cURL, php request_headers 从 Apache2.2 到 Oracle App Server

Question

我已经在这个问题上敲了很久。我希望有人能帮我解决这个问题。我不确定我的问题是由 cURL、php、Apache、Oracle 还是脑放屁引起的。

我正在尝试发布到 Oracle 服务器上的表单。手动，我可以制作一个类似于 GET 的 url，它会显示正确的页面。我想做 POST 来隐藏变量（可能有很多变量），因为原始表单的方法是 POST。无论哪种方式，我都无法通过我的 php/cURL 程序获得响应。

我的具体问题：

• 显而易见的，为什么它不起作用？
• 为什么我可以手动而不是程序来完成请求？
• 为什么 access.log 里面有一个 GET？
• 为什么我的请求标头被重写以包含 Oracle 服务器的 /DAD/scheme/app？
• 我的编程自我会不会一样？

这是我当前的代码：

*<?php

$error_dump = 'stderr.txt';
$error_dump_handle = fopen($error_dump,'a');
$ch = curl_init();
$url = 'http://www2.blah.com/pls/blah/blah.blaQuery';
$url_enc_fields = array(
    'LAST_NAME'  => 'MacBlahBlah',            
    'FIRST_NAME' => 'Blahberina',          
    'CONTAINS' => 'Y',
        ... and more fields ...
    );              
$url_enc_fields = http_build_query($url_enc_fields);

//$url = $url.'?'.$url_enc_fields;  //previous GET attempt
$content_length = strlen($url_enc_fields);// number of bytes
$content_length = 'Content-Length:' . $content_length;
$headers = array(
    'Request: POST ' . $url_enc_fields . 'HTTP/1.1',  //An attempt to force the request
    'Accept: */*',
    'Content-Type: application/x-www-form-urlencoded',
    'Referer:http://blah.com/pls/blah/blah.startup?code1=MM&code2=bleep',               
    'Expect: ',
    $content_length
    );

curl_setopt($ch,CURLOPT_HEADER,1); 
curl_setopt($ch,CURLOPT_HTTPHEADER,$headers);
curl_setopt($ch,CURLINFO_HEADER_OUT,TRUE);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,FALSE); 
curl_setopt($ch,CURLOPT_FOLLOWLOCATION,TRUE);  // one of many guesses
curl_setopt($ch,CURLOPT_FRESH_CONNECT,TRUE);
// NOTE: no cookies or passwords involved             
curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,180);
curl_setopt($ch,CURLOPT_TIMEOUT,180);

curl_setopt($ch,CURLOPT_VERBOSE,TRUE);
curl_setopt($ch,CURLOPT_STDERR,$error_dump_handle);
curl_setopt($ch,CURLOPT_ENCODING,'chunked'); // Added because the response was chunked, no difference
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_POST,TRUE); // Apparently futile
curl_setopt($ch,CURLOPT_POSTFIELDS,$url_enc_fields);             
$postResult = curl_exec($ch);
$info = curl_getinfo($ch);   
$pretty_info = print_r($info,true);

> echo '<br/><pre>'; print_r($info); print_r($url_enc_fields);
> print_r($headers);

echo '</pre>';
$now_time = getdate();$format = '-------------- %f -----------';
fprintf($error_dump_handle,$format,$now_time[0]);
fprintf($error_dump_handle,$pretty_info);   
fprintf($error_dump_handle,curl_error($ch));    
fclose($error_dump_handle); 
curl_close($ch); 
?>*

为什么要执行 GET？

Answer 1

试试

$fields = array(
    'LAST_NAME'  => 'MacBlahBlah',            
    'FIRST_NAME' => 'Blahberina',          
    'CONTAINS' => 'Y',
        ... and more fields ...
    );              
$url_enc_fields = http_build_query($fields);

然后

curl_setopt($ch,CURLOPT_POST,count($fields)); // Apparently futile
curl_setopt($ch,CURLOPT_POSTFIELDS,$url_enc_fields);

我没有检查这些更改，但我通常是这样做的
