使用php处理http响应_兼容chunked和压缩的响应

handle_http_response.php

<?php

function http_unchunk($data) {
    $res=[];
    $p=0; $n=strlen($data);
    while($p<$n) {
        if (preg_match("/^([0-9A-Fa-f]+)\r\n/",substr($data,$p,18),$m)) {
            $sz=hexdec($m[1]); $p+=strlen($m[0]);
            $res[]=substr($data,$p,$sz); $p+=$sz+2;
        } else {
            break;
        }
    }
    return implode('',$res);
}

//if Content-Encoding is gzip or x-gzip or x-compress use gzdecode
//if Content-Encoding is deflate use gzdeflate

if ($chunked) $body=http_unchunk($body);
if ($gzip) $body=gzdecode($body);
if ($deflate) $body=gzdeflate($body);
