很抱歉给您带来另一个“无法验证 oauth 签名和 token ”错误，但我无法弄清楚我的请求有什么问题。
我正在从这个字符串构建我的签名:
POST&http%3A%2F%2Fapi.twitter.com%2Foauth%2Frequest_token&oauth_callback%3Dhttp%3A%2F%2Fcraiga.id.au%2Ftwitter%2Fconnected%26oauth_consumer_key%3Dtm5...DOg%26oauth_nonce%3D8...22b%26oauth_signature_method%3DHMAC-SHA1%26oauth_timestamp%3D1275453048%26oauth_version%3D1.0
由此，我使用以下 PHP 代码生成了一个 28 个字符的签名:
base64_encode(hash_hmac('sha1', $raw, 'YUo...HIU' . '&', true));
使用此签名，我发送以下请求:
POST http://api.twitter.com/oauth/request_token HTTP/1.1

Failed to validate oauth signature and token
如果有人能解释为什么这可能会失败，我很乐意听到。
最佳答案
您使用了错误的信息来生成签名。 你应该使用 ...
oauth_callback=http%3A%2F%2Fcraiga.id.au%2Ftwitter%2Fconnected&oauth_consumer_key=tm5...DOg&oauth_nonce=3D8...22b&oauth_signature_method=HMAC-SHA1&oauth_timestamp= 1275453048&oauth_version=1.0
... 生成签名(阅读:不使用“POST”和请求 URI)
