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.
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 $content;
Note from the curl_setopt()
docs for CURLOPT_HTTPGET
(emphasis added):
[Set CURLOPT_HTTPGET equal to]
TRUE
to reset the HTTP request method to GET.
Since GET is the default, this is only necessary if the request method has been changed.
在调用 curl_exec($curl_handle) 之前添加这个
curl_setopt($curl_handle, CURLOPT_CUSTOMREQUEST, 'GET');
Solved: The problem lies here:
I set POST
via both _CUSTOMREQUEST
and _POST
and the _CUSTOMREQUEST
persisted as POST
while _POST
switched to _HTTPGET
. The Server assumed the header from _CUSTOMREQUEST
to be the right one and came back with a 411.
curl_setopt($curl_handle, CURLOPT_CUSTOMREQUEST, 'POST');
CURL 请求默认为 GET,您无需设置任何选项即可发出 GET CURL 请求。
