I have tried switching from a previous Post request to a Get request. Which assumes its a Get but eventually does a post.
I tried the following in PHP :
curl_setopt($curl_handle, CURLOPT_POSTFIELDS, null);
curl_setopt($curl_handle, CURLOPT_POST, FALSE);
curl_setopt($curl_handle, CURLOPT_HTTPGET, TRUE);
What am I missing?
Additional information: I already have a connection that's setup to do a POST request. That completes successfully but later on when I try to reuse the connection and switch back to GET using the setopts above it still ends up doing a POST internally with incomplete POST headers. The problem is it believes its doing a GET but ends up putting a POST header without the content-length parameter and the connection fails witha 411 ERROR.
Solved: The problem lies here:
I set POST
via both _CUSTOMREQUEST
and _POST
and the _CUSTOMREQUEST
persisted as POST
while _POST
switched to _HTTPGET
. The Server assumed the header from _CUSTOMREQUEST
to be the right one and came back with a 411.
curl_setopt($curl_handle, CURLOPT_CUSTOMREQUEST, 'POST');
Make sure that you're putting your query string at the end of your URL when doing a GET request.
$qry_str = "?x=10&y=20"; $ch = curl_init(); // Set query data here with the URL curl_setopt($ch, CURLOPT_URL, 'http://example.com/test.php' . $qry_str); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_TIMEOUT, 3); $content = trim(curl_exec($ch)); curl_close($ch); print $content;
With a POST you pass the data via the CURLOPT_POSTFIELDS option instead of passing it in the CURLOPT__URL. ------------------------------------------------------------------------- $qry_str = "x=10&y=20"; curl_setopt($ch, CURLOPT_URL, 'http://example.com/test.php'); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_TIMEOUT, 3); // Set request method to POST curl_setopt($ch, CURLOPT_POST, 1); // Set query data here with CURLOPT_POSTFIELDS curl_setopt($ch, CURLOPT_POSTFIELDS, $qry_str); $content = trim(curl_exec($ch)); curl_close($ch); print $content;
Note from the curl_setopt()
docs for CURLOPT_HTTPGET
(emphasis added):
[Set CURLOPT_HTTPGET equal to]
TRUE
to reset the HTTP request method to GET.
Since GET is the default, this is only necessary if the request method has been changed.
CURL request by default is GET, you don't have to set any options to make a GET CURL request.
Add this before calling curl_exec($curl_handle)
curl_setopt($curl_handle, CURLOPT_CUSTOMREQUEST, 'GET');
