尝试使用 Delphi RESTClient 通过基于 token 的身份验证来使用/调用 NetSuite ReSTLet。我有一个有效的 Postman 请求,用于验证所需的所有授权参数。缺少一个参数 -realm - 当添加到代码中时,确实会更改从 NetSuite 端返回的错误消息,但仍然不会导致成功调用。
procedure TForm1.OAuth1Authenticator1Authenticate(ARequest: TCustomRESTRequest;
var ADone: Boolean);
begin
// XXXXXXX_RP is a NetSuite account number and environment
ARequest.AddAuthParameter('realm','XXXXXX_RP',pkQUERY);
end;
如果不添加realm(上面代码被注释掉)则返回的剩余内容为:
error code: USER_ERROR
error message: header is not NLAuth scheme [ OAuth oauth_consumer_key="fe8da7b31dccbd47e90e5dd5e641fe7b0cbff032a951b4058618c207caf569f8", oauth_nonce="c98fa9de2c601f45bdc8d5c640f1b3cf", oauth_signature_method="HMAC-SHA1", oauth_signature="PfCQE3A4DicTtCfpBEPmbSOmqNg%3D", oauth_timestamp="1568639138", oauth_token="a8190ba34e223f25b32cdb4837d9e1973b8fd6208804e93306f4618ccdb6d648", oauth_version="1.0" ]
添加领域后我仍然得到:
error code: INVALID_LOGIN_ATTEMPT
error message: Invalid login attempt.
有人使用 Delphi RESTClient 成功调用 NetSuite ReSTLet 吗?
更新:看起来它不支持使用可选的领域参数。手动添加它会将其添加到规范化参数列表中,以便在不应该进行签名时进行签名。我修改了TOAuth1SignatureMethod_HMAC_SHA1.BuildSignature
在REST.Authenticator.OAuth
跳过此参数(只是在一些代码周围添加了 if Lparam.Name <> 'realm' then begin .. end;
block ),但仍然没有成功向 NetSuite 发出请求。阅读 https://oauth.net/core/1.0/ 后这样做了第 9.1.1 节。规范化请求参数:
The request parameters are collected, sorted and concatenated into a normalized string:
- Parameters in the OAuth HTTP Authorization header excluding the realm parameter.
- Parameters in the HTTP POST request body (with a content-type of application/x-www-form-urlencoded).
- HTTP GET parameters added to the URLs in the query part (as defined by [RFC3986] section 3).
最佳答案
最终通过 Indy 手动组装请求。下面是组装 AUTH header 的部分的副本,以及使用 Indy 的 IdHTTP 执行测试请求的代码。注意:Netsuite 帐号和 ID/ secret 仅供展示。

注意:代码已更新为使用 SHA256 而不是 SHA1 进行 OAUTH 签名。 NetSuite 已发出通知,他们将在 NetSuite 版本 2021.2 中要求这样做。
