如何在服务器上启用HTTP_RANGE [英] How to enable the use of HTTP_RANGE on server

问题描述

如果我运行以下脚本来测试服务器上的HTTP_RANGE，我会得到一个否响应。我的LAMP服务器中有什么东西我需要为此设置给我一个是吗？我似乎无法找到关于此的任何信息，只能测试它是否存在。

If I run the following script to test for HTTP_RANGE on my server I get a 'no' response. Is there something in my LAMP server that I need to set for this to give me a yes? I can't seem to find any info regarding this, only how to test for it's existence.

<?php
if (isset($_SERVER['HTTP_RANGE'])) {
    echo "yes";
} elseif (isset($_ENV['HTTP_RANGE'])) {
    echo "yes";
} else {
    echo "no";
}

推荐答案

此变量仅在客户端（'用户代理'）发出请求，询问某些字节范围（Accept-Ranges请求头）而不是整个文档。这些不是针对常规请求定义的。您确定您的用户代理要求字节范围吗？

This variable is only present if the client ('user agent') makes a request asking for certain range of bytes (a Accept-Ranges request header) instead of the whole document. These are not defined for regular requests. Are you sure that your user agent asks for byte range?
