`JustAuth`, as you see, It is just a Java library of third-party authorized login, It's smaller and easier to use. JustAuth is the best third-party login tool written in JAVA.

Source Code：[gitee](https://gitee.com/yadong.zhang/JustAuth) | [github](https://github.com/zhangyd-c/JustAuth)    
Docs：[Reference Doc](https://www.justauth.cn)

## Features

1. **Multiple platform**: Has integrated more than a dozen third-party platforms.([plan](https://gitee.com/yadong.zhang/JustAuth/issues/IUGRK))
2. **Minimalist**: The minimalist design is very simple to use.

## Quick start

### Add maven dependency

- Add JustAuth dependency

These artifacts are available from Maven Central:
```xml
<dependency>
    <groupId>me.zhyd.oauth</groupId>
    <artifactId>JustAuth</artifactId>
  <version>{latest-version}</version>
</dependency>
```

> **latest-version** ：
> - CURRENT: ![](https://img.shields.io/github/v/release/justauth/JustAuth?style=flat-square)
> - SNAPSHOT: ![](https://img.shields.io/nexus/s/https/oss.sonatype.org/me.zhyd.oauth/JustAuth.svg?style=flat-square)


- Add http dependency（Only need one）
  
> If there is already in the project, please ignore it. In addition, you need to pay special attention. If the low version of the dependency has been introduced in the project, please exclude the low version of the dependency first, and then introduce the high version or the latest version of the dependency

- hutool-http

  ```xml
  <dependency>
      <groupId>cn.hutool</groupId>
      <artifactId>hutool-http</artifactId>
      <version>5.2.5</version>
  </dependency>
  ```

- httpclient

  ```xml
  <dependency>
  	<groupId>org.apache.httpcomponents</groupId>
    	<artifactId>httpclient</artifactId>
    	<version>4.5.12</version>
  </dependency>
  ```

- okhttp

  ```xml
  <dependency>
    <groupId>com.squareup.okhttp3</groupId>
    <artifactId>okhttp</artifactId>
    <version>4.4.1</version>
  </dependency>
  ```


### Using JustAuth API

#### Simple

```java
// Create authorization request
AuthRequest authRequest = new AuthGiteeRequest(AuthConfig.builder()
        .clientId("clientId")
        .clientSecret("clientSecret")
        .redirectUri("redirectUri")
        .build());
// Generate authorization page url
authRequest.authorize("state");
// Get token and userinfo
authRequest.login(callback);
```

#### Builder 1. Use unchanging `AuthConfig`

```java
// Create authorization request
AuthRequest authRequest = AuthRequestBuilder.builder()
    .source("github")
    .authConfig(AuthConfig.builder()
        .clientId("clientId")
        .clientSecret("clientSecret")
        .redirectUri("redirectUri")
        .build())
    .build();
```

#### Builder 2. Use dynamic `AuthConfig`

```java
// Create authorization request
AuthRequest authRequest = AuthRequestBuilder.builder()
    .source("gitee")
    .authConfig((source) -> {
        // Use source to dynamically get AuthConfig
        // Here you can flexibly take the configuration from sql or take the configuration from the configuration file
        return AuthConfig.builder()
            .clientId("clientId")
            .clientSecret("clientSecret")
            .redirectUri("redirectUri")
            .build();
    })
    .build();
```

#### Builder 3. Support custom platform

```java
AuthRequest authRequest = AuthRequestBuilder.builder()
    // Key point: configure the custom implementation of AuthSource
    .extendSource(AuthExtendSource.values())
    // Enum name in AuthExtendSource
    .source("other")
    // ... Do other things
    .build();
```
