[Uus Khusni]

Hallo

I am from Indonesia, and newbie in dataverse. I try to call API dataverse from PHP to import dataset JSON into dataverse but i got messege

{"status":"ERROR","code":404,"message":"'/api/v1/dataverses/puslitekonomi-lipi/:import' endpoint does not exist on this server. Please check your code for typos, or consult our API guide at http://guides.dataverse.org."}

Please help us, below is my code write on PHP

$url = 'https://xxx/api/dataverses/xxx/:import?pid=xxx&release=no&key=xxx';

//create a new cURL resource
    $ch = curl_init($url);
    //echo $url;
    //HTTP username.
    $username = 'xxx';
//HTTP password.
    $password = 'xxx';
//setup request to send json via POST
    $payload = json_encode($array_dataset);
//attach encoded JSON string to the POST fields

    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $payload);

//set the content type to application/json
    curl_setopt($ch, CURLOPT_HTTPHEADER, array(
        'Content-Type:application/json',
        'Authorization: Basic '. base64_encode("$username:$password")));

//return response instead of outputting
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

//execute the POST request
    $result = curl_exec($ch);

    echo $result;
    //echo 'Request Error:' . curl_error($ch);
//close cURL resource
    curl_close($ch);

Hi Uus,

It's been a while since I've done any PHP but I just asked at I asked at http://irclog.iq.harvard.edu/dataverse/2019-06-11#i_97075 and Jeremy Richard figured out what the problem is, I think.

(You are welcome to join us at http://chat.dataverse.org of course!)

That "endpoint does not exist on this server" error is easy to trigger. If you go to https://demo.dataverse.org/api/doesNotExist for example, you will see that error.

The problem seems to be that the "path" in your $url is missing the word "datasets". Instead of...

$url = 'https://xxx/api/dataverses/xxx/:import?pid=xxx&release=no&key=xxx';

... you should try something like...

$url = 'https://xxx/api/dataverses/xxx/datasets/:import?pid=xxx&release=no&key=xxx';

For comparison, here's the curl example from http://guides.dataverse.org/en/latest/api/native-api.html#import-a-dataset-into-a-dataverse

curl -H "X-Dataverse-key: $API_TOKEN" -X POST $SERVER_URL/api/dataverses/$DV_ALIAS/datasets/:import?pid=$PERSISTENT_IDENTIFIER&release=yes --upload-file dataset.json

Finally, have you considered contributing a PHP client library for Dataverse? I would be happy to create a repo at https://github.com/IQSS/dataverse-client-php and give you "push" access to it! All of the client libraries listed at http://guides.dataverse.org/en/4.14/api/client-libraries.html have been contributed by the community.

Thanks,

Phil
