Curl : * 违反 RFC 2616/10.3.2 并从 POST 切换到 GET

我正在使用 curl 发布到脚本.

curl_setopt ($ch, CURLOPT_POST, true);curl_setopt($ch,CURLOPT_URL,$url);curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);curl_setopt($ch,CURLOPT_POSTFIELDS,$postvars);curl_setopt($ch, CURLOPT_VERBOSE, 1);curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);curl_setopt($ch,CURLOPT_SSL_VERIFYHOST,0);

但是涉及 301 重定向，这导致 curl 从 POST 切换到 GET.

<前>HTTP/1.1 301 永久移动<位置:https://myserver.org/php/callback-f.php<内容长度:0<日期:2011 年 11 月 16 日，星期三 17:21:06 GMT<服务器:lighttpd/1.4.28* 连接 #0 到主机 myserver.org 保持不变* 向这个 URL 发出另一个请求:'https://myserver.org/php/callback-f.php'* 违反 RFC 2616/10.3.2 并从 POST 切换到 GET* 即将连接()到 myserver.org 端口 443

有谁知道如何防止 curl 切换到 GET?

解决方案

CURLOPT_POSTREDIR 可以设置配置此行为(curl 中基于 301 位置标头的自动重定向的请求方法):

<块引用>

curl_setopt( , CURLOPT_POSTREDIR, 3);

此处 3 告诉 curl 模块重定向 301 和 302 请求.

0,1,2,3 是最后一个参数的有效选项.

0 ->不要设置任何行为
1 ->仅对 301 重定向使用相同类型的请求进行重定向.
2 ->仅对 302 重定向使用相同类型的请求进行重定向.
3 ->使用相同类型的请求对 301 和 302 重定向进行重定向.

另见:请求 #49571 CURLOPT_POSTREDIR 未实现，其中有一些有用的注释，例如设置自定义请求方法:

curl_setopt( $ch, CURLOPT_CUSTOMREQUEST, "POST");

I'm using curl to post to a script.

curl_setopt ($ch, CURLOPT_POST, true);
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch,CURLOPT_POSTFIELDS,$postvars);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch,CURLOPT_SSL_VERIFYHOST,0);

But there's 301 redirect involved which casues curl to switch from POST to GET.

HTTP/1.1 301 Moved Permanently
< Location: https://myserver.org/php/callback-f.php
< Content-Length: 0
< Date: Wed, 16 Nov 2011 17:21:06 GMT
< Server: lighttpd/1.4.28
* Connection #0 to host myserver.org left intact
* Issue another request to this URL: 'https://myserver.org/php/callback-f.php'
* Violate RFC 2616/10.3.2 and switch from POST to GET
* About to connect() to myserver.org port 443

Does anyone know how I can prevent curl from switching to GET please?

解决方案

CURLOPT_POSTREDIR can be set to configure this behaviour (request method for 301 location header based automatic redirects in curl):

curl_setopt( , CURLOPT_POSTREDIR, 3);

here 3 tells curl module to redirect both 301 as well as 302 requests.

0,1,2,3 are the valid options for the last argument.

0 -> do not set any behavior
1 -> follow redirect with the same type of request only for 301 redirects.
2 -> follow redirect with the same type of request only for 302 redirects.
3 -> follow redirect with the same type of request both for 301 and 302 redirects.

See as well: Request #49571 CURLOPT_POSTREDIR not implemented which has some useful comments, like setting a custom request method:

curl_setopt( $ch, CURLOPT_CUSTOMREQUEST, "POST");
