I have a working call to an API using Coldfusion and cfhttp as follows:
<cfhttp url="http://api.domain.com/api/proxy.cfc" method="post" result="httpResult" charset="UTF-8">
<cfhttpparam type="url" name="method" value="apiauth"/>
<cfhttpparam type="url" name="argumentCollection" value="#jsData#"/>
</cfhttp>
The #jsData# is a json string representing an array of data.
What I'm having problems with us the
<cfhttpparam type="url" name="method" value="apiauth"/>
using cURL. If I append it to the URL as:
http://api.domain.com/api/proxy.cfc?method=apiauth
I get a response of: 302 Moved Temporarily
In PHP I've created my array as $remoteArray (and that data works fine, so the issue is not there) and I've tried this as my CURL:
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_RETURNTRANSFER => 1,
CURLOPT_URL => 'http://api.domain.com/api/proxy.cfc',
CURLOPT_POST => 1,
CURLOPT_POSTFIELDS => array(
'method' => 'apiauth',
'argumentCollection' => json_encode($remoteArray)
)
));
$resp = curl_exec($curl);
but it doesn't work (probably because method=>apiauth isn't a post field - it's a URL param - but I get a 302 if I actually put it in the URL.
SOLVED - the $remoteArray did have an error in it. Originally the $apiauthkey, $apicomponent and $apimethod were defined outside of the array. Once they were added into the array for json encoding it worked. Here's house the $remoteArray was built:
$remoteArray = array(
"apiauthkey" => "$apiauthkey",
"apicomponent" => "$apicomponent",
"apimethod" => "$apimethod",
"apiarguments" => array(
'address_1'=>"test 1",
'address_2'=>"test 2",
'city'=>"new york",
'email'=>"user#domain.com",
'first_name'=>"test fname",
'last_name'=>"test lname",
'ph_num'=>"2155551212",
'state'=>"NY",
'zip'=>"90210",
'rbpid' => $rbpid,
)
);
Once the nested array was setup properly it works fine with cURL. Thanks to those who responded!
Not an official answer just a structural example for the OP to reference because of the PHP crossing over:
fieldType can be url or formfield
method can be get or post
In the password example I already authed so I am just passing the token so i can get something.
Your argscollection is a structure...so you can loop over it.
the requestOject is a normal structure of common expected things in the cfhhtp call the name and the matching argsCollection value (and then the type of parameter)
<cfhttp url="#url#"
method="#method#"
result="response"
username="#AccountID#"
password="#AuthToken#">
<cfloop collection="#argscollection#" item="v">
<cfhttpparam name="#parameterTarget(v, requestObject)#"
value="#argscollection[v]#"
type="#fieldType#" />
</cfloop>
</cfhttp>
<cfdump var="#response#">
I'm sure this will shake a few more 'possibilities' free from your mind. Or inspire another CFHTTP expert to chime in...
Also if this is a common library you are pulling from/talking to, then consider RIAForge, CFLib or GitHub because chances are there is a Coldfusion wrapper already built and waiting for you there.
the $remoteArray did have an error in it. Originally the $apiauthkey, $apicomponent and $apimethod were defined outside of the array. Once they were added into the array for json encoding it worked.

Trying to help out someone who is trying to access and API using PHP. My code using ColdFusion works fine posting to the API, but we can't get the PHP to work. In CF the code uses urlparams to send the data:
<cfhttp url="https://example.com/_api/proxyApi.cfc" method="post" result="httpResult" charset="UTF-8">
<cfhttpparam type="url" name="method" value="apiauth"/>
<cfhttpparam type="url" name="argumentCollection" value="#jsData#"/>
</cfhttp>
A dump of the resulting call from the API shows the variables in the URL like this:
method = apiauth is the main authorization function, and then the json string in argumentCollection is passed to the correction function in the API by apiauth.
From PHP his curl is posting as form data, not URL and the API complains that the required information is missing because it's in the wrong scope. I've been trying to figure out how to make curl use URL scope instead:
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_RETURNTRANSFER => true,
CURLOPT_URL => $target_url,
CURLOPT_POST => 1,
CURLOPT_FOLLOWLOCATION => true,
CURLOPT_MAXREDIRS => 2,
CURLOPT_AUTOREFERER => true,
CURLOPT_POSTFIELDS => array(
'method' => 'apiauth',
'argumentCollection' => $json
)
));
The same dump from the API shows the same data, but in the wrong scope:
It seems like if we can get the data in the right scope we'll make progress, but my PHP knowledge is dangerously limited.
You are sending an empty POST in your CF example.
<cfhttpparam type="url" is processed as a query string parameter, as in:
https://example.com/_api/proxyApi.cfc?method=apiauth&argumentCollection=...
Thus your dump of the URL scope (the key-value-paired query string) shows the data.
To put those parameters into your POST body, you would use:
<cfhttpparam type="formfield"
And then you FORM scope would show the data.
Your PHP cURL does the latter: it adds your parameters to the POST body.
If you want the cURL to work as your example CF code, do this instead:
// add the parameters to the URL's query string
// start with & instead of ?, if the URL already contains a query string, see comment below snippet
$target_url .= '?'.'method=apiauth'.'&'.'argumentCollection='.urlencode($json);
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_RETURNTRANSFER => true,
CURLOPT_URL => $target_url,
CURLOPT_FOLLOWLOCATION => true,
CURLOPT_MAXREDIRS => 2,
CURLOPT_AUTOREFERER => true
));
no query string in $target_url:
$target_url = 'https://example.com/_api/proxyApi.cfc';
$target_url .= '?'.'method=apiauth'.'&'.'argumentCollection='.urlencode($json);
query string in $target_url:
$target_url = 'https://example.com/_api/proxyApi.cfc?p=';
$target_url .= '&'.'method=apiauth'.'&'.'argumentCollection='.urlencode($json);
On a side note: You probably don't want to send JSON via query string as the query string has a limit of about 2000 chars (depends on browser and webserver). If your JSON is complex, your query string will be truncated and mess everything up. Use the POST body for this instead.
I've got two different remote forms which I need to submit data to. The first one is an http form, and it works just fine. Submit > redirect to result page > return response as variable.
The second one lives on an https page, and it just doesn't work, no matter what I try. So here's what I'm working with:
First form's form tag
<form method="post" name="entry_form" action="a_relative_page.asp?start=1">
Second form's form tag
<form method="post" novalidate enctype="multipart/form-data" action="https://asubdomain.formstack.com/forms/index.php" class="stuff" id="stuff1234567890">
Both buttons are completely unremarkable, with no fancy javascript, and look essentially like
<input type="submit">
And here's the PHP cURL request
$post_data = http_build_query(
array(
'lots_of' => 'values_here'
)
);
$url = 'https://asubdomain.formstack.com/forms/a_page_with_form';
$ch = curl_init($url);
$opts = array(
CURLOPT_SSL_VERIFYPEER => FALSE,
CURLOPT_SSL_VERIFYHOST => FALSE,
CURLOPT_UNRESTRICTED_AUTH => TRUE,
CURLOPT_VERBOSE => TRUE,
// Above options for debugging because I'm desperate
CURLOPT_CONNECTTIMEOUT => 30,
CURLOPT_USERAGENT => 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)',
CURLOPT_RETURNTRANSFER => TRUE,
CURLOPT_FOLLOWLOCATION => TRUE,
CURLOPT_POST => TRUE,
CURLOPT_POSTFIELDS => $post_data
);
curl_setopt_array($ch, $opts);
//Capture result and close connection
$result = curl_exec($ch);
$debug = curl_getinfo($ch);
curl_close($ch);
There's nothing out of the ordinary in curl_getinfo except the expected ["ssl_verify_result"]=> int(0), which I'm ignoring for debugging.
HTTP code is 200. If I echo $result, I can see that all form values are filled out, but the form never submitted and thus never redirected. If I then CLICK on submit, the form submits without issue and redirects as expected.
Again, this is not a problem with the first form, only the second. I'm guessing there's something about the underlying code on formstack that prevents cURL POST from submitting the form, but I can't seem to find it.
EDIT: I found the problem. There are two invisible elements on formstack forms. One of them is an input field called _submit which must be set to 1. The other is the form identifier, which is an integer.
I wrote very simple code to retrieve soap data:
$wsdl = 'https://...';
$client = new SoapClient($wsdl, ['trace' => true]);
$soap_parameters = [
'leveranciernaam' => 'xxx',
'leveranciersleutel' => 'yyy',
'brinnummer' => 'zzzz',
'schooljaar' => 2012
];
$response = $client->getLeerlingen($soap_parameters);
To my huge surprise, the return was different from the return i received while using a Java based GUI application.
Some fields in PHP SoapClient's response were consistently missing.
Just to make sure that things were not lost in translation to stdObjects, I used trace option to and extracted actual XMl from $client->__getLastResponse();
Still those fields were not there - very consistently over hundreds of records.
Windows Java based client's response:

PHP client does not get (or does not properly parse) any elements schoolVanHerkomst, vervolgSchool and onderwijsSoortBestemming in element inschrijving and it misses brins completely.
For brevity, I omitted other deeply nested elements that work just fine
Because expected results are dynamic, WDSL ( https://acceptatie.parnassys.net/bao/services/cxf/v1/generic?wsdl ) does not define ouput.
What is going on? It seems that PHP Soap client is less reliable than Java Soap clients
I have a project where I need to do the following: retrieve some data from a form, fill the database, create a response for the user and post the data to a third party. To give an example, it's like booking a ticket to a concert.The ajax call: You buy the ticket, you receive a response (whether the purchase was successful), a php script sends data to the database, and someone may be announced that a new ticket was bought. Now, I need to pass data to that "someone". Which is what I don't know how to do.
Or, like when someone posts a comment to my question on stackoverflow, I get a notification.
In my particular case, the user creates an event, receives a response and I will need to have certain parameters posted by the user on a calendar. It is important that I could hardly integrate the calendar with the script retrieving the data. I would rather need to "forward" the data to the calendar- quite like pushing notifications.
Can anyone please give me a clue what should I use, or what should I need in order to do the above?
The process will go like this:
AJAX
user----> php script->database
|_ calendar
So if i get you right, you could post your data to the calendar via curl:
$url = "http://www.your-url-to-the-calendar.com";
$postData = array(
"prop1" => "value1",
"prop2" => "value2",
"prop3" => "value3"
);
//urlify the data for the post
$data_string = "";
foreach ($postData as $key => $value)
$data_string .= urlencode($key) . '=' . urlencode($value) . '&';
$data_string = rtrim($data_string, '&');
//will output --> prop1=value1&prop2=value2=prop3=value3
$ch = curl_init();
curl_setopt_array($ch, array(
CURLOPT_URL => $url,
CURLOPT_HEADER => false,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_FOLLOWLOCATION => false,
CURLOPT_POST => count($postData),
CURLOPT_POSTFIELDS => $data_string
));
$result = curl_exec($ch);
If your third party calendar does not require authentication than this would be the best way to post it, if you can not write to the database yourself.
When it requires authentication you would have to first login via curl (send credentials via curl-post, receive cookies, send cookies with your data)
Hope this helps.
I have the Simple HTML DOM Parser for PHP, and I am using the following markup:
$html = file_get_html('http://www.google.com');
However how do I send post variables (like a cURL) to that page and get the response? For example
$html = file_get_html('http://www.google.com', array("Item"=>"Value", "Item2"=>"Value2"));
The documentation doesn't mention it as far as I can see, but after taking a look in the source code I noticed the function you're using accepts a stream context as its third argument. You can create a post request with this PHP feature like this:
$request = array(
'http' => array(
'method' => 'POST',
'content' => http_build_query(array(
'Item' => 'Value',
'Item2' => 'Value2'
)),
)
);
$context = stream_context_create($request);
$html = file_get_html('http://www.google.com', false, $context);
If you don't like contexts or would prefer a different method (like the cURL extension) you could also just fetch the page content using that, then feed it to the parser with str_get_html() or $parser->load(); the class itself does pretty much the same internally with the method you're using right now.
