springboot第三方微信登录（Boot集成第三方登录之微博登录）
微博开放平台：https://open.weibo.com/
网站接入登陆微博开放平台，进入微连接，选择网站接入
点击立即接入
填写开发者信息与身份认证信息
开发者信息认证通过后即可创建应用。
应用创建成功后会得到app key和app secret
在应用信息的高级信息中设置授权回调地址
添加测试账号，这里使用开发者账号测试。
Web网站的授权流程如下
引导需要授权的用户到如下地址
https://api.weibo.com/oauth2/authorize?client_id=YOUR_CLIENT_ID&response_type=code&redirect_uri=YOUR_REGISTERED_REDIRECT_URI
复制代码
<a href="https://api.weibo.com/oauth2/authorize?client_id=123456789&response_type=code&redirect_uri=https://ws20264753.zicp.fun/weibo/success">
<span>微博</span>
</a>
复制代码
来到授权地址后，需要用户授权，授权成功返回Code码
如果用户同意授权，页面跳转至回调地址并携带Code码
通过授权返回的CODE，请求如下地址，换取Access Token。
https://api.weibo.com/oauth2/access_token?client_id=YOUR_CLIENT_ID&client_secret=YOUR_CLIENT_SECRET&grant_type=authorization_code&redirect_uri=YOUR_REGISTERED_REDIRECT_URI&code=CODE
复制代码
https://api.weibo.com/oauth2/access_token?code=0c55753fe19a5bcf0a4a42afd4a64353&grant_type=authorization_code&client_secret=81abcdefghijkmllb4a45f4288ef&redirect_uri=https://ws20264753.zicp.fun/weibo/success&client_id=231234566
复制代码
得到如下响应结果
body: {"access_token":"2.00123456789480Ngwx8","remind_in":"15896999","expires_in":157679999,"uid":"12345678","isRealName":"true"}
复制代码
Code获取后，需要使用Code获取Access Token，以及使用token请求其他接口，此时需要使用发送请求的HTTP客户端，这里使用hutool工具类
发送一个POST请求示例：
//链式构建请求
String result2 = HttpRequest.post(url)
.header(Header.USER_AGENT, "Hutool http")//头信息，多个头信息多次调用此方法即可
.form(paramMap)//表单内容
.timeout(20000)//超时，毫秒
.execute().body();
Console.log(result2);
复制代码
Access Token得到后，就可以使用Access Token请求相关接口获取对应数据，这里使用2个接口举例使用说明。
相关接口如下：
根据用户ID获取用户信息接口描述信息如下
只需要如下设置请求参数，请求地址即可获取用户信息
Map<String, Object> selectUserParam = new HashMap<>();
selectUserParam.put("access_token", "token");
selectUserParam.put("uid", "uid");
HttpResponse execute = HttpRequest.get("https://api.weibo.com/2/users/show.json").form(selectUserParam).timeout(2000).execute();
复制代码
响应如下类似信息
{
"id": 51234100,
"idstr": "58812345464100",
"class": 1,
"screen_name": "XX",
"name": "XX",
"province": "51",
"city": "14",
"location": "四川 成都",
"description": "真正的强者，不是流泪的人，而是含泪奔跑的人。",
"url": "",
"profile_image_url": "https://tva3.sinaimg.cn/crop.0.0.996.996.50/006qils8jw8f2cztnnp6vj30ro0rpgnj.jpg?KID=imgbed,tva&Expires=1663398489&ssig=JM0ZTUEYbs",
"light_ring": false,
"cover_image_phone": "http://ww1.sinaimg.cn/crop.0.0.640.640.640/549d0121tw1egm1kjly3jj20hs0hsq4f.jpg",
"profile_url": "u/58812345464100",
"domain": "",
"weihao": "",
"gender": "m",
}
复制代码
获取用户的粉丝列表接口描述信息如下
Map<String, Object> selectUserParam = new HashMap<>();
selectUserParam.put("access_token", weiboUser.getAccess_token());
selectUserParam.put("uid", weiboUser.getUid());
HttpResponse execute = HttpRequest.get("https://api.weibo.com/2/friendships/followers.json").form(selectUserParam).timeout(2000).execute();
复制代码
响应结果
粉丝信息: {"users":[],"has_filtered_attentions":false,"next_cursor":600,"previous_cursor":0,"total_number":1789,"use_sink_stragety":false,"has_filtered_fans":true,"use_status_strategy":false,"show_related_topic":false,"display_total_number":1789,"display_total_number_str":"1789","show_unread":false}
复制代码
添加hutool开发工具包，核心用于发送Http请求。
<dependency>
<groupId>cn.hutool</groupId>
<artifactId>hutool-all</artifactId>
<version>5.8.2</version>
</dependency>
<!-- thymeleaf页面 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
复制代码
用户授权成功后，使用WeiboUser类封装相关信息
/**
* 封装登录认证后的令牌等信息
*/
@Data
public class WeiboUser {
/**
* 令牌
*/
private String access_token;
/**
* 令牌过期时间,该参数即将废弃
*/
private String remind_in;
/**
* 令牌过期时间,单位是秒数
*/
private long expires_in;
/**
* 该社交用户的唯一标识
*/
private String uid;
/**
* 是否记住我
*/
private String isRealName;
}
