向oauth / request_token发送的Twitter API curl请求返回null-PHP 5.6

Question

因此，我有一个非常简单的应用程序，必须将其发布到自己的个人资料中，基本上就是这样。

据我目前所知，我需要经过三足的oauth来获取我的令牌，根据我的阅读，该令牌基本上可以永久使用，这很好。

无论如何，我正在做一个小实验，我将自己的方式卷曲到需要发布的oauth令牌中。

这是代码：

<?php


/*
The Request I wanna make, as described basically here: https://developer.twitter.com/en/docs/basics/authentication/api-reference/request_token
Part of this flow: https://developer.twitter.com/en/docs/basics/authentication/overview/3-legged-oauth

curl -XPOST
  --url 'https://api.twitter.com/oauth/request_token'
  --header 'OAuth
  oauth_nonce="K7ny27JTpKVsTgdyLdDfmQQWVLERj2zAK5BslRsqyw",

  oauth_callback="http%3A%2F%2Fmyapp.com%3A3005%2Ftwitter%2Fprocess_callback",
  oauth_signature_method="HMAC-SHA1",
  oauth_timestamp="1300228849",
  oauth_consumer_key="OqEqJeafRSF11jBMStrZz",
  oauth_signature="Pc%2BMLdv028fxCErFyi8KXFM%2BddU%3D",
  oauth_version="1.0"'
*/

$request_url = "https://api.twitter.com/oauth/request_token";

$consumer_secret = '[Consumer secret from my apps details > keys & tokens]';
$token_secret = '[token secret I got from my apps details > keys & tokens]';

$signature_key = "$consumer_secret&$token_secret";


$time = time();
$nonce = hash('md5', $time);
$callback = urlencode('http://localhost:8000/admin/twitter.callback.php');
$signature_method = "HMAC-SHA1";
$consumer_key = '[key from my apps detials > keys & tokens]';
$oauth_version = '1.0';

$payload = "oauth_nonce=$nonce&oauth_callback=$callback&oauth_signature_method=$signature_method&oauth_timestamp=$time&oauth_consumer_key=$consumer_key&oauth_version=1.0";

$to_be_signed = "POST&" . urlencode($request_url) . "&" . urlencode($payload);

$signature = base64_encode(hash_hmac('sha1', $to_be_signed, $signature_key, true));



$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $request_url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST,       true);
curl_setopt($ch, CURLOPT_TIMEOUT, 20);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Authorization: " . "OAuth
oauth_nonce=\"$nonce\",

oauth_callback=\"$callback\",
oauth_signature_method=\"$signature_method\",
oauth_timestamp=\"$time\",
oauth_consumer_key=\"$consumer_key\",
oauth_signature=\"$signature\",
oauth_version=\"$oauth_version\""));

$result = json_decode(curl_exec($ch), true);


curl_close($ch);

var_dump($result);
// prints out NULL.

这里出了点问题，我就是不知道。

先感谢您。

编辑：

将标题更改为：

curl_setopt($ch, CURLOPT_HTTPHEADER, array("OAuth
oauth_nonce=\"$nonce\",

oauth_callback=\"$callback\",
oauth_signature_method=\"$signature_method\",
oauth_timestamp=\"$time\",
oauth_consumer_key=\"$consumer_key\",
oauth_version=\"$oauth_version\",
oauth_signature=\"$signature\""));

将产生以下输出：

array(1) {
  ["errors"]=>
  array(1) {
    [0]=>
    array(2) {
      ["code"]=>
      int(215)
      ["message"]=>
      string(24) "Bad Authentication data."
    }
  }
}
