我试图实施“用Twitter登录”
我在这里看到了很多关于这个主题的问题,我已经阅读了很多这些问题并且一直坚持下去
我使用了以下链接:
implementing Sign in with Twitter
POST oauth/request_token
Creating a signature
Authorizing a request
,结果是响应:无法验证oauth签名和令牌(可能是最常见的错误=))
我做了什么:
date_default_timezone_set('UTC');
$oauth_consumer_key = 'mYOauThConsuMerKey'; //from app settings
function generate_nonce() {
$mt = microtime();
$rand = mt_rand();
return md5($mt . $rand); // md5s look nicer than numbers
}
$oauth_nonce = generate_nonce();
$http_method = 'POST';
$base_url = 'https://api.twitter.com/oauth/request_token';
$oauth_signature_method = 'HMAC-SHA1';
$oauth_timestamp = time();
$oauth_token = 'mytokenFromAPPsettoings';
$oauth_version = '1.0';
$oauth_callback = 'http://twoends.home/backend';
$params = array(
rawurlencode('oauth_nonce')=>rawurlencode($oauth_nonce),
rawurlencode('oauth_callback')=>rawurlencode($oauth_callback),
rawurlencode('oauth_signature_method')=>rawurlencode($oauth_signature_method),
rawurlencode('oauth_timestamp')=>rawurlencode($oauth_timestamp),
rawurlencode('oauth_token')=>rawurlencode($oauth_token),
rawurlencode('oauth_version')=>rawurlencode($oauth_version),
);
ksort($params);
$parameter_string = http_build_query($params,'','&');
$base_string = strtoupper($http_method).'&';
$base_string .= rawurlencode($base_url).'&';
$base_string .= rawurlencode($parameter_string);
$oauth_consumer_secret = 'myappconsumersecret';
$oauth_token_secret = 'mytokensecret';
$oauth_signing_key =rawurlencode($oauth_consumer_secret).'&'.rawurlencode($oauth_token_secret);
$oauth_signature = base64_encode(hash_hmac('sha1', $base_string, $oauth_signing_key, true));
$DST ='OAuth ';
foreach($params as $key=>$value){
$DST .= $key.'='.'"'.$value.'"&';
}
$DST = rtrim($DST,'&');
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $base_url);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Authorization: '.$DST));
curl_setopt($ch, CURLINFO_HEADER_OUT, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($ch);
$info = curl_getinfo($ch);
curl_close($ch);
所以,这段代码很挣扎,但仍然会产生错误
在一个主题中,我已经读过在这个阶段不需要令牌:有或没有 - 没有关系 - 仍然是同样的错误
试图玩时间(设置UTC) - 同样的错误
我也尝试使用像this这样的代码,但这对我不起作用
为什么我不使用某人的lib - 因为我想逐步通过算法,但我已经厌倦了它并且需要帮助

您的代码似乎有些问题:
1)你的params数组应该包含oauth_consumer_key而不是oauth_token
$params = array(
rawurlencode('oauth_nonce')=>rawurlencode($oauth_nonce),
rawurlencode('oauth_callback')=>rawurlencode($oauth_callback),
rawurlencode('oauth_signature_method')=>rawurlencode($oauth_signature_method),
rawurlencode('oauth_timestamp')=>rawurlencode($oauth_timestamp),
rawurlencode('oauth_consumer_key')=>rawurlencode($oauth_consumer_key),
rawurlencode('oauth_version')=>rawurlencode($oauth_version),
);
2)请求令牌的签名密钥应使用oauth_consumer_secret后跟&符号构建:
$ oauth_signing_key = rawurlencode($ oauth_consumer_secret)。'&';
3)您似乎没有在Authorization标头中的任何位置设置签名。做:
$DST ='OAuth ';
foreach($params as $key=>$value){
$DST .= $key.'='.'"'.$value.'"&';
}
$DST .= 'oauth_signature='.rawurlencode($oauth_signature)

我想重新审视问题并发布新数据
感谢@Jonny S我发现了一些错误并且又出现了另一个错误=)
所以,我的工作流程现在看起来:
生成随机数的函数,附加信息:oauth_nonce in api,oauth.net
function generate_nonce() {
$mt = microtime();
$rand = mt_rand();
return md5($mt . $rand); // md5s look nicer than numbers
}
Implementing Sign in with Twitter(此链接会向我们显示我们应提前发布的标题),并向我们显示移动方向 - POST oauth/request_token
此页面链接到oauth docs section 6.1
在那里我们可以找到请求令牌所需的参数,但在官方文档中你找不到“oauth_calback”参数,它是twitter API中必需的参数!
我要做的下一步 - 收集所需的参数:
oauth_consumer_key
$oauth_consumer_key = 'YoUrS KEy FrOm aPP ApI';
oauth_nonce
$oauth_nonce = generate_nonce();
oauth_callback
$oauth_callback = 'http://twoends.home/backend';
oauth_sinature_method
$oauth_signature_method = 'HMAC-SHA1';
oauth_timestamp
$oauth_timestamp = time();
oauth_version
$oauth_version = '1.0';
其他参数(过程中需要):
基本网址
$ base_url ='https://api.twitter.com/oauth/request_token';
HTTP方法
$ http_method ='POST';
OAuth签名(最棘手的部分)
此处我们有一个关于如何操作的API页面Creating a signature
首先我们需要收集所有需要的参数,百分比编码和排序,我把它们推到数组:
$params = array(
rawurlencode('oauth_consumer_key')=>rawurlencode($oauth_consumer_key),
rawurlencode('oauth_nonce')=>rawurlencode($oauth_nonce),
rawurlencode('oauth_callback')=>rawurlencode($oauth_callback),
rawurlencode('oauth_signature_method')=>rawurlencode($oauth_signature_method),
rawurlencode('oauth_timestamp')=>rawurlencode($oauth_timestamp),
rawurlencode('oauth_version')=>rawurlencode($oauth_version),
);
然后排序:
ksort($params);
然后我正在创建参数字符串:
$parameter_string = http_build_query($params,'','&');
结果:
PARAM字符串:oauth_callback = HTTP%253A%252F%252Ftwoends.home%252Fbackend&安培; oauth_consumer_key = oauth_consumer_key_wQjQ7u5lgwA&安培; oauth_nonce = 46fa649c21ac5315d4d4510ff68ad630&安培; oauth_signature_method = HMAC-SHA1&安培; oauth_timestamp = 1381930918&安培; oauth_version = 1.0
接下来我需要创建base_string,它将用于创建签名作为hash_hmac()函数的数据参数
$base_string = strtoupper($http_method).'&';
$base_string .= rawurlencode($base_url).'&';
$base_string .= rawurlencode($parameter_string);
结果:
POST&安培; HTTPS%3A%2F%2Fapi.twitter.com%2Foauth%2Frequest_token&安培; oauth_callback%3Dhttp%25253A%25252F%25252Ftwoends.home%25252Fbackend%26oauth_consumer_key%3Dapp_cons_keyQjQ7u5lgwA%26oauth_nonce%3D46fa649c21ac5315d4d4510ff68ad630%26oauth_signature_method%3DHMAC-SHA1%26oauth_timestamp %3D1381930918%26oauth_version%3D1.0
接下来我从APP设置获取consumer_secret以创建签名密钥,该签名密钥将用于在hash_hmac()函数中创建签名作为第三个参数
$oauth_consumer_secret = 'consumer_secret_from_app_settings';
$oauth_signing_key = rawurlencode($oauth_consumer_secret).'&';
有一点需要提及:第一步(request_token我们不需要放任何令牌)
此步骤创建签名:
$oauth_signature = base64_encode(hash_hmac('sha1', $base_string, $oauth_signing_key, true));
现在我们需要为params数组添加签名并构建头字符串
$params['oauth_signature'] = rawurlencode($oauth_signature);
ksort($params);
找到构建标题字符串
$DST ='OAuth ';
foreach($params as $key=>$value){
$DST .= $key.'='.'"'.$value.'", ';
}
$DST = rtrim($DST,', ');
//or we can make it by hand as below
//$DST .= 'oauth_nonce="'.rawurlencode($oauth_nonce)
// .'", oauth_callback="'.rawurlencode($oauth_callback)
// .'", oauth_signature_method="HMAC-SHA1", oauth_timestamp="'
// .rawurlencode($oauth_timestamp).'", oauth_consumer_key="'
// .rawurlencode($oauth_consumer_key).'", oauth_signature="'
// .rawurlencode($oauth_signature).'", oauth_version="1.0"';
最后一步(我希望)是发送请求:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $base_url);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Authorization: '.$DST));
curl_setopt($ch, CURLINFO_HEADER_OUT, 1);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($ch);
$info = curl_getinfo($ch);
curl_close($ch);
echo '<pre>';
print_r($info);
echo '</pre>';
此代码产生错误400 - 错误请求
如果我删除curl_setopt($ ch,CURLOPT_POST,true);我得到错误 - 401

希望这有助于了解在哪里找到错误,提前我还会尝试使用Fiddler跟踪请求
---------------------------------------
通过使用新API解决
答案 2 :(得分:0)
看起来oauth_callback网址在basetring中被三重编码。它应该是以下形式:
POST&https%3A%2F%2Fapi.twitter.com%2Foauth%2Frequest_token&
oauth_callback%3Dhttp%253A%252F%252Ftwoends.home%252Fbackend%26
oauth_consumer_key%3Dapp_cons_keyQjQ7u5lgwA ...
在你的基础字符串中:
oauth_callback%3Dhttp%25253A%25252F%25252Ftwoends.home%25252Fbackend
罪魁祸首似乎是'http_build_query'。
