我正在尝试测试这个示例,我找到了
here,这样我就可以在客户端进行直接上传,而无需用户使用Google云端存储登录.
表达的所有常量都有正确的值,路径正确且没有空内容.
我得到的错误:
openssl_sign(): supplied key param cannot be coerced into a private key
我实现的功能是:
public static function storageURL( $id,$method = 'GET',$duration = 10 ) { $key = file_get_contents(self::KEY_FILE); $pkey = openssl_get_privatekey($key,'notasecret'); $expires = time( ) + $duration; $content_type = ($method == 'PUT') ? 'application/x-www-form-urlencoded' : ''; $to_sign = ($method . "\n" . /* Content-MD5 */ "\n" . $content_type . "\n" . $expires . "\n" . '/'.self::BUCKET_NAME.'/' . $id); $signature = '*Signature will go here*'; if (!openssl_sign( $to_sign,$signature,$pkey,'sha256' )) { error_log( 'openssl_sign Failed!' ); $signature = '<Failed>'; } else { $signature = urlencode( base64_encode( $signature ) ); } return ('https://'.self::BUCKET_NAME.'.commondatastorage.googleapis.com/' . $id . '?GoogleAccessId=' . self::SERVICE_ACCOUNT_NAME . '&Expires=' . $expires . '&Signature=' . $signature); }
首先,您需要使用openssl_pkcs12_read来读取密钥文件,而不是file_get_contents.其次,我相信你想把第二个参数留给openssl_get_privatekey.
