Hi!

To download a file from Dropbox is easy:

ZnClient new https; host: 'content.dropboxapi.com'; addPath: '2'; addPath: 'files'; addPath: 'download'; headerAt: 'Authorization' put: 'Bearer

<my generated access token> ';

...

headerAt: 'Dropbox-API-Arg' put: '{"path": "/demo.txt"}' ;get.

But I cannot figure out how to get file metadata (https://www.dropbox.com/developers/documentation/http/documentation#files-ge...).

If I try the following

(ZnClient new https; host: 'api.dropboxapi.com'; addPath: '2'; addPath: 'files'; addPath: 'get_metadata'; headerAt: 'Authorization' put: 'Bearer QfCCKhxI-HwAAAAAAAAGdeT916yqY4tkX3EN6EW2S3EMxYyv5Xky9LeCxuGi8_o7'; headerAt: 'Content-Type' put: 'application/json'; formAt: 'path' put: 'demo.txt'; post).

I get the error message from Dropbox:

Error in call to API function "files/get_metadata": Bad HTTP "Content-Type" header: "application/x-www-form-urlencoded". Expecting one of "application/json", "application/json; charset=utf-8", "text/plain; charset=dropbox-cors-hack".

By using #formAt:put: you implicitly create a ZnApplicationFormUrlEncodedEntity instance, this is not what you want/need. This would POST proper JSON:

ZnClient new https; host: 'api.dropboxapi.com'; addPath: '2'; addPath: 'files'; addPath: 'get_metadata'; headerAt: 'Authorization' put: 'Bearer QfCCKhxI-HwAAAAAAAAGdeT916yqY4tkX3EN6EW2S3EMxYyv5Xky9LeCxuGi8_o7'; entity: (ZnEntity with: (STONJSON toString: { #path->'demo.txt' } asDictionary) type: ZnMimeType applicationJson); post.

Does that work ?

yes, it does thanks a lot -- View this message in context: http://forum.world.st/Zinc-newbie-question-How-to-get-file-metadata-from-Dro... Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
