oauth flow with spring boot

hello ,

I'm trying to integrate Dropbox with my Spring Boot application and enable the OAuth flow so users can use their Dropbox accounts within my application. However, it isn't working, and I'm struggling with the documentation. Can someone help me?

Thank you!

Hi @Zahra1,

Did you try the workflow here? 🧐 If not, give it a try.

If something is still confusing you, share some more details. 😉

Good luck.

@Zahra1 For more information on how the authorization process works, please refer to the following resources:

While Dropbox can't offer help with Spring Boot itself, as that's not made by Dropbox, we're happy to help with any issues on the Dropbox side. If you're seeing any issues with the Dropbox functionality, feel free to share the details so we can take a look.

i've tried this :

import com.dropbox.core.DbxRequestConfig;
import com.dropbox.core.v2.DbxClientV2;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Service;

@Service
public class DropboxService {


@Value("${dropbox.app.key}")
private String appKey;

@Value("${dropbox.app.secret}")
private String appSecret;

public DbxClientV2 getClient(String accessToken) {
DbxRequestConfig config = new DbxRequestConfig("APPFEATURE");
return new DbxClientV2(config, accessToken);
    }
}


@Controller
public class DropboxController {

@Value("${dropbox.appKey}")
private String DROPBOX_APP_KEY;

@Value("${dropbox.appSecret}")
private String DROPBOX_APP_SECRET;

@Value("${dropbox.redirect.uri}")
private String DROPBOX_REDIRECT_URI;

private DbxWebAuth webAuth;

@GetMapping("/dropbox/auth")
public RedirectView authenticate() {
DbxRequestConfig config = DbxRequestConfig.newBuilder("dropbox/spring-boot-app").build();
DbxAppInfo appInfo = new DbxAppInfo(DROPBOX_APP_KEY, DROPBOX_APP_SECRET);
webAuth = new DbxWebAuth(config, appInfo);

DbxWebAuth.Request webAuthRequest = DbxWebAuth.newRequestBuilder()
                .withRedirectUri(DROPBOX_REDIRECT_URI, new DbxStandardHttpRequestor.Config() )  //DbxStandardHttpRequestor.Config()
                .build();

String authorizeUrl = webAuth.authorize(webAuthRequest);
return new RedirectView(authorizeUrl);
    }

@GetMapping("/dropbox/callback")
public String callback(@RequestParam String code) {
try {
DbxAuthFinish authFinish = webAuth.finishFromCode(code);
String accessToken = authFinish.getAccessToken();

// Use the access token to create a DbxClientV2 instance
            DbxRequestConfig config = DbxRequestConfig.newBuilder("dropbox/spring-boot-app").build();
DbxClientV2 client = new DbxClientV2(config, accessToken);

// Get the current account info as an example
            FullAccount account = client.users().getCurrentAccount();
System.out.println("Account name: " + account.getName().getDisplayName());

return "redirect:/success";
        } catch (DbxException ex) {
ex.printStackTrace();
return "redirect:/error";
        }
    }
}

Cannot resolve symbol 'DbxStandardHttpRequestor'

Hm... Why do you think that such a class should be there at all? Where you saw documentation about such an usage? 🤔

Just take a look on some of the examples and follow the idea there. 😉

By the way... you are using short lived token only! Keep in mind that for long term access you would need refresh token too if you need long term access.

@Zahra1 Здравко is correct; the Dropbox Java SDK does not define a 'DbxStandardHttpRequestor' class. Perhaps you meant 'StandardHttpRequestor'? The withRedirectUri method takes a String and DbxSessionStore anyway though, not an HttpRequestor.

In any case, check out the examples folder for examples of using the Java SDK functionality.
