如何解析响应报头在PHP？ [英] How to parse response headers in PHP?

问题描述

我做了一个OAuth签名的请求到REST API并具有响应头在这样一个数组：

I have made an oauth signed request to a REST API and have the response headers in an array like so:

[0] => HTTP/1.1 200 OK
[1] => Cache-Control: private
[2] => Transfer-Encoding: chunked
[3] => Content-Type: text/html; charset=utf-8
[4] => Content-Location: https://***
[5] => Server: Microsoft-IIS/7.0
[6] => Set-Cookie: ASP.NET_SessionId=***; path=/; HttpOnly
[7] => X-AspNetMvc-Version: 2.0
[8] => oauth_token: ***
[9] => oauth_token_secret: ***
[10] => X-AspNet-Version: 4.0.30319
[11] => X-Powered-By: ASP.NET
[12] => Date: Sat, 15 Sep 2012 02:01:15 GMT

我试图找出如何解析的项目便于检索的头，比如HTTP状态code，内容位置，组oauth_token，和oauth_token_secret？

I am trying to figure out how to parse the headers for easy retrieval of items such as the HTTP status code, Content-Location, oauth_token, and oauth_token_secret?

推荐答案

您将需要遍历数组和检查 stripos函数（）来找到你的头寻找。在大多数情况下，你再爆炸（）在：（限制为2产生的部分），但HTTP响应$ C $按c需要你发生爆炸的空间。

You'll need to iterate the array and check stripos() to find the header you're looking for. In most cases, you then explode() on : (limiting to 2 resultant parts), but the HTTP response code will require you to explode on the spaces.

// Get any header except the HTTP response...
function getResponseHeader($header) {
  foreach ($response as $key => $r) {
     if (stripos($r, $header) !== FALSE) {
        list($headername, $headervalue) = explode(":", $r, 2);
        return trim($headervalue);
     }
  }
}
// example:
echo getResponseHeader("Content-Type");
// text/html; charset=utf-8

// Get the HTTP response code
foreach ($response as $key => $r) {
  if (stripos($r, 'HTTP/1.1') !== FALSE) {
    list(,$code, $status) = explode(' ', $r);
    echo "Code: $code, Status: $status";
    break;
  }
}
