I'm working on a webservice using SoapServer in PHP. Previously, I made another webservice using exactly the same technique. My new project is on the same server, but in another subdirectory.
In the url of the service and the soapserver is a version number included.
This is the way my SoapServer is created in PHP:
$server = new SoapServer("https://".DOMAIN."/webservice/index.php?v=1.0.0&wsdl=1");
$server->setClass('SoapHandler');
$server->handle();
The whole PHP page is the same in my example Soap Service, only the url is different ofcourse.
When I do a call to the webservice with soapUI, the following error is returned:
SOAP-ERROR: Parsing WSDL: Couldn't load from 'https://myurl.com/webservice/index.php?v=1.0.0&wsdl=1' : failed to load external entity "https://myurl.com/webservice/index.php?v=1.0.0&wsdl=1"
As you can see, the ampersand is replaced with &. I tried to change the encoding to UTF-8, this doesn't work either.
Who can help me out?
You have to enable your openssl module in your php.ini file. Otherwise you can't access a domain with SSL (https).
Otherwise you should check your domain from your local server and check the return of the WSDL file with curl or lynx.
We had an .htaccess, only allowing my IP address while it should also allow the server's IP.. Deleting this solved the problem. Thanks for your help!

This issue has been plaguing me for a few hours. I can access the wsdl perfectly fine in my browser and using curl, however PHP SoapClient returns an error when using the following code:
$ps_client = new SoapClient("https://ppds.hitpromo.net/productData");
Here is the error it's returning:
Fatal error: Uncaught SoapFault exception:
[WSDL] SOAP-ERROR: Parsing WSDL: Couldn't load from 'https://ppds.hitpromo.net/productData' :
failed to load external entity "https://ppds.hitpromo.net/productData"
I tried a variety of solutions including setting various options when calling the constructor but nothing seems to be working.
This ended up not being the actual fix, it was happening because SSL was not enabled in php. I fixed it by commenting out this line in php.ini:
extension=openssl
In my case, I was able to construct the SoapClient using the http uri, however it threw an error when calling functions because SSL was not enabled.
OLD ANSWER:
Turns out this was a really simple fix. I'm not sure why, but changing it from https to http fixed everything:
$ps_client = new SoapClient("http://ppds.hitpromo.net/productData");
Really frustrating issue, because I've been playing around with this same WSDL on java and did not run into this while using ksoap. I wanted to post it because I'm sure someone might have the same problem some day.
This error occurs because your site is on a host whose firewall prevents swaps.
Contact your host company to add the IP of the swap site to the firewall whitelist.
You do not need to delete ssl or coding to ignore it.
I'm using PHP to make SOAP request. I do have information of the web service from the third party. Basically what they have give me:
The full URI request ( http://xx.xx.xx.xx:xxxxxx/some/services/BasicDo )
Username & Password
I am pretty new however I could understand a bit how PHP SOAP things work. However in the example I found the URL called is something like http://xx.xx.xx.xx/services/myservice?wsdl which is not really same with what I have with me. Additional question here is what should I ask them? Perhaps what is the name of wsdl file?
Also so far I have this code with me:
try{
$client = new SoapClient("http://xx.xx.xx.xx:xxxxx/some/services/BasicDo?wsdl", array('login'=>"myusername",'password'=> "mypwd"));
}
catch(SoapFault $fault) {
trigger_error("SOAP Fault: (faultcode: {$fault->faultcode}, faultstring: {$fault->faultstring})", E_USER_ERROR);
}
But from the console, I received status 500 Internal Server Error. I don't know how this can be, I am expecting something from the catch block. Somebody please clarify me this. Thank you in advance.
Unfortunately, it seems like no matter what you try (e.g. passing array('exceptions' => 0), SoapClient() will throw an uncatchable E_ERROR on network connection issues. This bug is still present as high up as PHP 5.5.4 (REF).
Summary:
Test script:
$client=#new SoapClient('garbage',array('exceptions'=>FALSE));
echo 'OK';
Expected result: We should see "OK",
Actual result:
If we use register_shutdown_function to display the contents of error_get_last(), we get:
Array
(
[type] => 1
[message] => SOAP-ERROR: Parsing WSDL: Couldn't load from 'garbage' : failed
to load external entity "garbage"
)
To explain why you suddenly get this error without changing anything on your system, and to explain why SoapClient works on your local machine and not on your production system, it is most likely a firewall issue.
Here is what another person reported that solved his problem:
I solved my problem. It was actually an issue with my firewall. The
firewall was dropping packets sent via PHP, but via curl or wget were
not being dropped. I added a rule for all traffic from that server and
increased the packet drop length and everything is working great now!
Advice:
My best advice at this time to write some code in the same PHP file that checks if the SOAP service url resolves and loads properly before calling the SoapClient.
Add these codes at head of the file to see where the error happen
ini_set('display_errors','1');
error_reporting(E_ALL);
I am not sure what the issue may be but I did the following to debug this issue when I encountered it
$client = new SoapClient("http://xx.xx.xx.xx:xxxxx/some/services/BasicDo?wsdl", array('login'=>"myusername",'password'=> "mypwd"));
Things you can do:
Create a PHP file. Name it anything. Write the following code there:
ini_set('display_errors','On');
$client = new SoapClient("http://xx.xx.xx.xx:xxxxx/some/services/BasicDo?wsdl", array('login'=>"myusername",'password'=> "mypwd"));
var_dump($client);
exit;
Run the file.
Chances are this will show you the required exception.
In my case, Our server used a proxy which I had not passed in the parameters due to which I was getting the issue.
Let us know how it goes.
Thanks
First you need to make sure you have access to the SOAP server.
From the machine that is running your php script try to access the wsdl file and check if it is valid.
you can for example use wget http://xx.xx.xx.xx:xxxxx/some/services/BasicDo?wsdl then open the saved file and see what you are getting. Is it a valid wsdl?
Once you have sorted out our access, then you need to read the documentation here and here. You may need to authenticate differently or pass other options.
As for why the catch block is not picking up your exception, you are only catching SoapFault. The 500 internal server error can be caused by anything.
I really appreciate all of the answers given. I am actually working with another party which I don't have any access on the remote side. My job is to make SOAP request to the server. However it turned out that there is NO web service available for me. So I ended up using cURL to send raw POST of SOAP request. :-)
I know there are countless threads on this, but nothing suggested has worked for me.
When trying to create a new SoapClient, I get the error:
Fatal error: Uncaught SoapFault exception: [WSDL] SOAP-ERROR: Parsing WSDL:
Couldn't load from 'https://m2mconnect.ee.co.uk/orange-soap/services/MessageServiceByCountry?wsdl' :
failed to load external entity "https://m2mconnect.ee.co.uk/orange-soap/services/MessageServiceByCountry?wsdl"
The WSDL file is: https://m2mconnect.ee.co.uk/orange-soap/services/MessageServiceByCountry?wsdl.
I thought it might be a https issue, but I've successfully loaded other wsdl clients. It seems to just be this EE one that won't work, and it's getting very frustrating!
I'm running my application on a vagrant instance with php5.5, on a mac os x host. I've tried running it on mac os x and I get the same problem.
I've also tried setting the 'ssl_method' option for SoapClient, but that has no effect.
I've tried to curl/wget the url and it gets an SSL error, whereas it completes the handshake with something like https://paypal.com
Does anyone have any ideas what could be causing this?
Update:
I ran this on the vagrant box: curl -v -SSLv3 https://m2mconnect.ee.co.uk/orange-soap/services/MessageServiceByCountry?wsdl and it connected successfully, however, creating a SoapClient with the option ssl_method set to SOAP_SSL_METHOD_SSLv3 doesn't work
I ended up forking BeSimpleSoapClient which wrapped SoapClient and uses Curl to get the SoapService. I modified their Curl class to allow setting of curl ssl version: https://github.com/robcaw/BeSimpleSoapClient
I was able to access the WSDL location right now with a browser.
So the only answer remaining is: IF you get SSL errors when trying to download the WSDL with curl or wget, then it is safe to assume PHP has the same error - and the solution would be to fix them - and as a first step, mentioning your findings in your question.
As it looks right now, PHP is not to blame, everything you did should work - the only thing missing is the network connection to fetch the WSDL.
I am getting an error with nusoap and/or SugarCRM. Here is the error:
XML error parsing SOAP payload on line 1: Mismatched tag
I get that in the $soapclient->error_str response. Not exactly sure what this error means or where it is located and I could use some help. So here is the background, I am working in SugarCRM with the included nusoap class and have an external site accessing the soap interface. The weird thing is that I have working copy running locally and this error only occurred when I uploaded it to my linux server.
I now I have a low reputation but if you give a working answer I will accept it. And also, I have researched the error with no luck. Any help would be much appreciated. If you need me to post any code, just let me know.
MORE INFO:
I am using SugarCRM CE 6.2.1. My soap entry point is http://server/sugar/soap.php. Here is my instation of the nusoap client.
$soapclient = new nusoap_client('http://server/sugar/soap.php');
Here is an example of a call made to the soap client
$result = $soapclient->call('update_existing_contact', array($session_id, $data));
However the error is the same for every call.
Also I get the same error when I try to use the sugar/examples/SoapTest.php so I don't think it is the client.
Like I said earlier the thing that is the most weird is that the problem only occurs on my server even when it is the same code.
I would try to use e.g. SoapUI to test the web service. If that works, you know it's most likely a problem with the client. Some other suggestions for debugging
Look in the web server log (Is the call getting through OK)
Enable the SugarCRM logging and set the level to debug
Either enable PHP error output or make PHP log errors to a log file
Use e.g. SoapUI to test SOAP call
See question 5396302 for a thorough SOAP example
Check the SugarCRM SOAP documentation
I'm trying to call a Soap Client for testing purposes from the same server that I'm running the service on. My WSDL is at: http://www.installittoday.com/api/server.php?wsdl I'm trying to load it simply with:
$client = new SoapClient('http://www.installittoday.com/api/server.php?wsdl');
but I get back the error:
Warning: SoapClient::SoapClient(http://www.installittoday.com/api/server.php?wsdl) [soapclient.soapclient]: failed to open stream: Connection timed out in /home/installi/public_html/api/client.php on line 4
Warning: SoapClient::SoapClient() [soapclient.soapclient]: I/O warning : failed to load external entity "http://www.installittoday.com/api/server.php?wsdl" in /home/installi/public_html/api/client.php on line 4
Fatal error: Uncaught SoapFault exception: [WSDL] SOAP-ERROR: Parsing WSDL: Couldn't load from 'http://www.installittoday.com/api/server.php?wsdl' : failed to load external entity "http://www.installittoday.com/api/server.php?wsdl" in /home/installi/public_html/api/client.php:4 Stack trace: #0 /home/installi/public_html/api/client.php(4): SoapClient->SoapClient('http://www.inst...') #1 {main} thrown in /home/installi/public_html/api/client.php on line 4
Yet I can set up the client just fine from another site of mine. Is this a firewall issue or what?
Make sure these extensions are enabled in your php.ini
extension=php_curl.dll
extension=php_openssl.dll
extension=php_soap.dll
Also loading from here fine.
Try connecting to it from the site you want the client on with a web browser, or if its a remote machine with no proxy set up use curl:
curl http://www.installittoday.com/api/server.php?wsdl
That will tell you if you can even get a connection to that site via the machine.
You could also try multiple connects, or increasing default_socket_timeout if your machines connection speed is limited/congested.
What ports are you trying to connect over?
For anyone coming across this error. Try disabling the WSDL cache, either from your php.ini or a parameter in your SOAP call.
The problem is, PHP by default caches the WSDL file in the temp folder. After the file is first cached, PHP keeps on using this file. It is only refreshed after 24 hours (the default ttl for the cache).
So if you change your WSDL file, PHP will pickup the old one, resulting in an error like the OP. Matt, your problem was solved by using referencing a file that is never cached.
The reason it is cached by default because your server has to request the file and then parse it, which takes a bit of fetching and processing.
You have two options, either amend the relevant variable in your php.ini or send a param along with your SOAP call.
For example:
$client = new SoapClient($webservice, array('classmap' => $soap_class_map, 'cache_wsdl' => WSDL_CACHE_NONE));
Hope this helps.
OP again here.
A little more context: I'm hosting the service (obviously) on installittoday.com. I'm also trying to run a client from the same place just for testing purposes. I can connect to the service from literally every other site I've tried perfectly fine, and I've successfully opened a few WSDLs with the Client hosted on installittoday. It seems the site can't connect to itself for some reason.
I sincerely doubt it's a congested line issue.
Now that I've gotten this far I realize this problem probably extends beyond SOAP to some kind of Apache configuration issue, unless there's a port thing that I'm missing. I haven't set up any ports differently, is there one I should make sure I have open for SOAP?
I solved this problem by saving the dynamically generated nusoap WSDL as a standalone file and all seems to be working just fine. I have no idea why this would be the case.
I'm planning to move it to PHP5 anyway, I was just using nuSoap to generate the WSDL.
