流程分析
Web網(wǎng)站的授權(quán)流程如下
image.png
引導(dǎo)授權(quán)用戶
引導(dǎo)需要授權(quán)的用戶到如下地址
https://api.weibo.com/oauth2/authorize?client_id=YOUR_CLIENT_ID&response_type=code&redirect_uri=YOUR_REGISTERED_REDIRECT_URI
<a >
<span>微博</span>
</a>
image.png
用戶授權(quán)
來到授權(quán)地址后歉备，需要用戶授權(quán)常摧，授權(quán)成功返回Code碼
image.png
授權(quán)成功
如果用戶同意授權(quán)，頁面跳轉(zhuǎn)至回調(diào)地址并攜帶Code碼

換取Access Token
通過授權(quán)返回的CODE威创，請求如下地址落午，換取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
得到如下響應(yīng)結(jié)果
body: {"access_token":"2.00123456789480Ngwx8","remind_in":"15896999","expires_in":157679999,"uid":"12345678","isRealName":"true"}
HTTP客戶端
Code獲取后肚豺，需要使用Code獲取Access Token溃斋，以及使用token請求其他接口，此時需要使用發(fā)送請求的HTTP客戶端吸申，這里使用hutool工具類
發(fā)送一個POST請求示例：
//鏈?zhǔn)綐?gòu)建請求
String result2 = HttpRequest.post(url)
.header(Header.USER_AGENT, "Hutool http")//頭信息梗劫，多個頭信息多次調(diào)用此方法即可
.form(paramMap)//表單內(nèi)容
.timeout(20000)//超時，毫秒
.execute().body();
Console.log(result2);
使用Access Token請求相關(guān)接口
Access Token得到后截碴，就可以使用Access Token請求相關(guān)接口獲取對應(yīng)數(shù)據(jù)梳侨，這里使用2個接口舉例使用說明。
相關(guān)接口如下：

根據(jù)用戶ID獲取用戶信息
根據(jù)用戶ID獲取用戶信息接口描述信息如下
image.png
只需要如下設(shè)置請求參數(shù)日丹，請求地址即可獲取用戶信息
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();
響應(yīng)如下類似信息
{

"idstr": "58812345464100",
"class": 1,
"screen_name": "XX",

"domain": "",

}
獲取用戶的粉絲列表
獲取用戶的粉絲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();
響應(yīng)結(jié)果
粉絲信息: {"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集成微博登錄
添加依賴
添加hutool開發(fā)工具包丙躏，核心用于發(fā)送Http請求择示。

封裝Token等信息
用戶授權(quán)成功后，使用WeiboUser類封裝相關(guān)信息
/**
* 封裝登錄認(rèn)證后的令牌等信息
*/
@Data
public class WeiboUser {
/**
* 令牌
*/
private String access_token;
/**
* 令牌過期時間,該參數(shù)即將廢棄
*/
private String remind_in;
/**
* 令牌過期時間,單位是秒數(shù)
*/
private long expires_in;
/**
* 該社交用戶的唯一標(biāo)識
*/
private String uid;
/**
* 是否記住我
*/
private String isRealName;
}
