Dropbox API v2

[Terenz]

Hello,

I want to know the metadata of a file

ConsoleWrite(_Dropbox_v1("YOUR_AUTH", "/File.txt") & @CRLF)
ConsoleWrite(_Dropbox_v2("YOUR_AUTH", "/File.txt") & @CRLF)

Func _Dropbox_v1($sAccessToken, $sPath = "")
    $oHTTP = ObjCreate("WinHttp.WinHttpRequest.5.1")
    $oHTTP.Open("GET", "https://api.dropbox.com/1/metadata/auto/" & $sPath, False)
    $oHTTP.SetRequestHeader("Content-Type", "application/x-www-form-urlencoded;")
    $oHTTP.SetRequestHeader("Authorization", "Bearer " & $sAccessToken)
    $oHTTP.Send()

    $oReceived = $oHTTP.ResponseText
    $oStatusCode = $oHTTP.Status
    If ($oStatusCode <> 200) Then Return $oHTTP.ResponseText
    Return SetError(1, 0, $oHTTP.ResponseText)
EndFunc   ;==>_Dropbox_v1

Func _Dropbox_v2($sAccessToken, $sPath = "")
    $oHTTP = ObjCreate("WinHttp.WinHttpRequest.5.1")
    $oHTTP.Open("POST", "https://api.dropbox.com/2/files/get_metadata", False)
    $oHTTP.SetRequestHeader("Content-Type", "text/plain; charset=dropbox-cors-hack")
    $oHTTP.SetRequestHeader("Authorization", "Bearer " & $sAccessToken)
    $oHTTP.Send()

    $oReceived = $oHTTP.ResponseText
    $oStatusCode = $oHTTP.Status
    If ($oStatusCode <> 200) Then Return $oHTTP.ResponseText
    Return SetError(1, 0, $oHTTP.ResponseText)
EndFunc   ;==>_Dropbox_v2

The first version work fine but:

As of today, Dropbox API v1 is deprecated...we’ll be turning off API v1 a year from now, on 6/28/2017

So i need to make it work with v2. API v1 → v2 Migration guide:

https://www.dropbox.com/developers/reference/migration-guide

I'm intrestend in only:

/1/metadata --> /2/files/get_metadata

https://www.dropbox.com/developers/documentation/http/documentation#files-get_metadata

The error i have is:

Error in call to API function "files/get_metadata": request body: could not decode input as JSON

Searching around i have found this:

Quote

Finally! this worked for me:

return Parse.Cloud.httpRequest({
  method: 'POST',
  url: 'https://api.dropboxapi.com/2/users/get_current_account',
  headers: {
    'Content-Type': 'application/json; charset=utf-8',
    'Authorization': 'Bearer ' + newAccessToken
  },
  body: JSON.stringify(null)
});

I had to use JSON.stringify(null) in the body.

I don't know the alternative to "stringify" in autoit. An help? Thanks

stringify just returns the string representation of the object you out in the parameter.

Doing " JSON.stringify(null)" in the console in firefox returns "null", i would also suggest doing "{}" if it's simply an empty object you wish to parse

 

Edit:

I also noticed the $sPath is not being used by the function in v2. This is how it should work now (yes i know it would be better to verify the characters in the $spath apply to the content rules of a URL syntax)

Func _Dropbox_v2($sAccessToken, $sPath = "")
    $oHTTP = ObjCreate("WinHttp.WinHttpRequest.5.1")
    $oHTTP.Open("POST", "https://api.dropbox.com/2/files/get_metadata", False)
    $oHTTP.SetRequestHeader("Content-Type", "text/plain; charset=dropbox-cors-hack")
    $oHTTP.SetRequestHeader("Authorization", "Bearer " & $sAccessToken)
    $oHTTP.Send('{"path":"'&$sPath&'"}')

    $oReceived = $oHTTP.ResponseText
    $oStatusCode = $oHTTP.Status
    If ($oStatusCode <> 200) Then Return $oHTTP.ResponseText
    Return SetError(1, 0, $oHTTP.ResponseText)
EndFunc   ;==>_Dropbox_v2

Edit2:

Also, I'm happy you upload an example to run without extra work, however i suspect the accessTokens are private keys referring all activity to you? Maybe keep them for yourself

Don't worry about AccessTokens. Yes there are key referring to an account but i have created that account just for this thread with only 1 file, i'll delete it since i'm solve this.

Path with v1 was optional parameter, with v2 seems not...stupid mistake.

Thanks

Seems correct but not work. Thanks

There's a backslash before the ". normally the string would close, but the backslash escapes the character and boom! syntax error. Simply remove the backslash like so:

$oHTTP.Send('{"path":"'&$sPath&'","include_media_info": false}')
