请求/共享返回401未经授权

Question

My request to the shared file looks like this:

request = (HttpWebRequest)WebRequest.Create(requestUri);
request.Method = WebRequestMethods.Http.Post;
response = request.GetResponse();

where the requestUri looks something like this:

https://api.dropbox.com/1/shares/auto/New%20Text%20Document.txt?
oauth_consumer_key=MY_KEY&oauth_nonce=913151&oauth_signature_method=HMAC-
SHA1&oauth_timestamp=1428055275&oauth_token=TOKEN&oauth_version=1.0&oauth_signatur
e=BLABLABLA

request.GetResponse() throws a WebException, which says:

The remote server returned an error: (401) Unauthorized . And for the detailed information I receive this: Additional information: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.

The flow is like this: I upload the file with the same authorization parameters successfully and then I try to retrieve the newly uploaded file's shortened URL using the call shown above but receive the exception.

Please note that this worked some time ago. Probably they've changed something in the API, but I cannot find how to do it correctly. So, what am I doing wrong here?

Answer 1

When I put the address into my URL it states:

{"error": "Invalid app key (consumer key). Check your app's configuration to make sure everything is correct."}

Get a new app key and see if it then works.

Answer 2

In your URL it shows oauth_consumer_key=MY_KEY I don't think so oauth_consumer_Key will generate key in that way it is just for an example.

You have to login and need to follow proper steps as below to get your App key Below URL provide you all steps.

Steps:

• Login to Dropbox
• Click on the link “Developers” which is displayed on the bottom (center) of the page
• Click on the link “My Apps” displayed in the
• menu on the left side Now click on the button “Create an App”

Answer 3

I believe we solved this via a Dropbox support ticket. As far as I can tell, the issue was that a nonce was being reused.
