API v2 with PHP

Hello

I'am trying to do a very simple thing with no result. I just try to use the V2 API with PHP cURL. Nb I a m very new on the subject...

According to the documentation I expect to receive the list of the file from my dropbox. But I do not receive anything the var_dump result is false.

Does anayone as an Idea? (I hide the $token value)

$ch = curl_init();

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");

curl_setopt($ch, CURLOPT_HTTPHEADER, array('Authorization: Bearer ' . $auth_token, 'Content-Type: application/json'));

curl_setopt($call, CURLOPT_URL, 'https://api.dropboxapi.com/2/file_requests/list');

try{

$result = curl_exec($ch);

} catch (Exception $e) {

echo 'Exception reçue : ', $e->getMessage(), "\n";

}

var_dump($result);

print_r($result);

$array = json_decode(trim($result), TRUE);

print_r($array);

curl_close($ch);

1) It looks like there are two issues with this one:

a) You should be supplying the API call parameters as JSON in the body. So, instead of:

$curl_fields = http_build_query($fields);
curl_setopt($ch, CURLOPT_POSTFIELDS,$curl_fields);

You would do something like:

curl_setopt($ch, CURLOPT_POSTFIELDS,json_encode($fields));

b) When identifying just the root folder, you need to just use the empty string "", so instead of:

"path"=> "/",

Do:

"path"=> "",

2) I'm just running this code in my terminal. I can't offer help on your development environment itself, so you'll need to investigate how to properly get the error output in your environment. For reference, the Dropbox API returns error information in the response body, which both the `var_dump($result);` and `print_r($result);` in your code are showing me.

It looks like there are some issues that would prevent this code from running properly. You should be getting some error output. When I run this, setting my own $auth_token, I get:

Warning: curl_setopt() expects parameter 1 to be resource, null given in ...test_266674.php on line 9

That's because you're using an undefined $call instead of $ch here:

curl_setopt($call, CURLOPT_URL, 'https://api.dropboxapi.com/2/file_requests/list');

That should be:

curl_setopt($ch, CURLOPT_URL, 'https://api.dropboxapi.com/2/file_requests/list');

After that, I get:

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

You should set the body to fix that:

curl_setopt($ch, CURLOPT_POSTFIELDS, "null");

Moreover, note that the API endpoint /2/file_requests/list you're using "Returns a list of file requests". That refers to the file requests feature. If you want to list the files in the connected account, you should use /2/files/list_folder[/continue] instead.

Hello

First thing, thanks a lot for your answer.

I've tried with 2/files/listfolder but unfortunately I got the same result (var_dump = false)

$ch = curl_init();

$fields =array(

"path"=> "/",

"recursive"=> false,

"include_media_info"=> false,

"include_deleted"=> false,

"include_has_explicit_shared_members"=> false,

"include_mounted_folders"=> true) ;

$curl_fields = http_build_query($fields);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");

curl_setopt($ch, CURLOPT_HTTPHEADER, array('Authorization: Bearer ' . $auth_token, 'Content-Type: application/json'));

curl_setopt($ch, CURLOPT_URL, 'https://api.dropboxapi.com/2/files/list_folder');

curl_setopt($ch, CURLOPT_POSTFIELDS,$curl_fields);

try{

$result = curl_exec($ch);

} catch (Exception $e) {

echo 'Exception : ', $e->getMessage(), "\n";

}

var_dump($result);

print_r($result);

$array = json_decode(trim($result), TRUE);

print_r($array);

curl_close($ch);

1) Do you have a idea on what's wrong with my code?

2) How do you get the error message request "body: could not decode input as JSON" ? I do not receive any message unless I test in https://resttesttest.com/ (which doesn t work neither..)

I have a problem with create folder, I get empty response from

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, "https://api.dropboxapi.com/2/files/create_folder_v2");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);

$arr = array("path"=>$from, "autorename"=>"false");
$jArr = json_encode($arr);

$arrNull = array("body"=>"");
$jNull = json_encode($arrNull);

curl_setopt($ch, CURLOPT_POSTFIELDS, $jArr);

curl_setopt($ch, CURLOPT_HTTPHEADER, [
"Authorization: Bearer Thetoken",
"Content-Type: application/json"
]);

$result = curl_exec($ch);
echo("res:" .$result);
curl_close ($ch);

Hi @tridejur,

It looks like your having a different issue than was originally reported in this thread. Can you please start a new thread with your code sample. It will also help us troubleshoot if you include the response you get back from the server.

tridejur

Hi sample is on

http://tridejur.uy/t123.php?id=18711573&alta=2018-12-22blank13:15:12%27

Code is ofuscated, but no problem in sharing since i am only using curl calls to your API as per stated on your http API samples.

I need someone to test if the problem is on your side of communication, I do use create folder and upload through your recommendations.

1) Press, createacc.bat(Enter your account)

2) place some files on outputbox

3) press send.bat

Send me a message to 26045165.
