推特API（Twitter API）V2 用户关注、推文相关_twitter api v2

        前面章节已经介绍使用code换取Token的整个流程了，这里不再重复阐述了，下面我们获取到用户token以后如何帮用户自动关注别人。需要参数关注者的用户ID（token授权用户）以及关注的目标用户ID。用户ID如何获取可以看上一章节获取用户信息里面就有用户ID参数。

1.引入相关依赖Maven

<dependency>
    <groupId>oauth.signpost</groupId>
    <artifactId>signpost-core</artifactId>
    <version>1.2.1.2</version>
</dependency>
 
<dependency>
    <groupId>oauth.signpost</groupId>
    <artifactId>signpost-commonshttp4</artifactId>
    <version>1.2.1.2</version>
</dependency>
 
<dependency>
    <groupId>com.twitter</groupId>
    <artifactId>twitter-api-java-sdk</artifactId>
    <version>1.1.4</version>
</dependency>
 
<dependency>
    <groupId>commons-httpclient</groupId>
    <artifactId>commons-httpclient</artifactId>
    <version>3.1</version>
</dependency><dependency>
    <groupId>com.google.guava</groupId>
    <artifactId>guava</artifactId>
    <version>29.0-jre</version>
</dependency>

2.相关的配置类

/**
 * 推特相关配置
 */
public class TwitterConfig {
 
    /**
     * 客户id和客户私钥
     */
    public static final String CLIENT_ID = "c3dqY111tjbnFPNDM6MTpjaQ";
    public static final String CLIENT_SECRET = "kf1119fmdeXZHpOV-fjv9umx55ZdccCkNONjea";
 
 
    /**
     * 应用KYE和私钥
     */
    public static final String CONSUMER_KEY = "lhyfiD111MffGeHMR";
    public static final String CONSUMER_SECRET = "BRNxnV5Lx111jtptduIkcwjB";
 
    /**
     * 应用的TOKEN
     */
    public static final String ACCESS_TOKEN = "14821111633-A8xyN5111FgkbStu";
    public static final String ACCESS_TOKEN_SECRET = "oZaKBphpoo111SZvzoXPAQ";
 
        /**
     * 用户 Bearer Token
     */
    public static final String BEARER_TOKEN = "AAAAAAAAAAAAAAAAAAAAAOwXswEAAAAAGLQE%2F%2BydboYofYWIsXeXYz%2FvwOM%3Dxyxysp8mTiT8j6feRoc0BshFaghbkC58VHMRtcdvo5WjkvyqKF";
 
}

3.根据用户token让用户关注开发者 

@Data
@Accessors(chain = true)
public class AttentionDto {
 
    /**
     * true 表示关注成功  false 表示关注失败（目标用户没有公开推文的情况，因为他们必须批准关注者请求）
     */
    private Boolean following;
 
    /**
     * 指示目标用户是否需要批准关注请求。请注意，只有当目标用户批准传入的关注者请求时，经过身份验证的用户才会关注目标用户  false就是正常的
     */
    private Boolean pending_follow;
 
}

  /**
     * 用户关注
     * @param token 授权换取的用户token
     * @param userId 用户自己的ID
     * @return
     * @throws Exception
     */
    public AttentionDto attention(String token, String userId) throws Exception {
        String urlAdress = "https://api.twitter.com/2/users/" + userId + "/following";
        URL url12 = new URL(urlAdress);
        HttpURLConnection connection = (HttpURLConnection) url12.openConnection();
        connection.setRequestMethod("POST");
        connection.setRequestProperty("Content-Type", "application/json");
        connection.setRequestProperty("Authorization", "Bearer " + token);
        JSONObject requestBody = new JSONObject();
        //需要关注的用户ID
        requestBody.put("target_user_id", "148294855969111111");
        String requestBodyString = requestBody.toString();
        connection.setDoOutput(true);
        OutputStream outputStream = connection.getOutputStream();
        outputStream.write(requestBodyString.getBytes());
        outputStream.flush();
        outputStream.close();
 
        int responseCode = connection.getResponseCode();
        InputStream inputStream;
        if (responseCode >= 200 && responseCode < 400) {
            inputStream = connection.getInputStream();
        } else {
            inputStream = connection.getErrorStream();
        }
 
        BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
        String line;
        StringBuilder responseBuilder = new StringBuilder();
        while ((line = reader.readLine()) != null) {
            responseBuilder.append(line);
        }
        reader.close();
        String response = responseBuilder.toString();
        if(JSON.parseObject(response).get("data") != null){
            JSONObject json = JSON.parseObject(JSON.parseObject(response).get("data").toString());
            AttentionDto attentionDto = new AttentionDto();
            Object ret = json.get("following");
            attentionDto.setFollowing(Boolean.parseBoolean(ret == null ? "false" : ret.toString()));
            ret = json.get("pending_follow");
            attentionDto.setPending_follow(Boolean.parseBoolean(ret == null ? "false" : ret.toString()));
            return attentionDto;
        }
        return null;
    }

4.查询我的推文列表

 /**
     * 查询我的推文列表
     * @param tweetUserId
     * @param token
     * @param ttTweetsId  平台指定转推文的ID
     * @param maxResults = 5-10之间
     * @return
     */
    public Integer getTweetList(String tweetUserId,String token,Integer maxResults,String ttTweetsId){
        try {
            String httpUrl = "https://api.twitter.com/2/users/"+ tweetUserId + "/tweets?max_results="+maxResults;
            httpUrl += "&expansions=author_id,edit_history_tweet_ids,referenced_tweets.id&tweet.fields=created_at";
            // 只查用户当日的推文
            Instant currentTime = LocalDateTime.of(LocalDate.now(), LocalTime.MIN).toInstant(ZoneOffset.of("+8"));
            DateTimeFormatter formatter = DateTimeFormatter.ISO_INSTANT;
            String endTimeRFC3339 = formatter.format(currentTime);
            httpUrl += "&start_time="+endTimeRFC3339;
                // 构建请求 URL
            URL url = new URL(httpUrl);
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            // 设置请求方法和请求头
            connection.setRequestMethod("GET");
            connection.setRequestProperty("Authorization", "Bearer " + token);
            // 发送请求
            int responseCode = connection.getResponseCode();
            Assert.isTrue(responseCode == HttpURLConnection.HTTP_OK, "get tweet error");
            Integer numer = 0;
            // 读取响应
            BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
            String line;
            StringBuilder response = new StringBuilder();
            while ((line = reader.readLine()) != null) {
                response.append(line);
            }
            reader.close();
            JSONObject jsonObject = JSON.parseObject(response.toString());
            JSONArray jsonArray = (JSONArray) jsonObject.get("data");
            if(jsonArray == null){
                return numer;
            }
            for (int i = 0; i < jsonArray.size(); i++) {
                JSONObject json = jsonArray.getJSONObject(i);
                JSONArray referencedTweets = json.getJSONArray("referenced_tweets");
                if(referencedTweets != null){
                        /*retweeted: 表示当前推文是转推（Retweet）的引用。
                        quoted: 表示当前推文是引用推文（Quote Tweet）的引用。
                        replied_to: 表示当前推文是回复（Reply）的引用。*/
                    //上个推文的id
                    String type = referencedTweets.getJSONObject(0).get("type").toString();
                    String id = referencedTweets.getJSONObject(0).get("id").toString();
                    if(type.equals("quoted") || type.equals("retweeted") && ttTweetsId.equals(id)){
                        //quoted 表示推文是引用
                        numer++;
                    }
                }
            }
            // 打印响应
            return numer;
        } catch (IOException e) {
            e.printStackTrace();
        }
        return 0;
    }

5.查询那些用户进行了推文的转发

/**
     * 根据推文ID查询那些用户进行了转发
     * @param tweetId
     * @param token
     * @return
     */
    public String transmitUserList(String tweetId,String token){
        try {
            // 构建请求 URL
            URL url = new URL("https://api.twitter.com/2/tweets/"+tweetId+"/retweeted_by");
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            // 设置请求方法和请求头
            connection.setRequestMethod("GET");
            connection.setRequestProperty("Authorization", "Bearer " + token);
 
            // 发送请求
            int responseCode = connection.getResponseCode();
            if (responseCode == HttpURLConnection.HTTP_OK) {
                // 读取响应
                BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
                String line;
                StringBuilder response = new StringBuilder();
                while ((line = reader.readLine()) != null) {
                    response.append(line);
                }
                reader.close();
                // 打印响应
                return response.toString();
            } else {
                System.out.println("Failed to fetch data from Twitter API. Response code: " + responseCode);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
        return null;
    }

6.生成推文的访问链接

    /**
     * 生成推文转发链接
     * @param tweetsName   推特用户名   如：@123456
     * @param tweetsId     推文Id
     * @return
     */
    public String getTtTweetsUrl(String tweetsName,String tweetsId){
        //推文Id
        String url = "https://twitter.com/";
        //推特用户名
        url += tweetsName;
        url += "/status/" + tweetsId +"?s=20";
        return url;
    }

7.可以获取开发者的账号Bearer Token

/**
     * 获取开发者推特token
     * @return
     */
    public String getTwitterToken(){
        try {
            String consumerKey = URLEncoder.encode(TwitterConfig.CONSUMER_KEY, "UTF-8");
            String consumerSecret = URLEncoder.encode(TwitterConfig.CONSUMER_SECRET, "UTF-8");
            String credentials = consumerKey + ":" + consumerSecret;
            String base64Credentials = Base64.getEncoder().encodeToString(credentials.getBytes());
            //authorization_code、refresh_token、client_credentials
            String grantType = "client_credentials";
            URL url = new URL("https://api.twitter.com/oauth2/token");
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setRequestMethod("POST");
            connection.setRequestProperty("Authorization", "Basic " + base64Credentials);
            connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded;charset=UTF-8");
            connection.setDoOutput(true);
            connection.setDoInput(true);
            String data = "grant_type=" + grantType +
                "&client_id="+TwitterConfig.CLIENT_ID+"&client_secret="+TwitterConfig.CLIENT_SECRET+"&code_verifier=challenge";
            connection.getOutputStream().write(data.getBytes("UTF-8"));
 
            BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
            StringBuilder response = new StringBuilder();
            String line;
            while ((line = reader.readLine()) != null) {
                response.append(line);
            }
            reader.close();
 
            // Extract bearer token from JSON response
            String jsonResponse = response.toString();
            JSONObject json = JSON.parseObject(jsonResponse);
            return json.get("access_token").toString();
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }
