `302 Found`, and your browser will redirect you to the corresponding real URL.
+
+Otherwise you'll get a `404 Not Found`.
+
+## 2. Authentication
+
+Managing short URLs requires authentication.
+
+Simply specify `x-auth-id` and `x-auth-token` in HTTP header.
+
+You should manually add users in the `auth` table.
+
+## 3. Build
+
+This project provides a Gradle wrapper, so it's easy to build.
+
+Be sure to configure your MySQL database and edit the `application.properties` file before running.
