I've been stuck with a HTTP 400 "Bad Request" issue when trying to connect to an API for some time now.
I have a feeling it's to do with the headers, but I'm not too sure.
My query is regarding the output of the SOAP Request and whether I'm correctly setting the headers.
So the code I have to set the header is
$proxy->setHeaders('<soap:Header><AuthenticationSoapHeader xmlns="https://www.xxxxx.com/ASPAPI"><Token>xxxxx-xxxxx-xxxx</Token></AuthenticationSoapHeader></soap:Header>');
I then make a call to an API function and pass over the XML string directly after setting the headers, like so:
$result = $proxy->call('ValidateService', array('serviceXML' => $xml));
However, the output when printing $proxy->request is like so:
[TOKEN VALUE FROM HEADER HERE][CONTENTS OF XML STRING HERE]
So the request string basically prints out the contents of inside the <token> tag in the header, directly followed by the XML string.
Is it right that the <token> value is printed out in the request alongside the XML string? I have a feeling I may be incorrectly setting the headers.
The problem lies in the headers.
The <soap:Header> opening & closing tags were causing the HTTP Error 400 "Bad Request"
$proxy->setHeaders('<soap:Header><AuthenticationSoapHeader xmlns="https://www.xxxxx.com/aspapi"><Token>xxxxx</Token></AuthenticationSoapHeader></soap:Header>');
Should be
$proxy->setHeaders('<AuthenticationSoapHeader xmlns="https://www.xxxxx.com/aspapi"><Token>xxxxx</Token></AuthenticationSoapHeader>');

I am trying to fetch an external JSON response with my PHP back-end
But my problem is that the external endpoint is returned as the Content-Type: text/plain;charset=utf-8, and that only gives me gibberish when I read it.
string '����������ݒ�J�� ... etc...
Is there a way to encode that response?
This is what I have done:
$response = file_get_contents('external_url');
I have also tried this:
$json = json_decode(file_get_contents('external_url'), true);
It doesn't really matter to PHP what Content-Type the response declares, it doesn't do anything with that information. You're getting exactly the same response body whether the header says text/plain or JSON.
More likely the response is compressed and you need to uncompress it with gzinflate or such.
I am working on proxy with PHP. In my php code I am sending proper required headers and expected to get response body and headers. However I am getting response body correctly as I want but not getting headers properly (supposed to get Status 200 but getting 401). When i traced with firefox I found that SAP URL itsself making 2 request internally by using data which I send. so with my first request it is not authenticated so SAP url itslef managining to send same request again and 2nd time it gives both proper response body with headers. Howevber I php code when I get it i get response body from 2nd response and headers from 1st response.
here is code.
$opts = array(
'http'=>array(
'method'=>"POST",
'content' => $xml_request,
'header'=>array("Host:" . $sap_url,
"Content-Type: text/xml; charset=UTF-8",
$authstring,$xml_request)
)
);
$context = stream_context_create($opts);
$result = file_get_contents($sap_url, false, $context);
$http_res_array = get_headers($sap_url);
You should probably use curl functions instead and do BOTH requests yourself. file_get_contents, does the second request for you, but takes away the possibility to fetch the second headers.
Maybe a little old but anyways:
You're using the get_headers()-function to get the headers. It's documentation states that:
Fetches all the headers sent by the server in response to a [new] HTTP request
It doesn't empathize that this function will actually send a new request to the server and return the response-header for that request. Therefor, the headers can be slightly different.
Since you're using file_get_contents() to load the content, you can use the global $http_response_header-variable right after your request, which will contain the response-header from the last executed request.
My server outputs this JSON when I put the URI in web browser. My client app will get this JSON using JSONP because it accesses the foreign domain.
{
"is_execution_successful":true,
"data": "something"
}
Is there a way to do a JSONP without wrapping the response like this:
echo $_GET['json_callback']. '('. json_encode($rtnjsonobj) . ')';
I don't have permission to edit the server output. How to get the JSON using AJAX/JQuery?
Reference I read: http://remysharp.com/2007/10/08/what-is-jsonp/
JSONP has technically nothing to do with JSON. It's simply javascript code.
So if the response is valid JSON, it will not do anything useful when you run it as javascript (JSONP). Especially in this case, the JSON causes a syntax error when executed as javascript.
You can make cross-origin ajax request to the resource, but this is only possible if the server sends this header:
Access-Control-Allow-Origin: *
The star can be replaced with your specific origin of course, it doesn't have to be a wildcard
I'm implementing a PHP script which receives an HTTP POST message with in the body a json string, tied to a 'report' parameter. So HTTP POST report=.
I'm testing this out with SimpleTest (PHP Unit Testing).
I build the json:
$array = array("type" => "start"); // DEBUG
$report = json_encode($array);
I send the POST:
$this->post(LOCAL_URL, array("report"=>$json));
(calls a method in the WebTestCase class from SimpleTest).
SimpleTest says it sends this:
POST /Receiver/web/report.php HTTP/1.0
Host: localhost:8888
Connection: close
Content-Length: 37
Content-Type: application/x-www-form-urlencoded
report=%7B%22type%22%3A%22start%22%7D
I receive as such:
$report = $_POST['report'];
$logger->debug("Content of the report parameter: $report");
$json = json_decode($report);
The debug statement above gives me:
Content of the report parameter: {\"type\":\"start\"}
And when I decode, it gives the error
Syntax error, malformed JSON
The 'application/x-www-form-urlencoded' content-type is automatically selected by SimpleTest. When I set it to 'application/json', my PHP script doesn't see any parameters and as such, can't find the 'report' variable.
I suppose something is going wrong with the url encoding, but I'm lost here as to how I should get the json accross.
Also, what is the usual practice here? Does one use the key/value approach even if you just send an entire json body? Or can I just dump the json string in the body of the HTTP POST and read it out somehow? (I had no success in actually reading it out without a variable to point to).
Anyway, I hope the problem is somewhat clearly stated.
Thanks a bunch in advance.

It sounds like you have magic quotes enabled (which is a big no-no). I would suggest you disable this, otherwise, run all your input through stripslashes().
However, it is better practice to reference the POST data as a key/value pair, otherwise you will have to read the php://input stream.
For the quick fix, try:
$report = stripslashes($_POST['report']);
Better, disable magic quotes GPC. G=Get, P=Post, C=Cookie.
In your case Post. Post values get automatically ("magic") quoted with a single slash.
Read here how to disable magic quotes.
A non-hypothetical but abstracted situation:
I have a domain www.foo.com, from which I'm making an AJAX POST to beta.foo.com. Examining the XHR object, I see a response header of 200 OK, but no response text - I even get a response 12B long, which is the exact response (a 12-character string) that I'm expecting - but the response text is blank.
If this is a cross-domain issue, why am I getting 200 OK, and better yet - why am I seeing the PHP functions fire on the beta.foo.com side - yet getting no response?
You can't do cross subdomains ajax calls that easy. There is something called Same origin policy that prevents you from doing that. If you want sort this issue you need to use JSONP or Iframes.
Install firebug and you will see an http 200 code and an error: that error is SOP acting.
You mentioned that you're checking the responseText property. Is it possible your response is in XML format?
If you send an XML request, or the response type is 'text/xml', you will get a value for responseXML. I believe that the responseText property can be blank if it's in XML format.
