Issues with the DOI-CrossRef automatic registration

vmarinj · October 18, 2016, 9:54am

Hi there,
I have been trying to register all the articles of a journal in OJS 2.4.8.0 through the Exportation plugin of CrossRef XML.
First I had an error related to the publication date of the issues and we solved it and now another error is showing up and I do not know exactly where it could be.
We have checked the username and password for CrossRef and it seems that everything is ok…

I have also checked some topics on this forum, but the error seems to be different that ours.

It says the following:
No se pudo realizar el registro. El servidor de registro DOI ha devuelto un error: ‘No response from server.’. (The register could not be done. The server of the DOI register has given an error: No response from server).

I have also tried to export the XML for all the articles with the plugin but it shows a white screen. It seems that it has nothing to do with the amount of articles, because I have also tried only checking one or few articles each time.

Someone has some solution for this?

Thank you very much.

The message of “No response from server” indicates that your server is having trouble connecting to the CrossRef server at https://api.crossref.org/deposits .

Some possible considerations:

Is this server behind a proxy? Do you have a proxy configured in config.inc.php?
Does your PHP have cURL support enabled?
Does cURL support HTTPS?

You can get details on the white screen at export by looking at your web server’s error log:

@ctgraham

I am having a similiar issue with exporting DOI. I am using the current version of OJS. Can you help me with this

ctgraham · April 1, 2021, 2:39pm

@a2usmani , please share your specific steps to reproduce the problem, and the error messages you see, both those messages on the screen and any messages from your webserver’s error log.

a2usmani · April 2, 2021, 9:12am

@ctgraham Thanks for your reply.

I use the default plugin for Depositing DOI. I have entered the required username and password for Crossref in the plugin.

In the plugin I goto articles and check one article and click deposit button at the end of the page.
The error I get is

Registration was not successful! The DOI registration server returned an error: 'No response from server.'.

Then I goto Cpanel > File Manager>public_html and check error log. The log is showing the following message and there is nothing else in the log

[02-Apr-2021 08:55:12 UTC] ojs2: 404 Not Found
[02-Apr-2021 08:56:37 UTC] ojs2: 404 Not Found

Now I don’t know what is the issue. I tried to google it but couldn’t get to the solution. Please help. Thankyou.

Regards

Are you comfortable modifying the code to get some additional information on why this is failing? In 3.2 and earlier, there are two places where this message appears in the CrossRef plugin:

github.com

pkp/ojs/blob/cf6013aaf94079bd14d25b284504e45b1da57dd2/plugins/importexport/crossref/CrossRefExportPlugin.inc.php#L138


		// Set the form post fields
		$username = $this->getSetting($context->getId(), 'username');
		$password = $this->getSetting($context->getId(), 'password');
		$batchId = $request->getUserVar('batchId');
		$data = array('doi_batch_id' => $batchId, 'type' => 'result', 'usr' => $username, 'pwd' => $password);
		curl_setopt($curlCh, CURLOPT_POSTFIELDS, $data);

		$response = curl_exec($curlCh);

		if ($response === false) {
			$result = __('plugins.importexport.common.register.error.mdsError', array('param' => 'No response from server.'));
		} else {
			$result = $response;
		}
		return $result;
	}


	/**
	 * @copydoc PubObjectsExportPlugin::getExportActionNames()
	 */

and

github.com

						],
						[
							'name'     => 'mdFile',
							'contents' => fopen($filename, 'r'),
						],
					]
				]
			);
		} catch (GuzzleHttp\Exception\RequestException $e) {
			if ($e->getResponse()->getStatusCode() != CROSSREF_API_DEPOSIT_ERROR_FROM_CROSSREF) {
				return [['plugins.importexport.common.register.error.mdsError', 'No response from server.']];
			}

			$response = $e->getResponse();
		}

		// Get DOMDocument from the response XML string
		$xmlDoc = new DOMDocument();
		$xmlDoc->loadXML($response->getBody());
		$batchIdNode = $xmlDoc->getElementsByTagName('batch_id')->item(0);

The exact formulation of how to log the additional error information will depend on your specific version of OJS. If you are comfortable adding some debugging code, what version are you using?

@ctgraham

Yes I am comfortable and able to add the code. Will it work.

I have three OJS installations on different servers

3.3.0.4

3.1.2.4

3.3.0.4

I having the same error on all installations. Also I received information from another friend with the same error and they asked for my help.

Please guide.

thanks

Regards

ctgraham · April 8, 2021, 12:34pm

I’m not seeing the message “No response from server” in the code for 3.3.0.4, so let’s look at the 3.1.2.4 install to try to debug. Hopefully this will give us some clues about 3.3.0.4 as well.

In /plugins/importexport/crossref/CrossRefExportPlugin.inc.php at line 142:

		}
		return $result;
	}

		} else {
			$cfile = "@$filename";
		}
		$data = array('operation' => 'doMDUpload', 'usr' => $username, 'pwd' => $password, 'mdFile' => $cfile);
		curl_setopt($curlCh, CURLOPT_POSTFIELDS, $data);
		curl_setopt($curlCh, CURLOPT_SSL_VERIFYPEER, false);
		$response = curl_exec($curlCh);

		$msg = null;
		if ($response === false) {
			$result = array(array('plugins.importexport.common.register.error.mdsError', 'No response from server.'));
		} elseif (curl_getinfo($curlCh, CURLINFO_HTTP_CODE) != CROSSREF_API_DEPOSIT_OK) {
			// These are the failures that occur immediatelly on request
			// and can not be accessed later, so we save the falure message in the DB
			$xmlDoc = new DOMDocument();
			$xmlDoc->loadXML($response);
			// Get batch ID
			$batchIdNode = $xmlDoc->getElementsByTagName('batch_id')->item(0);
			// Get re message
			$msg = $response;
			$status = CROSSREF_STATUS_FAILED;

If you change the parameter:
'No response from server.'
to
'No response from server.'.curl_error($curlCh)
then the message which appears on screen will contain additional details about why the connection is failing.

For example, after the change, the first line would look like:

			$result = __('plugins.importexport.common.register.error.mdsError', array('param' => 'No response from server.'.curl_error($curlCh)));

I changed both the lines in the filer and then tried to deposit one article. It failed and when I clicked failed link. It gave me this message. It says incorrect username and password. But I am using correct credentials which CrossRef gave me and I use it for logging in their portal and meta data manager.

Do your username or password have any special characters which might be misinterpreted? For example a quote which might have be converted to a “smart quote” in a copy and paste?

If you are able to access the database directly, does the username and password look correct there?

select setting_name, setting_value from plugin_settings where plugin_name = 'crossrefexportplugin' and setting_name in ('username', 'password');
