I have installed a clean Joomla version and clean Hikashop version on my local server where I can guaranteed there is no problem with connecting to the USPS API website. Errors persist.

Apparently USPS had done something to their API which Hikashop will have to change in the plugin.

In the meantime, I have reverted to a more complicated manual shipping setup I used before enabling the USPS plugin.

Hopefully this can be resolved soon.

Hi,

By giving us useful information for debugging.
Like explain in the post 131863 : www.hikashop.com/forum/shipping-methods/...00-error.html#131863
We do not have USPS account so we can't test. So we are like blind people.

You can also follow the instruction that Nicolas gave you by mails.
And you know, we are also closed today

Hi timerlinetom

I cannot contact usps today, so can you tell me how you managed that:
"In the meantime, I have reverted to a more complicated manual shipping setup I used before enabling the USPS plugin."

Thank you

I had setup several manual shipping options increasing in price with increases in weight. This was pure guess and not very accurate. You really need to do your own calculations - mine are not correct. But at least I get something for shipping while the plugin in not working. I attached a screenshot, only good for example, you must do your own calculations.

Sorry, inserting the above code is not giving me any more information. Only 4 lines of errors I've already noted.

Edit:::
Sorry, I should have clarified. I was using the code requested in posting:
www.hikashop.com/forum/shipping-methods/...rt=0&start=20#131863

I just get a blank screen, no additional information in server logs, php error logs or displayed on the screen.

Hi,

Thanks for the information.
Can you just try to use the "view page source code" because it is possible that USPS return some XML which is not understandable for the browser so it does not display it. I should have use the "htmlentities" function in order to transform all the content into a readable HTML text..

Hi,

Interesting !
Can you modify the plugin and change the $req value by:

			$req = "GET /ShippingAPI.dll?API=" . $apiName . "&XML=" . urlencode($XMLRequest) . " HTTP/1.1\r\n".
				'Server: '.$_SERVER['SERVER_SOFTWARE']."\r\n".
				'Host: production.shippingapis.com'."\r\n".
				'Content-Type: text/xml'."\r\n".
				'Accept: */'.'*'."\r\n".
				'Connection: close'."\r\n\r\n";

Maybe sending more data for the HTTP headers will fix it.
Just an idea like that

Hi,

So I think that if you remove the "die", it should work now.. Right ?

You would think. But I still get an absolutely blank page. Using Chrome, if inspect elements, all I see is an empty table. I attached a screenshot.

Hi timberlinetom,

Mhmm, I guess that the truncated return is not read correctly by the plugin.
I think that USPS changed their servers which now only manage HTTP/1.1
The plugin developed by an external developer/company (who gave us the plugin for free) does not handle the connection like we did generally.
Well, I rewrite the function "doUPS" in order to use cURL and not a raw socket. It is quite better to respect standards and have a right processed result.

Please test this new function, I hope that it will return a better result.

	function doUSPS($XMLRequest, $domesticShipment) {
		$apiName = 'RateV4';

		// Change API name if this is an International shipment.
		// Determined by $domesticShipping boolean value.
		//
		if($domesticShipment == false)
			$apiName = 'IntlRateV2';

		$url = 'http://production.shippingapis.com/ShippingAPI.dll?API=' . $apiName . '&XML=' . urlencode($XMLRequest);

		$session = curl_init();
		curl_setopt($session, CURLOPT_FRESH_CONNECT,  true);
		curl_setopt($session, CURLOPT_POST,           false);
		curl_setopt($session, CURLOPT_FOLLOWLOCATION, false);
		curl_setopt($session, CURLOPT_FAILONERROR,    true);
		curl_setopt($session, CURLOPT_RETURNTRANSFER, true);
		curl_setopt($session, CURLOPT_COOKIEFILE,     '');
		curl_setopt($session, CURLOPT_SSL_VERIFYPEER, false);
		curl_setopt($session, CURLOPT_SSL_VERIFYHOST, false);
		curl_setopt($session, CURLOPT_ENCODING,       'UTF-8');
		curl_setopt($session, CURLOPT_URL,            $url);
		$result = curl_exec($session);
		$error = curl_error($session);

		if(empty($result)) {
			$app = JFactory::getApplication();
			$app->enqueueMessage( 'Cannot connect to USPS web service. You hosting company might be blocking outbound connections.<br/>'.$error);
			return false;
		}

		$responseDoc = simplexml_load_string($result);
		if($responseDoc === false) {
			$app = JFactory::getApplication();
			$app->enqueueMessage('Cannot dialog with USPS web service.<br/>'.$result);
			return false;
		}
		return $responseDoc;
	}

@Julian56 : I said you a high number of time that if you want to help you can make some tests, follow this thread and like the other people, try some things to solve the problem. But asking like you did, will not help anything.
We know that it is a big problem but.. sending us a lot of messages without any useful information does not help.
I prefer to be direct and honest. I hope that I am clear enough and that you understand that we also want to solve this problem as fast as possible.
At the moment that we will have a news, you will know because we concentrated the USPS problem on this single thread.

I spoke with USPS -- they are aware of the problem. It was an upgrade that went out Saturday morning and was only supposed to affect the USPS internal server but ended up affecting the production servers too.

They are working hard to come up with the coding to give us to fix out plugins but can't give me a timeframe on that. A release note will be available on the USPS.com web tools page once they have the code for us.

Jerome, that did the trick. I've shown results attached. I see "Media Mail" now as an option which did not exist before so I think you are getting better results from the API call.

Might I suggest that until you can make a new release, you upload a revised 'usps.php' file. That will spare uses the concern of which chunk of code to replace.

I'm glad to see Hikashop include the plugin for USPS shipping with the core program now. I did not realize you had no access to developer resources. Since USPS is a significant and critical shipping option for United States customers like myself ( and Julian56 ), you should check out the resources available at www.usps.com/business/web-tools-apis/ . I see that the USPS had a release of their API last July and I'm guessing they left legacy code for transition purposes which was removed last weekend. Perhaps if you get signed up on their website as a developer you can proactively update and support this important plugin. I'm afraid that while I claim a relatively high level of competence, I'm not good enough to be a programmer.

Thanks for your assistance with this.
