需求：Salesforce上面的文件需要实时自动存放到Github上面

如果我们需要存放到Github上面，那么我们就需要调用Github的API来进行集成

1。取得github上面的Personal access tokens

打开如下链接，取得AccessToken

 https://github.com/settings/tokens 

或者SettingsDeveloper SettingsPersonal access tokens (classic)

再点击【Generate new token】按钮。

如图所示

选择适当权限，并点击CreateToken按钮

2。创建GitHubApiIntegration方法，

public class GitHubApiIntegration {
    // Define your GitHub API endpoint
    private static final String GITHUB_API_URL = 'https://api.github.com';


    // 这里是你的GitHub personal access token，如Step1所示，取得AccessToken后，替换掉下面的字符串。
    private static final String GITHUB_ACCESS_TOKEN = 'YOUR_PERSONAL_ACCESS_TOKEN';


    public static void uploadFile(String owner, String repo, String branch, String filePath, String content, String commitMessage) {
        // Build the API URL
        String apiUrl = GITHUB_API_URL + '/repos/' + owner + '/' + repo + '/contents/' + filePath;


        // Create a JSON payload for the API request
        Map<String, Object> requestData = new Map<String, Object>{
            'message' => commitMessage,
            'content' => EncodingUtil.base64Encode(Blob.valueOf(content)),
            'branch' => branch
        };


        HttpRequest req = new HttpRequest();
        req.setEndpoint(apiUrl);
        req.setMethod('PUT');
        req.setHeader('Authorization', 'token ' + GITHUB_ACCESS_TOKEN);
        req.setHeader('Content-Type', 'application/json');
        req.setBody(JSON.serialize(requestData));


        Http http = new Http();
        HttpResponse res = http.send(req);


        if (res.getStatusCode() == 200) {
            System.debug('File uploaded successfully.');
        } else {
            //System.debug('Error uploading file: ' + res.getStatus() + ' ' + res.getStatusText());
        }
    }
}

3。Salesforce上面设置RemoteSite

4。最后是Apex代码调用GitHubApiIntegration类的方法

String owner = 'yusizhong'; // Replace with the owner's GitHub username or organization name
String repo = 'githubintegration'; // Replace with the name of the repository
String branch = 'main'; // Replace with the desired branch name
String filePath = 'new.txt'; // Replace with the path to the file you want to create or update
String content = 'Content of your file'; // Replace with the content you want to upload
String commitMessage = 'Add a new file'; // Replace with your commit message

GitHubApiIntegration.uploadFile(owner, repo, branch, filePath, content, commitMessage);

执行成功，Github生成文件效果如图所示。
