解析多个 headers 同名
Parse multiple headers with same name
我想在我的应用程序中正确实施 header 解析。但是，例如，让我们有 headers，例如：
HTTP/1.1 200 OK
...
Foo: Bar
Foo: Baz
在这种情况下，仅使用 getallheaders() returns Foo => Bar 并丢弃 Baz 值。有没有其他方法可以获取所有 header 值？
根据 this bug report，这似乎取决于您为 PHP 使用的 SAPI。基本的 question/statement 是：
If I make request:
GET / HTTP/1.1
Forwarded: for=10.0.0.1,for=20.30.40.50;host=php.net,host=awesome.proxy.com;proto=https,proto=http
Forwarded: for=10.30.20.10;host=second.awesome.proxy.com;proto=http
I get 3 different responses based on SAPI
- FPM只保留最后一个header
- php -s 只保留第一个 header
- apache 用 ,
连接它们
对工单的回复是：
The ability to get headers is highly dependent on the SAPI. Apache's works nicely, but php -s is just a quick development server that is not going to be suitable for all purposes.
So really, the issue here is that php-fpm doesn't properly handle multiple headers. The HTTP spec requires that multiple headers only be allowed when their values can be combined into comma-separated lists, which means $_SERVER and getallheaders() are still sufficient.
