php-如何正确处理分块编码请求？

我有两个网站：一个使用PHP的Lighttpd,另一个使用Apache的网站,并且这两个站点都不能正确处理分块传输编码.

我是从手机J2ME发送此请求的,因此无法将此传输类型更改为其他任何类型.

因此,我唯一的方法是以其他方式处理分块传输编码请求.只要能在我的CentOS服务器上启用它并安装和更改所有必要的东西,任何解决方案都将是好的.

所以我的问题是：如何在服务器端正确处理分块编码请求？

解决方法:

编辑：
您正在运行哪个版本的PHP / Apache / LightHTTP？以前在PHP中有this bug,但是5.2.13和5.3.2似乎已经不存在了.

如果上面的链接没有帮助,我想确切地了解PHP所看到的内容,您可以将其放在api中并发布结果吗？ (当然,请编辑).

$input = file_get_contents('php://input');
$stdin = file_get_contents('php://stdin');

print "FILES: ";
print_r($_FILES);

print("<br>POST: ");
print_r($_POST);

print("<br>input: ".$input);
print("<br>stdin: ".$stdin);
die;

这样,我们可以看到PHP所看到的内容,如果它没有解码分块编码,那么我们可以手动对其进行解码.

结束编辑. (留在下面,以防其他人觉得有用)

我认为这是您先前问题的跟进.我假设您正在从PHP中读取流？

我是几年前写的,它从分块的编码流中读取数据,然后您可以对输出执行任何操作.如果文件很大,则不要将其读取为字符串,而应写入文件.

<?php
define('CRLF', "\r\n");
define('BUFFER_LENGTH', 8192);
$headers = '';
$body = '';
$length = 0;

$fp = fsockopen($host, $port, $errno, $errstr, $timeout);

// get headers FIRST
do
{
    // use fgets() not fread(), fgets stops reading at first newline
    // or buffer which ever one is reached first
    $data = fgets($fp, BUFFER_LENGTH);
    // a sincle CRLF indicates end of headers
    if ($data === false || $data == CRLF || feof($fp)) {
        // break BEFORE OUTPUT
        break;
    }
    $headers .= $data;
}
while (true);
// end of headers

// read from chunked stream
// loop though the stream
do
{
    // NOTE: for chunked encoding to work properly make sure
    // there is NOTHING (besides newlines) before the first hexlength

    // get the line which has the length of this chunk (use fgets here)
    $line = fgets($fp, BUFFER_LENGTH);

    // if it's only a newline this normally means it's read
    // the total amount of data requested minus the newline
    // continue to next loop to make sure we're done
    if ($line == CRLF) {
        continue;
    }

    // the length of the block is sent in hex decode it then loop through
    // that much data get the length
    // NOTE: hexdec() ignores all non hexadecimal chars it finds
    $length = hexdec($line);

    if (!is_int($length)) {
        trigger_error('Most likely not chunked encoding', E_USER_ERROR);
    }

    // zero is sent when at the end of the chunks
    // or the end of the stream or error
    if ($line === false || $length < 1 || feof($fp)) {
        // break out of the streams loop
        break;
    }

    // loop though the chunk
    do
    {
        // read $length amount of data
        // (use fread here)
        $data = fread($fp, $length);

        // remove the amount received from the total length on the next loop
        // it'll attempt to read that much less data
        $length -= strlen($data);

        // PRINT out directly
        #print $data;
        #flush();
        // you could also save it directly to a file here

        // store in string for later use
        $body .= $data;

        // zero or less or end of connection break
        if ($length <= 0 || feof($fp))
        {
            // break out of the chunk loop
            break;
        }
    }
    while (true);
    // end of chunk loop
}
while (true);
// end of stream loop

// $body and $headers should contain your stream data
?>
