编辑：
您运行的是哪个版本的 PHP/Apache/LightHTTP？正如有this bug http://bugs.php.net/bug.php?id=50210之前在 PHP 中，但似乎在 5.2.13 和 5.3.2 中消失了。
如果上面的链接没有帮助，我想确切地知道 PHP 看到了什么，你能把它放在你的 api 中并发布结果吗？ （当然是编辑过的）。
$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;
这样我们就可以看到 PHP 所看到的内容，如果它没有解码分块编码，那么我们可以手动解码它。
结束编辑。 （留下下面的内容以防其他人觉得有用）
我认为这是您之前问题的后续。我假设您正在从 PHP 读取流？
我几年前写过这个，它从分块编码流中读取，然后您可以对输出执行任何您想要的操作。如果它是一个大文件，请不要将其读入字符串，而是写入文件。
<?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
?>
