Dropbox的连接器

我正在为Dropbox开发一个连接器。我必须手动将URL输入到由程序生成的浏览器中,并且单击允许按钮也是手动的。请帮我弄清楚如何自动执行此操作;不应该打开浏览器,只需要一次用户交互。

这是我的代码:

import com.dropbox.core.*;
import java.io.*;
import java.util.Locale;

public class Main {
  public static void main(String[] args) throws IOException, DbxException {
    // Get your app key and secret from the Dropbox developers website.
    final String APP_KEY = "; //redacted
    final String APP_SECRET = ""; //redacted

    DbxAppInfo appInfo = new DbxAppInfo(APP_KEY, APP_SECRET);

    DbxRequestConfig config = new DbxRequestConfig("JavaTutorial/1.0",
                Locale.getDefault().toString());
    DbxWebAuthNoRedirect webAuth = new DbxWebAuthNoRedirect(config, appInfo);

    // Have the user sign in and authorize your app.
    String authorizeUrl = webAuth.start();
    System.out.println("1. Go to: " + authorizeUrl);
    System.out.println("2. Click \"Allow\" (you might have to log in first)");
    System.out.println("3. Copy the authorization code.");
    String code = new BufferedReader(new  InputStreamReader(System.in)).readLine().trim();

    // This will fail if the user enters an invalid authorization code.
    DbxAuthFinish authFinish = webAuth.finish(code);
    String accessToken = authFinish.accessToken;

    DbxClient client = new DbxClient(config, accessToken);

    System.out.println("Linked account: " + client.getAccountInfo().displayName);

    File inputFile = new File("working-draft.txt");
    FileInputStream inputStream = new FileInputStream(inputFile);
    try {
      DbxEntry.File uploadedFile = client.uploadFile("/magnum-opus.txt",
                    DbxWriteMode.add(), inputFile.length(), inputStream);
      System.out.println("Uploaded: " + uploadedFile.toString());
    } finally {
      inputStream.close();
    }

    DbxEntry.WithChildren listing = client.getMetadataWithChildren("/");
    System.out.println("Files in the root path:");
    for (DbxEntry child : listing.children) {
      System.out.println("  " + child.name + ": " + child.toString());
    }

    FileOutputStream outputStream = new FileOutputStream("magnum-opus.txt");
    try {
      DbxEntry.File downloadedFile = client.getFile("/magnum-opus.txt", null,
                    outputStream);
      System.out.println("Metadata: " + downloadedFile.toString());
    } finally {
      outputStream.close();
    }
  }
}

用户授权应用的唯一方法是通过浏览器中的OAuth进行授权。因此,在用户首次授权您的应用时,您将无法避免打开浏览器。 (在初始身份验证之后,您可以存储和重用访问令牌,但是第一次运行应用程序时,他们必须在浏览器中登录Dropbox。)

OAuth需要两个步骤。 您必须先使用DropBox注册您的应用程序。 Box将为您提供一个字符串,您应该在用户授权期间将其包含在您的通话中。

如果用户授权您的应用程序使用他们的资源,那么他们会给您一个令牌,您将来必须使用该令牌。
