Help downloading a non-image file using the API
I am trying to use the v2 API to to get a temporary link to a file. JPG files work fine, but I have some .dcm files. These are medical image DICOM format files. I need to be able to create a tempo...

Dropbox Community ModeratorHi Bryan, to clarify, are you calling /2/files/get_temporary_link with that parameter? That shouldn't produce an error like that. Please share the full request and response (just be sure to redact the access token) so we can take a look. Thanks!
Thank you for your reply.
When I log into dropbox, this is the URL for the file preview:
https://www.dropbox.com/home/DICOM/13c76bf2914c6d87786d555f0994c531?preview=1.dcm
Here is the call I am making to the API:
URL: https://api.dropboxapi.com/2/files/get_temporary_link
Auth: Bearer TOKEN
JSON Post:
{"path":"/DICOM/13c76bf2914c6d87786d555f0994c531/1.dcm"}
Response:
Invalid URL: https://api.dropboxapi.com/2/files/get_temporary_link
I think that's it. Your help is greatly appreciated.

Thanks Bryan. That is the correct URL for this API endpoint, and that doesn't seem to be the actual API request/response though.
For example, using curl, this works for me: (just using a made up 1.dcm file in my test account)
$ curl -vX POST https://api.dropboxapi.com/2/files/get_temporary_link \ > --header "Authorization: Bearer <ACCESS_TOKEN>" \ > --header "Content-Type: application/json" \ > --data "{\"path\":\"/DICOM/13c76bf2914c6d87786d555f0994c531/1.dcm\"}" > POST /2/files/get_temporary_link HTTP/1.1 > User-Agent: curl/7.33.0 > Host: api.dropboxapi.com > Accept: */* > Authorization: Bearer <ACCESS_TOKEN> > Content-Type: application/json > Content-Length: 56 > } [data not shown] * upload completely sent off: 56 out of 56 bytes < HTTP/1.1 200 OK * Server nginx is not blacklisted < Server: nginx < Date: Thu, 27 Jul 2017 23:19:17 GMT < Content-Type: application/json < Transfer-Encoding: chunked < Connection: keep-alive < Vary: Accept-Encoding < Vary: Accept-Encoding < Cache-Control: no-cache < Pragma: no-cache < X-Content-Type-Options: nosniff < X-Dropbox-Http-Protocol: None < X-Dropbox-Request-Id: 388c65354c4b571dbcc5ce3e25d736f0 < X-Frame-Options: SAMEORIGIN < X-Server-Response-Time: 315 < { [data not shown] 100 811 0 755 100 56 835 61 --:--:-- --:--:-- --:--:-- 940 * Connection #0 to host api.dropboxapi.com left intact { "metadata": { "name": "1.dcm", "path_lower": "/dicom/13c76bf2914c6d87786d555f0994c531/1.dcm", "path_display": "/DICOM/13c76bf2914c6d87786d555f0994c531/1.dcm", "id": "id:25N5ksooX-sAAAAAAAMc8Q", "client_modified": "2017-07-27T21:46:04Z", "server_modified": "2017-07-27T21:46:05Z", "rev": "71d18021eccc7", "size": 9, "content_hash": "824979ede959fefe53082bc14502f8bf041d53997ffb65cbbe3ade5803f7fb76" }, "link": "https://dl.dropboxusercontent.com/apitl/1/AACh0gTVcnX-KmJkXbSH5qALdmLo1QoLJyQHbpVRXKVYBbn2ZFaJsIXdAXr1JM0sTg7RiQPaeymbJmyeSpkDaA505w_9tl_W6rGoXFr90T-1eMy9A3KGzfhnTORWSFbRi9JTPFJInNZepU2rZp6EzuLbjC64SXHpeVnT2F35auCpVQjDepr3hjxBudK1tF2uLmcpk5LhylRJGOpcCZrlT0hJlowU0huvfaUCqX-6ZgAiVsPDuuOVGSs-bOfNaj-LvnImgmkkG_e0fxusqFjpVu6MH0roCfouL3QQI60Izt8cFg" }What are you using to make the call? Can you share a screenshot showing it? Thanks in advance!
I used PHP and fopen. This is my function:
function do_post_request($url, $data, $optional_headers = null) { $params = array('http' => array('method' => 'POST','content' => $data)); if ($optional_headers !== null) { $params['http']['header'] = $optional_headers; } echo "<pre>";print_r($params);echo "</pre>"; $ctx = stream_context_create($params); try { $fp = @fopen($url, 'rb', false, $ctx); } catch(Exception $ex) { echo '1 Error: ' .$ex->getMessage(); } //if (!$fp) { throw new Exception("Problem with $url, $php_errormsg"); } if (!$fp) { echo "2 Error: ".$php_errormsg; } $response = @stream_get_contents($fp); echo "<pre>";print_r($response);echo "</pre>"; if ($response === false) { $response = "Invalid URL: ".$url;/*echo "Problem reading data from $url.";*/ } return $response; }

I do not know how to get any more details of why the response failed.
Any other ideas?
