Question

我正在使用API，使用cURL我收到了一组数据。

数据似乎是一半HTTP请求和一半JSON。我不知道为什么它会混合，但基本上我在做var_dump时得到了这个回复：

string(873) "HTTP/1.1 200 OK cache-control: no-cache, no-store, must-revalidate, pre-check=0, post-check=0 content-length: 153 content-type: application/json;charset=utf-8 date: Mon, 10 Nov 2014 10:58:49 UTC expires: Tue, 31 Mar 1981 05:00:00 GMT last-modified: Mon, 10 Nov 2014 10:58:49 GMT ml: A pragma: no-cache server: tsa_b set-cookie: guest_id=v1%3A141561712923128379; Domain=.twitter.com; Path=/; Expires=Wed, 09-Nov-2016 10:58:49 UTC status: 200 OK strict-transport-security: max-age=631138519 x-connection-hash: 57175e4dba3d726bebb399072c225958 x-content-type-options: nosniff x-frame-options: SAMEORIGIN x-transaction: 2e4b8e053e615c75 x-ua-compatible: IE=edge,chrome=1 x-xss-protection: 1; mode=block {"token_type":"bearer","access_token":"AAAAAAAAAAAAAAAAAAAAAMVfbQAAAAAAK7qYRQOgdZ771TrJ6pZ7nugCwVQ%3DLKcongtwy3lcBDbPSEreC9DfhJk3Gm7qyQInqhFAxYvo1clv4S"}"

这是完整的数据。它在开头有HTTP信息，然后在最后部分JSON。

我需要的唯一一点是access_token数据。

如果它只是JSON，那么我可以使用json_decode来获取access_token但是因为它在开头json_decode获得了所有HTTP信息无法理解它并且给出结果NULL

如何删除HTTP部分以便我可以获取access_token数据？

ETA：我的请求是通过cURL发出的，因此我要转发的$response

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$auth_url);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "grant_type=client_credentials");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$header = curl_setopt($ch, CURLOPT_HEADER, 1);
$result = curl_exec($ch);
curl_close($ch);

我收到的结果大致与Twitter文档中给出的预期结果相符，所以我不认为数据已损坏/不正确：https://dev.twitter.com/oauth/reference/post/oauth2/token

$a='HTTP/1.1 200 OK cache-control: no-cache, no-store, must-revalidate, pre-check=0, post-check=0 content-length: 153 content-type: application/json;charset=utf-8 date: Mon, 10 Nov 2014 10:58:49 UTC expires: Tue, 31 Mar 1981 05:00:00 GMT last-modified: Mon, 10 Nov 2014 10:58:49 GMT ml: A pragma: no-cache server: tsa_b set-cookie: guest_id=v1%3A141561712923128379; Domain=.twitter.com; Path=/; Expires=Wed, 09-Nov-2016 10:58:49 UTC status: 200 OK strict-transport-security: max-age=631138519 x-connection-hash: 57175e4dba3d726bebb399072c225958 x-content-type-options: nosniff x-frame-options: SAMEORIGIN x-transaction: 2e4b8e053e615c75 x-ua-compatible: IE=edge,chrome=1 x-xss-protection: 1; mode=block {"token_type":"bearer","access_token":"AAAAAAAAAAAAAAAAAAAAAMVfbQAAAAAAK7qYRQOgdZ771TrJ6pZ7nugCwVQ%3DLKcongtwy3lcBDbPSEreC9DfhJk3Gm7qyQInqhFAxYvo1clv4S"}"';

preg_match("/\{.*\}/",$a,$m);

$ja=json_decode($m[0]);
var_dump($ja,$m);

输出：

object(stdClass)[1]
  public 'token_type' => string 'bearer' (length=6)
  public 'access_token' => string 'AAAAAAAAAAAAAAAAAAAAAMVfbQAAAAAAK7qYRQOgdZ771TrJ6pZ7nugCwVQ%3DLKcongtwy3lcBDbPSEreC9DfhJk3Gm7qyQInqhFAxYvo1clv4S' (length=112)

Answer 2

切换标题输出并删除

$header = curl_setopt($ch, CURLOPT_HEADER, 1);

或替换为

curl_setopt($ch, CURLOPT_HEADER, false);

从部分JSON和部分HTTP响应中提取数据
