API v2 get_current_user error

Eugene G.4

Hi.

i've bumped into this issue migrating from v1 to v2:

after getting the auth code from this endpoint:

https://www.dropbox.com/oauth2/authorize

and getting the token from this endpoint:
https://api.dropbox.com/oauth2/token

i am trying to get user's display name. as far as i understand you've changed user endpoint to this one:

https://api.dropboxapi.com/2/users/get_current_account

but all i get from api is this:

{protocol=http/1.1, code=400, message=Bad Request, url=https://api.dropboxapi.com/2/users/get_current_account}

The same code works fine with api v1. Please give me hints if you have any.

Can you post the full response body? It should have a more useful error message.

Eugene G.4

there's nothing in response body, only this message:

Response{protocol=http/1.1, code=400, message=Bad Request, url=https://api.dropboxapi.com/2/users/get_current_account}

response headers:

0 = "Server"
1 = "nginx"
2 = "Date"
3 = "Fri, 26 Aug 2016 10:10:19 GMT"
4 = "Content-Type"
5 = "text/plain; charset=utf-8"
6 = "Content-Length"
7 = "163"
8 = "Connection"
9 = "keep-alive"
10 = "Content-Disposition"
11 = "attachment; filename=unspecified"
12 = "Content-Security-Policy"
13 = "sandbox"
14 = "Vary"
15 = "Dropbox-API-Arg, Authorization"
16 = "X-Content-Security-Policy"
17 = "sandbox"
18 = "X-Dropbox-Request-Id"
19 = "fabc4a62296d3264878e3fb2af1224eb"
20 = "X-Webkit-Csp"
21 = "sandbox"
22 = "OkHttp-Sent-Millis"
23 = "1472206218027"
24 = "OkHttp-Received-Millis"
25 = "1472206218482"

i hope it helps

"there's nothing in response body"

This is very unlikely to be true. I don't think the Dropbox API ever returns a 400 response without a response body explaining the issue.

Can you share the code you're using to read the response body?

Steve M.

In fact, this header indicates there's a 163-byte response. You'll need to read that response to see what the error is.

6 = "Content-Length"
7 = "163"

Here's my code:

private static final String DROPBOX_TOKEN_ENDPOINT = "https://api.dropbox.com/oauth2/token";
private static final String DROPBOX_ACCOUNT_INFO_ENDPOINT = "https://api.dropboxapi.com/2/users/get_current_account";

 OkHttpClient client = new OkHttpClient();

 RequestBody body = new MultipartBuilder().type(MultipartBuilder.FORM)
 .addFormDataPart("code", code)
 .addFormDataPart("grant_type", "authorization_code")
 .addFormDataPart("client_id", AuthKeyConstants.DROPBOX_APP_KEY)
 .addFormDataPart("client_secret", AuthKeyConstants.DROPBOX_APP_SECRET)
 .addFormDataPart("redirect_uri", AuthKeyConstants.DROPBOX_REDIRECT_URL)
 .build();
 Request request = new Request.Builder()
 .url(DROPBOX_TOKEN_ENDPOINT)
 .post(body)
 .build();
try {
 Response response = client.newCall(request).execute();
if (response.isSuccessful()) {
 String responseBody = response.body().string();
 JsonObject json = (JsonObject) new JsonParser().parse(responseBody);
 String accessToken = json.get("access_token").getAsString();
 String accountId = json.get("uid").getAsString();
 response.body().close();
 Request userRequest = new Request.Builder()
 .url(DROPBOX_ACCOUNT_INFO_ENDPOINT)
 .addHeader("Authorization", "Bearer " + accessToken)
 .build();
 Response accountResponse = client.newCall(userRequest).execute();
if (accountResponse.isSuccessful()) {
 responseBody = accountResponse.body().string();
 accountResponse.body().close();
 json = (JsonObject) new JsonParser().parse(responseBody);
 String userName = json.get("name").getAsJsonObject().get("display_name").getAsString();
// save new Dropbox account here
 } else {
return ERROR_RESPONSE_UNSUCCESSFUL;
 }
 } else {
return ERROR_RESPONSE_UNSUCCESSFUL;
 }
 } catch (IOException e) {
 e.printStackTrace();
return ERROR_EXCEPTION;
 }

The first call is a success, i get access_token no problem from there. I used debugging to see everything in accountResponse and this is what i got: success = false, body = null, code=400, message=Bad Request, url=https://api.dropboxapi.com/2/users/get_current_account}

Steve M.

How about this so you can see the actual response body?

} else {
    String responseBody = accountResponse.body().string();
    // log or just inspect responseBody

    accountResponse.body().close();

    return ERROR_RESPONSE_UNSUCCESSFUL;
}
