MWareman Posted April 21, 2014 Share Posted April 21, 2014 ...or is it a Beta issue. Not sure yet. I have a PHP script that mainly uses REST to connect to the ISY. However, I'm also obtaining the 'Description' 'Load' and 'Location' fields of objects via SOAP (since I cannot get these via REST apparently..). This has been working fine - until sometime in the last few versions.. Now on 4.2.1 and it's definitely broken currently. I don't know if it's my code - or the ISY.. So this is what I'm doing. Using REST I'm retrieving the devices (http://$ISYuser:$ISYpassword@$ISYurl/rest/nodes). I then loop thru the nodes, one at a time, and form a SOAP request - which I post to /services, extracting and parsing the XML returned to get the data I need: $SOAPreq = ""; $SOAPreq .= $node_address; $SOAPreq .= ""; $opts = array('http' => array( 'method' => 'POST', 'header' => 'Content-type: text/xml', 'content' => $SOAPreq )); $context = stream_context_create($opts); $url = "http://$ISYuser:$ISYpassword@$ISYurl/services"; $xml = simplexml_load_string(file_get_contents("http://$ISYuser:$ISYpassword@$ISYurl/services/", false, $context)); $isLoad = $xml->isLoad; $location = $xml->location; $desc = $xml->description; $ISYurl contains the IP address of the ISY, $ISYuser and $ISYpassword the user and password of the account to manage the ISY. As mentioned - this was working not so long ago on 4.0.3. Now (4.2.1), I get: Warning: file_get_contents(http://...@x.x.x.x/services/): failed to open stream: HTTP request failed! HTTP/1.1 404 OK in /var/www/api/refresh.php on line 80 Notice: Trying to get property of non-object in /var/www/api/refresh.php on line 81 Notice: Trying to get property of non-object in /var/www/api/refresh.php on line 82 Notice: Trying to get property of non-object in /var/www/api/refresh.php on line 83 Line 80 is the simplexml_load_string - so the request to /services is being rejected by ISY with a 404.. I have pointed my regular browser at http://ISY/services and get: /services not found Am I missing something? Thanks, Michael. Link to comment
Michel Kohanim Posted April 21, 2014 Share Posted April 21, 2014 Hi Michael, http://isy/services will always fail on a browser because GET is not supported on this URL As far as getting node properties, can you please do me a favor? Can you please use the Admin Console and let me know if it returns your properties for that node? With kind regards, Michel Link to comment
MWareman Posted April 21, 2014 Author Share Posted April 21, 2014 http://isy/services will always fail on a browser because GET is not supported on this URL Well, that explains that one then... As far as getting node properties, can you please do me a favor? Can you please use the Admin Console and let me know if it returns your properties for that node? Not sure it's a worthwhile test to be honest - every node is failing when I try to get the properties with a SOAP formatted POST (my code loops thru all of them - and I get the exact same error for all nodes) - and all are working in the admin console.. Strange indeed.. Maybe I'm formatting the node incorrectly - or not escaping it properly.. The nodes I get from the REST interface appear to be a simple string in the format '11 31 DC 1'.

Michel Kohanim Posted April 21, 2014 Share Posted April 21, 2014 Hello MWareman, Is it at all possible to have the output of your SOAP request saved into a file and then pasted here? It must be something simple that my eyes didn't catch. With kind regards, Michel Link to comment
MWareman Posted April 21, 2014 Author Share Posted April 21, 2014 Is it at all possible to have the output of your SOAP request saved into a file and then pasted here? It must be something simple that my eyes didn't catch. Michel, sure 9 4A EF 1 I wasn't able to capture the header (yet). If there is nothing obvious here I'll tcpdump it and capture a full packet from the wire - rather that capturing it within the php code that's generating it. Michael. Link to comment
Michel Kohanim Posted April 22, 2014 Share Posted April 22, 2014 Hi Michael, It looks correct (compared to mine). Unless the header is posting to a different URL, I do not think it's header related. This said, I would love to see the header. Perhaps the content length is not correct? With kind regards, Michel Link to comment
MWareman Posted April 23, 2014 Author Share Posted April 23, 2014 Michel, Here is a packet dump: (I obfuscated the actual URL and the basic auth header - but kept the byte counts matched by replacing

In 22:20:05.302007, the ISY ACK's the SOAP POST to /services, then replies (22:20:05.389336) with a 404. Not sure why ISY is 404'ng this... but it seems to be an issue somewhere... This is the PHP code I used that produced this tcpdump (you should be able to put this into a .php file on a PHP enabled server and replace the variables at the top): <?php ini_set("display_errors", 1); error_reporting(E_ALL); ob_end_flush(); $ISYuser = "isy_username"; $ISYpassword = "isy_password"; $ISYurl = "isy.domain.com"; $node_address = "11 31 DC 1"; $node_name = "Master BR Light"; echo "Getting advanced node properties from ISY. \n"; echo "Getting details for: $node_address ($node_name) \n"; $SOAPreq = ""; $SOAPreq .= $node_address; $SOAPreq .= ""; $opts = array('http' => array( 'method' => 'POST', 'header' => 'Content-type: text/xml', 'content' => $SOAPreq )); $context = stream_context_create($opts); $url = "http://$ISYuser:$ISYpassword@$ISYurl/services"; echo "POST URL: $url \n"; $xml = simplexml_load_string(file_get_contents("http://$ISYuser:$ISYpassword@$ISYurl/services", false, $context)); $isLoad = $xml->isLoad; $location = $xml->location; $desc = $xml->description; echo "$SOAPreq \n"; echo "$desc \n"; echo " \n"; echo "Reached end!"; ?> As you can see - I don't calculate content length in code - the stack does this for me (and is likely to be correct I suspect..) The HTML the browser sees from this: Getting advanced node properties from ISY. Getting details for: 11 31 DC 1 (Master BR Light) POST URL: http://isy_username:isy_password@isy.domain.com/services Warning: file_get_contents(http://...@isy.domain.com/services): failed to open stream: HTTP request failed!

Michel Kohanim Posted April 23, 2014 Share Posted April 23, 2014 Hi Michael, Thanks so very much. Just went through our code: 1. If the id is null or ISY cannot find the node with that id, you would get 500 2. The only time you would get 404 is if there's really no properties file for that node So, the main question again is whether or not the Admin Console actually returns the properties for that specific node. With kind regards, Michel Link to comment
MWareman Posted April 23, 2014 Author Share Posted April 23, 2014 No problem at all with the admin console. I'm baffled - this used to work (4.0.something....) Link to comment
Michel Kohanim Posted April 24, 2014 Share Posted April 24, 2014 Hi Michael, Thank you. Can you please try the without the '.' ? i.e. 11.31.DC.1 to 11 31 DC 1 With kind regards, Michel Link to comment
MWareman Posted April 24, 2014 Author Share Posted April 24, 2014 Hi Michael, Thank you. Can you please try the without the '.' ? i.e. 11.31.DC.1 to 11 31 DC 1 With kind regards, Michel Everything is already sent without a '.'. The '.' in the tcpdump represents an 'unprintable' character - you have to look at the hex code on the left. In this case it's ACSII code 20 - a space. Do you want me to try it with a '.'? Thanks, Michael. Link to comment
Michel Kohanim Posted April 25, 2014 Share Posted April 25, 2014 Hi Michael, Got it ... you are correct. Can you do me a favor? Can you please: 1. Save your Error Log 2. Clear your Error Log 3. Go to Event Viewer, change the level to 3 4. Try your program 3 (or more) times 5. Get the Error Log, save it and send it to support@universal-devices.com With kind regards, Michel Link to comment
MWareman Posted April 25, 2014 Author Share Posted April 25, 2014 Michel, I'll get the log to you in email (it's pretty small). I wanted to post what I saw. I ran the exact program posted in this thread (the single node version) - and each time it runs I get this is the log: [FileOpen ] Open failed for [CONF/47.PRP] ® Do you know what this means? Thanks, Michael. Link to comment
MWareman Posted April 25, 2014 Author Share Posted April 25, 2014 Mystery Solved... I edited the node in question - went to 'Notes' and entered something in the 'Location' string. Now - I don't get the 404 - for that device. I realize that the properties file does not exist unless there are properties to store - but it seems really odd that ISY would return 404 to a request for properties like that. Is there any way ISY could simply 200 the request - and return XML indicating that the properties are empty? It certainly used to work that way.. Michael. Link to comment
MWareman Posted April 25, 2014 Author Share Posted April 25, 2014 Michel, The more I think about it, the more I feel 404 is the correct response. I'm asking for properties, and if none are defined they don't exist. 404 'seems' correct. I should be checking that in the code though - and its certainly a change in behavior at some point. ISY used to return XML, just with empty strings. Now it returns 404. So that I don't have to change the code again, is this current behavior the design - or a feature that will be rectified in a future version? Thanks for all your help, it helped me get to the root of what seemed to me like a very strange issue. Michael. Link to comment
Michel Kohanim Posted April 25, 2014 Share Posted April 25, 2014 Hi Michael, You are correct. There is an inconsistency here. SOAP request should not return a 404 as does a regular http response. We'll investigate to see how intrusive this could be and what else it could impact. Thanks so very much for the feedback and your patience. With kind regards, Michel Link to comment
MWareman Posted April 25, 2014 Author Share Posted April 25, 2014 Sounds perfect - thanks! For the time being, I'm going to change my code to check for 404, and just instance zero byte variables so that the rest of my code simply sees these as empty values, as it was doing before. That way it will keep functioning g for now and if you change the response in the future it will keep on working. Thank you very much for working thru this with me! Michael. Link to comment
Michel Kohanim Posted April 25, 2014 Share Posted April 25, 2014 Hi Michael, First of all, thank you for bringing this to our attention. Secondly, thank you for updating your code as this seems to be a little bit more intrusive since many SOAP calls that access the file system. Thanks again so very much, With kind regards, Michel Link to comment
