准备工作

网站接入

登陆微博开放平台,进入微连接,选择网站接入 image.png 点击立即接入 image.png

开发者信息认证

填写开发者信息与身份认证信息 image.png

创建应用

开发者信息认证通过后即可创建应用。 image.png

应用创建成功后会得到app keyapp secret

image.png 在应用信息的高级信息中设置授权回调地址 image.png 添加测试账号,这里使用开发者账号测试。 image.png

流程分析

Web网站的授权流程如下 image.png

引导授权用户

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
 <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>
image.png

用户授权

来到授权地址后,需要用户授权,授权成功返回Code码

image.png

授权成功

如果用户同意授权,页面跳转至回调地址并携带Code

换取Access Token

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
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

得到如下响应结果

body: {"access_token":"2.00123456789480Ngwx8","remind_in":"15896999","expires_in":157679999,"uid":"12345678","isRealName":"true"}

HTTP客户端
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);

使用Access Token请求相关接口

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:

image.png

根据用户ID获取用户信息

根据用户ID获取用户信息接口描述信息如下 image.png

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();

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",
}

获取用户的粉丝列表

获取用户的粉丝列表接口描述信息如下 image.png
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();

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}

Spring Boot集成微博登录

添加依赖

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>

封装Token等信息

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;
}

创建Login页面

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<div>
    <a href="https://api.weibo.com/oauth2/authorize?client_id=23123456556&response_type=code&redirect_uri=https://ws20264753.zicp.fun/weibo/success">
        <span>微博</span>
    </a>
</div>
</body>
</html>

创建Home页面

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
  <div>
    <h3>登录成功</h3>
  </div>
</body>
</html>
